PIC16F1765-E/SL Übersicht
A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (Flash, RAM, EEPROM), and programmable I/O peripherals on one die. Within the broader semiconductor hierarchy, MCUs belong to integrated circuits, sit under microcontrollers, and form the foundation of embedded systems in everything from household appliances to industrial controllers. The PIC16F1765 specifically is an 8-bit MCU - its CPU datapath and registers are 8 bits wide, which is sufficient for control-oriented applications where cost, deterministic behavior, and ease of programming outweigh the need for high arithmetic throughput. Microchip's eXtreme Low Power (XLP) technology is also embedded in this family, enabling sleep currents suitable for battery-powered designs.
Key features include a 10-bit Analog-to-Digital Converter (ADC), a 10-bit Digital-to-Analog Converter (DAC), up to three operational amplifiers, three Configurable Logic Cells (CLC), Peripheral Pin Select (PPS) for flexible signal routing, 10/16-bit PWMs with complementary outputs, a zero-cross detect module, and high-current I/O capable of directly driving LEDs or relays without external transistors. The device operates across -40C to +125C industrial temperature range.
The PIC16F1765 is built on Microchip's enhanced mid-range 8-bit core architecture with a 14-bit instruction word and a 32MHz maximum clock, delivering up to 8 MIPS of computational throughput. Its intelligent analog integration combines traditional digital MCU peripherals with operational amplifiers and a DAC on-chip, reducing external component count and PCB area for sensor-conditioning, signal-generation, and mixed-signal control designs.
Typical applications include LED lighting drivers, switched-mode power supply (SMPS) control, battery chargers, fan/motor control, sensor signal conditioning, and consumer white goods. The combination of op amps, DAC, CLC, and ZCD on a single die makes it especially well-suited to closed-loop analog control without external op-amp ICs.
When designing with the PIC16F1765, note that the 14-pin SOIC (SL) variant has fewer I/O than the 20-pin QFN/P-DIP options; engineers needing additional pins should consider the PIC16F1768 or PIC16F1769 in 20-pin packages. Decoupling capacitors (100 nF + 10 uF) should be placed within a few millimeters of VDD/AVDD/VSS/AVSS pins.

Typische Anwendungen
PIC16F1765-E/SL ist geeignet für 6 Anwendungs: LED Lighting Drivers, Switched-Mode Power Supply (SMPS) Control, Battery Chargers, Fan and Motor Control, Sensor Signal Conditioning, Consumer White Goods.
LED Lighting Drivers
The PIC16F1765-E/SL fits LED lighting drivers because of its 10/16-bit PWM with complementary outputs, 100 mA high-current I/O that can directly drive LED strings, and on-chip op amps for current-sensing feedback loops. The 10-bit DAC sets dimming targets digitally while three CLC cells implement zero-crossing PWM blanking without CPU overhead. The 32 MHz CPU runs 8 MIPS - enough for closed-loop PID brightness control at 1 kHz update rate. Its 1.8-5.5V operating range supports both 3.3V logic LED panels and 5V high-brightness fixtures. The 14-SOIC footprint is small enough for GU10 bulb replacement PCBs. For larger multi-channel LED matrices, the 20-pin PIC16F1769 is preferred for its extra PWM channels.

Switched-Mode Power Supply (SMPS) Control
In SMPS primary-side or secondary-side control, the PIC16F1765-E/SL brings the Zero-Cross Detect (ZCD) peripheral to detect transformer flux-zero-crossings for boundary-conduction-mode PFC and quasi-resonant flyback converters. The on-chip 10-bit ADC samples the feedback voltage and current, while three CLC cells implement hardware-based propagation-delay compensation. The 32 MHz / 8 MIPS core runs the digital compensator at 100 kHz loop bandwidth. Its -40C to +125C extended grade and 14-SOIC footprint suit industrial DIN-rail power modules. For higher-power designs requiring more ADC channels, the PIC16F1769 20-pin variant is recommended.
Empfohlen
Battery Chargers
The PIC16F1765-E/SL is well suited for battery charging applications where the on-chip op amp measures charge current via a sense resistor, the 10-bit DAC programs the CV/CC reference voltages, and the 10-bit ADC monitors battery temperature through an NTC divider. Microchip's XLP technology keeps sleep current low for always-on battery monitors. The three CLCs can implement hardware over-current protection independent of CPU latency. The 1.8-5.5V range directly interfaces 1S Li-Ion or 2-3 AA cells. Engineers building higher-cell-count chargers should consider the 20-pin PIC16F1718.
Empfohlen
Fan and Motor Control
The PIC16F1765-E/SL drives BLDC or brushed-DC fan motors through its complementary 10/16-bit PWM and 100 mA high-current I/O, which can directly switch half-bridge gate drivers or small MOSFETs. The zero-cross detect senses back-EMF zero crossings for sensorless BLDC commutation, while on-chip op amps condition the current-sense signal. Three CLC cells implement hardware commutation timing independent of CPU interrupts, reducing jitter. Its -40C to +125C temperature range supports under-hood automotive fans or industrial blowers. For sensorless FOC, an 8-bit MCU is borderline; consider the dsPIC33 family for that workload.
Empfohlen
Sensor Signal Conditioning
The PIC16F1765-E/SL integrates three on-chip operational amplifiers that buffer and amplify signals from thermocouples, photodiodes, or bridge pressure sensors directly at the MCU, eliminating external op-amp ICs. The 10-bit ADC digitizes the conditioned signals, while the 10-bit DAC can generate programmable excitation voltages or 4-20 mA loop currents. PPS routes analog and digital peripherals to any pin, simplifying PCB layout in space-constrained sensor transmitter designs. Its 1.8-5.5V range is compatible with loop-powered 4-20 mA industrial transmitters. Engineers designing multi-channel sensor hubs should consider the 20-pin PIC16F1769 for more ADC inputs.
Empfohlen
Consumer White Goods
The PIC16F1765-E/SL fits cost-sensitive consumer appliances - coffee machines, washing machines, microwave ovens, rice cookers - where its on-chip op amps read temperature sensors (NTC), its 10-bit ADC monitors water level, and its 100 mA high-current I/O drives relays, buzzers, and seven-segment displays directly without transistor drivers. Three CLCs implement user-interface debouncing and zero-crossing triac firing without CPU load. The -40C to +125C extended grade handles oven-cabinet and outdoor installations. The 14-SOIC package is small enough for compact appliance control boards. For touch-key interfaces, consider the PIC16F15224 with CTMU peripheral.

Wichtigste Unterscheidungsmerkmale
- Integrated zero-cross detect (ZCD) and three CLC cells (vs. PIC16F1615-I/SL)
- Three on-chip operational amplifiers vs zero on many peers (vs. PIC16F1708-E/SO)
- 100 mA high-current I/O for direct LED/relay drive (vs. PIC16F1713-E/SS)
Designhinweise
Place a 100 nF decoupling capacitor within 3 mm of the VDD pin and a bulk 10 uF tantalum or ceramic on the same board net. The PIC16F1765-E/SL has separate AVDD/AVSS pins internally bonded to VDD/VSS on 14-pin SOIC, so use a single decoupling network and a ferrite bead if analog accuracy is critical. Add a 10 kohm pull-up to MCLR/RA3 to prevent spurious resets during power-up; Microchip recommends a 10 kohm pull-up and 100 nF cap on MCLR for production designs.
At maximum 32 MHz CPU clock and full peripheral activity, the PIC16F1765-E/SL dissipates well under 100 mW. The 14-SOIC package has a theta_JA around 100 C/W (estimated: 4-layer JEDEC test board, still air), so no heatsink is required for any combination of 1.8-5.5V supply and -40C to +125C ambient. For continuous 100 mA high-current I/O sourcing into LEDs, total power dissipation may approach 200 mW at 5V - still within safe thermal limits but verify the actual PCB copper area.
Route the ICSP programming pins (RA0/ICSPCLK, RA1/ICSPDAT) directly to a 5-pin header on the PCB edge - never share these traces with high-current signals. Keep analog traces from the on-chip op amp inputs short and guarded by ground traces to avoid digital crosstalk. The 14-SOIC land pattern should use 0.8 mm pitch hand-soldering-compatible pads with 0.5 mm drill for any rework test points.
Do not assume all three op amps are simultaneously usable on the 14-SOIC variant - the pin count may share op-amp outputs with general-purpose I/O, requiring trade-offs via PPS. Always reconfigure PPS after entering sleep mode if peripherals must continue operating. When migrating code from PIC16F1769 (20-pin) to PIC16F1765 (14-pin), verify that the I/O assignment is achievable on the smaller package - some peripheral combinations require 20-pin variants.
