Renesas Electronics Corp. has unleashed the RH850/F1x series of 32bit MCUs for automotive body applications. According to the company, the devices are the first products to be released in the RH850 family of automotive MCUs with on-chip flash memory using the industry's most advanced 40nm process.

The RH850/F1x series is composed of three groups and has a total of more than 50 products from low-end to high-end, the RH850/F1L, RH850/F1M and RH850/F1H. Larger on-chip flash memory capacity from 256KB up to 8MB is offered along with more compact package options (48-pin and up). Dual-core versions are also planned to be available in the RH850/F1H Group. The RH850/F1x series uses the same architecture CPU core and common peripheral functions, and has software compatibility within the same group. They also use the metal oxide nitride oxide silicon structure for flash memory with lower power consumption (0.5mA/MHz for RH850/F1L) and higher reliability.

Renesas improved automotive network functions (example: number of local interconnect network (LIN) channels expanded to 18) and added data encryption function with the RH850/F1x series. These features will help customers build electronic body control units combining energy efficiency, high performance and improved safety, added the company.

Development tools provided by Renesas for the RH850/F1x Series include the Renesas eclipse embedded studio, e2studio and the E1 on-chip debugging emulator, and flash memory programmers. There are also plans to provide support for software conforming to the Automotive Open System Architecture (AUTOSAR) standard.

Samples of the RH850/F1L Group of MCUs are scheduled to be available from 2Q13, priced at $30 per unit. Mass production of the RH850/F1L group is scheduled to begin in FY2014, with the different product versions appearing soon after, and is expected to reach a scale of 3,000,000 units for each version per month by June 2015.
