Features

■ 32-bit RX CPU core

? Max. operating frequency: 100 MHz

Capable of 165 DMIPS in operation at 100 MHz

? Single precision 32-bit IEEE-754 floating point

? Two types of multiply-and-accumulation unit (between memories

and between registers)

? 32-bit multiplier (fastest instruction execution takes one CPU clock

cycle)

? Divider (fastest instruction execution takes two CPU clock cycles)

? Fast interrupt

? CISC Harvard architecture with 5-stage pipeline

? Variable-length instructions: Ultra-compact code

? Supports the memory protection unit (MPU)

? Two types of debugging interfaces: JTAG and FINE (two-line)

■ Low-power design and architecture

? Single 3.3-V supply or single 5-V supply; 3.3-V products can be

used with a 5-V analog power supply

? Four low-power modes

■ On-chip main flash memory, no wait states

? 100-MHz operation, 10-ns read cycle (no wait states)

? Programming/erasing as background operations (BGOs)

■ On-chip SRAM, no wait states

? Max. 48 Kbytes

? For instructions and operands

■ DMA

? DMA: Incorporates four channels

? Oscillation-stop detection, frequency measurement, CRC, IWDT,

self-diagnostic function for the A/D converter, etc.

■ External address space

? 4 CS areas (4 × 1 Mbyte)

? Multiplexed address data or separate address lines are selectable per

area.

? 8- or 16-bit bus space is selectable per area.

■ Up to 11 communications interfaces

? CAN (compliant with ISO11898-1), incorporating 32 mailboxes (1

channel)

? SCI with multiple functionalities (5 channels)

Choose from among asynchronous mode, clock-synchronous mode,

smart-card interface mode, simple SPI, simple I2C, and extended

serial mode.

? I2C bus interface for SMBus (2 channels)

? RSPI for high-speed transfer (2 channels)

■ Up to twenty 16-bit timers

? 16-bit MTU3: 100-MHz operation, input capture, output compare,

three-phase complementary PWM waveform output (2 channels),

phase-counting mode (8 channels); complementary PWM does not

burden the CPU.

? 16-bit GPT: 100-MHz operation, input capture, output compare, 4-

channel single-phase complementary PWM waveform output or 1-

channel three-phase complementary + 1-channel single-phase

complementary output, interlocking with comparator (counter

operation, PWM negation control), detection of abnormal oscillation

frequencies (useful for IEC60730 compliance)

(8 channels); complementary PWM does not burden the CPU.

? 16-bit CMT (4 channels)

■ Generation of delays in PWM waveforms (for

products with the product ID code 1)

? The timing with which signals on the 16-bit GPT PWM output pin

rise and fall can be controlled with an accuracy of up to 312 ps (in

operation at 100 MHz).

■ Two A/D converters for 1-MHz operation, total of 8

channels

? Simultaneous sampling on 7 channels is possible with three units.
