Features

• C Compiler Optimized RISC Architecture
• Operating Speed:
  • DC – 64 MHz clock input
  • 62.5 ns minimum instruction cycle
• Multi-Voltage I/O (MVIO):
  • Allows for operation at a voltage domain different than the normal microcontroller operating voltage
  • Provides multiple I/O pins powered by the V_DDIO2 voltage domain
  • Dedicated Low-Voltage Detect circuitry and interrupt for V_DDIO2 domain
  • MVIO pins support a voltage range of 1.62V through 5.5V
• Four Direct Memory Access (DMA) Controllers:
  • Data transfers to SFR/GPR spaces from either the Program Flash Memory, Data EEPROM or SFR/GPR spaces
  • User-programmable source and destination sizes
  • Hardware and software-triggered data transfers
• Vectored Interrupt Capability:
  • Selectable high/low priority
  • Fixed interrupt latency of three instruction cycles
  • Programmable vector table base address
  • Backward compatible with previous interrupt capabilities
• 128-Level Deep Hardware Stack
• Low-Current Power-on Reset (POR)
• Configurable Power-up Timer (PWRT)
• Brown-out Reset (BOR)
• Low-Power BOR (LPBOR) Option
• Windowed Watchdog Timer (WWDT):
  • Watchdog Reset on too long or too short intervals between watchdog clear events
  • Variable prescaler selection
  • Variable window size selection
