Description:
The Microchip Technology Inc. 24AA01H/24LC01BH
(24XX01H*) is a 1 Kbit Electrically Erasable PROM.
The device is organized as one block of 128 x 8-bit
memory with a 2-wire serial interface. Low-voltage
design permits operation down to 1.7V with standby
and active currents of only 1 μA and 1 mA, respec-
tively. The 24XX01H also has a page write capability for
up to 8 bytes of data. The 24XX01H is available in the
standard 8-pin PDIP, surface mount SOIC, TSSOP, 2x3
TDFN and MSOP packages, and is also available in
the 5-lead SOT-23 and SC-70 packages.
