On-chip debug circuitry facilitates full speed, non-
intrusive in-system debug (no emulator required)
Provides breakpoints, single stepping,
inspect/modify memory and registers
Superior performance to emulation systems using
ICE-chips, target pods, and sockets
Low cost, complete development kit
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
Internal or external start of conversion source
Built-in temperature sensor
Programmable hysteresis and response time
Configurable as interrupt or reset source
Low current
