STMicroelectronics extends its flash memory portfolio

STMicroelectronics extended its Serial Flash family with 16Mbit M25P16 and 32Mbit M25P32 solutions that have clock speed increased up to 50MHz. The remaining models (512Kbit, 1, 2, 4, 8 Mbit) had their clock speeds increased from 25 to 40 MHz that provided the top places in the market.

The nonvolatile Serial Flash is used to store code and settings in devices like CD/DVD players, Internet consoles, digital TVs, cameras, graphics cards, printers, motherboards, LCD displays, WLAN tools, DSL and cable modems. As a rule, after power is on, this data is sent from the Flash memory to RAM, e.g. for execution (code).

The new chips are organized as 32 and 64 x 512KB sectors, respectively. Similar to other chips, the new solutions utilize 4 pins for addressing, data transfers, management (via SPI-compatible serial interface). Requiring 2.7-3.6V, they consume 8mA at reading, 50ľA in the energy-saving mode, and 1ľA in "deep sleep".

Based on the CMOS technology, chips can store data during 20 years and can withstand up to 100,000 rewrite cycles. M25P16 and M25P32 are offered in 8-pin MLP8 (6x5mm/8x6mm) or 16-pin SO16 packages. Samples are available now, while the volume production is scheduled to Q1 2004.
