PIC16F1716-I/SS Overview
A microcontroller (MCU) is a single-chip computer containing a CPU, memory, and peripherals designed for embedded control. The PIC16F1716 belongs to the 8-bit MCU category, which uses an 8-bit data path. Within the broader semiconductor taxonomy, 8-bit MCUs sit under microcontrollers, then embedded processors, then integrated circuits. The 8-bit class remains dominant in cost-sensitive, low-power applications because of its small code footprint, deterministic interrupt latency, and decades of mature tool support.
Key features include two on-chip operational amplifiers, two high-speed comparators, a 10-bit ADC with up to 28 channels, a 5-bit/8-bit DAC, Core Independent Peripherals (CLC, COG, NCO, Zero Cross Detect), and Peripheral Pin Select (PPS) for flexible signal routing. The XLP technology delivers nanoWatt sleep currents below 50 nA typical in deep sleep, enabling battery-powered designs to operate for years on a single cell.
The architecture is built on Microchip's enhanced mid-range x14 instruction set, providing 200 ns instruction execution at 32 MHz, 49 instructions, and 14-bit-wide instruction words. This balance of code density and computational throughput suits mixed-signal sensor conditioning, closed-loop control loops, and human-machine interface tasks.
Typical applications include industrial sensor conditioning, IoT edge nodes, low-power metering, building automation, motor control signal chains, and consumer white goods. The integrated op amps and comparators allow direct interface with bridge sensors, photodiodes, and thermistors without external analog front-end components.
When designing with this device, allocate careful PCB layout around the analog inputs, keep analog and digital ground returns separated, and verify PPS remapping against your chosen peripheral set in MPLAB X IDE. The XLP sleep modes also require explicit clock-source configuration on wake-up to maintain firmware timing.

Typical Applications
PIC16F1716-I/SS is suitable for 6 applications: Industrial Sensor Conditioning, Battery-Powered IoT Edge Node, Low-Power Metering and Energy Monitoring, Motor Control Signal Chain, Building Automation / HVAC, Consumer White Goods Appliance Control.
Industrial Sensor Conditioning
The PIC16F1716-I/SS is well matched to industrial sensor conditioning because its two on-chip op amps, two high-speed comparators, and 10-bit ADC with up to 28 channels handle bridge sensors, RTDs, and photodiodes without external analog front-end. The 32 MHz enhanced mid-range core executes 8 MIPS while CLC, COG, and NCO peripherals run independently, freeing the CPU for comms and calibration. With XLP deep-sleep current below 50 nA, the MCU can be left always-on in 4-20 mA loops while drawing negligible current. Place the device on a board with separate AGND/DGND return paths, use the internal op amps as instrumentation buffers, and configure PPS to route comparator outputs to the timer capture input.
Recommended
Battery-Powered IoT Edge Node
The PIC16F1716-I/SS targets battery-powered IoT edge nodes thanks to XLP eXtreme Low Power technology with deep-sleep current below 50 nA. Its 14 KB Flash holds 8K instruction words, enough for sensor sampling, edge averaging, and a simple wireless protocol stack. The 1 KB RAM accommodates 4-byte floating-point buffers for ADC readings and time-stamped telemetry queues. The MCU wakes on RTC, samples the ADC, computes a moving average with the DMA-free CLC block, transmits, and returns to sleep - typical duty cycles of 0.1% yield multi-year battery life on a single CR2032. Use PPS to remap UART TX to any digital pin, and rely on internal 32 MHz oscillator for low BOM cost.
Recommended
Low-Power Metering and Energy Monitoring
The PIC16F1716-I/SS suits low-power metering applications where its 10-bit ADC samples current shunts and voltage dividers at 100 ksps while on-chip comparators detect zero-cross events for AC line measurement. Core Independent Peripherals like the COG (Complementary Output Generator) and NCO (Numerically Controlled Oscillator) drive PWM dimming and frequency synthesis without CPU load. The 32 MHz execution rate combined with single-cycle 14-bit instructions provides deterministic timing for billing-grade measurements. With its XLP architecture, the device can operate a smart meter for 10+ years on the meter's own harvested power. Pair with an external tamper-detection EEPROM via I2C for full metering compliance.
Recommended
Motor Control Signal Chain
The PIC16F1716-I/SS supports small DC and stepper motor control loops via its on-chip op amps (for current sensing), high-speed comparators (for back-EMF zero crossing), and COG peripheral (for synchronous MOSFET drive). At 32 MHz the enhanced mid-range core can execute a 1 kHz PID loop with margin for I2C feedback to a host controller. The 14 KB Flash accommodates sensored and sensorless commutation tables, while 1 KB RAM holds the commutation state machine. PPS lets the designer route PWM to any pin, simplifying PCB layout when MOSFET bridges require specific pin assignments. Use the internal 32 MHz oscillator for development and an external crystal for production timing accuracy.
Recommended
Building Automation / HVAC
The PIC16F1716-I/SS fits building automation HVAC nodes where its 28-SSOP footprint mounts on small sensor PCBs that combine temperature, humidity, and CO2 inputs. The two op amps condition thermistor bridges, the ADC digitizes them at 10-bit resolution, and the comparators handle HVAC relay feedback without external glue logic. CLC peripherals implement hysteresis and debounce in hardware, reducing firmware overhead. With XLP deep sleep below 50 nA, the MCU survives years on a coin cell while running HVAC wireless mesh protocols. The 28-pin count provides ample I/O for additional gas sensor interfaces, LCD segment drivers, and user pushbuttons.
Recommended
Consumer White Goods Appliance Control
The PIC16F1716-I/SS is appropriate for consumer appliance controls like washing machines, dishwashers, and small kitchen devices. Its 32 MHz execution rate supports user-interface HMI tasks (LED scan, button debounce, buzzer PWM) on top of motor-control loops. The on-chip op amps handle load-cell weight sensing, water-level detection, and temperature monitoring with one IC. PPS routes UART to either the main board connector or a service-mode test pad without board rework. The industrial -40C to +85C temperature range suits under-cabinet installations. According to Microchip documentation, the device is also suitable for IEC 60730 Class B safety compliance via its built-in CRC and WDT peripherals.

Key Differentiators
- Largest Flash in 28-SSOP across PIC16F170x/171x entry-tier family (vs PIC16F1713-I/SS)
- Two on-chip op amps and 28-channel ADC eliminate external analog front-end (vs PIC16F1518-I/SS)
- Same-family upgrade path to 14 KB Flash newer core via PIC16F15355T-I/SS (vs PIC16F15355T-I/SS)
Design Notes
Use a star-ground pattern with the PIC16F1716-I/SS VSS pin tied to a single analog/digital ground plane. Place a 0.1 uF ceramic decoupling capacitor within 5 mm of each VDD pin and a 10 uF bulk capacitor on the VDDIO2 rail. Keep analog input traces short and guarded by AGND traces to minimize ADC crosstalk on the 28-SSOP footprint.
For XLP deep-sleep operation, verify all unused I/O pins are configured as outputs low (or inputs with internal weak pull-ups disabled). Configure the PPS to remap peripheral functions only after waking, since retaining remaps across sleep is not always reliable on older silicon revisions. Use the SOSC crystal on RC0/RC1 for accurate RTC-based wake intervals.
The PIC16F1716-I/SS includes two on-chip op amps but their inputs are shared with ADC channels. When configuring both, the op amp output is not internally routed to the ADC - you must connect external traces. Configuring PPS incorrectly can cause the COG/NCO to drive peripheral logic that conflicts with capture/compare modules, so verify configuration in MPLAB X with the simulator.
Compliance Information
RoHS and REACH compliant per Microchip product page. Standard industrial -40C to +85C grade (I-suffix); not AEC-Q100 qualified - choose PIC16F1716-E/SS extended grade or automotive-qualified PIC16F1716T-I/SSVAO for vehicle applications.
