The IS24C32A/B and IS24C64A/B contain a memory array of 32Kbits (4K x 8) and 64K-bits (8K x 8), respectively. Each device is organized into 32 byte pages for page write mode. This EEPROM is offered in wide operating voltages of 1.8V to 5.5V (IS24Cxx-2) and 2.5V to 5.5V (IS24Cxx-3) to be patible 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 and 8-pin TSSOP packages. The IS24C32A/32B/64A/64B (IS24CXX) maintains patibility 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...
