3 Renesas families. BEST CHOICHE! Lower-cost. Highest-Performances. Lower system cost. Mid-end. High-performances. High Integration. Low-end Bologna 26 Settembre 2007 pag 6/N Higher Efficiency & Lower Noise. Sinusoidal control to reduce mechanical noise. New driving techniques to reduce switching losses. Better EMI & EMS to reduce filtering. 5V operation for better EMS characteristics. Bologna 26 Settembre 2007 pag 7/N Title goes here 3

4 Sinusoidal waveform to reduce mechanical noise. MCRP05 and MCRP01 delivers corrected sinusoidal waveform to reduce acoustical noise. That s the biggest advantages of BLAC vs. BLDC. It has lower torque ripple vs. V/f algorithms. Bologna 26 Settembre 2007 pag 8/N New driving techniques to reduce switching losses. Switching losses are one of the biggest responsible for efficiency reduction. Newer control techniques can reduce this loss by 1/3. This technique can only be used together with high performance vector control. This allows cost reduction both for heat-sink and for power stage. Bologna 26 Settembre 2007 pag 9/N Title goes here 4

5 EMS SH Superior results. EMS1 [CDM] EMS2 [HBM] Bologna 26 Settembre 2007 pag 10/N EMI Superior results. The SH2 Tiny [as well as the H8 Tiny] can reach superior results that are well above the homologation required levels. Bologna 26 Settembre 2007 pag 11/N Title goes here 5

6 5V operation for better EMS characteristics. 5V operation is intrinsically more robust than 3V one. Even if it requires higher silicon area Renesas supplies 5V operation devices for all his product families. Bologna 26 Settembre 2007 pag 12/N Performances. Double precision Floating Point Unit.

7 Double precision Floating Point Unit. The FPU in the SH2A-FPU core delivers 200 MFLOPS peak performance for simple operations such as add. The table shows execution times for functions in double precision in nano seconds. The FPU supports single and double precision, IEEE754 compliant. Two rounding modes: to nearest or to zero. 16x 32bit registers (single precision) or 8x 64bit registers (double precision) Supports FMAC multiplication and accumulation Bologna 26 Settembre 2007 pag 14/N Proven Reliability. The most valuable example. 25 MILLION MICROCONTROLLERS SHIPPED FOR WORLD S LARGEST AUTOMATIC METER READING PROGRAMME Nurenberg, 22 February, 2005 Renesas Technology Europe has achieved the milestone of shipping 25 million H8/3062 and H8S/2134 microcontrollers to Enel, one of the world s major electricity companies and the main operator in Italy. In 2001, Enel launched a unique and challenging project in advanced automated meter management (AMM) systems that will be fully deployed to more than 30 million customers by the end of This is believed to be the largest ever shipment of microcontrollers for a single metering project anywhere in the world. As the world s number one supplier of flash microcontrollers, Renesas Technology was able to offer Enel a large range of flash devices, all with high performance CPU cores, together with a reliable flash process and the capability for high volume production. The H8/3062 and H8S/2134 microcontrollers were selected for their high reliability (zero failures in 25 million pieces shipped), scaleable architecture (protecting Enel s software investment) and their high integration (enabling system costs to be optimised). Renesas Technology continues to develop scaleable microcontroller families dedicated to metering applications, offering the highest memory and peripheral integration combined with low power consumption techniques suitable for battery driven applications. 25 million H8/3062 and H8S/2134 microcontrollers to Enel This is believed to be the largest ever shipment of microcontrollers for a single metering project anywhere in the world.

8 MONOS Flash World s fastest embedded Flash Technology. 10ns read access time now, 5ns soon. MONOS: Metal-Oxide-Nitride-Oxide-Silicon Nitride stops electrons from leaking off the floating gate in case of defects. Hence the cell can be made small whilst it is still highly reliable. Small means FAST and cost effective. It also enables BIG (currently up to 4MByte) Flash modules.
