RX23W Group 1. Overview

Low power

consumption

Low power consumption

functions

 Module stop function

 Three low power consumption modes

Sleep mode, deep sleep mode, and software standby mode

 Low power timer that operates during the software standby state

Function for lower operating

power consumption

 Operating power control modes

High-speed operating mode, middle-speed operating mode, and low-speed operating mode

Interrupt Interrupt controller (ICUb)

 Interrupt vectors: 148

 External interrupts: 7 (NMI, IRQ0, IRQ1, IRQ4 to IRQ7 pins)

 Non-maskable interrupts: 6 (NMI pin, oscillation stop detection interrupt, voltage monitoring 1

interrupt, WDT interrupt, IWDT interrupt, and VBATT power monitoring interrupt)

 16 levels specifiable for the order of priority

DMA DMA controller (DMACA)

 4 channels

 Three transfer modes: Normal transfer, repeat transfer, and block transfer

 Activation sources: Software trigger, external interrupts, and interrupt requests from peripheral

functions

Data transfer controller

(DTCa)

 Transfer modes: Normal transfer, repeat transfer, and block transfer

 Activation sources: Interrupts

 Chain transfer function

I/O ports General I/O ports 85-pin/56-pin

I/O: 43/29

 Input: 1/1

Pull-up resistors: 43/29

Event link controller (ELC)

 Event signals of 59 types can be directly connected to the module

 Operations of timer modules are selectable at event input

 Capable of event link operation for port B and port E

Multi-function pin controller (MPC) Capable of selecting the input/output function from multiple pins

Timers 16-bit timer pulse unit

(TPUa)

 (16 bits × 6 channels) × 1 unit

 Maximum of 10 pulse-input/output possible

 Select from among seven or eight counter-input clock signals for each channel

 Supports the input capture/output compare function

 Output of PWM waveforms in up to 9 phases in PWM mode

 Support for buffered operation, phase-counting mode (two-phase encoder input) and cascade

connected operation (32 bits × 2 channels) depending on the channel.

 Capable of generating conversion start triggers for the A/D converters

 Signals from the input capture pins are input via a digital filter

 Clock frequency measuring method

Port output enable 2

(POE2a)

Controls the high-impedance state of the MTU’s waveform output pins

Compare match timer

(CMT)
