General Description
The
NM93C06L C46L C56L C66L
devices
are
256 1024 2048 4096 bits respectively of non-volatile
electrically erasable memory divided into 16 64 128 256 x
16-bit registers (addresses) The NM93CxxL Family func-
tions in an extended voltage operating range requires only
a single power supply and is fabricated using National Semi-
conductor鈥檚 floating gate CMOS technology for high reliabili-
ty high endurance and low power consumption These de-
vices are available in both SO and TSSOP packages for
small space considerations
The EEPROM Interfacing is MICROWIRE compatible for
simple interface to standard microcontrollers and micro-
processors There are 7 instructions that control these de-
vices Read Erase Write Enable Erase Erase All Write
Write All and Erase Write Disable The ready busy status
is available on the DO pin during programming
