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.
