Description:
The Microchip Technology Inc. 24AA16/24LC16B
(24XX16*) is a 16 Kbit 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 1.7V with standby
and active currents of only 1 μA and 1 mA,
respectively. The 24XX16 also has a page write
capability for up to 16 bytes of data. The 24XX16 is
available in the standard 8-pin PDIP, surface mount
SOIC, TSSOP, 2x3 DFN, 2x3 TDFN and MSOP pack-
ages, and is also available in the 5-lead SOT-23 pack-
age.
