Serial EEPROM

Description:

The Microchip Technology Inc. 24AA32A/24LC32A

(24XX32A*) is a 32 Kbit Electrically Erasable PROM.

The device is organized as a single block of 4K 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 A and 1 mA,

respectively. It has been developed for advanced, low-

power applications such as personal communications

or data acquisition. The 24XX32A also has a page write

capability for up to 32 bytes of data. Functional address

lines allow up to eight devices on the same bus, for up

to 256 Kbits address space. The 24XX32A is available

in the standard 8-pin PDIP, surface mount SOIC, SOIJ,

TSSOP, DFN, TDFN and MSOP packages. The

24XX32A is also available in the 5-lead SOT-23 and

Chip Scale packages.
