Speeds down to 10 ns and power dissipation as low as 10 mA are offered. All speed ranges are specified over the 3.0V to 5.5V range for industrial and commercial temperature ranges. The ATF22LV10C provides a low-voltage and user controlled "zero" power CMOS PLD solution. A user-controlled power-down feature offers "zero" (5 mA typical) standby power. This feature allows the user to manage total system power to meet specific application requirements and enhance reliability, all without sacrificing speed. (The ATF22LV10CZ provides edge-sensing "zero" standby power (10 mA typical), as well as low voltage operation. See the ATF22LV10CZ datasheet.) The ATF22LV10C is capable of operating at supply voltages down to 3.0V. When the power-down pin is active, the device is placed into a zero standby power-down mode. When the power-down pin is not used or active, the device operates in a full power low voltage mode. Pin "keeper" circuits on input and output pins hold pins to their previous logic levels when idle, which eliminate static power consumed by pull-up resistors. The ATF22LV10C macrocell incorporates a variable product term architecture. Each output is allocated from 8 to 16 product terms which allows highly-complex logic functions to be realized. Two additional product terms are included to provide synchronous reset and asynchronous reset. These additional product terms are common to all 10 registers and are automatically cleared upon power-up. Register preload simplifies testing. A security fuse prevents unauthorized copying of programmed fuse patterns.

The ATF22LV10C has 12 inputs and 10 I/O macrocells. Each macrocell can be configured into one of four output configurations: active high/low, registered/combinatorial output.The universal architecture of the ATF22LV10C can be programmed to emulate most 24-pin PAL devices. Unused product terms are automatically disabled by the compiler to decrease power consumption. A security fuse, when programmed, protects the contents of the ATF22LV10C. Eight bytes (64 fuses) of User Signature are accessible to the user for purposes such as storing project name, part number, revision or date. The User Signature is accessible regardless of the state of the security fuse.

This parameter is only sampled and is not 100% tested. 5 Power-up Reset The registers in the ATF22LV10C are designed to reset during power-up. At a point delayed slightly from VCC crossing V RST , all registers will be reset to the low state. The output state will depend on the polarity of the buffer. This feature is critical for state machine initialization. However, due to the asynchronous nature of reset and the uncertainty of how V CC actually rises in the system, the following conditions are required: 1. The VCC rise must be monotonic and start below 0.7V. 2. The clock must remain stable during TPR. 3. After TPR, all input and feedback setup times must be met before driving the clock pin high. Programming/Erasing Programming/erasing is performed using standard PL D pr ogr am mer s. Se e CM O S P LD Pr ogr am min g Hardware & Software Support for information on software/programming. Parameter TPR Description Power-up Reset Time Power-up Reset Voltage Typ 600 Max 1,000 Units ns VRST 2.5 3.0 V Input and I/O Pin-keeper All ATF22V10C family members have internal input and I/O pin-keeper circuits. Therefore, whenever inputs or I/Os are not being driven externally, they will maintain their last driven state. This ensures that all logic array inputs and device outputs are at known states. These are relatively weak active circuits that can be easily overridden by TTLcompatible drivers (see Input and I/O diagrams on page 8). Preload of Register Outputs The ATF22LV10C registers are provided with circuitry to allow loading of each register with either a high or a low. This feature will simplify testing since any state can be forced into the registers to control test sequencing. A JEDEC file with preload is generated when a source file with vectors is compiled. Once downloaded, the JEDEC file preload sequence will be done automatically by most of the approved programmers after the programming. Power-down Mode The ATF22LV10C includes an optional pin controlled power-down feature. When this mode is enabled, the PD pin acts as the power-down pin (Pin 4 on the DIP/SOIC packages and Pin 5 on the PLCC package). When the PD pin is high, the device supply current is reduced to less than 100 mA. During power-down, all output data and internal logic states are latched and held. Therefore, all registered and combinatorial output data remain valid. Any outputs which were in an undetermined state at the onset of power-down will remain at the same state. During powerdown, all input signals except the power-down pin are blocked. Input and I/O hold latches remain active to insure that pins do not float to indeterminate levels, further reducing system power. The power-down pin feature is enabled in the logic design file. Designs using the power-down pin may not use the PD pin logic array input. However, all other PD pin macrocell resources may still be used, including the buried feedback and foldback product term array inputs. PD pin configuration is controlled by the design file, and appears as a separate fuse bit in the JEDEC file. When the power-down feature is not specified in the design file, the IN/PD pin will be configured as a regular logic input. Note: Some programmers list the 22V10 JEDEC compatible 22V10C (no PD used) separately from the non-22V10 JEDEC compatible 22V10CEX (with PD used). Electronic Signature Word There are 64 bits of programmable memory that are always available to the user, even if the device is secured. These bits can be used for user-specific data. Security Fuse Usage A single fuse is provided to prevent unauthorized copying of the ATF22LV10C fuse patterns. Once programmed, fuse verify and preload are inhibited. However, the 64-bit User Signature remains accessible. The security fuse should be programmed last, as its effect is immediate. 6 ATF22LV10C ATF22LV10C Input Diagram VCC 100K INPUT ESD PROTECTION CIRCUIT I/O Diagram VCC OE DATA I/O VCC INPUT 100K 7 Functional Logic Diagram ATF22LV10C *Input not available if the power-down (PD) option is utilized. 8 ATF22LV10C ATF22LV10C ATF22LV10C SUPPLY CURRENT VS.
