• 10-bit D/A converter provides variable analog output
• Two 32-bit timers/external event counters (with four capture and four compare channels each), PWM unit (six outputs) and watchdog
• Multiple serial interfaces including two UARTs (16C550), two Fast I2C-bus (400 kbit/s), SPI and SSP
• Vectored interrupt controller with configurable priorities and vector addresses
• Up to 47 5V-tolerant general purpose I/O pins
• Up to 9 edge-sensitive or level-sensitive external interrupt pins available
• Power saving modes include Idle and Power-down
• Individual enable/disable of peripheral functions as well as peripheral clock scaling down for additional power optimization
• Single power supply chip with Power On Reset (POR) and Brown Out Detect (BOD) circuits
