Memory and package lineups have been expanded from the RX610; USB, 12-bit A/D and other enhanced peripheral functions


With flash memory capacities from small to large and package pin counts from low to high, the RX630 Group can satisfy the demands of a variety of embedded devices. All the products of the RX630 Group are equipped with E2 data flash capable of 100,000 rewrites and enhanced peripheral functions with increased numbers of channels including timers, USB 2.0 function module, serial communication interface, I2C bus interface, CAN, 10-bit and 12-bit A/D converter, and 10-bit D/A converter. In particular, built-in features such as RTC with timestamp, temperature sensor, independent WDT, and POR/LVD enable the number of external parts to be reduced. We are also planning on releasing small packages such as LGA and BGA.
