DESCRIPTION
The IS93C46B is a low-cost 1kb non-volatile,
ISSI
serial EEPROM. It is fabricated using an
enhanced CMOS design and process. The
IS93C46B contains power-efficient read/write
memory, and organization of 64 words of 16 bits.
The IS93C46B 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 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 words using a single READ
instruction.
