Features

■ 32-bit RXv3 CPU core

? Maximum operating frequency: 240 MHz

Capable of 1396 CoreMark in operation at 240 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

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

? Four low-power modes

■ On-chip code flash memory

? Supports versions with up to 4 Mbytes of ROM

? No wait cycles at up to 120 MHz or when the ROM cache is hit,

one-wait state at above 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.

■ On-chip data flash memory

? 32 Kbytes, reprogrammable up to 100,000 times

? Programming/erasing as background operations (BGOs)

■ On-chip SRAM

? 1 Mbyte of SRAM (no wait states; however, if ICLK is at a

frequency above 120 MHz, access to locations in the 512 Kbytes of

SRAM from 0080 0000h to 0087 FFFFh requires one cycle of

waiting)

? 32 Kbytes of RAM with ECC (single error correction/double error

detection)

? 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: 3 channels

■ 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

? PLL for specific purposes

? 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 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.
