288 MIPS superscalar MCU for high-end motor drives

9 August 2006 DSP, Micros & Memory

Renesas Technology Europe's SH7201 is a high-speed microcontroller based on the company's SH2A CPU core. The new device delivers 288 MIPS performance from its superscalar CPU core, has a floating point unit and the world's fastest interrupt response at only six clock cycles (at 120 MHz this is 50 ns) according to the company.

Together with the powerful MTU2 timer unit supporting 3-phase PWM, the SH7201 device is well-suited for high-end electrical motor drives, robotics and other realtime applications in industrial, home and office automation.

The SH7201 boasts eight channels of fifo-ed serial ports, three channels of I²C and two channels of CAN. The traffic to and from these channels is supported by an 8-channel DMA. The device also has six channels of 16-bit timers with 21 output compare/input capture registers and special PWM modes to facilitate driving electrical motors of any kind. The PWM modes occupy only a third of the MTU2, while the remaining channels understand quadrature encoder feedback and can handle general timer tasks. Beyond the MTU2, the SH7201 has two channels of general purpose 8-bit timers, a realtime clock and a watchdog timer.

The large peripheral set is completed by an 8-channel 10-bit ADC, a 2-channel 8-bit DAC and up to 123 I/O lines. The performance is supported by a flexible bus state controller including SDRAM interface and by 2x 8 KB cache, as well as 32K high-speed RAM.

The SH7201 comes in a 176-pin LQFP RoHS-compliant package and is supported by Renesas' E10A-USB on-chip debugger, as well as by Lauterbach's Trace32-ICD. An evaluation board is available.
