null General Description

The AM93LC56 is the 2048-bit non-volatile serial
EEPROM. It is manufactured by using ATC's
advanced CMOS EEPROM technology. The
AM93LC56 provides efficient non-volatile read/write
memory arranged as 128 words of 16 bits each
when the ORG Pin is connected to VCC and 256
words of 8 bits each when it is tied to ground. The
instruction set includes read, write, and write
enable/disable functions. The data out pin (DO)
indicates the status of the device during the
self-timed non-volatile programming cycle.
The self-timed write cycle includes an automatic
erase-before-write capability. Only when the chip is
in the WRITE ENABLE state and proper VCC
operation range is the WRITE instruction accepted
and thus to protect against inadvertent writes. Data
is written in 16 bits per write instruction into the
selected register. If Chip Select (CS) is brought
HIGH after initiation of the write cycle, the Data
Output (DO) pin will indicate the READY/BUSY
status of the chip.
The AM93LC56 is available in space-saving 8-lead
PDIP, 8-lead SOP and rotated 8-lead SOP package.
