FEATURES

DESCRIPTION

• Industry-standard Microwire Interface

— Non-volatile data storage

The IS93C46A is a low-cost 1kb non-volatile,

ISSI serial EEPROM. It is fabricated using an

— Low voltage operation:

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.

Vcc = 2.5V to 5.5V

— Full TTL compatible inputs and outputs

— Auto increment for efficient data dump

• User Configured Memory Organization

— By 16-bit or by 8-bit

• Hardware and software write protection

— Defaults to write-disabled state at power-up

— Software instructions for write-enable/disable

• Enhanced low voltage CMOS E²PROM

technology

• Versatile, easy-to-use Interface

— Self-timed programming cycle

— Automatic erase-before-write

— Programming status indicator

— Word and chip erasable

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.

— Chip select enables power savings

• Durable and reliable

— 40-year data retention after 1M write cycles

— 1 million write cycles

— Unlimited read cycles

— Schmitt-trigger inputs
