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.
