The Microchip Technology Inc. a 2K bit Serial Electrically Erasable PROM with a voltage range to 5.5V. The device is organized as a single block x 8-bit memory with a 2-wire serial interface. Low current design permits operation with typical standby and active currents of only 10 �A and 1 mA respectively. The device has a page-write capability for 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 up to eight 24C02C devices on the same bus for to 16K bits of contiguous EEPROM memory. The device is available in the standard 8-pin PDIP, 8-pin SOIC (150 mil), and TSSOP packages.

*Notice: Stresses above those listed under "Maximum ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at those or any other conditions above those indicated in the operational listings of this specification is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability.

ms Byte or Page mode cycles 25�C, VCC = 5.0V, Block Mode (Note 4)

Note 1: Not 100% tested. CB = total capacitance of one bus line in pF. As a transmitter, the device must provide an internal minimum delay time to bridge the undefined region (minimum 300 ns) of the falling edge of SCL to avoid unintended generation of START or STOP conditions. 3: The combined TSP and VHYS specifications are due to Schmitt trigger inputs which provide improved noise spike suppression. This eliminates the need for a TI specification for standard operation. 4: This parameter is not tested but guaranteed by characterization.
