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 de s ig n an d a rch itecture
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 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
(ROM-less version: RX631 Group only)
100-MHz operation, 10-ns read cycle (no wait states)
384-Kbyte to 2-Mbyte capacities
User code programmable via the USB, SCI, or JTAG
■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
32- to 128-Kbyte capacities
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
Dedicated 125-kHz LOCO for the IWDT
■Real-time cl ock
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, self-
diagnostic function for the A/D converter, etc.
■Various communications interfaces
Ethernet MAC (1) (not in RX631 Group products)
Host/function or OTG controller (1) and function controller (1) with full-
speed USB 2.0 transfer
CAN (compliant with ISO11898-1), incorporating 32 mailboxes (up to 3
modules)
SCI with multiple functionalities (up to 13)
Choose from among asynchronous mode, clock-synchronous mode, smart-
card interface mode, simplified SPI, simplified I2C, and extended serial
mode.
I2C bus interface for transfer at up to 1 Mbps (up to 4)
RSPI for high-speed transfer (up to 3)
■External address space
Buses for high-speed data transfer (max. operating frequency of 50 MHz)
8 CS areas (8 × 16 Mbytes)
Multiplexed address data or separate address lines are selectable per area.
8-, 16-, or 32-bit bus space is selectable per area
