Description

The Microchip Technology Inc. 24LC41A is a dual port 128 x 8 and 512 x 8-bit Electrically Erasable PROM (EEPROM). This device is designed for use in applications requiring storage and serial transmission of configuration and control information. Three modes of operation have been implemented:

? Transmit-only mode for the DDC Monitor Port

? Bidirectional mode for the DDC Monitor Port

? Bidirectional, industry-standard 2-wire bus for the 4K Microcontroller Access Port

Features

? Single supply with operation down to 2.5V

? Completely implements DDC1?/DDC2? interface

for monitor identification, including recovery to

DDC1

? Improved noise immunity

? Separate high speed 2-wire bus for

microcontroller access to 4K-bit Serial EEPROM

? Low-power CMOS technology

? 2 mA active current typical

? 20 μA standby current typical at 5.5V

? Dual 2-wire serial interface bus, I2C? compatible

? Hardware write-protect for Microcontroller Access

Port

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

? Page write buffer for up to 8 bytes (DDC port) or

16 bytes (4K Port)

? 100 kHz (2.5V) and 400 kHz (5V) compatibility

? 1,000,000 erase/write cycles

? Data retention > 40 years

? 8-pin PDIP package

? Available for extended temperature ranges

- Commercial (C): 0°C to +70°C

- Industrial (I): -40°C to +85°C
