Description
The Microchip Technology Inc. 24AA02/24LC02B
(24XX02*) is a 2 Kbit Electrically Erasable PROM. The
device is organized as one block of 256 x 8-bit memory
with a 2-wire serial interface. Low-voltage design
permits operation down to 1.8V, with standby and
active currents of only 1
碌A
and 1 mA, respectively.
The 24XX02 also has a page write capability for up to
8 bytes of data. The 24XX02 is available in the
standard 8-pin PDIP, surface mount SOIC, TSSOP and
MSOP packages and is also available in the 5-lead
SOT-23 package.
