Line-break generation and detection
Two independent integrated analog comparators
Configurable for output to: drive an output pin or generate an interrupt
Compare external pin input to external pin input or to internal programmable voltage reference
20-41 GPIOs, depending on configuration
5-V-tolerant input/outputs
Programmable interrupt generation as either edge-triggered or level-sensitive
Low interrupt latency; as low as 6 cycles and never more than 12 cycles
Bit masking in both read and write operations through address lines
Pins configured as digital inputs are Schmitt-triggered.
Programmable control for GPIO pad configuration:
•
•
•
•
•
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)
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
