STMicroelectronics is shoring up its line of application-specific Flash memory, with one chip line aimed at mobile devices and another primarily at STBs.

The releases will help ST defend its entrenched position as a Flash supplier to numerous markets, ranging from computer peripherals and communications to the automotive and consumer segments.

"The demands of markets such as mobile phones and set-top boxes are best met by Flash memories that have been tailored to the particular applications," said Mario Licciardello, GM of STMicro's Flash memories. "The mutually exclusive requirements of maximizing performance and minimizing both cost and power consumption can only be partly met by moving to new technology generations."

The M58WR128E is a 128Mb chip with an asymmetrical, multibank block architecture that allows the parallel execution of operations. STMicro has also added a 192-bit protection register and security block, comprised of a 64-bit pre-programmed segment and a 128-bit segment that can be programmed once by the user.

The 54MHz chip uses a 1.8V power supply and supports burst mode, fast read and programming operations, and block-level erasing and locking. The device, which is available with access times of 70ns, 85ns, or 100ns, allows asynchronous and synchronous read operations.

For the STB arena, STMicro is offering the 32Mb M58LW032C and 64Mb M58LW064C chips. Although they were developed for STBs, STMicro is also pushing them for other applications, such as cellphones, routers, GPS systems, and multimedia systems in cars.

The chips have x8 and x16 buses, use a 2.7V to 3.6V power supply (with 1.8V I/O) and a synchronous burst read mode at up to 56MHz. Page read mode access time is 110ns/25ns; asynchronous random read operations are performed with an access time of 110ns.

Samples are available now. STMicro will have volumes available in Q2.
