PIC16LF1716-I/SP Présentation
A microcontroller (MCU) is a single-chip computer containing a CPU core, non-volatile program memory, volatile data memory, and integrated peripherals. The 8-bit PIC16 family sits at the low-power, low-cost end of Microchip's portfolio and is widely used in general-purpose embedded control. The PIC16LF1716 belongs to the LF "low-voltage / low-power" sub-family, supporting operation down to 1.8 V and featuring eXtreme Low Power (XLP) technology that enables sleep currents in the nanoampere range for battery-friendly designs.
Key features include 14 KB self-programmable Flash, 1 KB SRAM, 10-bit ADC with automated channels, two operational amplifiers suitable for signal conditioning, a 5-bit and 8-bit DAC for setpoint generation, and four Configurable Logic Cells that allow hardware glue logic to be implemented without discrete gates. The PWM, CCP and CWG peripherals support motor and lighting control, while PPS allows digital peripheral pins to be remapped to multiple physical I/O pins.
Typical applications include consumer and IoT battery-powered sensor nodes, intelligent thermostats and HVAC controllers, LED lighting drivers, small appliance control boards, and low-cost analog front-end conditioning where the on-chip op-amps eliminate external amplifiers.
When designing with this device, ensure the ICSP clock and data pins are accessible for in-circuit programming. Add a 100 nF decoupling capacitor close to VDD, keep analog and digital grounds joined at a single point, and use PPS to route peripherals away from noisy traces.

Applications typiques
PIC16LF1716-I/SP convient pour 6 applications: Battery-Powered IoT Sensor Node, Smart Thermostat and HVAC Controller, LED Lighting and Dimmer Control, Small Appliance Control Board, Industrial Analog Front-End Conditioning, Educational and Hobby Embedded Platform.
Battery-Powered IoT Sensor Node
The PIC16LF1716-I/SP suits battery-powered IoT sensor nodes thanks to its 1.8 V minimum supply and XLP nanoamp sleep current. Its 32 MHz core, 14 KB Flash and 1 KB RAM run a duty-cycled sensor stack with on-chip 10-bit ADC converting battery and sensor voltages, while CLC and NCO peripheral logic wake the part on specific events without CPU overhead. Estimated: at 0.1% active duty cycle, average current is below 10 uA, supporting multi-year coin-cell operation. PPS allows signal routing without PCB changes.
Recommandé
Smart Thermostat and HVAC Controller
The PIC16LF1716-I/SP drives smart thermostat control with on-chip op-amps amplifying thermistor or RTD signals into the 10-bit ADC. COG and PWM modules generate the triac-fired signals needed for compressor and fan control, and CLC handles safety interlocks without CPU load. The 14 KB Flash holds state machines, scheduler logic, and a small Wi-Fi command parser. The SPDIP-28 package supports hand-soldered prototypes and educational HVAC kits.
Recommandé
LED Lighting and Dimmer Control
For LED drivers and dimmers, the PIC16LF1716-I/SP uses its 8-bit DAC to set constant-current references and PWM channels to drive MOSFET gates with smooth dimming transitions. Zero Cross Detect (ZCD) detects AC line crossings for phase-angle dimming, while CLC implements the missing-cycle detection. Its 1.8 V capability makes it compatible with low-voltage DC LED strips, and the SPDIP package simplifies bench characterization during lamp prototyping.
Recommandé
Small Appliance Control Board
In small appliances such as coffee makers, slow cookers, or blenders, the PIC16LF1716-I/SP provides motor PWM, sensor conditioning, and user-interface management on a single chip. The on-chip op-amps condition pressure and temperature signals, while the 8-bit DAC generates analog references for power-factor control loops. The CIP suite ensures deterministic response time for safety-critical interlocks, and 14 KB Flash holds firmware upgrades over EUSART bootloaders.
Recommandé
Industrial Analog Front-End Conditioning
Engineers use the PIC16LF1716-I/SP as a low-cost analog front end that conditions 4-20 mA or 0-10 V process signals using its on-chip op-amps before ADC sampling. The CLC peripheral implements Schmitt-style noise filters in hardware, reducing CPU load. PPS lets engineers place digital communication on isolated pins while keeping analog signals on quieter ports, helping meet industrial CE/EMI margins on a tight BOM.
Recommandé
Educational and Hobby Embedded Platform
The PIC16LF1716-I/SP is an excellent teaching platform thanks to the through-hole SPDIP-28 package that fits breadboards and perfboards without soldering adapters. MPLAB X with XC8 and the PICkit 4 programmer provide a free toolchain for student projects covering ADC, op-amp, PWM, and CIP concepts. Universities can use the part to demonstrate low-power embedded design, peripheral pin select, and configurable logic cells in a single lab session.

Principaux différenciateurs
- Largest Flash in LF 16F family at 28-SPDIP pinout (vs PIC16LF1713-I/SP)
- Broader Core Independent Peripheral set than 1619-series (vs PIC16LF1619-I/SS)
- On-chip dual op-amps eliminate external analog ICs (vs PIC16LF1559-I/P)
Notes de conception
Place a 100 nF decoupling capacitor as close as possible to each VDD pin (pins 1 and 20), with a 10 uF bulk capacitor on the main 3.3 V rail. The PIC16LF1716 LF variant operates down to 1.8 V, so verify the regulator's dropout at peak loads of around 15 mA. XLP sleep currents can reach the nA range only when unused peripherals are gated off in the PMD registers; leave peripherals enabled by default at the cost of higher sleep current.
Keep analog inputs (RA0-RA3, RB1, RB0) routed away from high-speed digital lines such as RC6/RC7 (EUSART) to minimize ADC noise pickup. Use a single-point ground star near VSS pin 8 or pin 15, with separate analog and digital ground planes tied at that point. For the SPDIP-28 package, leave 0.1 inch row spacing to maintain breadboard compatibility during prototyping.
Do not connect MCLR (pin 4, RA3) directly to VDD without a pull-up resistor, or the ICSP programmer will fail to enter programming mode. The on-chip op-amps are not rail-to-rail input on all revisions; verify input common-mode range against the analog signal swing in the PIC16LF1716 datasheet electrical characteristics table. PPS must be unlocked (PPSLOCK bit cleared) before reassigning peripheral pins and locked afterwards to prevent runaway writes from runaway code.
