With the new H8SX/1653F, Renesas introduces the fastest member to date of the high performance H8SX family of 32-bit microcontrollers. The device offers 50 Dhrystone MIPS performance at 3.3V/50MHz and is supported by 384 Kbyte of full speed, zero-wait embedded Flash and 40 Kbyte RAM. It also boasts a USB-function module and six serial ports, which amongst them support async, sync, ISO7816 and IrDA modes as well as two channels of I²C. The H8SX/1653F is ideal for electronic point of sales (EPOS) applications, the latest generation of health monitoring and fitness gadgets, and for building/industrial automation.

In addition to its excellent connectivity, the peripheral set features: a highly sophisticated six channel 16-bit timer unit (TPU) with 20 ns resolution and up to eight input capture/output compare; additional 8-bit timers; real-time 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 an 8-bit DAC; and up to 84 general purpose input/output lines.

The H8SX/1653F is upwards compatible with the vast family of H8/S microcontrollers used in many different applications. It is available in a 120-pin RoHS-compliant TQFP package and is supported by Renesas’ popular E10A-USB on-chip-debugger.

For this new device MSC offers an evaluation board and also software-support for the USB interface.
