RX63N Group, RX631 Group 1. Overview
Low power
consumption
Low power
consumption facilities
 Module stop function
 Four low power consumption modes
Sleep mode, all-module clock stop mode, software standby mode, and deep software
standby mode
 Battery backup function
Interrupt Interrupt controller
(ICUb)
 Peripheral function interrupts: 187 sources
 External interrupts: 16 (pins IRQ0 to IRQ15)
 Software interrupts: One source
 Non-maskable interrupts: 6 sources
 Sixteen levels specifiable for the order of priority
External bus extension  The external address space can be divided into nine areas (CS0 to CS7, SDCS), each
with independent control of access settings.
Capacity of each area: 16 Mbytes (CS0 to CS7), 128 Mbytes (SDCS)
A chip-select signal (CS0# to CS7#, SDCS#) can be output for each area.
Each area is specifiable as an 8-, 16-, or 32-bit bus space.
The data arrangement in each area is selectable as little or big endian (only for data).
 SDRAM interface connectable
 Bus format: Separate bus, multiplex bus
 Wait control
 Write buffer facility
DMA DMA controller
(DMAC)
 4 channels
 Three transfer modes: Normal transfer, repeat transfer, and block transfer
 Activation sources: Software trigger, external interrupts, and interrupt requests from
peripheral functions
EXDMA controller
(EXDMACa)
 2 channels
 Four transfer modes: Normal transfer, repeat transfer, block transfer, and cluster transfer
 Single-address transfer enabled with the EDAKn signal
 Capable of direct data transfer to TFT LCD panels
 Activation sources: Software trigger, external DMA requests (EDREQn), and interrupt
requests from peripheral functions
Data transfer
controller (DTCa)
 Three transfer modes: Normal transfer, repeat transfer, and block transfer
 Activation sources: External interrupts and interrupt requests from peripheral functions
