NM93CS06 CS46 CS56 CS66
(MICROWIRETM Bus Interface) 256- 1024- 2048- 4096-Bit
Serial EEPROM with Data Protect and Sequential Read
General Description
The NM93CS06 CS46 CS56 CS66 devices are 256
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
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
Features
Y Write protection in a user defined section of memory
Y Sequential register read
Y Typical active current of 400 mA and standby current of
25 mA
Y No erase required before write
Y Reliable CMOS floating gate technology
Y MICROWIRE compatible serial I O
Y Self timed write cycle
Y Device status during programming mode
Y 40 year data retention
Y Endurance 106 data changes
Y 4 5V to 5 5V operation in all modes of operation
Y Packages available 8-pin SO 8-pin DIP
