DESCRIPTION

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.
