DESCRIPTION
The IS93C46A is a low-cost 1kb non-volatile,
ISSI
serial EEPROM. It is fabricated using an
enhanced CMOS design and process. The
IS93C46A contains power-efficient read/write
memory, and organization of 128 bytes of 8 bits
or 64 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 IS93C46A is fully backward
compatible with IS93C46.
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 device is 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 the 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 device can output any
number of consecutive bytes/words using a single
READ instruction.
