Renesas Technology Europe has announced that it has added the fastest member to date to its quickly expanding family of high performance H8SX 32-bit microcontrollers. The new H8SX/1664F offers 50 Dhrystone MIPS performance at 3,3 V/50 MHz, and is supported by 512 KB of full-speed zero-wait embedded Flash and 40 KB RAM. It also boasts a USB slave module and six serial ports, which support async, sync, ISO/IEC7816-3 and IrDA modes, as well as two channels of IIC.
Each of the device's serial ports is independent and has its own baud rate generator and four vectored interrupts per channel. They support LSB or MSB-first shift directions and can run as fast as 720 Kbps in asynchronous mode. All the connectivity modules are supported by either the direct memory access (DMA) or the data transfer controller (DTC) so that no CPU performance is wasted in moving the data to or from the modules. The high performance H8SX CPU provides superior capabilities to effectively handle the data streams into or from the many interfaces.
The device's peripheral set features a sophisticated six channel 16-bit timer unit (TPU) with 20 ns resolution and up to 16 input capture/output compare. It also includes additional 8-bit timers; realtime outputs that can generate up to eight channels of data patterns - useful for stepper motors for example; a watchdog timer; a 10-bit ADC and 8-bit DAC; a 32 kHz subclock and up to 92 general purpose input/output lines.
The H8SX/1664F is upwards compatible with the company's other H8 microcontrollers. It is available in a 144-pin RoHS-compliant LQFP package and is supported by Renesas' popular E10A-USB on-chip-debugger.
