Renesas plans new processor for next year
Tuesday 27 May 2008
Renesas Technology will start sampling the first 32-bit microcontrollers based on its new Cisc processor core early next year.
The RX processor has been in development for two years and is intended to unify the two cores which are the basis of the company’s H8 and M16C microcontroller lines.
“The new core combines features of both H8 and M16C, the register architecture with bit manipulated instructions,” Matthew Trowbridge, CEO of Renesas Technology Europe told EW.
For Renesas the importance of the RX core is full compatibility with the existing H8 and M16C based microcontrollers.
Renesas was created five years ago from the merger of the Hitachi and Mitsubishi chips businesses both of which had their own established MCU ranges.
“We have spent a lot of time unifying the peripherals and the development tools,” said Trowbridge.
The RX family will consist of a range of 32-bit MCUs, the RX600 series, and a range of lower power 16-bit devices, the RX200 series.
RX600 series will offer 200MHz performance and the single-cycle flash access which Renesas has put a great emphasis on. The 32-bit RX600 will be the first to appear next year while the 16-bit RX200 will follow in 2010.
The power efficiency of the MCU will be 0.5mA/MHz. There will be 4Mbyte of on-chip flash and up to 256kbyte of SRAM.
According to Trowbridge, there will be a 30 per cent reduction in object-code size compared to existing products.
Microcontrollers represent a major part of the company’s business and in Europe MCUs are by far it biggest business representing 60 per cent of sales, said Trowbridge.
According to Trowbridge, the European market where Renesas competes with leading supplier Freescale, takes 30 per cent of the global consumption of microcontrollers and has an even bigger influence on MCU-based designs.
