Description
 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*¹ or output of a "wake-on-LAN" signal (WOL)
 Compliance with flow control as defined in IEEE 802.3x standards
Note 1. Magic PacketTM is a registered trademark of Advanced Micro Devices, Inc.
 Alleviation of CPU loads by the descriptor control method
 Transmission FIFO: 2 Kbytes; Reception FIFO: 2 Kbytes
 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
 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 I²C
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
 4 channels (one of them is FM+)
 Communication formats
I²C bus format/SMBus format
Supports the multi-master
Max. transfer rate: 1 Mbps (channel 0)
 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
 3 channels
 Compliance with the ISO11898-1 specification (standard frame and extended frame)
 32 mailboxes each
 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
