NM93C06LZ/C46LZ/C56LZ/C66LZ
256-/1024-/2048-/4096-Bit Serial EEPROM with Zero
Power and Extended Voltage (2.7V to 5.5V)
(MICROWIRE

September 1996
NM93C06LZ/C46LZ/C56LZ/C66LZ 256-/1024-/2048-/4096-Bit Serial EEPROM with Zero Power
and Extended Voltage (2.7V to 5.5V) (MICROWIRE Bus Interface)
General Description
The NM93C06LZ/C46LZ/C56LZ/C66LZ devices are 256/
1024/2048/4096 bits respectively, of CMOS non-volatile
electrically erasable memory divided into 16/64/128/256
16-bit registers. They are fabricated using National Semiconductor’s floating-gate CMOS process for high reliability
and low power consumption. These memory devices are
available in both SO and TSSOP packages for small space
considerations.
The serial interface that operates these EEPROMs is MICROWIRE compatible for simple interface to standard microcontrollers and microprocessors. There are 7 instructions that control these devices: Read, Erase/Write Enable,
Erase, Erase All, Write, Write All, and Erase/Write Disable.
The ready/busy status is available on the DO pin to indicate
the completion of a programming cycle.
