RX210 Group 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)
I

C bus interface (RIIC)
 1 channel
 Communications formats:
I
2
C 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:

 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*
