RX63N Group, RX631 Group 1. Overview
Communication
function
Ethernet controller
(ETHERC)
 Input and output of Ethernet/IEEE 802.3 frames
 Transfer at 10 or 100 Mbps
 Full- and half-duplex modes
 MII (Media Independent Interface) or RMII (Reduced Media Independent Interface) as
defined in IEEE 802.3u
 Detection of Magic Packets
TM

or output of a "wake-on-LAN" signal (WOL)
 Compliance with flow control as defined in IEEE 802.3x standards

DMA controller for
Ethernet controller
(EDMAC)
 Alleviation of CPU loads by the descriptor control method
 Transmission FIFO: 2 Kbytes; Reception FIFO: 2 Kbytes
USB 2.0 host/function
module (USBa)
 Includes a UDC (USB Device Controller) and transceiver for USB 2.0
 Host/function module: one port, function module: one port
 Compliance with the USB 2.0 specification
 Transfer rate: Full speed (12 Mbps)
 Self-power mode and bus-power mode are selectable
 OTG (On the Go) operation is possible
 Incorporates 2 Kbytes of RAM as a transfer buffer
Serial
communications
interfaces (SCIc,
SCId)
 13 channels (SCIc: 12 channels + SCId: 1 channel)
 SCIc
Serial communications modes: Asynchronous, clock synchronous, and smart-card
interface
Multi-processor function
On-chip baud rate generator allows selection of the desired bit rate
Choice of LSB-first or MSB-first transfer
Average transfer rate clock can be input from TMR timers for SCI5, SCI6, and SCI12
Simple I

C
Simple SPI
 SCId (The following functions are added to SCIc)
Supports the serial communications protocol, which contains the start frame and
information frame
Supports the LIN format
I

C bus interfaces
(RIIC)
 4 channels (one of them is FM+)
 Communication formats
I
2
C bus format/SMBus format
Supports the multi-master
Max. transfer rate: 1 Mbps (channel 0)
IEBus (IEB)  1 channel
 Supports protocol control for the IEBus
Half-duplex asynchronous transfer
Multi-master operation
Broadcast communications function
Two selectable modes, differentiated by transfer rate
CAN module (CAN)  3 channels
 Compliance with the ISO11898-1 specification (standard frame and extended frame)
 32 mailboxes each
Serial peripheral
interfaces (SPI)
 3 channels
 RSPI transfer facility
Using the MOSI (master out, slave in), MISO (master in, slave out), SSL (slave select),
and RSPCK (RSPI clock) signals enables serial transfer through SPI operation (four lines)
or clock-synchronous operation (three lines)
Capable of handling serial transfer as a master or slave
 Data formats
Switching between MSB first and LSB first
The number of bits in each transfer can be changed to any number of bits from 8 to 16, or
to 20, 24, or 32 bits.
128-bit buffers for transmission and reception
Up to four frames can be transmitted or received in a single transfer operation (with each
frame having up to 32 bits)
 Buffered structure
Double buffers for both transmission and reception
