A93C46
THREE-WIRE SERIAL EEPROM 1K (128 X 8 OR 64 X 16)
DESCRIPTION
The A93C46 provides 1024 bits of serial electrically erasable programmable read only memory (EEPROM) organized as 64 words of 16 bits each, when the ORG pin is connected to VCC and 128 words of 8 bits each when it is tied to ground. The A93C46 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 out serially on the data output pin DO. The WRITE cycle is completely self-timed and no separate erase cycle is required before write.
