*24XX16H is used in this document as a generic part
number for the 24AA16H/24LC16BH devices.
Description:
The Microchip Technology Inc. 24AA16H/24LC16BH
(24XX16H*) is an 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 24XX16H also has a page write
capability for up to 16 bytes of data. The 24XX16H 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 package. All
packages are Pb-free and RoHS compliant.
