FEATURES

OVERVIEW

• State-of-the-artarchitecture

— Non-volatile data storage

The IS93C46-3 is a low cost 1,024-bit, non-volatile, serial

E²PROM. It is fabricated using ISSI’s advanced CMOS

E²PROM technology. The IS93C46-3 provides efficient

non-volatile read/write memory arranged as 64 registers

of 16 bits each. Seven 9-bit instructions control the

operation of the device, which includes read, write, and

mode enable functions. The data out pin (DOUT) indicates

the status of the device during in the self-timed non-

volatile programming cycle.

— Low voltage operation:

3.0V (Vcc = 2.7V to 6.0V)

— Full TTL compatible inputs and outputs

— Auto increment for efficient data dump

• Low voltage read operation

— Down to 2.7V

• Hardware and software write protection

— Defaults to write-disabled state at power-up

— Softwareinstructionsforwrite-enable/disable

• Advanced low voltage CMOS E²PROM

technology

• Versatile, easy-to-useInterface

— Self-timedprogrammingcycle

— Automaticerase-before-write

— Programming status indicator

— Word and chip erasable

The self-timed write cycle includes an automatic erase-

before-write capability. To protect against inadvertent

writes, the WRITE instruction is accepted only while the

chip is in the write enabled state. 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 (D^OUT) pin will indicate the READY/

BUSY status of the chip.

APPLICATIONS

The IS93C46-3 is ideal for high-volume applications

requiring low power and low density storage. This device

uses a low cost, space saving 8-pin package. Candidate

applications include robotics, alarm devices, electronic

locks, meters and instrumentation settings.

— Stop SK anytime for power savings

• Durable and reliable

— 10-year data retention after 100K write cycles

— 100,000 write cycles

— Unlimited read cycles
