DESCRIPTIOn
The IS24C01B and IS24C02B are EEPROM de-
vices that use the industrial standard 2-wire, I
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 de-
vice 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 applica-
tion voltages. ISSI designed this device family to
be a practical, low-power 2-wire EEPROM solution.
The devices are offered in lead-free, RoHS, halo-
gen free or Green. The available package types are
8-pin SOIC, TSSOP, DFN, and UDFN.
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 ap-
propriate. The IS24C01B/02B has a
Write Protect pin (WP) to allow blocking of any
write instruction transmitted over the bus.
