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 1.8V, with standby
and active currents of only 1
μA
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,
TSSOP, 2x3 DFN and MSOP packages.
