Description:

The Microchip Technology Inc. 24AA256/24LC256/

24FC256 (24XX256*) is a 32K x 8 (256 Kbit) Serial

Electrically Erasable PROM, capable of operation

across a broad voltage range (1.7V to 5.5V). It has

been developed for advanced, low-power applications

such as personal communications or data acquisition.

This device also has a page write capability of up to 64

bytes of data. This device is capable of both random

and sequential reads up to the 256K boundary.

Functional address lines allow up to eight devices on

the same bus, for up to 2 Mbit address space. This

device is available in the standard 8-pin plastic DIP,

SOIC, TSSOP, MSOP and DFN packages.

Note 1: 100 kHz for VCC < 2.5V.

2: 400 kHz for VCC < 2.5V.

Features:

• Single Supply with Operation Down to 1.7V for

24AA256 and 24FC256 Devices, 2.5V for

24LC256 Devices

• Low-Power CMOS Technology:

- Active current 400 uA, typical

- Standby current 100 nA, typical

• 2-Wire Serial Interface, I²C^™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.
