Up to 54 MHz operation and built-in remote control receiver and HDMI-CEC for linking to home appliances

 

The RX634 Group operates at single voltage supply of 3.3 V but also at 5 V and performs at up to 54 MHz CPU clock. The RX634 group memory lineup offers up to 2 MB code flash, 128 KB RAM and 32 KB Data flash embedded. RX634 is available in a 144-pin package. Compared to the RX630 group the RX634 added HDMI-CEC function and Remote Control Signal Receiver function which are typical required features for digital home appliances. At the same time RX634 has been feature optimized by removing CAN, USB and RTC function to suit the market needs even better. Therefore RX634 suits ideally as a multimedia devices group, due to feature set as well as high performance. In addition RX634 group incorporate multi function timer (MTU2) and high speed 12-bit A/D converter enable to hold 3 channels at the same timing, which are typically required for industrial motor control applications.

标题 描述
e² studio This integrated development environment (IDE) is based on the popular combination of the open-source Eclipse IDE and its CDT plug-in that enables C/C++ language development.
CS+ This integrated development environment (IDE) can be used for coding, assembly, compiling, and simulation. CS+ is also included with starter kits.
E2 emulator Lite This entry-level on-chip debugging emulator provides functionality equivalent to that of the E1 emulator at a low price.
E2 emulator This on-chip debugging emulator has advanced features that improve the efficiency of development. In addition to the basic functions from debugging to flash programming, this emulator supports hot plug-in and external triggers as standard items. This emulator also helps to reduce development time by downloading at high speeds (compared to the E1 emulator) and the ability to work in combination with various solutions such as the tuning of current drawn by systems under development.
E20 emulator This on-chip debugging emulator has enhanced debugging facilities such as large-capacity tracing and real-time RAM monitoring when used in combination with RX600 and RX700 MCUs (this emulator provides debugging functionality equivalent to that of the E1 emulator for other MCUs).
E1 emulator This on-chip debugging emulator is a standard model which provides basic debugging functions (production is to be discontinued at the end of December 2019).
