512Kbit serial EEPROMs come in tiny packs

STMicroelectronics has leveraged its advanced non-volatile memory technology to deliver two new 512Kbit devices that offer the highest density memories available in 2mm x 3mm x 0.6mm 8-pin MLP. Pin compatibility with memories of lower density allows designers to upgrade products quickly and efficiently by changing devices without redesigning the board.

The M95512 and the M24512 serial EEPROMs deliver non-volatile storage in low-pin-count packages, suitable for many consumer, industrial, medical and communication products. The devices' built-in byte-mode erasing capability allows easy parameter update; and 128byte page write, together with 5ms write time, results in rapid programming of assembled boards on the production line.

In addition, with read current as low as 2mA and stand-by current less than 5?A, the new memories save energy in power-sensitive equipment such as battery-powered personal media devices or professional portable instruments. The wide operating-voltage range, from 1.8V to 5.5V, allows the same device to be used across many applications and product variants. Both types are also offered with an operating range of 2.5V to 5.5V.

The M95512 features a 20MHz SPI port, and with it, achieves data transfer speeds equal to the fastest serial EEPROMs currently available. Meanwhile the M24512 has an I²C interface supporting 400kHz Fast-mode or 1MHz Fast-mode Plus.

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-, 128- 512Kbit densities. A 256Kbit device is planned for Q4 09.

The M95512 and M24512 in MLP 2mm x 3mm packages are available in mass production and are priced from $0.80 for high-volume orders.
