IS24C32A/B  
IS24C64A/B  
ISSI  
64K-bit/32K-bit  
2-WIRE SERIAL CMOS EEPROM  
APRIL2006  
FEATURES  
DESCRIPTION  
• Two-Wire Serial Interface, I2CTM Compatible  
–Bi-directional data transfer protocol  
• Wide Voltage Operation  
The IS24C32A/B and IS24C64A/B are electrically  
erasable PROM devices that use the standard 2-  
wire interface for communications. The IS24C32A/B  
and IS24C64A/B contain a memory array of 32K-  
bits (4K x 8) and 64K-bits (8K x 8), respectively.  
Each device is organized into 32 byte pages for  
page write mode.  
–Vcc = 1.8V to 5.5V  
• 400 KHz (2.5V) and 1MHz (5.0V) Compatible  
• Low Power CMOS Technology  
–Standby Current less than 6 µA (5.0V)  
–Read Current less than 2 mA (5.0V)  
–Write Current less than 3 mA (5.0V)  
• Hardware Data Protection  
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-pin TSSOP, and 8-pin MSOP packages.  
–IS24C32A/64A: WP protects entire array  
–IS24C32B/64B: WP protects top quarter of  
array  
• Sequential Read Feature  
The IS24C32A/32B/64A/64B (IS24CXX) 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 IS24CXX  
has a Write Protect pin (WP) to allow blocking of  
any write instruction transmitted over the bus.  
• Filtered Inputs for Noise Suppression  
• Self time write cycle with auto clear  
5 ms max.@ 2.5V  
• Organization:  
–IS24C32A/B: 4Kx8 (128 pages of 32 bytes)  
–IS24C64A/B: 8Kx8 (256 pages of 32 bytes)  
• 32 Byte Page Write Buffer  
• High Reliability  
–Endurance: 1,000,000 Cycles  
–Data Retention: 100 Years  
• Automotive and Industrial temperature ranges  
• 8-pin PDIP, 8-pin SOIC, 8-pin TSSOP, and 8-pin  
MSOP packages  
• Lead-free Available
