DESCRIPTION

The Microchip Technology Inc. 24C01C is a 1K bit

Serial Electrically Erasable PROM with a voltage range

of 4.5V to 5.5V. The device is organized as a single

block of 128 x 8-bit memory with a 2-wire serial inter-

face. Low current design permits operation with typical

standby and active currents of only 10

µA and 1 mA

respectively. The device has a page-write capability for

up to 16 bytes of data and has fast write cycle times of

only 1 mS for both byte and page writes. Functional

address lines allow the connection of up to eight

24C01C devices on the same bus for up to 8K bits of

contiguous EEPROM memory. The device is available

in the standard 8-pin PDIP, 8-pin SOIC (150 mil), and

TSSOP packages.
