STMicro packs 512-Kb of storage capacity in EEPROM of size 2 x 3mm

ST Microelectronics has announced the availability of two new 512-Kb Serial EEPROM devices in 2 x 3 x 0.6mm 8-lead Micro Leadframe Package (MLP). These new memory chips are pin compatible with earlier EEPROM devices of lower density.

The new devices are the M95512 featuring a 20MHz SPI interface, and the M24512 with an I2C interface supporting 400kHz Fast-mode or 1MHz Fast-mode Plus. With its 20MHz SPI interface. ST Claims, the M95512 achieves data transfer speeds equal to the fastest serial EEPROMs currently available.

The read current is 2milliamps and stand-by current less than 5 microamps. The operating-voltage range is 1.8Volts to 5.5Volts.

Both devices are also available in industry-standard SO-8 and TSSOP-8 packages. These new devices complete a full family of EEPROMs, delivered in MLPs from 2Kb to 128Kb and 512-Kb densities. A 256-Kb device will be available in Q4 2009.

The M95512 and M24512 in MLP 2x3 packages are available in volumes and are priced from $0.80 for high-volume orders.
