EEPROM ARRAY

(8 x 256 x 8)

The Microchip Technology Inc. 24LC174 is a cascad-

able 16K bit Electrically Erasable PROM. The device is

organized as eight blocks of 256 x 8-bit memory with a

2-wire serial interface and provides a specially

addressed OTP (one-time programmable) 16 byte

security block. Low voltage design permits operation

down to 2.5 volts with standby and active currents of

only 5 µA and 1 mA respectively. The 24LC174 also

has a page-write capability for up to 16 bytes of data.

The 24LC174 is available in the standard 8-pin DIP and

8-lead surface mount SOIC packages.

The three select pins, A0, A1, and A2, function as chip

select inputs and allow up to eight devices to share a

common bus, for up to 128K bits total system

EEPROM.
