Temperature Range: –40 to +85 °C
Small Form Factor
Programmable hysteresis and response time
Configurable to generate interrupts or reset
Low current (0.4 µA)
On-chip debug circuitry facilitates full speed, non-intrusive in-system
debug (no emulator required)
Provides breakpoints, single stepping, watchpoints
Inspect/modify memory, registers, and stack
Superior performance to emulation systems using ICE-chips, target
pods, and sockets
Typical operating current: 5.8 mA at 25 MHz
Typical stop mode current: <0.1 µA
