Renesas Electronics Corp. has revealed its roadmap for next-generation MCUs and microprocessors (MPUs). Among the new developments, the company plans to use the company's 40nm metal oxide nitride oxide silicon (MONOS) embedded flash technology with its RX family of high-performance, general-purpose 32bit MCUs. Renesas is also expanding the RX Family to include the lowest power, lowest cost 32bit MCU for the embedded market, integrating as little as 8KB of flash memory, added the company.

Renesas likewise announced plans to introduce a family of ARM-based high-performance embedded MPUs. The new RZ Family will be deployed for application areas that require high-speed data processing in excess of 300MHz. Together, these new products will enable efficient, secure and connected electronic systems that improve our overall quality of life, the company indicated.

Renesas will expand the current RX family to include devices from 8KB-8MB of embedded flash memory with compatible instruction set, peripherals and hardware and software tools set. The Renesas RX family can support applications from small MCU application equipment in which cost is the most important factor to applications that require high data processing performance.

At the high-end, Renesas will develop a higher speed version of RX600 Series (120MHz) and a high-performance RX700 Series (240MHz, with target performance of 3.6Coremark/MHz). These products will adopt a 40nm MONOS process and, will include up to 8MB of on-chip flash memory with single cycle access at 120MHz and enhanced connectivity and graphics features. The RX devices with enhanced FPU and DSP functions will run complex routines in half of the cycles needed with other competing 32bit architectures in the market today, noted the firm.

The RX100 Series MCUs, which is based on the proven 130nm, low-power process technology, can run at 32MHz, delivering1.56DMIPS/MHz throughput, consuming only 155uA/DMIPS power in full active mode and only 350nA in the standby mode as target.

The Renesas MONOS embedded flash technology, which can operate in temperatures up to 125C is well suited for the long-term data retention needed in high-reliability automotive and medical applications. In addition to the program memory, devices will also include data memory that will deliver 20-year data retention even after 100,000 write cycles. The mature 40nm Flash process is currently used in the production of Renesas' RH850 Family automotive MCUs.

The 40nm versions of the RX600 MCUs are in development, and the first sample with dual Ethernet, 4MB of MONOS Flash and 512KB SRAM is scheduled to be available in 2Q13.

Samples of the RX100 product series, ultra-low power 32bit RX devices offering flash memory integration from 8KB-128KB are scheduled for 1Q13.

Renesas plans to provide the sample of the first RZ product, a high-performance, 40nm device RZ/A Series is scheduled to be available in 2Q13.
