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 0.3mA/MHz (Typ.).
• RTC is capable of operation from a dedicated power supply.
• Four low-power modes
◾ On-chip code flash memory, no wait states
• Supports versions with up to 4 Mbytes of ROM
• 120-MHz operation, 8.3-ns read cycle (no wait states)
• User code is programmable by on-board or off-board programming.
• Programming/erasing as background operations (BGOs)
◾ On-chip data flash memory
• 64 Kbytes, reprogrammable up to 100,000 times
• Programming/erasing as background operations (BGOs)
◾ On-chip SRAM
• 512 Kbytes of SRAM (no wait states)
• 32 Kbytes of RAM with ECC (one wait state, 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
