Serial EEPROM
Description:
The Microchip Technology Inc. 24C02C is a 2K bit
Serial Electrically Erasable PROM with a voltage range
of 4.5V to 5.5V. The device is organized as a single
block of 256 x 8-bit memory with a 2-wire serial
interface. Low-current design permits operation with
max. standby and active currents of only 5 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.
Functional address lines allow the connection of up to
eight 24C02C devices on the same bus for up to 16K
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 and TDFN, 8-pin MSOP and
TSSOP packages.
