Range

The Microchip Technology Inc. 24AA044 is a 4 Kbit

Serial Electrically Erasable PROM with a voltage

range of 1.7V to 5.5V. The device is organized as two

blocks of 256 x 8-bit memory with a 2-wire serial

interface. Low-current design permits operation with

standby and active currents of only 1 A and 400 A,

respectively. The device has a page write capability for

up to 16 bytes of data. Functional address lines allow

the connection of up to four 24AA044 devices on the

same bus for up to 16K bits of contiguous EEPROM

memory. The device is available in the standard 8-pin

PDIP, 8-pin SOIC (3.90 mm), TSSOP, 2x3 UDFN and

MSOP packages.
