NM93C46A 1K-Bit Serial CMOS EEPROM MICROWIRETM Synchronous Bus February 2000 NM93C46A 1K-Bit Serial CMOS EEPROM MICROWIRE Synchronous Bus NM93C46A is a 1024-bit CMOS non-volatile EEPROM organized as 64 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 compatible 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 16-bit format is selected. There are 7 instructions implemented on the NM93C46A 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 NM93C46A offer very low standby current making them suitable for low power applications.
