STMicroelectronics is now putting forth a 256 kbit EEPROM memory IC with a three chip select in a TSSOP8 package. The two-wire gadget includes an I2C serial interface, supports 400kHz protocol and operates over a 1.8V to 3.6V power supply range. STM says the non-volatile M24256 is suited for the telecommunications market and that its TSSOP8 package can save space in mobile applications that need high-density EEPROM in the smallest possible package. The little devil offers a minimum data retention of 40 years and has a guaranteed read/write endurance of at least 1 million cycles.
