High density Flash memories for BIOS and code storage applications

16 July 2003 DSP, Micros & Memory Industrial (Industry) Products

ST Microelectronics has expanded its broad range of firmware hub (FWH) and low pin count (LPC) Flash memories with the introduction of higher density and higher performance 16 Mb Flash devices: the M50FW016 (2 Mb x 8, FWH, uniform block) and M50LPW116 (2 Mb x 8, LPC, boot block).

ST says it is the first company to offer a complete range of Flash memories for PC BIOS from 2 to 16 Mb. The new 16 Mb devices are also the first on the market to be compliant with the LPC interface specification (Rev. 1.1), allowing the M50FW016 to support multibyte firmware memory read/write cycles, with the M50LPW116 able to support read/write memory cycles. With the multibyte read operation, transfer rate can grow up to 15,6 MB per second, faster than any existing serial Flash interface, claims ST.

The M50FW016 and the M50LPW116 specifications have been defined in cooperation with motherboard designers to ensure full compliance with their requirements. These devices are suitable for computer applications, such as servers, PCs and workstations to store system and video BIOS, embedded operating system/application software, configuration parameters, etc. In addition, the Flash memories are suited for code storage applications, such as printers, digital still cameras, set-top boxes, DVD-RW drives, taking advantage of a fast serial interface.

The products are available in TSOP40 (10 x 20 mm) package; (PLCC32 on demand).
