com   A93C66 THREE-WIRE SERIAL EEPROM 4K (512 X 8 OR 256 X 16) DESCRIPTION FEATURES The A93C66 provides 4096 bits of serial electrically erasable programmable read only memory (EEPROM) organized as 256 words of 16 bits each, when the ORG pin is connected to VCC and 512 words of 8 bits each when it is tied to ground.
The A93C66 is enabled through the Chip Select pin (CS), and accessed via a 3-wire serial interface consisting of Data Input (DI), Data Output (DO), and Shift Clock (SK).
Upon receiving a Read instruction at DI, the address is decoded and the data is clocked  Three-wire Serial Interface  VCC = 1.
8V to 5.
5V  Sequential Read Operation  2 MHz Clock Rate (5V) Compatibility  Self-timed Write Cycle (5 ms max)  1 Million Write Cycles guaranteed  Data Retention > 100 Years  Available in SOP8 and TSSOP8 Package    ORDERING INFORMATION out serially on the data output pin DO.
The WRITE cycle is completely self-timed and no separate erase cycle is required before write.
The Write cycle is only Package Type Part Number A93C66M8R enabled when it is in the Erase/Write Enable state.
When CS is brought “high” following the initiation of a write cycle, the DO pin outputs the Ready/Busy status.
