USB Support for Renesas M16C/6C Microcontroller

20 APRIL 2009

Renesas Technology Europe, its Gold Alliance Partner Thesycon and MSC Vertriebs GmbH today announced the immediate availability of a complete USB stack to support the Renesas Starter Kit (RSK) RSKM16C/6C, based on the M16C/6C.
The M16C/6C is a part of the popular M16C microcontroller platform1 with added support for USB 2.0. The M16C/6C product group includes a total of 16 different models, and the new components are completely compatible with earlier versions. The new USB 2.0 compliant, full-speed 12 MB/s interface supports standard Control, Bulk and Interrupt transfer types. The components include the M16C/60 16-bit CISC CPU core that works with clock rates of up to 32 MHz and a power supply of between 2.7 and 5.5 VDC.
The software stack complies with the USB 2.0 specification and supports Control, Bulk and Interrupt transfer modes at maximum speed. It also includes complete USB request processing and expanded error recovery mechanisms for faultless operation. The USB stack firmware is written in ANSI-C and supports Renesas’ High-Performance Embedded Workshop (HEW) development environment. To facilitate integration, the software is designed as a library and provided in source code form. The library does not require specific operating system support, enabling it to be integrated into any embedded operating system and used in standalone applications.
