Renesas Technology America, Inc. has released a new SuperH® microcontroller (MCU) for high-end motor control applications. The 32-bit SH7286 offers up to 1Mbyte of fast MONOS (Metal Oxide Nitride Oxide Silicon) embedded flash memory. The fast flash memory combined with the powerful 100MHz CPU enables sophisticated single-chip designs for high-precision motor drives, AC servos and general-purpose industrial inverters that previously required two MCUs.
Peripheral functions built into the SH7286 include two multi-function timer units, MTU2 and MTU2S, to drive two motors simultaneously. The comprehensive MTU2 includes six channels of 16-bit timers, support for up to 16 input-capture/output-compare functions, and a three-phase pulse width modulation (PWM) capability for electric motors. Additional motor-control features are enabled by two quadrature-encoder feedback systems and two special channels that can measure dead times at the power stage for maximizing efficiency and preventing destructive operation. Port output enable (POE) pins with a fast, deterministic response time help ensure safe motor shutdowns.
The three 12-bit A/D converter modules with a total of 12 channels have a fast 1.0µs conversion time. Each A/D can be triggered by the MTU2 or MTU2S with an additional programmable delay time for supporting algorithms such as single-shunt motor drive. Extensive communication capabilities are provided by CAN, USB 2.0, serial communication interface (SCI), synchronous serial communication unit (SSU), and IIC3 functions.
The powerful superscalar SH-2A CPU core offers unprecedented 2.0 DMIPS/MHz performance and interrupt latency of just six cycles. The SH7286 has a 3.0V to 5.5V operating range and comes in two 176-pin LQFP packages: 20x20mm with 0.4mm pitch or 24x24mm with 0.5mm pitch.
The SH7286 is supported by the Renesas Starter Kit (RSK) – a user-friendly evaluation tool with all components required to quickly evaluate and develop out of box. The kit contains a power supply, E10a on-chip debugger, USB cable and a CD with software development tools and source files for exercising all peripherals on the board. The board contains an SH7286 MCU with LCD display, USB, CAN and RS-232 connectors, potentiometer and LEDs. A limited-time coupon code is available from the Renesas Technology America site (www.america.renesas.com/ReachSH/a) to purchase the RSK at a discounted price.
The SH7286 is also supported by a comprehensive suite of tool chain by third parties, including an integrated development environment (IDE), compiler and debugger by Green Hills and KPIT GNU Tools, and RTOS and middleware support from Express Logic, Micrium, and SEGGER.
