Microchip Technology has released 24CS512, the first commercially available I2C Serial EEPROM with support for 3.4 Mbit/s data rates. This high-speed I2C EEPROM is 3 to 4 times faster than the existing EEPROMs available in the market. It offers high-speed mode operation, software write-protection and factory programmed serial numbers.
The 24CS512 I2C Serial EEPROM provides 512 Kbits of Serial EEPROM, utilizing an I2C (two-wire) serial interface with high-speed mode capability. The device is organized as 65,536 bytes of 8 bits each (64 Kbytes) and is optimized for use in consumer and industrial applications where reliable nonvolatile memory storage is essential. It allows up to eight devices to share a common I2C (two-wire) bus and is capable of operation across a broad voltage range (1.7V to 5.5V).
This high-speed mode I2C serial EEPROM expands the available options for meeting complex design criteria. The device also contains a Configuration register, which allows the write protection behavior to be configured for legacy hardware write protection or enhanced software write protection which allows the user to protect any of the eight independent 64-Kbit zones.
