• Up to 25 MIPS throughput with 25 MHz clock
• Expanded interrupt handler

Memory

• 768 Bytes internal data RAM (256 + 512)
• 8, 4, or 2 kB byte-programmable EPROM code memory

Digital Peripherals

• 17 Port I/O with high sink current capability
• Hardware enhanced UART, SMBus™, and enhanced SPI™ serial ports
• Four general purpose 16-bit counter/timers
• Timer 3 supports real-time clock using external clock source
• 16-Bit programmable counter array (PCA) with three capture/compare modules and enhanced PWM functionality

Clock Sources

• Two internal oscillators:
  • 24.5 MHz with ±2% accuracy supports crystal-less UART operation and low-power suspend mode with fast wake time
  • 80/40/20/10 kHz low frequency, low power operation
• External oscillator: RC, C, or CMOS Clock
• Can switch between clock sources on-the-fly; useful in power saving modes
