Typical operating current: 19 mA at 50 MHz;

Typical stop mode current: 1 µA

Pipelined instruction architecture; executes 70% of

instructions in 1 or 2 system clocks

Up to 50 MIPS throughput with 50 MHz clock

Expanded interrupt handler

Up to 200 ksps

Up to 32 external single-ended inputs

VREF from on-chip VREF, external pin or V
