General Description
The AM93LC56 is the 2048-bit non-volatile serial EEPROM. It is manufactured by using ATCs advanced CMOS EEPROM technology. The AM93LC56 provides efficient non-volatile read/write memory arranged as 128 words of 16 bits each when the ORG Pin is connected to VCC and 256 words of 8 bits each when it is tied to ground. The instruction set includes read, write, and write enable/disable functions. The data out pin (DO) indicates the status of the device during the self-timed non-volatile programming cycle.
