- 64 or 32 kB Flash; In-system programmable in 512-byte
sectors
Digital Peripherals
- 40/25 Port I/O; All 5 V tolerant with high sink current
- Hardware enhanced SPI™, SMBus™, and one or two
enhanced UART serial ports
- Four 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
