BR93LC56FJ-W / BR93LC56RFJ-W / BR93LC56FV-W

The BR93LC56-W series are CMOS serial input / output-type memory circuits (EEPROMs) that can be programmed

electrically. Each is configured of 128 words x 16 bits (2,048 bits), and each word can be accessed individually and data

read from it and written to it. Operation control is performed using five types of commands.

The commands, addresses, and data are input through the DI pin under the control of the CS and SK pins. In a write

operation, the internal status signal (READY or BUSY) can be output from the DO pin.

Applications

VCRs, TVs, printers, car stereos, cordless telephones, short wave radios, programmable DIP switches, and

other battery-powered equipment requiring low voltage and low current

Features

1) 128 words

16 bits EEPROM

2) Operating voltage range

When reading : 2.0 to 5.5V

When writing : 2.7 to 5.5V

3) Low current consumption

Operating (at 5V) : 3mA (Max.)

Standby (at 5V) : 5µA (Max.)

4) Address can be incremented automatically during

read operations.

5) Auto erase and auto complete functions can be used

during write operations.

6) A write instruction inhibit function allows :

- write protection when power supply voltage is low.

- write disable state at power up.

- writing using command codes.

7) Compact packages

8) Display of READY / BUSY status

9) TTL-compatible input / output

10) Rewriting possible up to 100,000 times

11) Data can be stored for ten years without corruption.
