1. Overview
Communication
function
USB 2.0 function
module (USBa)
Includes a UDC (USB Device Controller) and transceiver for USB 2.0
Single port
Compliance with the USB 2.0 specification
Transfer rate: Full speed (12 Mbps)
Self-power mode and bus power are selectable
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 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
I2C bus interfaces
(RIIC)
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)
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 (RSPI)
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
12-bit A/D converter (S12ADa)
1 unit (1 unit × 21 channels)
12-bit resolution
Conversion time: 1.0 s per channel (in operation with PCLK at 50 MHz)
Operating mode
Scan mode (single scan mode or continuous scan mode)
Sample-and-hold function
Reference voltage generation
Three ways to start A/D conversion
Conversion can be started by software, a conversion start trigger from a timer (MTU,
TPU, or TMR), or an external trigger signal.
