Key Features

Pipelined instruction architecture - Executes 70% of instruction set in 1 or 2 system clocks
Expanded interrupt handler
Two comparators
USB specification 2.0 compliant
Full speed (12Mbps) or low speed (1.5Mbps) operation
Integrated clock recovery - no external crystal required for full speed or low speed
Supports eight flexible endpoints
1kB USB Buffer memory
Integrated transceiver, no external resistors required
On-chip debug circuitry facilitates full speed, non-intrusive in-system debug
Provides breakpoints, single stepping, inspect/modify memory and registers
Superior performance to emulation systems using ICE-chips, target pods and sockets
Hardware enhanced UART, SMBus™ and SPI™ serial ports
Four general purpose 16-bit counter/timers
16-bit Programmable counter array (PCA) with five capture/compare modules
External memory interface (EMIF)
Internal Oscillator - ±0.25% accuracy with clock recovery enabled
External oscillator - Crystal, RC, C or clock (1 or 2 pin modes)
Low frequency (80kHz) Internal oscillator
Can switch between clock sources on-the-fly
