PIC16F1765T-I/ST Обзор
Key features of the PIC16F1765T-I/ST include a 10-bit ADC, 10-bit DAC, integrated op amps, zero-cross detect, high-current I/O pins, and the XLP nanoWatt sleep modes that extend battery life. The device operates from 2.3V to 5.5V across the industrial temperature range (-40C to +85C) and provides 12 I/O pins for interfacing with sensors, switches, and actuators.
The PIC16F1765T-I/ST uses Microchip's enhanced mid-range 8-bit core with a hardware multiplier and a 32 MHz oscillator (8 MIPS instruction throughput). It integrates Core Independent Peripherals (CIPs) such as Configurable Logic Cells (CLC), Complementary Waveform Generator (CWG), Numerically Controlled Oscillator (NCO), and signal measurement timers, allowing complex control loops without burdening the CPU. The TSSOP-14 package offers a compact footprint for space-constrained designs.
Typical applications include LED lighting control (constant current drivers, dimming via PWM and zero-cross detection), capacitive-touch user interfaces, sensor signal conditioning using the on-board op amp, battery-powered IoT sensor nodes exploiting the XLP low-power modes, and small motor/solenoid control via the complementary waveform generator. The combination of analog and digital integration makes the part well suited to mixed-signal embedded designs.
When designing with this part, ensure decoupling capacitors are placed close to VDD/VSS, route the high-current I/O traces with sufficient copper to handle their rated sink/source, and use the ICSP programming interface for in-circuit firmware updates. Verify the latest errata and Config Word settings from the Microchip datasheet before committing to layout.

Типичное применение
PIC16F1765T-I/ST подходит для 6 применениеs: LED Lighting Control, Capacitive Touch User Interface, Sensor Signal Conditioning, Battery-Powered IoT Sensor Nodes, Small Motor and Solenoid Control, Smart Home and Appliance Control.
LED Lighting Control
The PIC16F1765T-I/ST suits LED lighting designs because its integrated 10-bit DAC sets a programmable constant-current reference for the driver FET while the CWG generates complementary PWM with programmable dead-band. Zero-cross detect enables direct TRIAC-based phase-cut dimming without external circuitry, and the XLP nanoWatt sleep modes keep standby power in the microamp range for emergency luminaires. At 32 MHz / 8 MIPS the CPU has ample headroom for color-mixing algorithms or DALI protocol stacks.
Рекомендуется
Capacitive Touch User Interface
The PIC16F1765T-I/ST powers capacitive-touch keypads and sliders by combining its mTouch peripheral, 10-bit ADC for proximity sensing, and Configurable Logic Cells for hardware-debounced scanning. The 32 MHz core handles real-time gesture decoding while XLP modes minimize current draw between touches, extending coin-cell battery life. A typical 8-button keypad operates at less than 5 microamps average, making the part ideal for sealed-key appliances and IoT controls.
Рекомендуется
Sensor Signal Conditioning
On-chip op amps and a 10-bit ADC let the PIC16F1765T-I/ST condition and digitize bridge, thermocouple, or photodiode signals without external analog ICs, reducing BOM cost. The 10-bit DAC provides offset or excitation trim, while the CWG can drive a synchronous modulator for chopper-stabilized front-ends. Its 2.3V minimum supply supports single-cell Li-ion or 3V coin-cell operation across the full industrial temperature range.
Рекомендуется
Battery-Powered IoT Sensor Nodes
The PIC16F1765T-I/ST enables long-life battery sensor nodes by combining XLP sleep modes drawing under 50 nA with periodic wake-and-measure cycles using the ADC and op amp for sensor excitation. Its 14 KB program memory holds modest protocol stacks (BLE beacon shaping, LoRaWAN-like duty cycling, proprietary RF) while 1 KB RAM buffers burst data. With 12 I/O and 5.5V tolerance, it interfaces to multiple sensors and a low-power radio module.
Рекомендуется
Small Motor and Solenoid Control
The PIC16F1765T-I/ST drives small brushed DC motors, solenoids, and valve actuators through its high-current I/O (capable of 100 mA source/sink) and Complementary Waveform Generator, which produces programmable dead-band MOSFET drive signals. The 10-bit DAC supplies a closed-loop reference while the op amp reads shunt current for peak-current limiting. Back-EMF zero-cross detection aids in synchronous rectification for higher efficiency.
Рекомендуется
Smart Home and Appliance Control
Within smart-home appliances the PIC16F1765T-I/ST functions as the user-interface and sensor-hub MCU, processing capacitive touch, rotary encoders, and temperature inputs while driving TRIAC-controlled loads via zero-cross detect. The 14 KB Flash accommodates custom firmware, OTA bootloaders, and BLE beacon templates, and 1 KB RAM supports display buffering. Its 2.3V to 5.5V range simplifies power-tree design in line-voltage appliances.

Заметки по проектированию
Decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of the VDD/VSS pins; a bulk 1 uF to 10 uF tantalum or ceramic near the regulator output reduces supply sag during CWG switching events. For battery-powered designs, use the XLP sleep modes (typical 50 nA) and verify the wake-up source is properly debounced in firmware.
Route the high-current I/O traces with at least 0.5 mm trace width or copper pours rated for the expected sink/source current (up to 100 mA per pin). Keep analog-input traces short and shielded with a ground guard ring to minimize noise coupling into the ADC. Place the ICSP connector (RA0/RA1) so that in-circuit programming is accessible without removing the device from board.
Do not exceed 5.5 V on any I/O pin; the absolute-maximum VDD rating is 6.5 V. Always configure unused I/O as outputs driving low (never leave them floating or set to analog input). Verify the Config Word settings (FOSC, WDTE, LVP, etc.) before locking the device - an incorrect FOSC can prevent the part from clocking up at first power-on.
When using the CWG to drive external MOSFETs, place gate-drive traces short and matched; add a small series gate resistor (10 to 47 ohm) to damp ringing. For op-amp circuits, provide proper bias-current return paths and bypass the non-inverting input with a short trace to ground; the integrated op amp input offset is typically <5 mV per datasheet curves.
