NM93C86A 16K-Bit Serial CMOS EEPROM (MICROWIRETM Synchronous Bus) February 2000 NM93C86A 16K-Bit Serial CMOS EEPROM (MICROWIRE™ Synchronous Bus) General Description NM93C86A is a 16,384-bit CMOS non-volatile EEPROM organized as 1024 x 16-bit array. This device 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 patible to many of standard Microcontrollers and Microprocessors. This device 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 16bit format is selected. There are 7 instructions implemented on the NM93C86A for various Read, Write, Erase, and Write Enable/ Disable operations. This device is fabricated using Fairchild Semiconductor floating-gate CMOS process for high reliability, high endurance and low power consumption. “LZ” and “L” versions of NM93C86A 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.
