DESCRIPTION
The Microchip Technology Inc. 24LC16B is a 16K bit
Electrically Erasable PROM. The device is organized
as eight blocks of 256 x 8 bit memory with a 2-wire
serial interface. Low voltage design permits operation
down to 2.5 volts with standby and active currents of
only 5
µA
and 1 mA respectively. The 24LC16B also
has a page-write capability for up to 16 bytes of data.
The 24LC16B is available in the standard 8-pin DIP and
both 8-lead and 14-lead surface mount SOIC pack-
ages.
