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 Semi-
conductor鈥檚 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 MI-
CROWIRE compatible for simple interface to standard mi-
crocontrollers and microprocessors There are 7 instruc-
tions 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
