PIC16F1787-I/P Overview
An 8-bit microcontroller (MCU) is a single-chip computer that combines an 8-bit CPU core, program memory (Flash), data memory (RAM), non-volatile storage (EEPROM), and a rich set of peripherals such as timers, communication interfaces, and analog blocks. PIC16F microcontrollers sit in the hierarchy: MCU -> 8-bit MCU -> PIC16 enhanced mid-range -> PIC16F1xxx family, optimized for low-power, mixed-signal embedded control in cost-sensitive applications.
Key features of the PIC16F1787-I/P include a 32 MHz internal oscillator (8 MIPS), a wide operating voltage range of 1.8V to 5.5V, eXtreme Low Power (XLP) sleep modes, and four op-amps configurable as amplifiers or comparators. The integrated PSMC peripheral provides high-resolution PWM with dead-band control, suitable for motor drive, lighting, and Class-D amplifier stages. Two I2C/SPI and one EUSART interface support a broad range of digital communication.
Typical applications include industrial sensor signal conditioning, LED lighting control with analog dimming, motor control in low-power fans or pumps, battery chargers using the integrated op-amp for current sensing, and consumer appliance control panels. The wide voltage range and XLP modes make the PIC16F1787-I/P well suited for line-powered or battery-powered products.
When designing with this part, place the 0.1uF decoupling capacitor within 5 mm of VDD with a low-ESR path to ground, and configure unused pins as outputs to minimize current consumption. The ICSP programming interface uses the ICSPCLK/ICSPDAT pins, so leave these accessible for in-circuit programming and debugging.

Typical Applications
PIC16F1787-I/P is suitable for 7 applications: Industrial Sensor Signal Conditioning, LED Lighting Control with Analog Dimming, BLDC Motor and Fan Control, Battery Charging and Power Management, Consumer Appliance Control Panels, Class-D Audio Amplifier Control Loops, IoT Edge Sensor Nodes.
Industrial Sensor Signal Conditioning
The PIC16F1787-I/P's four integrated operational amplifiers, 12-bit ADC with 15 channels, and 8-bit DAC create a single-chip analog front end for industrial sensors. The op-amps are configurable as instrumentation amplifiers or active filters around the ADC inputs, eliminating external analog ICs that would otherwise inflate BOM cost and PCB area. At 32 MHz operation the MCU handles 8 MIPS of throughput for linearization, calibration, and HART-style sensor processing.
Recommended
LED Lighting Control with Analog Dimming
The Programmable Switched Mode Controller (PSMC) peripheral delivers high-resolution PWM with dead-band control, enabling smooth LED dimming and color-mixing across multiple channels. The integrated op-amps drive analog current-sense loops to regulate LED current, while the 12-bit ADC monitors photodiode feedback for closed-loop light-level regulation. Operating from 1.8-5.5 V, the same firmware deploys across 3.3 V and 5 V lighting rails.
Recommended
BLDC Motor and Fan Control
The PSMC peripheral provides complementary PWM outputs with programmable dead-band timing, which is critical for driving three-phase BLDC motor half-bridges without shoot-through. Combined with the fast comparators for BEMF sensing and the 32 MHz CPU (8 MIPS) for sensorless control algorithms, the PIC16F1787-I/P enables 16 kHz FOC or trapezoidal commutation in fans, pumps, and small appliances. The 36 I/O pins support Hall-sensor, encoder, and tachometer inputs.
Recommended
Battery Charging and Power Management
The four op-amps on the PIC16F1787-I/P build current-sense amplifiers for Li-ion/LiFePO4 charger control loops, while the 8-bit DAC programs the charge voltage reference. Operating down to 1.8 V supports single-cell battery monitoring with low quiescent current in XLP sleep. Combined with the 14 KB Flash, the MCU runs multi-stage CC-CV charge profiles plus fuel-gauge state machines in a single chip.
Recommended
Consumer Appliance Control Panels
The PIC16F1787-I/P's combination of EUSART, I2C/SPI interfaces, and a generous 14 KB Flash suits white-goods control panels driving keypads, displays, and sensors. The 12-bit ADC reads resistive touch buttons or rotary encoders, while the op-amps buffer thermistor inputs for temperature regulation. Operating up to 5.5 V eliminates the need for additional level shifters when interfacing 5 V displays.
Recommended
Class-D Audio Amplifier Control Loops
The PSMC's high-resolution PWM outputs drive Class-D amplifier half-bridges, while the integrated op-amps serve as feedback error amplifiers in the closed-loop audio path. The 32 MHz CPU bandwidth processes feedback loops at 250 kHz update rates for low THD audio. With 1 KB of RAM the MCU can apply simple audio processing effects such as dynamic bass boost without external DSP ICs.
Recommended
IoT Edge Sensor Nodes
The PIC16F1787-I/P with eXtreme Low Power (XLP) modes achieves under 50 nA sleep current for battery-powered IoT sensor nodes that spend most of their time dormant. The 12-bit ADC reads sensor outputs directly, the op-amps condition analog signals, and the EUSART links to a low-power radio like the MRF89XA for wireless telemetry. The 14 KB Flash hosts TLS-like handshake stubs and over-the-air update bootloaders.

Key Differentiators
- Integrated PSMC peripheral with dead-band timing (vs PIC16F887-I/P)

- XLP deep-sleep under 50 nA (vs PIC16F887-I/P)
Design Notes
Place a 0.1uF low-ESR ceramic decoupling capacitor within 5 mm of each VDD pin (pins 20 and 38) with a direct trace to the nearest VSS ground pin. For VDD core noise above 30 mV, add a 10uF bulk capacitor on the VDD rail. The PIC16F1787-I/P does not require external reset components when MCLR is tied to VDD through a 10k resistor, but always include the ICSP test points on ICSPCLK (RB6) and ICSPDAT (RB7) for in-circuit programming access without removing the MCU.
At maximum 32 MHz clock and 5.5 V supply, the PIC16F1787-I/P core consumes about 7 mA. Power dissipation in the 40-pin PDIP package is well within the 1 W rating at room temperature; however, in enclosed thermal environments above 70C, derate supply current by 50uA per degree Celsius. The integrated op-amps draw additional supply current (200-500 uA each) which must be factored into total thermal budget when all four are active simultaneously.
Route the ICSPCLK and ICSPDAT signals with short traces to test pads on the PCB edge for production programming access. Place the 32.768 kHz secondary oscillator crystal (SOSCO/SOSCI on RC0/RC1) within 5 mm of the MCU with guard traces to GND to reduce noise coupling into low-power Timer1 wakeup events. Keep analog op-amp input traces short and isolated from PWM digital outputs to prevent switching noise injection into the analog signal chain.
Do not drive OPAxOUT pins with external voltages exceeding VDD + 0.3V; this can permanently damage the integrated op-amp output stage. When using the PSMC peripheral, configure dead-band delay in software before enabling PWM outputs to prevent shoot-through in half-bridge drive applications. The MCLR pin (RE3) is input-only and cannot be configured as a general digital output - design PCB layouts that tolerate RE3 floating or pulled high during normal operation.
