NM93C56A

NM93C56A is a 2048-bit CMOS non-volatile EEPROM organized as 128 x 16-bit array. NM93C56A features MICROWIRE interface which is a 4-wire serial bus with chipselect (CS), clock (SK), data input (DI) and data output (DO) signals. This interface is compatible to many of standard Microcontrollers and Microprocessors. NM93C56A offers a pin (ORG), using which, the user can select the format of the data (16-bit or 8-bit). If ORG is tied to GND, then 8-bit format is selected, while if ORG is tied to VCC, then 16-bit format is selected. There are 7 instructions implemented on the NM93C56A for various Read, Write, Erase, and Write Enable/ Disable operations. NM93C56A is fabricated using Fairchild Semiconductor floating-gate CMOS process for high reliability, high endurance and low power consumption.

"LZ" and "L" versions of NM93C56A offer very low standby current making them suitable for low power applications. This device is offered in both SO and TSSOP packages for small space considerations.
