Flexible, configurable analog-to-digital conversion
Four programmable sample conversion sequences from one to eight entries long, with
corresponding conversion result FIFOs
Each sequence triggered by software or internal event (timers, analog comparators, or GPIO)
On-chip temperature sensor
One integrated analog comparator
Configurable for output to: drive an output pin, generate an interrupt, or initiate an ADC sample
sequence
Compare external pin input to external pin input or to internal programmable voltage reference
Master and slave receive and transmit operation with transmission speed up to 100 Kbps in
Standard mode and 400 Kbps in Fast mode
Interrupt generation
Master with arbitration and clock synchronization, multimaster support, and 7-bit addressing
mode
5-28 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
Can initiate an ADC sample sequence
Pins configured as digital inputs are Schmitt-triggered.
Programmable control for GPIO pad configuration:
•
•
•
•
•
Weak pull-up or pull-down resistors
2-mA, 4-mA, and 8-mA pad drive for digital communication
Slew rate control for the 8-mA drive
Open drain enables
Digital input enables
