I2C bus interface for transfer at up to 1 Mbps (up to 4 channels) RSPI for high-speed transfer (up to 3 channels) ■ External address space 8 CS areas (8 × 16 Mbytes) Multiplexed address data or separate address lines are selectable per area. 8-, 16-, or 32-bit bus space is selectable per area ■ Up to 20 extended-function timers 16-bit MTU2: input capture, output capture, complementary PWM output, phase-counting mode (6 channels) 16-bit TPU: input capture, output capture, phase-counting mode (12 channels) 8-bit TMR (4 channels) 16-bit compare-match timers (4 channels) ■ A/D converter for 1-MHz Operation Up to 21 12-bit channels, and incorporating 1 sample-and-hold circuit Up to 8 10-bit channels, and incorporating 1 sample-and-hold circuit Addition of results of A/D conversion (in the 12-bit A/D converter) Self diagnosis (for the 10-bit A/D converter) ■ 10-bit D/A converter: 2 channels ■ Temperature sensor for measuring temperature within the chip ■ Register write protection function can protect values in important registers against overwriting. ■ Up to 148 pins for GPIO 5-V tolerance, open drain, input pull-up, switchable driving ability ■ Operating temp. range –40 degree C to +85 degree C 圖1.RX630系列方框圖 RX630系列評估板 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系列評估板主要特性: 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. 圖2.RX630系列評估板方框圖 The LCD display module is supplied as a detachable sub-board.
