RX634

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.
