VREGOUT
(2.7-5.25 V)
RST/C2CK
±1 LSB INL; guaranteed monotonic
Programmable throughput up to 200 ksps
Data-dependent windowed interrupt generator
Programmable gain maximizes input signal span
On-chip debug circuitry facilitates full speed, non-intrusive in-system
debug (no emulator required)
Provides breakpoints, single stepping, watch-points
Inspect/modify memory, registers, and stack
Superior performance to emulation systems using ICE-chips, target
pods, and sockets
Typical operating current: 7 mA at 25 MHz at 5.0 V
Multiple power saving sleep and shutdown modes
