They are accessed through a Serial Data input (D) and Serial Data output (Q) using the MICROWIRE bus protocol. Figure 1. Logic diagram VCC D C M93Cx6 S ORG Q VSS AI01928 Table 2. Signal names Function Chip Select Serial Data input Serial Data output Serial Clock Organisation Select Supply voltage Ground Input Input Output Input Input Direction Signal name S D Q C ORG VCC VSS The memory array organization may be divided into either bytes (x8) or words (x16) which may be selected by a signal applied on Organization Select (ORG). The bit, byte and word sizes of the memories are as shown in Table 3. 6/37 Doc ID 4997 Rev 10 M93C86, M93C76, M93C66, M93C56, M93C46 Table 3.

Table 4. Instruction set for the M93Cx6 Description Read Data from Memory Write Data to Memory Write Enable Write Disable Erase Byte or Word Erase All Memory Write All Memory with same Data Byte or Word Data Byte or Word Byte or Word Instruction READ WRITE WEN WDS ERASE ERAL WRAL A Read Data from Memory (READ) instruction loads the address of the first byte or word to be read in an internal address register. The data at this address is then clocked out serially. The address register is automatically incremented after the data is output and, if Chip Select Input (S) is held High, the M93Cx6 can output a sequential stream of data bytes or words. In this way, the memory can be read as a data stream from eight to 16384 bits long (in the case of the M93C86), or continuously (the address counter automatically rolls over to 00h when the highest address is reached). Programming is internally self-timed (the external clock signal on Serial Clock (C) may be stopped or left running after the start of a Write cycle) and does not require an Erase cycle prior to the Write instruction. The Write instruction writes 8 or 16 bits at a time into one of the byte or word locations of the M93Cx6. After the start of the programming cycle, a Busy/Ready signal is available on Serial Data Output (Q) when Chip Select Input (S) is driven High. An internal Power-on Data Protection mechanism in the M93Cx6 inhibits the device when the supply is too low. Doc ID 4997 Rev 10 7/37 Description Figure 2.

See Package mechanical data section for package dimensions, and how to identify pin-1. 2. DU = Don't Use. The DU (do not use) pin does not contribute to the normal operation of the device. It is reserved for use by STMicroelectronics during test sequences. The pin may be left unconnected or may be connected to VCC or VSS. 8/37 Doc ID 4997 Rev 10 M93C86, M93C76, M93C66, M93C56, M93C46 Connecting to the serial bus 2 Connecting to the serial bus Figure 3 shows an example of three memory devices connected to an MCU, on a serial bus. Only one device is selected at a time, so only one device drives the Serial Data output (Q) line at a time, the other devices are high impedance. The pull-down resistor R (represented in Figure 3) ensures that no device is selected if the bus master leaves the S line in the high impedance state. In applications where the bus master may be in a state where all inputs/outputs are high impedance at the same time (for example, if the bus master is reset during the transmission of an instruction), the clock line (C) must be connected to an external pull-down resistor so that, if all inputs/outputs become high impedance, the C line is pulled low (while the S line is pulled low): this ensures that C does not become high at the same time as S goes low, and so, that the tSLCH requirement is met. The typical value of R is 100 k . Figure 3.

In order to secure a stable DC supply voltage, it is recommended to decouple the VCC line with a suitable capacitor (usually of the order of 10 nF to 100 nF) close to the VCC/VSS package pins. This voltage must remain stable and valid until the end of the transmission of the instruction and, for a Write instruction, until the completion of the internal write cycle (tW). 3.1.2 Power-up conditions When the power supply is turned on, VCC rises from VSS to VCC. During this time, the Chip Select (S) line is not allowed to float and should be driven to VSS, it is therefore recommended to connect the S line to VSS via a suitable pull-down resistor. The VCC rise time must not vary faster than 1 V/s. 3.1.3 Power-up and device reset In order to prevent inadvertent Write operations during power-up, a power on reset (POR) circuit is included. At power-up (continuous rise of VCC), the device does not respond to any instruction until VCC has reached the power on reset threshold voltage (this threshold is lower than the minimum VCC operating voltage defined in Table 9, Table 10 and Table 11). When VCC passes the POR threshold, the device is reset and is in the following state: Standby Power mode deselected (assuming that there is a pull-down resistor on the S line) 3.1.4 Power-down At power-down (continuous decrease in VCC), as soon as VCC drops from the normal operating voltage to below the power on reset threshold voltage, the device stops responding to any instruction sent to it. During power-down, the device must be deselected and in the Standby Power mode (that is, there should be no internal Write cycle in progress). 10/37 Doc ID 4997 Rev 10 M93C86, M93C76, M93C66, M93C56, M93C46 Memory organization 4 Memory organization The M93Cx6 memory is organized either as bytes (x8) or as words (x16). If Organization Select (ORG) is left unconnected (or connected to VCC) the x16 organization is selected; when Organization Select (ORG) is connected to Ground (VSS) the x8 organization is selected. When the M93Cx6 is in Standby mode, Organization Select (ORG) should be set either to VSS or VCC for minimum power consumption. Any voltage between VSS and VCC applied to Organization Select (ORG) may increase the Standby current. Doc ID 4997 Rev 10 11/37 Instructions M93C86, M93C76, M93C66, M93C56, M93C46 5 Instructions The instruction set of the M93Cx6 devices contains seven instructions, as summarized in Table 5. to Table 7.. Each instruction consists of the following parts, as shown in Figure 4.: Each instruction is preceded by a rising edge on Chip Select Input (S) with Serial Clock (C) being held low. A start bit, which is the first `1' read on Serial Data Input (D) during the rising edge of Serial Clock (C). Two op-code bits, read on Serial Data Input (D) during the rising edge of Serial Clock (C). (Some instructions also use the first two bits of the address to define the op-code). The address bits of the byte or word that is to be accessed. For the M93C46, the address is made up of 6 bits for the x16 organization or 7 bits for the x8 organization (see Table 5.). For the M93C56 and M93C66, the address is made up of 8 bits for the x16 organization or 9 bits for the x8 organization (see Table 6.). For the M93C76 and M93C86, the address is made up of 10 bits for the x16 organization or 11 bits for the x8 organization (see Table 7.). The M93Cx6 devices are fabricated in CMOS technology and are therefore able to run as slow as 0 Hz (static input signals) or as fast as the maximum ratings specified in Table 20. to Table 23..

Doc ID 4997 Rev 10 13/37 Instructions M93C86, M93C76, M93C66, M93C56, M93C46 5.1 Read Data from Memory The Read Data from Memory (READ) instruction outputs data on Serial Data Output (Q). When the instruction is received, the op-code and address are decoded, and the data from the memory is transferred to an output shift register. A dummy 0 bit is output first, followed by the 8-bit byte or 16-bit word, with the most significant bit first. Output data changes are triggered by the rising edge of Serial Clock (C). The M93Cx6 automatically increments the internal address register and clocks out the next byte (or word) as long as the Chip Select Input (S) is held High. In this case, the dummy 0 bit is not output between bytes (or words) and a continuous stream of data can be read. 5.2 Write Enable and Write Disable The Write Enable (WEN) instruction enables the future execution of erase or write instructions, and the Write Disable (WDS) instruction disables it. When power is first applied, the M93Cx6 initializes itself so that erase and write instructions are disabled. After an Write Enable (WEN) instruction has been executed, erasing and writing remains enabled until an Write Disable (WDS) instruction is executed, or until VCC falls below the power-on reset threshold voltage. To protect the memory contents from accidental corruption, it is advisable to issue the Write Disable (WDS) instruction after every write cycle. The Read Data from Memory (READ) instruction is not affected by the Write Enable (WEN) or Write Disable (WDS) instructions. 14/37 Doc ID 4997 Rev 10 M93C86, M93C76, M93C66, M93C56, M93C46 Figure 4.

For the meanings of An, Xn, Qn and Dn, see Table 5., Table 6. and Table 7.. 5.3 Erase Byte or Word The Erase Byte or Word (ERASE) instruction sets the bits of the addressed memory byte (or word) to 1. Once the address has been correctly decoded, the falling edge of the Chip Select Input (S) starts the self-timed Erase cycle. The completion of the cycle can be detected by monitoring the READY/BUSY line, as described in the READY/BUSY status section. Doc ID 4997 Rev 10 15/37 Instructions M93C86, M93C76, M93C66, M93C56, M93C46 5.4 Write For the Write Data to Memory (WRITE) instruction, 8 or 16 data bits follow the op-code and address bits. These form the byte or word that is to be written. As with the other bits, Serial Data Input (D) is sampled on the rising edge of Serial Clock (C). After the last data bit has been sampled, the Chip Select Input (S) must be taken low before the next rising edge of Serial Clock (C). If Chip Select Input (S) is brought low before or after this specific time frame, the self-timed programming cycle will not be started, and the addressed location will not be programmed. The completion of the cycle can be detected by monitoring the READY/BUSY line, as described later in this document. Once the Write cycle has been started, it is internally self-timed (the external clock signal on Serial Clock (C) may be stopped or left running after the start of a Write cycle). The cycle is automatically preceded by an Erase cycle, so it is unnecessary to execute an explicit erase instruction before a Write Data to Memory (WRITE) instruction. Figure 5.

For the meanings of An and Xn, please see Table 5., Table 6. and Table 7.. 5.5 Erase All The Erase All Memory (ERAL) instruction erases the whole memory (all memory bits are set to 1). The format of the instruction requires that a dummy address be provided. The Erase cycle is conducted in the same way as the Erase instruction (ERASE). The completion of the cycle can be detected by monitoring the READY/BUSY line, as described in the READY/BUSY status section. 16/37 Doc ID 4997 Rev 10 M93C86, M93C76, M93C66, M93C56, M93C46 Instructions 5.6 Write All As with the Erase All Memory (ERAL) instruction, the format of the Write All Memory with same Data (WRAL) instruction requires that a dummy address be provided. As with the Write Data to Memory (WRITE) instruction, the format of the Write All Memory with same Data (WRAL) instruction requires that an 8-bit data byte, or 16-bit data word, be provided. This value is written to all the addresses of the memory device. The completion of the cycle can be detected by monitoring the READY/BUSY line, as described next. Figure 6. WRITE ALL WRAL sequence S CHECK STATUS D 1 0 0 0 1 Xn X0 Dn D0 Q ADDR OP CODE AI00880C DATA IN BUSY READY 1. For the meanings of Xn and Dn, please see Table 5., Table 6. and Table 7.. Doc ID 4997 Rev 10 17/37 READY/BUSY status M93C86, M93C76, M93C66, M93C56, M93C46 6 READY/BUSY status While the Write or Erase cycle is underway, for a WRITE, ERASE, WRAL or ERAL instruction, the Busy signal (Q=0) is returned whenever Chip Select input (S) is driven high. (Please note, though, that there is an initial delay, of tSLSH, before this status information becomes available). In this state, the M93Cx6 ignores any data on the bus. When the Write cycle is completed, and Chip Select Input (S) is driven high, the Ready signal (Q=1) indicates that the M93Cx6 is ready to receive the next instruction. Serial Data Output (Q) remains set to 1 until the Chip Select Input (S) is brought low or until a new start bit is decoded. 7 Initial delivery state The device is delivered with all bits in the memory array set to 1 (each byte contains FFh). 8 Common I/O operation Serial Data Output (Q) and Serial Data Input (D) can be connected together, through a current limiting resistor, to form a common, single-wire data bus. Some precautions must be taken when operating the memory in this way, mostly to prevent a short circuit current from flowing when the last address bit (A0) clashes with the first data bit on Serial Data Output (Q). Please see the application note AN394 for details. 18/37 Doc ID 4997 Rev 10 M93C86, M93C76, M93C66, M93C56, M93C46 Clock pulse counter 9 Clock pulse counter In a noisy environment, the number of pulses received on Serial Clock (C) may be greater than the number delivered by the master (the microcontroller). This can lead to a misalignment of the instruction of one or more bits (as shown in Figure 7.) and may lead to the writing of erroneous data at an erroneous address. To combat this problem, the M93Cx6 has an on-chip counter that counts the clock pulses from the start bit until the falling edge of the Chip Select Input (S). If the number of clock pulses received is not the number expected, the WRITE, ERASE, ERAL or WRAL instruction is aborted, and the contents of the memory are not modified. The number of clock cycles expected for each instruction, and for each member of the M93Cx6 family, are summarized in Table 5. to Table 7.. For example, a Write Data to Memory (WRITE) instruction on the M93C56 (or M93C66) expects 20 clock cycles (for the x8 organization) from the start bit to the falling edge of Chip Select Input (S). That is: 1 Start bit + 2 Op-code bits + 9 Address bits + 8 Data bits Figure 7.
