Description

The Microchip Technology Inc. 24LC09 is an 8 Kbit

Electrically Erasable PROM (EEPROM) designed to

meet the Advanced Communication Riser Special

Interest Group (ACR-SIG). The device is organized as

four blocks of 256 x 8-bit memory that supports the 2-

wire serial interface with a special address: 1011. Low

voltage design permits operation down to 2.5 volts with

typical standby and active currents of only 5 µA and

1 mA, respectively. The 24LC09 also has a page-write

capability for up to 16 bytes of data. The 24LC09 is

available in the standard 8-pin DIP, 8-lead surface

mount SOIC packages.
