Configuration Devices for ACEX, APEX, FLEX & Mercury Devices Data Sheet
Device Configuration
The control signals for configuration devices--nCS, OE, and DCLK-- interface directly with ACEX, APEX, FLEX, and Mercury device control signals. All ACEX, APEX, FLEX, and Mercury devices can be configured by a configuration device without requiring an external intelligent controller. The configuration device's OE and nCS pins control the tri-state buffer on the DATA output pin, and enable the address counter (and the oscillator in EPC2, EPC1, and EPC1441 devices). When OE is driven low, the configuration device resets the address counter and tri-states its DATA pin. The nCS pin controls the output of the configuration device. If nCS is held high after the OE reset pulse, the counter is disabled and the DATA output pin is tri-stated. When nCS is driven low, the counter and DATA output pin are enabled. When OE is driven low again, the address counter is reset and the DATA output pin is tri-stated, regardless of the state of nCS. 1 The EPC2, EPC1, and EPC1441 devices determine the operation mode and whether the ACEX 1K, APEX 20K, FLEX 10K, FLEX 8000, FLEX 6000, or Mercury protocols should be used when OE is driven high.
When the configuration device has driven out all of its data and has driven nCASC low, the device tri-states the DATA pin to avoid contention with other configuration devices. The EPC2 device allows the user to initiate configuration of the ACEX, APEX, FLEX, or Mercury device via an additional pin, nINIT_CONF, that can be tied to the nCONFIG pin of the ACEX, APEX, FLEX, or Mercury device(s) to be configured. A JTAG instruction causes the EPC2 device to drive nINIT_CONF low, which in turn pulls nCONFIG low. The EPC2 device then drives nINIT_CONF high to start configuration. When the JTAG state machine exits this state, nINIT_CONF releases nCONFIG and configuration is initiated. 1 An EPC2 device can be programmed with a POF generated for an EPC1 or EPC1441 device, however, an EPC2 device cannot configure FLEX 6000 or FLEX 8000 devices. An EPC1 device can be programmed using a POF generated for an EPC1441 device.

Configuration Devices for ACEX, APEX, FLEX & Mercury Devices Data Sheet
ACEX 1K, APEX 20K, FLEX 10K, FLEX 6000 & Mercury Device Configuration
ACEX 1K, APEX 20K, FLEX 10K, and Mercury devices can be configured with EPC2, EPC1, or EPC1441 devices. FLEX 6000 devices can be configured with EPC1 or EPC1441 devices. The EPC2, EPC1, or EPC1441 device stores configuration data in its EPROM array and serially clocks data out with an internal oscillator. The OE, nCS, and DCLK pins supply the control signals for the address counter and the output tri-state buffer. The configuration device sends a serial bitstream of configuration data to its DATA pin, which is routed to the DATA0 or DATA input pin on the ACEX 1K, APEX 20K, FLEX 10K, FLEX 6000, or Mercury device. Figure 4 shows an ACEX 1K, APEX 20K, FLEX 10K, FLEX 6000, or Mercury device configured with a single EPC2, EPC1, or EPC1441 device. Figure 4.

EPC2 cannot be used with FLEX 6000 devices. All other connections are the same for ACEX 1K, APEX 20K, FLEX 10K, FLEX 6000 and Mercury devices. All pull-up resistors are 1 k3/4. APEX 20KE pull up resistors are 10 k3/4. The OE, nCS, and nINIT_CONF pins on EPC2 devices have internal, user-configurable 1-k3/4 pull-up resistors. If internal pull-up resistors are used, external pull-up resistors should not be used on these pins. The nINIT_CONF pin is only available on EPC2 devices and has an internal pull up of 1 k3/4 that is always active. If nINIT_CONF is not available or not used, nCONFIG must be pulled to VCC either directly or through a 1-k3/4 resistor.

Description
Output
Serial data output. The DATA pin is tri-stated before configuration when the nCS pin is high, and after the configuration device finishes sending its configuration data. This operation is independent of the device's position in the cascade chain. DCLK is a clock output when configuring with a single configuration device or when the configuration device is the first device in a configuration device chain. DCLK is a clock input for subsequent configuration devices in a configuration device chain. Rising edges on DCLK increment the internal address counter and present the next bit of data to the DATA pin. The counter is incremented only if the OE input is held high, the nCS input is held low, and all configuration data has not been transferred to the target device. When configuring with the first EPC2 or EPC1 device in a configuration device chain or with a single EPC1441 device, the DCLK pin drives low after configuration is complete or when OE is low. Output enable (active high) and reset (active low). A low logic level resets the address counter. A high logic level enables DATA and permits the address counter to count. If this pin is low (reset) during configuration, the internal oscillator becomes inactive and DCLK drives low. See "Error Detection Circuitry" on page 17. Chip select input (active low). A low input allows DCLK to increment the address counter and enables DATA to drive out. If the EPC1 or EPC2 is reset with nCS low, the device initializes as the first device in a configuration chain. If the EPC1 or EPC2 device is reset with nCS high, the device initializes as the subsequent device in the chain. Cascade select output (active low). This output goes low when the address counter has reached its maximum value. In a chain of EPC1 or EPC2 devices, the nCASC pin of one device is connected to the nCS pin of the next device, which permits DCLK to clock data from the next EPC1 or EPC2 device in the chain.

VCCSEL must be connected to ground if the device uses a 5.0-V power supply (i.e., VCC = 5.0 V). VCCSEL must be connected to VCC if the device uses a 3.3-V power supply (i.e., VCC = 3.3 V). Mode select for VPP. VPPSEL must be connected to ground if VPP uses a 5.0-V power supply (i.e., VPP = 5.0 V). VPPSEL must be connected to VCC if VPP uses a 3.3-V power supply (i.e, VPP = 3.3 V). Programming power pin. For the EPC2 device, this pin is normally tied to VCC. If the EPC2 VCC is 3.3 V, VPP can be tied to 5.0 V to improve in-system programming times. For EPC1 and EPC1441 devices, VPP must be tied to VCC. Power pin.

Configuration Devices for ACEX, APEX, FLEX & Mercury Devices Data Sheet
ACEX 1K, APEX 20K, FLEX 10K, FLEX 6000 & Mercury Device Configuration with Multiple EPC2 or EPC1 Configuration Devices
When configuration data for ACEX 1K, APEX 20K, FLEX 10K, FLEX 6000, or Mercury devices exceeds the capacity of a single EPC2 or EPC1 device, multiple EPC2 or EPC1 devices can be cascaded together. (The EPC1441 device does not support data cascading.) If multiple EPC2 or EPC1 devices are required, the nCASC and nCS pins provide handshaking between the devices. When configuring ACEX 1K, APEX 20K, FLEX 10K, FLEX 6000, or Mercury devices with cascaded EPC2 or EPC1 devices, the position of the EPC2 or EPC1 device in the chain determines its operation. When the first or master device in a configuration device chain is powered-up or reset and the nCS pin is driven low, the master device controls configuration. The master device supplies all clock pulses to one or more ACEX, APEX, FLEX, or Mercury devices and to any subsequent slave devices during configuration. The master EPC2 or EPC1 device also provides the first stream of data to the ACEX, APEX, FLEX, or Mercury devices during multi-device configuration. After the master EPC2 or EPC1 device finishes sending configuration data, the master EPC2 or EPC1 device drives its nCASC pin low, which drives the nCS pin of the first slave EPC2 or EPC1 device low. This action causes the slave EPC2 or EPC1 device to send configuration data to the ACEX, APEX, FLEX, or Mercury devices. The master EPC2 or EPC1 device clocks all subsequent slave devices until configuration is complete. Once all configuration data is transferred and the nCS pin on the master EPC2 or EPC1 device is driven high by the ACEX, APEX, FLEX, or Mercury device's CONF_DONE pin, the master EPC2 or EPC1 device clocks 16 additional cycles to initialize the ACEX, APEX, FLEX, or Mercury device(s). The master EPC2 or EPC1 device then goes into zero-power (idle) state. If nCS on the master EPC2 or EPC1 device is driven high before all configuration data is transferred, or if nCS is not driven high after all configuration data is transferred, the master EPC2 or EPC1 device drives the ACEX, APEX, FLEX, or Mercury device's nSTATUS pin low, indicating a configuration error. Configuration automatically restarts if the project is compiled with the Auto-Restart Configuration on Frame Error option turned on in the MAX+PLUS II software's Global Project Device Options dialog box (Assign menu). Figure 5 shows an ACEX 1K, APEX 20K, FLEX 10K, FLEX 6000, or Mercury device configured with two EPC2 or EPC1 devices. Additional EPC2 or EPC1 devices can be added by connecting nCASC to nCS of the subsequent slave EPC2 or EPC1 device in the chain and connecting DCLK, DATA, and OE in parallel.

If nINIT_CONF is not available or not used, nCONFIG must be pulled to VCC either directly or through a 1-k3/4 resistor.

FLEX 8000 Device Configuration
FLEX 8000 devices differ from ACEX 1K, APEX 20K, FLEX 10K, and FLEX 6000 devices in that they have internal oscillators that can provide a DCLK signal to the configuration device. The configuration device sends configuration data out as a serial bitstream on the DATA output pin. This data is routed into the FLEX 8000 device via the DATA0 input pin. The EPC1, EPC1441, EPC1213, EPC1064, and EPC1064V configuration devices support this type of configuration.

Configuration Devices for ACEX, APEX, FLEX & Mercury Devices Data Sheet
EPC1 and EPC1441 devices can replace the EPC1213, EPC1064, and EPC1064V configuration devices. The EPC1 or EPC1441 device automatically emulates the EPC1213, EPC1064, or EPC1064V when it is programmed with the appropriate POF. When the EPC1 or EPC1441 device is programmed with an EPC1213, EPC1064, or EPC1064V POF, the FLEX 8000 device drives the EPC1 or EPC1441 device's OE pin high and clocks the EPC1 or EPC1441 device. One EPC1 device can store more configuration data than the EPC1064, EPC1064V, EPC1213, or EPC1441 device. Therefore, designers can use one type of configuration device for all FLEX devices. In addition, a single EPC1 or EPC1441 device can configure any FLEX 8000 device. For multi-device configuration of FLEX 8000 devices, the nCASC and nCS pins provide handshaking between multiple configuration devices, allowing several cascaded EPC1 or EPC1213 devices to serially configure multiple FLEX 8000 devices. The EPC1441, EPC1064, and EPC1064V do not support data cascading. Figure 7 shows a FLEX 8000 device configured with a single EPC1, EPC1441, EPC1213, EPC1064, or EPC1064V configuration device.

Description
Output
Serial data output. The DATA pin is tri-stated before configuration when the nCS pin is high and after the configuration device finishes sending its configuration data. This operation is independent of the device's position in the cascade chain. DCLK is a clock input when using EPC1, EPC1213, EPC1064, and EPC1064V configuration devices. Rising edges on DCLK increment the internal address counter and present the next bit of data to the DATA pin. The counter is incremented only if the OE input is held high, the nCS input is held low, and all configuration data has not been transferred to the target device. Output enable (active high) and reset (active low). A low logic level resets the address counter. A high logic level enables DATA and permits the address counter to count. Chip-select input (active low). A low input allows DCLK to increment the address counter and enables DATA. Cascade-select output (active low). This output goes low when the address counter has reached its maximum value. The nCASC output is usually connected to the nCS input of the next device in a configuration chain, so the next DCLK clocks data out of the next device. Power pin.

Power & Operation
This section describes Power-On Reset (POR) delay, error detection, and 3.3-V and 5.0-V operation of Altera configuration devices.
Power-On Reset
During initial power-up, a POR delay occurs to permit voltage levels to stabilize. When configuring an ACEX 1K, APEX 20K, FLEX 10K, FLEX 6000, or Mercury device with an EPC2, EPC1, or EPC1441 device, the POR delay occurs inside the configuration device, and the POR delay is a maximum of 100 ms. When configuring a FLEX 8000 device with an EPC1213, EPC1064, or EPC1064V device, the POR delay occurs inside the FLEX 8000 device, and the POR delay is typically 100 ms, with a maximum of 200 ms.
Error Detection Circuitry
The EPC2, EPC1, and EPC1441 configuration devices have built-in error detection circuitry for configuring ACEX 1K, APEX 20K, FLEX 10K, FLEX 6000, and Mercury devices only. Built-in error-detection circuitry uses the nCS pin of the configuration device, which monitors the CONF_DONE pin on the ACEX 1K, APEX 20K, FLEX 10K, FLEX 6000, or Mercury device. An error condition occurs if the CONF_DONE pin does not go high after all the configuration data has been sent, or if the CONF_DONE pin goes high before the configuration device has completed sending configuration data. When an error condition occurs, the configuration device drives its OE pin low, which drives the ACEX 1K, APEX 20K, FLEX 10K, FLEX 6000, or Mercury device's nSTATUS pin low, indicating an error. After an error, configuration automatically restarts if the Auto-Restart Configuration on Frame Error option is turned on in the Global Project Device Options dialog box (Assign menu) in the MAX+PLUS II software. For APEX 20K and Mercury devices, the Quartus software provides a similar option. In addition, if the ACEX 1K, APEX 20K, FLEX 10K, FLEX 6000, or Mercury device detects a cyclic redundancy code (CRC) error in the received data, it may also flag the error by driving nSTATUS low. This low signal on nSTATUS resets the configuration device, allowing reconfiguration. CRC checking is performed when configuring all ACEX 1K, APEX 20K, FLEX 10K, FLEX 6000, and Mercury devices.

3.3-V or 5.0-V Operation
EPC2, EPC1, and EPC1441 devices can configure 5.0-V, 3.3-V, or 2.5-V devices. For each configuration device, an option must be set for 5.0-V or 3.3-V operation. For EPC1 and EPC1441 configuration devices, the Use Low-Voltage Configuration EPROM option in the Global Project Device Options dialog box (Assign menu) in the MAX+PLUS II software sets this parameter. (For APEX 20K and Mercury devices, the Quartus software provides a similar option.) For EPC2 devices, this option is set externally by the VCCSEL pin. In addition, the EPC2 device has an externally controlled option, set by the VPPSEL pin, to adjust the programming voltage to 5.0 V or 3.3 V. The functions of the VCCSEL and VPPSEL pins are described below.
s
VCCSEL pin--For EPC2 configuration devices, 5.0-V or 3.3-V operation is controlled by the VCCSEL option pin. The device functions in 5.0-V mode when VCCSEL is connected to GND; the device functions in 3.3-V mode when VCCSEL is connected to VCC. VPPSEL pin--The EPC2 VPP programming power pin is normally tied to VCC. For EPC2 devices operating with a 3.3-V supply, it is possible to improve EPC2 in-system programming times by providing VPP with a 5.0-V supply. For all other devices, VPP must be tied to VCC. The EPC2 device's VPPSEL pin must be set in accordance with the EPC2 VPP pin. If the VPP pin is supplied by a 5.0-V supply, VPPSEL must be connected to GND; if the VPP pin is supplied by a 3.3-V power supply, VPPSEL must be connected to VCC.

Altera Corporation
Configuration Devices for ACEX, APEX, FLEX & Mercury Devices Data Sheet
For EPC1 and EPC1441 configuration devices, 3.3-V or 5.0-V operation is controlled by a programming bit in the POF. The programming bit value is determined by the core supply voltage of the targeted device during design compilation with the MAX+PLUS II software. For example, EPC1 devices are programmed automatically to operate in 3.3-V mode when configuring FLEX 10KA devices, which have a VCC voltage of 3.3 V. In this example, the EPC1 device's VCC pin is connected to a 3.3-V power supply. Designers may choose to set the configuration device for low voltage when using the MultiVoltTM feature, which allows an ACEX, APEX, FLEX, or Mercury device to bridge between systems operating with different voltages. When compiling for 3.3-V FLEX 6000 devices, set the configuration device for low-voltage operation. To set the EPC1 and EPC1441 configuration devices for low-voltage operation, turn on the Low-Voltage I/O option in the Global Project Device Options dialog box (Assign menu) in the MAX+PLUS II software.
Configuration Chain with Multiple Voltage Levels
An EPC2 or EPC1 device can configure a device chain with multiple voltage levels. All 3.3-V and 2.5-V ACEX, APEX, FLEX, and Mercury devices can be driven by higher-voltage signals. When configuring a mixed-voltage device chain, the ACEX, APEX, FLEX and Mercury devices' VCCINT and VCCIO pins may be connected to 2.5 V, 3.3 V, or 5.0 V, depending upon the device. The configuration device may be powered at 3.3 V or 5.0 V. If an EPC1, EPC1441, EPC1213, EPC1064, or EPC1064V configuration device is powered at 3.3 V, the nSTATUS and CONF_DONE pull-up resistors must be connected to 3.3 V. If these configuration devices are powered at 5.0 V, the nSTATUS and CONF_DONE pull-up resistors must be connected to 3.3 V or 5.0 V. At 3.3-V operation, all EPC2 inputs are 5.0-V tolerant, except DATA, DCLK, and nCASC. The DATA, DCLK, and nCEO pins are used only to interface between the EPC2 and the ACEX 1K, APEX 20K, FLEX 10K, FLEX 6000, or Mercury device it is configuring. The voltage tolerances of all EPC2 pins at 5.0 V and 3.3 V are listed in Table 7. Table 7. EPC2 Input & Bidirectional Pin Voltage Tolerance Pin 5.0-V Operation 5.0-V Tolerant

Programming & Configuration File Support
The Quartus and MAX+PLUS II development systems provide programming support for Altera configuration devices. The Quartus and MAX+PLUS II software automatically generates a POF to program each configuration device in a project. In a multi-device project, the software can combine the programming files for multiple ACEX, APEX, FLEX, or Mercury devices into one or more configuration devices. The software allows you to select the appropriate configuration device to most efficiently store the data for each ACEX, APEX, FLEX, and Mercury device. Moreover, when compiling for ACEX 1K, FLEX 10KA, FLEX 10KE, or Mercury devices, the MAX+PLUS II software automatically defaults to generate the EPC1 or EPC1441 POF with the programming bit set for 3.3-V operation. All Altera configuration devices are programmable using Altera programming hardware in conjunction with the Quartus or MAX+PLUS II software. In addition, many manufacturers offer programming hardware that supports other Altera configuration devices.

Configuration Devices for ACEX, APEX, FLEX & Mercury Devices Data Sheet
The EPC2 configuration device can be programmed in-system through its industry-standard 4-pin JTAG interface. ISP capability in the EPC2 provides ease in prototyping and updating ACEX, APEX, FLEX, and Mercury device functionality. The EPC2 configuration device can be programmed in-system via test equipment using SVF Files, Jam STAPL Files (.jam), or Jam STAPL Byte-Code Files (.jbc), embedded processors using the Jam programming and test language, and the MAX+PLUS II software via the MasterBlaster, ByteBlasterMV, or BitBlaster download cables. When programming multiple EPC2 devices in a JTAG chain, the Quartus and MAX+PLUS II software and other programming methods employ concurrent programming to simultaneously program multiple devices and reduce programming time. EPC2 devices can be programmed and erased up to 100 times. After programming an EPC2 device in-system, ACEX, APEX, FLEX, or Mercury device configuration can be initiated by including the EPC2 JTAG configuration instruction. See Table 8 on page 21.

IEEE Std. 1149.1 (JTAG) Boundary-Scan Testing
The EPC2 provides JTAG BST circuitry that complies with the IEEE Std. 1149.1-1990 specification. JTAG boundary-scan testing can be performed before or after configuration, but not during configuration. The EPC2 device supports the JTAG instructions shown in Table 8. The ISP circuitry in EPC2 devices is compatible with tools that support the IEEE Std. 1532. The IEEE Std. 1532 is a standard developed to allow concurrent ISP between multiple PLD vendors.

BYPASS
Description
Places the 1-bit bypass register between the TDI and TDO pins, which allows the BST data to pass synchronously through a selected device to adjacent devices during normal device operation. Selects the device IDCODE register and places it between TDI and TDO, allowing the device IDCODE to be serially shifted out of TDO. The device IDCODE for the EPC2 is shown below: 0000 0001000000000010 00001101110 1 Selects the USERCODE register and places it between TDI and TDO, allowing the USERCODE to be serially shifted out of TDO. The 32-bit USERCODE is a programmable user-defined pattern. These instructions are used when programming an EPC2 device via JTAG ports with a MasterBlaster, ByteBlaster MV, ByteBlaster, or BitBlaster download cable, or using a Jam STAPL File (.jam), Jam STAPL Byte-Code File (.jbc), or SVF File via an embedded processor. This function allows the user to initiate the APEX or FLEX configuration process by tying nINIT_CONF to the APEX or FLEX device(s) nCONFIG pin(s). After this instruction is updated, the nINIT_CONF pin is driven low. When the Initiate Configuration instruction is cleared, nINIT_CONF is released, which starts the APEX or FLEX device configuration. This instruction is used by the MAX+PLUS II software, Jam STAPL Files, and JBC Files.
