Features
■ 32-bit RXv2 CPU core
 Max. operating frequency: 240 MHz
Capable of 480 DMIPS in operation at 240 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
 Single voltage supply: 2.7 to 3.6 V
 Low power consumption: A product that supports all peripheral
functions draws only 0.2mA/MHz (Typ.).
 RTC is capable of operation from a dedicated power supply.
 Four low-power modes
■ On-chip code flash memory
 Up to 4 Mbyte
 No wait states at up to 120 MHz or when the AFU is hit, one wait
state at above 120 MHz and when the AFU is missed
 User code is programmable by on-board or off-board programming.
 Background programming/erasing (BGO:Background operation)
■ On-chip data flash memory
 64 Kbytes, reprogrammable up to 100,000 times
 Background programming/erasing (BGO:Background operation)
■ On-chip SRAM
 512 Kbytes of SRAM (no wait states except in the 256 Kbytes from
0004 0000h to 0007 FFFFh when ICLK is set to 120 MHz or faster)
 32 Kbytes of RAM with ECC (single-error correction and double
error detection)
 8 Kbytes of standby RAM (backup on deep software standby)
■ Data transfer
 DMAC: 8 channels
 DTC
 EXDMAC: 2 channels
 DMAC for the Ethernet controller: 3 channels for 176- and 177-pin
products; 2 channels for 100-, 144-, and 145-pin products
■ 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, CRC,
IWDTa, self-diagnostic function for the A/D converter, etc.
 Register write protection function can protect values in important
registers against overwriting.
