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

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.

100 kHz for V

<2.5V

Features:

• Single supply with operation down to 1.7V for

24AA32A devices, 2.5V for 24LC32A devices

• Low-power CMOS technology:

- Active current 1 mA, typical

- Standby current 1

μA,

typical

• 2-wire serial interface, I

C™ compatible

• Cascadable up to eight devices

• Schmitt Trigger inputs for noise suppression

• Output slope control to eliminate ground bounce

• 100 kHz and 400 kHz clock compatibility

• Page write time 5 ms max.

• Self-timed erase/write cycle

• 32-byte page write buffer

• Hardware write-protect

• ESD protection > 4,000V

• More than 1 million erase/write cycles

• Data retention > 200 years

• Factory programming available

• Packages include 8-lead PDIP, SOIC, TSSOP,

MSOP and DFN

• Pb-free and RoHS compliant

• Temperature ranges:

- Industrial (I):

-40°C to +85°C

- Automotive (E): -40°C to +125°C
