RX210 Group User's Manual: Hardware

Overview of the RX210 Group

The first product in the RX200 Series

The RX210 Group has a wide operating voltage range of 1.62 V to 5.5 V and can execute calculations at 78 DMIPS (Dhrystone million instructions per second) at up to 50 MHz high-speed operation. Furthermore, it achieves 0.2 mA/MHz low power performance when operating at 50 MHz. Consumption current in deep software standby mode is a mere 0.45 µA. A wide lineup of 48 KB to 1 MB ROM and 48-pin to 145-pin products is available.


The main specifications of the RX210 microcontrollers are as follows.

Item Description
CPU Max. 50 MHz (1.56 DMIPS/MHz, max. approx. 78 DMIPS)
Operating voltage 1.62 V to 5.5 V
Memory ROM: 64 KB to 1 MB
RAM: 12 KB to 96 KB
Data flash: 8 KB
Safety functions Clock frequency accuracy measurement circuit (CAC), data operation circuit (DOC), independent watchdog timer (IWDTa), ADC self-diagnostic function/disconnection-detection function, CRC calculator (CRC)
Peripheral functions Event link controller (ELC), multifunction pin controller (MPC), three-phase motor control timer (MTU2), 12-bit A/D converter (S12ADb)
Pin count/packages LQFP 64(Under Development), 80pin, LFQFP 48, 64, 80, 100, 144
TFLGA 100, 145pin
Smooth shift from existing product Inherits pin arrangement of the M16C and the peripheral functions of the H8 and M16C, so smooth shift from existing product is possible

Memory vs. Package Lineup

A package lineup ranging from 48 to 145 pins is planned, and we plan to support small packages such as QFN and LGA sequentially.

In terms of on-chip memory, the product lineup plans to cover up to 1 MB of flash memory, 96 KB of RAM, and 8 KB of E2 data flash. Functions for improved usability include an event link controller (ELC) for activating a peripheral module from another peripheral module without passing through an intermediary CPU, and a multifunction pin controller (MPC) enabling flexible selection of function for pins that have been allocated a variety of functions.
Powerful peripheral functions, such as a 12-bit AD converter with a conversion time of 1 µs and MTU2, which is capable of a variety of PWM control, are built in.
