Features
RX63N Group products incorporate an Ethernet controller while RX631 Group products do not.
■ 32-bit RX CPU core
Max. operating frequency: 100 MHz Capable of 165 DMIPS in operation at 100 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 (two-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 500 μA/MHz. RTC is capable of operation from a dedicated power supply (min. operating
voltage: 2.3 V). Four low-power modes
■ On-chip main flash memory, no wait states
Supports ROM-less versions and versions with up to 2 Mbytes of ROM (ROMless/256 Kbytes/384 Kbytes/512 Kbytes: RX631 Group only)
100-MHz operation, 10-ns read cycle (no wait states) 768-Kbyte to 2-Mbyte capacities User code is programmable by on-board or off-board programming
■ On-chip data flash memory
ROM-less or 32 Kbytes of ROM (reprogrammable up to 100,000 times) Programming/erasing as background operations (BGOs)
■ On-chip SRAM, no wait states
64 Kbytes/128 Kbytes/192 Kbytes/256 Kbytes of SRAM For instructions and operands Can provide backup on deep software standby
■ DMA
DMAC: Four channels DTC EXDMAC: Two channels Dedicated DMAC for the Ethernet controller: Single channel
■ Reset and supply management
Power-on reset (POR) Low voltage detection (LVD) with voltage settings
■ Clock functions
External crystal oscillator or internal PLL for operation at 4 to 16 MHz Internal 125-kHz LOCO and 50-MHz HOCO 125-kHz clocks for the IWDT
■ Real-time clock
Adjustment functions (30 seconds, leap year, and error) Time capture function
(for capturing times in response to event-signal input on external pins)
■ Independent watchdog timer
125-kHz LOCO clock operation
■ Useful functions for IEC60730 compliance
Oscillation-stoppage detection, frequency measurement, CRC, IWDT, selfdiagnostic function for the A/D converter, etc.
