1. Overview

Communication

functions

Serial communications

interfaces (SCIc, SCId)

 13 channels (channel 0 to 11: SCIc, channel 12: SCId)

 Serial communications modes:

Asynchronous, clock synchronous, and smart-card interface

 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 (SCI5, SCI6, and SCI12)

 Simple IIC

 Simple SPI

 Master/slave mode supported (SCId only)

 Start frame and information frame are included (SCId only)

I2C bus interface (RIIC)

 1 channel

 Communications formats:

I2C bus format/SMBus format

 Master/slave selectable

 Supports the fast mode

Serial peripheral

interface (RSPI)

 1 channel

 Transfer facility

Using the MOSI (master out, slave in), MISO (master in, slave out), SSL (slave select), and RSPI

clock (RSPCK) 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

 Choice of LSB-first or MSB-first transfer

The number of bits in each transfer can be changed to any number of bits from 8 to 16, 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)

 Double buffers for both transmission and reception

12-bit A/D converter (S12ADb)

 12 bits (16 channels  1 unit)

 12-bit resolution

 Minimum conversion time: 1.0 s per channel (in operation with ADCLK at 50 MHz)

 Operating modes

Scan mode (single scan mode, continuous scan mode, and group scan mode)

 Sample-and-hold function

 Self-diagnosis for the A/D converter

 Assistance in detecting disconnected analog inputs

 Double-trigger mode (duplication of A/D conversion data)

 A/D conversion start conditions

A software trigger, a trigger from a timer (MTU), an external trigger signal, or ELC

Temperature sensor (TEMPSa)

 Outputs the voltage that changes depending on the temperature

 PGA gain switchable: Four levels according to the voltage range

D/A converter (DA)

 2 channels

 10-bit resolution

 Output voltage: 0 V to VREFH

CRC calculator (CRC)

 CRC code generation for arbitrary amounts of data in 8-bit units

 Select any of three generating polynomials:

X8 + X2 + X + 1, X16 + X15 + X2 + 1, or X16 + X12 + X5 + 1

 Generation of CRC codes for use with LSB-first or MSB-first communications is selectable.

Comparator A (CMPA)

 2 channels

 Comparison of reference voltage and analog input voltage

Comparator B (CMPB)

 2 channels

 Comparison of reference voltage and analog input voltage

Data Operation Circuit (DOC)

Comparison, addition, and subtraction of 16-bit data

Power supply voltage/Operating frequency

VCC = 1.62 to 1.8 V: 20 MHz, VCC = 1.8 to 2.7 V: 32 MHz, VCC = 2.7 to 5.5 V: 50 MHz

Operating temperature

D version:

40 to +85C, G version: 40 to +105C*2
