■ 32-bit RXv3 CPU core

? Maximum operating frequency: 120 MHz

Capable of 707 CoreMark in operation at 120 MHz

? Double-precision 64-bit IEEE-754 floating point

? A collective register bank save function is available.

? Supports the memory protection unit (MPU)

? JTAG and FINE (one-line) debugging interfaces

■ Low-power design and architecture

? Operation from a single 2.7- to 3.6-V supply

? Battery supply of backup power allows continued operations of the

RTC and the backup registers.

? Four low-power modes

■ On-chip code flash memory

? No wait cycles at up to 60 MHz or when the ROM cache is hit, onewait

state at up to 120 MHz

? User code is programmable by on-board or off-board programming.

? Programming/erasing as background operations (BGOs)

? A dual-bank structure allows exchanging the start-up bank.

? Low voltage detection (LVD) with voltage settings

? Backup domain low power detection

■ Clock functions

? External crystal resonator or internal PLL for operation at 8 to 24

MHz

? A sub-clock oscillator connectable to a 32.768-kHz crystal resonator

? Internal 240-kHz LOCO and HOCO selectable from 16, 18, and 20

MHz

? 120-kHz clock for the IWDTa

■ Real-time clock

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

? Real-time clock counting and binary counting modes are selectable

? Time capture in response to an event-signal input

■ Independent watchdog timer

? Operates with the 120-kHz clock frequency generated by the

dedicated low-speed oscillator

■ Useful functions for IEC60730 compliance

? Oscillation-stoppage detection, frequency measurement, CRCA,

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

? Register write protection function that protects important registers

against overwriting

■ Remote control signal receiver
