The 24C32 and 24C64 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 operates in a wide voltage range of 1.8V to 5.5V to be compatible with most application voltages. designed this device family to be a practical, low-power 2-wire EEPROM solution. The devices are available in 8-pi...
