PIC16F1765T-I/ML Descripción general
An 8-bit microcontroller (MCU) is a single-chip processor based on an 8-bit data bus architecture, typically built around a Harvard or modified-Harvard core such as the Microchip PIC16 enhanced mid-range core. PIC microcontrollers integrate CPU, Flash program memory, SRAM data memory, EEPROM, and a configurable mix of peripherals (ADC, DAC, timers, PWM, comparators, communication interfaces) into one die. The PIC16F176X family sits in Microchip's eXtreme Low Power (XLP) tier and is engineered to combine intelligent analog with digital peripherals for sensor-conditioning, lighting control, and power-conversion feedback loops. As an MCU, it occupies the hierarchy: microcontroller -> embedded processor -> integrated circuit -> semiconductor device.
Key features include 10-bit ADC with multiple channels, a 10-bit DAC, configurable op amps, zero-cross detect, high-current I/O drivers, multiple timers, PWM, configurable logic cells (CLC), and serial interfaces. The device supports industrial temperature operation (-40C to +85C for the -I variant) and is supplied in tape-and-reel packaging (T suffix). It is intended for applications where a balance of low power, integrated analog, and small footprint is required.
The PIC16F1765T-I/ML uses an enhanced mid-range PIC16 core with a 14-bit instruction word, providing deterministic execution and simple assembly/C development. Internal peripherals are interconnected through Microchip's Peripheral Pin Select (PPS) and CLC fabric, allowing analog and digital signals to be routed between blocks without external components.
Typical applications include LED lighting and driver control, sensor signal conditioning, motor control feedback, power-factor correction, zero-cross switching control, and small-form-factor consumer/industrial embedded nodes that need integrated op amps and DACs alongside a small microcontroller core.
Designers should consult the PIC16F176X datasheet and family product page to map pin functions to the specific 16-QFN variant, since the PIC16F176X family is offered in 14- and 20-pin packages and the 16-QFN pinout must be matched against the chosen board layout. Tape-and-reel (-T) and QFN (-ML) suffixes identify the packaging option for high-volume SMT assembly.

Aplicaciones típicas
PIC16F1765T-I/ML es adecuado para 6 aplicacións: LED Lighting and Driver Control, Sensor Signal Conditioning Node, Motor Control Feedback Loop, Power Factor Correction (PFC) Controller, Zero-Cross Switching Control (Solid-State Relay), Compact Consumer/Industrial Embedded Module.
LED Lighting and Driver Control
The PIC16F1765T-I/ML fits LED lighting applications because it integrates zero-cross detect (ZCD), a 10-bit DAC for dimming set-points, configurable op amps for current sensing, and high-current I/O to drive MOSFETs directly. According to the PIC16F176X datasheet, the ZCD peripheral detects AC line zero-crossings without external components, enabling TRIAC or FET dimming while the DAC sets the analog dim target. Placed on the lamp PCB with a small QFN footprint, it replaces an MCU plus external analog ICs, shrinking BOM while keeping flicker-free dim curves.
Recomendado
Sensor Signal Conditioning Node
The PIC16F1765T-I/ML suits compact sensor-conditioning nodes thanks to its integrated configurable op amps, 10-bit ADC, and 10-bit DAC in a 4x4 mm QFN. The on-chip amplifiers drive the sensor bridge and the ADC digitizes the result, while the DAC injects calibration or excitation signals. According to the PIC16F176X datasheet, the CLC fabric can implement hysteresis and digital filtering without external glue logic. Operating at up to 32 MHz lets the core run averaging filters at high sample rates while XLP sleep modes preserve battery life.
Recomendado
Motor Control Feedback Loop
The PIC16F1765T-I/ML works well in low-power BLDC or stepper feedback loops where its op amps can condition back-EMF or current-sense signals and its PWM peripherals drive the power stage. According to the PIC16F176X datasheet, the configurable logic cells (CLC) and high-current I/O reduce external gate-driver complexity for small motors. At 32 MHz the core can service FOC or trapezoidal commutation cycles with margin; the 16-QFN footprint suits compact integrated motor modules.
Recomendado
Power Factor Correction (PFC) Controller
The PIC16F1765T-I/ML fits digital PFC controllers because it combines a 32 MHz core for fast control-loop computation with 10-bit ADC, op amps, and a 10-bit DAC for analog reference generation. According to the PIC16F176X datasheet, the zero-cross detect input can synchronize PFC operation with the AC line and the CLC fabric can implement leading-edge blanking digitally. Its small 16-QFN package enables integration into the PFC stage of an LED driver or compact SMPS reference design.
Recomendado
Zero-Cross Switching Control (Solid-State Relay)
The PIC16F1765T-I/ML is ideal for zero-cross solid-state relay (SSR) controllers because its integrated ZCD peripheral directly senses the AC mains zero-cross point without an external optocoupler or ZCD circuit. According to the PIC16F176X datasheet, the high-current I/O can source enough current to drive a small TRIAC or optotriac directly. The 14 KB Flash supports full SSR timing algorithms plus safety diagnostics while the 16-QFN keeps the SSR module footprint compact.
Recomendado
Compact Consumer/Industrial Embedded Module
The PIC16F1765T-I/ML suits small-footprint general-purpose embedded modules where its integrated analog peripherals reduce BOM while the 8-bit core provides deterministic execution for protocol and control tasks. According to the PIC16F176X datasheet, ICSP support allows in-field firmware updates via standard Microchip programmers, and XLP sleep modes keep idle current low for battery or energy-harvesting nodes. The 16-QFN 4x4 mm footprint suits modules that must fit inside tight enclosures.

Notas de diseño
The 16-QFN (4x4 mm) package exposes a thermal pad (EP) on pin 16 that must be soldered to a sufficiently large copper pour on the PCB. Without a ground pour connected to EP, theta_JA rises sharply and junction temperature can exceed 125C at moderate ambient loads. For designs operating above 25 mA continuous GPIO current or with internal op amps driving heavy loads, allocate at least 100 mm^2 of 1 oz copper to the EP pad to stay within thermal derating. According to the PIC16F176X datasheet, the exposed pad is internally bonded to VSS.
Place decoupling capacitors (typically 100 nF ceramic in parallel with 1-10 uF bulk) as close as possible to the VDD pin (pin 5) and the VSS/EP pad to minimize supply noise. For ADC accuracy in sensor-conditioning applications, route analog signal traces away from PWM outputs and high-current I/O, and add a small RC filter at the ADC input pin. The 16-QFN 4x4 mm footprint requires fine-pitch PCB design - use 0.4 mm pitch traces and 0.2 mm via drill minimum for the breakout of EP pad vias.
Common pitfalls when using PIC16F1765T-I/ML include: (1) forgetting to configure unused I/O as outputs (not inputs) to avoid floating-pin current draw, (2) failing to clear the appropriate PPS register lock sequence before remapping peripheral pins, and (3) confusing the 14-pin, 16-pin, and 20-pin variants of the family - only the 16-QFN matches this part's pinout. Per the PIC16F176X datasheet, the -T suffix means tape-and-reel and -ML is the QFN package designator; other suffixes (e.g., -P for PDIP) refer to different packages.
