RX220 Group User's Manual: Hardware

Overview of the RX220 Group

The RX220 Group is a low power entry-level 32-bit microcontroller.
The RX220 Group of products is the slimmed-down version of the higher model RX210 Group, and has very high compatibilility in terms of pin arrangement and on the software level.

The main specifications of the RX220 microcontrollers are as follows.

Item Description
CPU Max. 32 MHz (1.56 DMIPS/MHz, max. approx. 50 DMIPS)
Operating voltage 1.62 V to 5.5 V
Memory ROM: 32 to 256 KB, RAM: 4 to 16 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 48-pin to 100-pin packages, small LGA, wide pin pitch LQFP (planned)
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

Specifications

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.
