Features

■ 32-bit RX CPU core

 Max. operating frequency: 50 MHz

Capable of 78 DMIPS in operation at 50 MHz

 Accumulator handles 64-bit results (for a single

instruction) from 32- × 32-bit operations

 Multiplication and division unit handles 32- × 32-bit

operations (multiplication instructions take one CPU

clock cycle)

 Fast interrupt

 CISC Harvard architecture with 5-stage pipeline

 Variable-length instructions, ultra-compact code

 On-chip debugging circuit

■ Low-power design and architecture

 Operation from a single 1.62- to 5.5-V supply

 1.62-V operation available (at up to 20 MHz)

 Deep software standby mode with RTC remaining usable

 Four low-power modes

■ On-chip flash memory for code, no wait states

 50-MHz operation, 20-ns read cycle

 No wait states for reading at full CPU speed

 128- to 512-Kbyte capacities

 User code programmable via the SCI

 Programmable at 1.62 V

 For instructions and operands

■ On-chip data flash memory

 Eight Kbytes, reprogrammable up to TBD times

 Erasing and programming impose no load on the CPU.

■ On-chip SRAM, no wait states

 20- to 64-Kbyte size capacities

■ DMA

 DMACA: Incorporates four channels

 DTC: Four transfer modes

■ ELC

 Module operation can be initiated by event signals

without going through interrupts.

 Modules can operate while the CPU is sleeping.

■ Reset and supply management

 Nine types of reset, including the power-on reset (POR)

 Low voltage detection (LVD) with voltage settings

■ Clock functions

 Frequency of external clock: Up to 20 MHz

 Frequency of the oscillator for sub-clock generation:

32.768 kHz

 PLL circuit input: 4 to 12.5 MHz

 On-chip low- and high-speed oscillators, dedicated on-

chip low-speed oscillator for the IWDT

 Generation of a dedicated 32.768-kHz clock for the RTC

 Clock frequency accuracy measurement circuit (CAC)

■ Real-time clock

 Adjustment functions (30 seconds, leap year, and error)

 Time capture function

 Time capture on event-signal input through external pins

 RTC capable of initiating return from deep software

standby mode

■ Independent watchdog timer

 125-kHz on-chip low-speed oscillator produces a

dedicated clock signal to drive IWDT operation.

■ Useful functions for IEC60730 compliance

 Self-diagnostic and disconnection-detection functions for

the AD converter, clock-frequency accuracy-

measurement circuit, independent watchdog timer,

functions to assist in RAM testing, etc.

■ Up to nine communications interfaces

 SCI with many useful functions (up to seven interfaces)

 Asynchronous mode, clock synchronous mode, smart

card interface

 I2C bus interface: Transfer at up to 1 Mbps, capable of

SMBus operation (1 interface)

 RSPI (1)

■ External address space

 Four CS areas (4 × 16 Mbytes)

 8- or 16-bit bus space is selectable per area

■ Up to 14 extended-function timers

 16-bit MTU2: input capture, output capture,

complementary PWM output, phase counting mode (6

channels)

 8-bit TMR (4 channels)

 16-bit compare-match timers (4 channels)

■ 12-bit A/D converter

 Capable of conversion within 1 μs

 Sample-and-hold circuits (for three channels)

 Three-channel synchronized sampling available

 Self-diagnostic function and analog input disconnection

detection assistance function

■ 10-bit D/A converter

■ Analog comparator

■ Programmable I/O ports

 5-V tolerant, open drain, input pull-up, switching of

driving ability

■ MPC

 Multiple locations are selectable for I/O pins of

peripheral functions

■ Temperature sensor

■ Operating temp. range

 -40 C to +85C
