特性 Features

■ 32-bit RX CPU core

 32 MHz maximum operating frequency

Capable of 50 DMIPS when operating at 32 MHz

 Accumulator handles 64-bit results (for a single

instruction) from 32-bit × 32-bit operations

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

operations (multiplication instructions take one CPU clock cycle)

 Fast interrupt

 CISC Harvard architecture with five-stage pipeline

 Variable-length instruction format, ultra-compact code

 On-chip debugging circuit

■ Low power consumption functions

 Operation from a single 1.8 to 3.6 V supply

 Three low power consumption modes

 Supply current

High-speed operating mode: 0.11 mA/MHz

Software standby mode: 0.44 μA

 Recovery time from software standby mode: 4.8 μs

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

 Operation at 32 MHz, read cycle of 31.25 ns

 No wait states for reading at full CPU speed

 16 to 512 Kbyte capacities

 Programmable at 1.8 V

 For instructions and operands

■ On-chip data flash memory

 8 Kbytes

1,000,000 Erase/Write cycles (typ.)

 BGO (Background Operation)

■ On-chip SRAM, no wait states

 8 to 64 Kbyte capacities

■ Data transfer controller (DTC)

 Four transfer modes

 Transfer can be set for each interrupt source.

■ Event link controller (ELC)

 Module operation can be initiated by event signals without

going through interrupts.

 Link operation between modules is possible while the CPU is sleeping.

■ Reset and power supply voltage management

 Six types including Power-On Reset (POR)

 Low voltage detection (LVD) with voltage settings

■ Clock functions

 External clock input frequency: Up to 20 MHz

 Main clock oscillator frequency: 1 to 20 MHz

 Sub-clock oscillator frequency: 32.768 kHz

 PLL circuit input: 4 to 8 MHz

 Low-speed on-chip oscillator: 4 MHz

 High-speed on-chip oscillator: 32 MHz±1 (20 to 85°C)

 IWDT-dedicated on-chip oscillator: 15 kHz

 Generate a dedicated 32.768-kHz clock for the RTC

 On-chip clock frequency accuracy measurement circuit (CAC)

■ Realtime clock (RTC)

 30-second, leap year, and error adjustment functions

 Calendar count mode or binary count mode selectable

 Capable of initiating exit from software standby mode
