Renesas Technology Europe has released the fastest member to date of the company's high performance H8SX family of 32-bit microcontrollers. The H8SX/1653F offers 50 Dhrystone MIPS performance at 3,3 V/50 MHz and is supported by 384 Kbyte of full speed, zero-wait embedded Flash and 40 Kbyte RAM. It also boasts a USB slave module and six serial ports, which amongst them support async, sync, ISO7816 and IrDA modes as well as two I²C channels.
This device is well-suited for applications such as point of sales, the latest generation of health monitoring and fitness gadgets, and for building/industrial automation, says the company.
The serial ports on the H8SX/1653F are all independent from one another, each with its own baud rate generator and with four vectored interrupts per channel. They support LSB or MSB-first shift directions and can run as fast as 720 kbps in asynchronous mode. Furthermore, the connectivity modules are all 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.
In addition to its superior connectivity, the peripheral set features the following: 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; 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 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 microcontrollers used across Europe in many applications. It is available immediately in a 120-pin RoHS-compliant TQFP package and is supported by Renesas' popular E10A-USB on-chip-debugger.
