C CAT64LC10/20/40 DEVICE OPERATION The CAT64LC10/20/40 is a 1K/2K/4K-bit nonvolatile memory intended for use with all standard controllers. The CAT64LC10/20/40 is organized in a 64/128/256 x 16 format. All instructions are based on an 8-bit format. There are four 16-bit instructions: READ, WRITE, EWEN, and EWDS. The CAT64LC10/20/40 operates on a single power supply ranging from 2.5V to 6.0V and it has an onchip voltage generator to provide the high voltage needed during a programming operation. Instructions, addresses Figure 2. Sychronous Data Timing and data to be written are clocked into the DI pin on the rising edge of the SK clock. The DO pin is normally in a high impedance state except when outputting data in a READ operation or outputting RDY/BSY status when polled during a WRITE operation. The format for all instructions sent to this device includes a 4-bit start sequence, 1010, a 4-bit op code and an 8bit address field or dummy bits. For a WRITE operation, RESET tRESS SK tDIS DI tCSS CS tCSH tDIH tSKLOW tSKHI DO tRC RDY/BUSY Figure 3. Read Instruction Timing RESET i D SK CS DI DO RDY/BUSY Doc. No. 1021, Rev.

The CAT64LC10/20/40 requires an active LOW CS in order to be selected. Each instruction must be preceded by a HIGH-to-LOW transition of CS before the input of the 4-bit start sequence. Prior to the 4-bit start sequence (1010), the device will ignore inputs of all other logical sequence. Read Upon receiving a READ command and address (clocked into the DI pin), the DO pin will output data one tPD after the falling edge of the 16th clock (the last bit of the address field). The READ operation is not affected by the RESET input. Write After receiving a WRITE op code, address and data, the device goes into the AUTO-Clear cycle and then the Figure 4.

C CAT64LC10/20/40 WRITE cycle. The RDY/BSY pin will output the BUSY status (LOW) one tSV after the rising edge of the 32nd clock (the last data bit) and will stay LOW until the write cycle is complete. Then it will output a logical “1” until the next WRITE cycle. The RDY/BSY output is not affected by the input of CS. An alternative to get RDY/BSY status is from the DO pin. During a write cycle, asserting a LOW input to the CS pin will cause the DO pin to output the RDY/BSY status. Bringing CS HIGH will bring the DO pin back to a high impedance state again. After the device has completed a WRITE cycle, the DO pin will output a logical “1” when the device is deselected. The rising edge of the first “1” input on the DI pin will reset DO back to the high impedance state again. The WRITE operation can be halted anywhere in the operation by the RESET input. If a RESET pulse occurs during a WRITE operation, the device will abort the operation and output a READY status. NOTE: Data may be corrupted if a RESET occurs while the device is BUSY. If the reset occurs before the BUSY period, no writing will be initiated. However, if RESET occurs after the BUSY period, new data will have been written over the old data. Figure 6.

When RESET is set to HIGH while the WRITE instruction is being entered, the device will not execute the WRITE instruction and will keep DO in HighZ condition. When RESET is set to HIGH, while the device is in a clear/write cycle, the device will abort the operation and will display READY status on the RDY/BSY pin and on the DO pin if CS is low. The RESET input affects only the WRITE and WRITE ALL operations. It does not reset any other operations such as READ, EWEN and EWDS. Figure 8. EWDS Instruction Timing RESET ERASE/WRITE ENABLE and DISABLE The CAT64LC10/20/40 powers up in the erase/write disabled state. After power-up or while the device is in an erase/write disabled state, any write operation must be preceded by an execution of the EWEN instruction. Once enabled, the device will stay enabled until an EWDS has been executed or a power-down has occured. The EWDS is used to prevent any inadvertent overwriting of the data. The EWEN and EWDS instructions have no affect on the READ operation and are not affected by the RESET input. SK CS DI 1 0 DO RDY/BUSY i D c s i t n o 1 0 0 0 0 0 HIGH-Z HIGH u n d e a P ts r 9 Doc.
