STMicroelectronics brings two 512-Kbit devices that offer as the company stated the highest density memories available in the industry-standard 2 x 3 x 0.6mm 8-pin Micro Leadframe Package (MLP).

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

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 2 to 128 and 512-Kbit densities. A 256-Kbit device will be available in Q4 2009.

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