Features

■ 32-bit RXv2 CPU core

 Max. operating frequency: 120 MHz

Capable of 240 DMIPS in operation at 120 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

 Operation from a single 2.7- to 3.6-V supply

 Low power consumption: A product that supports all peripheral

functions draws only 0.19 mA/MHz (Typ.).

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

 Four low-power modes

■ On-chip code flash memory

 Supports versions with up to 2 Mbytes of ROM

 No wait cycles at up to 50 MHz or when the ROM cache is hit, one-

wait state at up to 100 MHz, two-wait state at above 100 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, no wait states

 256K/640 Kbytes of SRAM (no wait states)

 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: 1 channel

■ 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
