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
Inspect/modify memory and registers
Superior performance to emulation systems using ICE-chips, target
pods, and sockets
Typical Operating Current:7 mA at 25 MHz
Typical Stop Mode Current: <0.1 µA
