DESCRIPTION
The Microchip Technology Inc. 24LC174 is a cascad-
able 16K bit Electrically Erasable PROM. The device
is organized as 8 blocks of 256 x 8 bit memory with a
two 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
μ
A 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.
