NM93CS06/CS46/CS56/CS66
(MICROWIRE
TM
Bus Interface) 256-/1024-/2048-/4096-Bit
Serial EEPROM with Data Protect and Sequential Read
General Description
The
NM93CS06/CS46/CS56/CS66
1024/2048/4096 bits, respectively, of CMOS non-volatile
electrically erasable memory divided into 16/64/128/
256 16-bit registers. Selected registers can be protected
against data modification by programming the Protect Reg-
ister 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 impossi-
ble. These devices are fabricated using National Semicon-
ductor floating-gate CMOS process for high reliability, high
endurance and low power consumption. The NM93CSXX
Family is offered in an SO package for small space consid-
erations.

256/
The EEPROM interfacing is MICROWIRE compatible pro-
viding simple interfacing to standard microcontrollers and
microprocessors. There are a total of 10 instructions, 5
which operate on the EEPROM memory, and 5 which oper-
ate 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.
