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
interface. 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 capabil-
ity for up to 16 bytes of data and has fast write cycle
times of only 1 ms for both byte and page writes. Func-
tional 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 (3.90 mm), 8-
pin 2x3 DFN, 8-pin MSOP and TSSOP packages.
