PIC16LF1765T-I/ML Overview
A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory (Flash), data memory (RAM), and integrated peripherals such as ADC, DAC, timers, and communication interfaces. The PIC16 architecture is a RISC-based 8-bit core using a 14-bit instruction word optimized for deterministic interrupt response and low power consumption. The PIC16LF1765 belongs to the enhanced mid-range family, supporting peripheral pin select (PPS) for flexible signal routing and XLP (eXtra Low Power) technology for battery-friendly designs.
Key features include 14KB Flash program memory, 1KB RAM, 10-bit ADC, 5-bit and 10-bit DAC, integrated operational amplifiers, zero-cross detect (ZCD) circuitry, programmable ramp generator (PRG), three configurable logic cells (CLC), high-current 100mA I/Os, peripheral pin select (PPS), and 10/16-bit PWM modules. The 16-QFN (4x4) package supports surface-mount designs where board space is constrained, and the high-current I/O pins enable direct LED or driver MOSFET control without external transistors.
Typical applications include LED lighting controllers, sensor signal conditioning, motor control loops, capacitive-touch user interfaces, and battery-powered IoT nodes where the combination of analog integration and low-power operation reduces bill-of-materials cost. The industrial -40C to +85C operating range supports harsh-environment deployments.
Design with this part by leveraging its integrated op amps for analog front-ends and the CLC blocks to implement custom digital logic without external gates. The PPS feature allows peripheral reassignment post-firmware-load, simplifying PCB layout.

Typical Applications
PIC16LF1765T-I/ML is suitable for 6 applications: LED Lighting Controllers, Sensor Signal Conditioning, Battery-Powered IoT Nodes, Motor Control Loops, Capacitive Touch Interfaces, Industrial Control Modules.
LED Lighting Controllers
The PIC16LF1765T-I/ML is well-suited for LED lighting controllers due to its integrated high-current 100mA I/O pins that can directly drive LED strings, eliminating external MOSFET drivers and reducing BOM cost. Its 10/16-bit PWM modules provide smooth dimming resolution for flicker-free operation, while the integrated op amps enable closed-loop current sensing for constant-current regulation. The 1.8V-3.6V operating range suits battery-backed or USB-powered lighting designs. Engineers can use the CLC blocks to implement custom dimming protocols or the zero-cross detect for AC-line synchronization in dimmer applications.
Recommended
Sensor Signal Conditioning
For sensor signal conditioning, the PIC16LF1765T-I/ML integrates three op amps that can implement active filters, instrumentation amplifiers, or transimpedance amplifiers directly on-chip, replacing discrete analog front-ends. The 10-bit ADC with multiple channels supports simultaneous multi-sensor sampling, while the 10-bit DAC enables closed-loop excitation control for bridge sensors like load cells or strain gauges. According to the Microchip datasheet, the integrated op amps include internal configuration for rail-to-rail operation, supporting wide dynamic range sensor outputs within the 1.8V-3.6V supply.
Recommended
Battery-Powered IoT Nodes
The PIC16LF1765T-I/ML is engineered for battery-powered IoT nodes thanks to its XLP (eXtra Low Power) technology and 1.8V-3.6V operating range. Sleep currents below typical IoT thresholds allow months or years of operation from coin-cell batteries. The integrated op amps and DAC eliminate companion analog ICs that would otherwise increase quiescent draw. With 14KB Flash, the device supports over-the-air firmware update logic alongside application code, and the PPS feature allows post-layout peripheral reassignment, enabling compact PCB designs that fit within wearable or sensor-housing form factors.
Recommended
Motor Control Loops
The PIC16LF1765T-I/ML fits small motor control applications including brushed DC and stepper motor drivers in industrial automation. Its high-current 100mA I/O pins can directly switch low-power motor windings, while the integrated op amps handle back-EMF sensing and current feedback. The 10/16-bit PWM modules deliver precise speed and torque control with configurable dead-band generators. The programmable ramp generator (PRG) supports automatic acceleration/deceleration profiles without CPU intervention, freeing the core for communication and supervisory tasks.
Recommended
Capacitive Touch Interfaces
For capacitive touch user interfaces, the PIC16LF1765T-I/ML leverages its integrated op amps and configurable logic cells to implement mTouch capacitive sensing modules without external components. The 10-bit resolution provides reliable touch detection across buttons, sliders, and proximity sensors, while the fast ADC sampling rate supports multi-touch scanning. PPS allows touch electrodes to be routed to almost any I/O pin, simplifying PCB layout. Designers can implement low-power wake-on-touch behavior using sleep mode plus interrupt-driven touch sensing.
Recommended
Industrial Control Modules
The PIC16LF1765T-I/ML serves industrial control modules requiring reliable mixed-signal performance across the -40C to +85C industrial temperature range. Its zero-cross detect (ZCD) peripheral simplifies AC line voltage synchronization for triac-based controls, while the high-current I/O pins drive solid-state relays or opto-isolators directly. Combined with the integrated op amps for transducer interfacing and 10-bit ADC for analog monitoring, the part consolidates multiple discrete functions into a single MCU. Industrial communication protocols such as UART-based Modbus RTU are easily implemented using the on-chip EUSART module.

Key Differentiators
- Highest Flash density in 16-QFN PIC16LF176x family (vs PIC16LF1764-I/ML)
- Three integrated op amps vs fewer on smaller-memory siblings (vs PIC16LF1704T-I/ML)
- Low-voltage XLP variant for battery designs (vs PIC16F1765-I/ML)
Design Notes
The PIC16LF1765T-I/ML operates from 1.8V to 3.6V and supports XLP (eXtra Low Power) modes. For battery-powered designs, configure the BOR (Brown-Out Reset) voltage threshold via configuration bits to match the minimum supply. Place a 100nF decoupling capacitor as close as possible to the VDD pin and a 10uF bulk capacitor on the supply rail. The 'LF' designation means the Flash process requires 1.8V minimum for proper programming, so in-circuit serial programming (ICSP) must respect this lower limit.
The 16-QFN package has a center exposed thermal pad that MUST be soldered to the PCB ground plane for proper thermal dissipation and electrical performance. Use an array of thermal vias under the pad connecting to inner ground layers. Keep analog signal traces short and away from high-current digital outputs to minimize coupling. PPS allows peripheral reassignment post-layout, but route your traces to candidate pins during initial layout to maintain flexibility.
Avoid confusing the PIC16LF1765 with the non-LF PIC16F1765 - the LF variant's max voltage is 3.6V, and exceeding it can damage the Flash programming circuitry. Do not skip the ICSP programming connector on prototypes even if you plan to use pre-programmed parts - field firmware updates often become necessary. When using the integrated op amps, verify the input common-mode range against your signal levels; the rail-to-rail inputs have reduced linearity near the supply rails.
