■ Real-time clock

 Adjustment functions (30 seconds, leap year, and error)

 Time capture function (for capturing times in response to event-signal input on external pins)

■ Independent watchdog timer

 125-kHz LOCO clock operation

■ Useful functions for IEC60730 compliance

 Oscillation-stop detection, frequency measurement, CRC, IWDT, self-diagnostic function for the A/D converter, etc.

RX630系列评估板

The Renesas Starter Kit for RX630 is intended as a user-friendly introductory and evaluation tool for the RX630 microcontroller. The kit also provides a useful platform for evaluating the Renesas suite of development tools for coding and debugging. This includes a choice of IDEs between the High-performance Embedded Workshop and e2studio.
The Renesas Starter Kit for RX630 may be connected to the host PC using a simple RS232 serial connection or via the included USB E1 on chip debugging interface.

The purpose of the board is to enable the user to evaluate the capabilities of the device and its peripherals by giving the user a simple platform on which code can be run only minutes from opening box. It can also prove an invaluable tool in development by providing a useful test platform for code already debugged using one of our more powerful emulation tools.

This RSK is an evaluation tool for Renesas microcontrollers. This manual describes the technical details of the RSK hardware. The Quick Start Guide and Tutorial Manual provide details of the software installation and debugging environment.

RX630系列评估板主要特性:

This RSK provides an evaluation of the following features:

 Renesas microcontroller programming

 User code debugging

 User circuitry such as switches, LEDs and a potentiometer

 Sample application

 Sample peripheral device initialisation code

The RSK board contains all the circuitry required for microcontroller operation.
