DESCRIPTION
The IS93C56A/66A are 2kb/4kb non-volatile,
ISSI
serial EEPROMs. They are fabricated using
an enhanced CMOS design and process. The
IS93C56A/66A contain power-efficient read/write
memory, and organization of either 256/512 bytes
of 8 bits or 128/256 words of 16 bits. When the
ORG pin is connected to Vcc or left unconnected,
x16 is selected; when it is connected to ground,
x8 is selected. The IS93C56A/66A are fully
backward compatible with IS93C56/66.
An instruction set defines the operation of the
devices, including read, write, and mode-enable
functions. To protect against inadvertent data
modification, all erase and write instructions are
accepted only while the devices are write-enabled.
A selected x8 byte or x16 word can be modified
with a single WRITE or ERASE instruction.
Additionally, the two instructions WRITE ALL or
ERASE ALL can program an entire array. Once a
device begins its self-timed program procedure,
the data out pin (Dout) can indicate the READY/
BUSY
status by raising chip select (CS). The self-
timed write cycle includes an automatic erase-
before-write capability. The devices can output
any number of consecutive bytes/words using a
single READ instruction.
