General Description
The AM93LC86 is the 16384-bit non-volatile serial
EEPROM. The AM93LC86 provides efficient
non-volatile read/write memory arranged as 1024
words of 16 bits each when the ORG Pin is
connected to VCC and 2048 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 read/busy status of the chip.
The AM93LC86 is available in space-saving 8-lead
PDIP, SOP and TSSOP packages.
