NM93CS66 (MICROWIRE Bus Interface) 4096-Bit Serial EEPROM with Data Protect and Sequential Read
NM93CS66 (MICROWIRETM Bus Interface) 4096-Bit Serial EEPROM with Data Protect and Sequential Read

The NM93CS66 devices are 4096 bits of CMOS non-volatile electrically erasable memory divided into 256 16-bit registers. Selected registers can be protected against data modification by programming the Protect Register with the address of the first register to be protected against data modification (all registers greater than, or equal to, the selected address are then protected from further change). Additionally, this address can be "locked" into the device, making all future attempts to change data impossible. These devices are fabricated using Fairchild Semiconductor floating-gate CMOS process for high reliability, high endurance and low power consumption. The NM93CS66 is offered in both SO and TSSOP packages for small space considerations. The EEPROM interfacing is MICROWIRE compatible providing simple interfacing to standard microcontrollers and microprocessors. There are a total of 10 instructions, 5 which operate on the EEPROM memory, and 5 which operate on the Protect Register. The memory instructions are READ, WRITE, WRITE ALL, WRITE ENABLE, and WRITE DISABLE. The Protect register instructions are PRREAD, PRWRITE, PRENABLE, PRCLEAR, and PRDISABLE.
