SUNNYVALE, Calif. -- June 18, 2002 -- In line with the increased demand for highly functional single-chip Universal Serial Bus (USB) solutions for digital audio applications, the Electronic Device Group of Mitsubishi Electric & Electronics USA, Inc., introduced a 16-bit embedded microcontroller (MCU) with full-speed USB functions. The M16C/245 (M30245) integrates high capacity memory and USB 2.0 functionality with an M16C MCU core -- noted for its C language efficiency, fast processing speed, low power consumption, and exceptional EMI/EMS performance -- into a single chip. The device is also capable of performing communication data operation processing and main processing, making it ideal for portable audio applications and high-speed Internet content delivery.

The MCU is the latest addition to Mitsubishi Electric's USB family, and was co-developed by Mitsubishi Electric System LSI Design Corporation in Japan and Mitsubishi Electric's Design Engineering Center, based in North Carolina.

"The USB market is driven by a number of factors: speed, functionality, and due to the demand for smaller portable devices, integration," said Richard Sessions, director of embedded systems at Mitsubishi Electric & Electronics USA, Inc. "By utilizing our extensive design resources in Japan and North America, we have combined our expertise in USB with our industry-leading M16C MCU core to meet customer demand and deliver optimal speed with increased functionality in a single chip."

Using a small, thin 100-pin LQFP package, the device features up to a maximum of nine endpoints. The M16C/245 can perform transfer mode on each endpoint, while not only the buffer size, but also each endpoint on transfer mode can be set optionally. A multi-function serial I/O that can transfer up to 32-bit data has been embedded into two channels, which allows serial sound interface with audio codecs. Additionally, there is a CRC (CRC-CCITT, CRC-16) operations circuit embedded for various memory cards, making it possible to select a generative polynomial best suited for the product application.

Packaging and Availability
Mitsubishi Electric's M16C/245 (M30245) is available in a 100-pin LQFP package. Samples will be available in July 2002, with volume production scheduled for September 2002.
