Description:

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 μA and 400 μA, 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.
