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.

... IS24C01B IS24C02B DEVICE OPERATION IS24C01B/02B features serial communication and supports a bi-directional 2-wire bus transmission protocol called I 2-WIRE BUS The two-wire bus is defined as a Serial Data line (SDA), and a Serial Clock line (SCL). The protocol defines any device that sends data onto the SDA bus as a transmitter, and the receiving devices as receivers ...

... After the Master transmits the Start condition and Slave address byte (Fig. 5), the appropriate 2-wire Slave (eg.IS24C02B) will respond with ACK on the SDA line. The Slave will pull down the SDA on the ninth clock cycle, signaling that it received the eight bits of data. The selected EEPROM then prepares for a Read or Write operation by monitoring the bus ...

... IS24C01B IS24C02B READ OPERATION Read operations are initiated in the same manner as Write operations, except that the (R/W) bit of the Slave address is set to “1”. There are three Read operation options: current address read, random address read and sequential read. Current Address Read ...
