IS24C02B

Notes:
1. Stress greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.

The IS24C01B and IS24C02B are electrically erasable PROM devices that use the standard 2-wire interface for communications. The IS24C01B and IS24C02B contain a memory array of 1K-bits (128 x 8) and 2K-bits (256 x 8), respectively. Each device is organized into 8 byte pages for page write mode.

This EEPROM operates in a wide voltage range of 1.8V to 5.5V to be compatible with most application voltages. ISSI designed this device family to be a practical, low-power 2-wire EEPROM solution. The devices are available in 8-pin PDIP, 8-pin SOIC, 8-pad DFN, and 8-pin TSSOP packages.

The IS24C01B/02B maintains compatibility with the popular 2-wire bus protocol, so it is easy to use in applications implementing this bus type. The simple bus consists of the Serial Clock wire (SCL) and the Serial Data wire (SDA). Using the bus, a Master device such as a microcontroller is usually connected to one or more Slave devices such as this device. The bit stream over the SDA line includes a series of bytes, which identifies a particular Slave device, an instruction, an address within that Slave device, and a series of data, if appropriate. The IS24C01B/02B has a Write Protect pin (WP) to allow blocking of any write instruction transmitted over the bus.
