On-chip Low Drop-Out (LDO) voltage regulator, with programmable output user-adjustable
from 2.25 V to 2.75 V
Hibernation module handles the power-up/down 3.3 V sequencing and control for the core
digital logic and analog circuits
Low-power options on controller: Sleep and Deep-sleep modes
Low-power options for peripherals: software controls shutdown of individual peripherals
User-enabled LDO unregulated voltage detection and automatic reset
3.3-V supply brown-out detection and reporting via interrupt or reset
Power-on reset (POR)
Reset pin assertion
Brown-out (BOR) detector alerts to system power drops
Software reset
Watchdog timer reset
Internal low drop-out (LDO) regulator output goes unregulated
Six reset sources
Programmable clock source control
Clock gating to individual peripherals for power savings
IEEE 1149.1-1990 compliant Test Access Port (TAP) controller
Debug access via JTAG and Serial Wire interfaces
Full JTAG boundary scan
Weak pull-up or pull-down resistors
2-mA, 4-mA, and 8-mA pad drive for digital communication; up to four pads can be
configured with an 18-mA pad drive for high-current applications
Slew rate control for the 8-mA drive
Open drain enables
Digital input enables
