- Hardware enhanced SPI™, two I2C/SMBus™, and two
enhanced UART serial ports
- Six general purpose 16-bit counter/timers
- 16-bit programmable counter array (PCA) with five cap-
ture/compare modules
- External Memory Interface (EMIF)
Clock Sources
- Internal Oscillator: ±0.25% accuracy with clock recovery
enabled. Supports all USB and UART modes
- External Oscillator: Crystal, RC, C, or clock (1 or 2 Pin
modes)
- Low Frequency (80 kHz) Internal Oscillator
- Can switch between clock sources on-the-fly
Packages
