The H8SX/1664F is the latest and fastest addition to the quickly expanding family of high performance H8SX 32bit microcontrollers.

Renesas Technology Europe announces the availability of the H8SX/1664F, the latest, and fastest, addition to the quickly expanding family of high performance H8SX 32bit microcontrollers.

The H8SX/1664F offers 50DMIPS performance at 3.3V/50MHz, and is supported by 512Kbyte of full-speed zero-wait embedded Flash and 40Kbyte 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.

The devices high performance and excellent connectivity make it ideal for electronic point of sales (EPOS) applications, health monitoring and fitness gadgets, building/industrial automation and PC peripherals.

Each of the device's serial ports are independent and have their own baud rate generator and four vectored interrupts per channel.

They support LSB or MSB-first shift directions and can run as fast as 720Kbit/s 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 16bit timer unit (TPU) with 20ns resolution and up to 16 input-capture/output-compare.

It also includes: additional 8bit timers; real time outputs that can generate up to eight channels of data patterns - useful for stepper motors for example; a watchdog timer; a 10bit ADC and 8bit DAC; a 32kHz subclock and up to 92 general purpose input/output lines.

The H8SX/1664F is upwards compatible with other H8 microcontrollers.

It is available immediately in a 144-pin RoHS-compliant LQFP package and is supported by Renesas' popular E10A-USB on-chip-debugger.

A Renesas starter kit (RSK) for the device will be available in the Q3 2006.
