• Up to 5.5V output with open drain configuration on

5V tolerant pins with an external pull-up

• 4 mA sink on all I/O pins

On-Chip Flash and SRAM:

• Flash program memory, up to 256 Kbytes

• Data SRAM, up to 30 Kbytes (includes 2 Kbytes

of DMA RAM):

System Management:

• Flexible clock options:

- External, crystal, resonator, internal RC

- Fully integrated PLL

- Extremely low jitter PLL

• Power-up Timer

• Oscillator Start-up Timer/Stabilizer

• Watchdog Timer with its own RC oscillator

• Fail-Safe Clock Monitor

• Reset by multiple sources

Power Management:

• On-chip 2.5V voltage regulator

- 1 timer runs as Real-Time Clock with external

32.768 kHz oscillator

- Programmable prescaler

• Input Capture (up to eight channels):

- Capture on up, down or both edges

- 16-bit capture input functions

- 4-deep FIFO on each capture

• Output Compare (up to eight channels):

- Single or Dual 16-Bit Compare mode
