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.

100 kHz for V

<2.5V

Features:

• Single supply with operation down to 1.8V

• Low-power CMOS technology:

- 1 mA active current, typical

- 1

μA

standby current (max.) (I-temp)

• Organized as a single block of 4K bytes (32 Kbit)

• 2-wire serial interface bus, I

C™ compatible

• Cascadable for up to eight devices

• Schmitt Trigger inputs for noise suppression

• Output slope control to eliminate ground bounce

• 100 kHz (<2.5V) and 400 kHz (≥2.5V)

compatibility

• Self-timed write cycle (including auto-erase)

• Page write buffer for up to 32 bytes

• Hardware write-protect for entire memory

• Can be operated as a serial ROM

• Factory programming (QTP) available

• ESD protection > 4,000V

• 1,000,000 erase/write cycles

• Data retention > 200 years

• 8-lead PDIP, SOIC, TSSOP, DFN and MSOP

packages

• Pb-free finish available

• Available temperature ranges:

- Industrial (I):

-40°C to +85°C

- Automotive (E): -40°C to +125°C
