32-bit RXv2 CPU core

• Max. operating frequency: 120 MHz

Capable of 240 DMIPS in operation at 120 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)

• JTAG and FINE (one-line) debugging interfaces

■ Low-power design and architecture

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

• Low power consumption: A product that supports all peripheral

functions draws only 0.19 mA/MHz (Typ.).

• RTC is capable of operation from a dedicated power supply.

• Four low-power modes

■ On-chip code flash memory

• Supports versions with up to 2 Mbytes of ROM

• No wait cycles at up to 50 MHz or when the ROM cache is hit, onewait

state at up to 100 MHz, two-wait state at above 100 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.

■ On-chip data flash memory

• 32 Kbytes, reprogrammable up to 100,000 times

• Programming/erasing as background operations (BGOs)

■ On-chip SRAM, no wait states

• 256K/640 Kbytes of SRAM (no wait states)

• 8 Kbytes of standby RAM (backup on deep software standby)

■ Data transfer

• DMACAa: 8 channels

• DTCb: 1 channel

• EXDMAC: 2 channels

• DMAC for the Ethernet controller: 1 channel

■ Reset and supply management

• Power-on reset (POR)

• Low voltage detection (LVD) with voltage settings

■ Clock functions

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

MHz

• 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 function

(for capturing times in response to event-signal input)

■ Independent watchdog timer

• 120-kHz (1/2 LOCO frequency) clock operation

■ 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 can protect values in important

registers against overwriting.
