DESCRIPTION

SDA

The Microchip Technology Inc. 24LC01B and 24LC02B

are 1K bit and 2K bit Electrically Erasable PROMs. The

devices are organized as a single block of 128 x 8 bit or

256 x 8 bit memory with a two wire serial interface. Low

voltage design permits operation down to 2.5 volts with

a standby and active currents of only 5 µA and 1 mA

respectively. The 24LC01B and 24LC02B also have

page-write capability for up to 8 bytes of data. The

24LC01B and 24LC02B are available in the standard

8-pin DIP and an 8-pin surface mount SOIC package.

The SOT-23 and TSSOP packages are available for the

24LC01B.

* Available for 24LC01B only
