RISC MCUs claim cost-effective
performance
The SH/Tiny family of low cost 32bit RISC microcontrollers claims significantly higher cost-performance than other products on the market.
Renesas Technology Europe has announced a range of low cost 32bit RISC microcontrollers, dubbed the SH/Tiny family, that offer significantly higher cost-performance than other products on the market The family starts with four derivatives featuring 64 and 128Kbyte high-speed embedded Flash memory in 48- and 64-pin packages

The H8/38004F MCU offers extremely low power consumption together with 32Kbyte single-supply on-chip Flash memory and is the first in the SLP series that is available in a 64-pin quad flatpack.
They boast 65DMIPS at 50MHz fully supported by zero-wait-state Flash and 8Kbyte RAM.
The new family is ideally suited for cost-critical consumer systems with tight real-time requirements, such as electrical motor drives in white goods and cost- critical industrial motor drive applications.
The SH/Tiny family uses a SH-2 RISC CPU core that has 16 general purpose 32bit registers, a five stage pipeline and a hardware 32 x 32 multiplier.
The instruction set is specifically designed to support C language programming.
To facilitate fast and low latency response to events, the CPU is supported by a vectored interrupt system that responds to events within eight cycles.
The devices also feature the highly sophisticated multifunction timer pulse unit (MTU2), which can be used as a general purpose timer and to drive three-phase motors.
For that, MTU2 has a fast hardware emergency PWM shutdown input, automatic dead time setting, a phase-counting mode for quadrature encoders and can trigger an ADC analogue conversion so that measurement of relevant motor currents occurs exactly on time.
The 10bit resolution, 2us fast double ADC is designed to support motor drives.
It has two independent sample and hold units to be able to sample two currents simultaneously, as required in many motor drives.
Other peripherals include a watchdog timer, two channel compare-match-timer, three serial ports and up to 45 general purpose I/O.
Furthermore, the SH/Tiny microcontrollers have an on-chip debug facility to enable low cost development using the popular Renesas E10A-USB debugger.
An evaluation board is also available.
The new devices operate at 5V/50MHz and are available immediately in two different RoHS-compliant 64-pin QFP packages, one with 0.8mm pin pitch and one with 0.5mm pin pitch.
A 0.65mm pin pitch 48-pin QFP is due to follow in March 2006.
