  • 24C64 IC - 64K bit Serial I2C Bus EEPROM IC

The 24C64 are electrically erasable PROM devices that use the standard 2- wire interface for communications. The 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-pin PDIP, 8-pin SOIC, 8-pin TSSOP, 8-pad DFN, and 8-pin MSOP packages. The 24C64 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 24CXX has a Write Protect pin (WP) to allow blocking of any write instruction transmitted over the bus.
