(2)General Description
The Microchip Technology Inc. 24LC08B is a
The device is organized as four blocks of 256x9bit memory with a two wire serial interface. Low voltage
design permits operation down to 2.5 volts with standby and active currents of only 5
A and 1mA respectively. The 24LC08B also has a
The 24L08B is available in the standard
