PIC16F1768T-I/ML 概要
An 8-bit flash microcontroller is a single-chip computer that combines a CPU, non-volatile program memory (flash), RAM, and configurable peripherals on one die. The PIC16F1768 belongs to the PIC16 XLP family - 'XLP' stands for 'eXtreme Low Power' and indicates Microchip's nanoWatt XLP technology, which targets battery-operated and energy-harvesting designs where quiescent current directly determines service life. 8-bit MCUs occupy the lower tier of the embedded controller hierarchy below 16-bit and 32-bit Cortex-M devices, but offer the best cost-per-pin ratio for applications that do not require DSP performance or large memory maps.
Key features include 7KB self-programmable flash with up to 100K erase/write cycles, 512 bytes SRAM, an internal 32MHz oscillator accurate to +/-1% across voltage and temperature, four 10-bit PWM modules, two operational amplifiers configurable as unity-gain buffers or inverting/non-inverting amplifiers, a 10-bit DAC with up to 100uA output drive, and zero-cross detect for AC line-signal interfacing. The 20-pin QFN (4x4 mm) package occupies 16 mm2 of PCB area, making it the most compact option in the PIC16F176x family and enabling miniaturized sensor and lighting nodes.
The PIC16F1768 uses a 14-bit instruction-word RISC architecture with a single-cycle ALU, an 8-level hardware stack, and 49 instructions including hardware multiply. The device includes a configurable logic cell (CLC), complementary waveform generator (CWG), and numerically controlled oscillator (NCO) for flexible digital signal generation, reducing the need for external timing components. The peripheral pin select (PPS) allows most digital peripherals to be routed to almost any I/O pin, simplifying PCB layout and reducing routing constraints on compact 20-pin designs.
Typical applications include LED lighting drivers using op-amp-based constant-current control and PWM dimming, sensor signal conditioning with on-chip op amps and DAC for offset/span trim, AC zero-cross detection for triac/SCR control of dimmers and small motor drives, appliance control panels, and IoT edge nodes requiring extended battery life. Industrial segments such as smart metering, building automation, and HVAC actuators also leverage its high-current I/O and integrated analog.
When designing with this MCU, ensure the exposed pad of the QFN-20 is soldered to a copper pour of at least 0.5 cm2 to keep theta_JA within datasheet limits (typically ~35 C/W on a 4-layer JEDEC test board). The internal 32MHz oscillator avoids an external crystal in most applications, freeing the OSC1/OSC2 pins for digital I/O.

主な用途
PIC16F1768T-I/ML の用途: 7 件s: LED Lighting Driver and Dimmer Control, AC Line Zero-Cross Detection and TRIAC Control, Sensor Signal Conditioning and IoT Edge Nodes, Smart Metering and Utility Monitoring, Small Appliance and White-Goods Control, Battery-Operated Portable and Wearable Devices, Building Automation and HVAC Actuator Control.
LED Lighting Driver and Dimmer Control
The PIC16F1768T-I/ML excels in LED lighting designs thanks to its two on-chip operational amplifiers that close the loop on current-sense resistors, its 10-bit DAC with 100 uA output drive for analog dimming trim, and four 10-bit PWM channels for color-mixing or dim ratio control. The complementary waveform generator (CWG) produces non-overlapping gate-drive signals for synchronous buck/boost LED driver topologies, eliminating an external gate-driver IC. With XLP nanoWatt technology, the device draws microamps in sleep, making battery-powered emergency-LED and solar-light designs practical. The 20-pin QFN-20 footprint fits inside a 16 mm2 PCB area, enabling miniaturized MR16/MR11 lamp form factors.

AC Line Zero-Cross Detection and TRIAC Control
The PIC16F1768T-I/ML integrates a dedicated zero-cross detect (ZCD) peripheral that simplifies AC mains interfacing by generating a synchronous interrupt at each line-voltage zero crossing without optocouplers. Combined with the high-current I/O pins that can directly source TRIAC gate pulses, the device implements phase-angle or zero-cross TRIAC dimmers, motor-speed controllers, and solid-state relays in a single chip. The op amps condition line-voltage sense signals, while the 10-bit ADC monitors RMS voltage and current for fault detection. Industrial temperature grade (-40C to +85C) supports appliance and HVAC control environments.
おすすめ
Sensor Signal Conditioning and IoT Edge Nodes
The PIC16F1768T-I/ML functions as a self-contained analog-front-end node by combining two op amps for transducer excitation and gain, a 10-bit DAC for span/offset trim, and a 10-bit ADC for digitization - all within a single 20-pin QFN. The peripheral pin select (PPS) reroutes digital functions to free analog pins, simplifying PCB layout in dense sensor modules. XLP sleep currents below 1 uA extend battery life in wireless IoT edge nodes that wake periodically to read sensors and transmit via companion radio. The hardware multiply and 32MHz core complete PID loops and FFT pre-processing in real time without DSP extensions.
おすすめ
Smart Metering and Utility Monitoring
The PIC16F1768T-I/ML supports single-phase energy-meter designs where its high-current I/O directly drives metrology-LED pulse outputs, op amps amplify shunt-resistor voltage, and the 10-bit ADC samples current and voltage waveforms. The zero-cross detect synchronizes sampling to the AC line for accurate active/reactive power calculation. With 7KB program space and 512 bytes RAM, the device fits basic tariff logic, RTC support, and communication stacks for AMI endpoints. The industrial temperature grade and QFN-20 footprint suit sealed indoor meter enclosures where PCB area is constrained.
おすすめ
Small Appliance and White-Goods Control
The PIC16F1768T-I/ML targets white-goods control panels for coffee machines, microwave ovens, washing machines, and induction cooktops. The CWG module generates complementary drive signals for IGBT or MOSFET half-bridges used in induction heating or inverter compressor drives, while the four 10-bit PWM channels drive user-interface buzzers, displays, and indicator LEDs. The two op amps condition thermistor and pressure-sensor inputs, and the on-chip 10-bit DAC generates analog reference voltages. The 32MHz instruction cycle handles vector-control loops for sensorless BLDC motors in modern appliance designs.
おすすめ
Battery-Operated Portable and Wearable Devices
The PIC16F1768T-I/ML is tailored for coin-cell or Li-Ion battery devices where XLP nanoWatt technology draws less than 1 uA in sleep, extending shelf life and runtime. The 20-pin QFN-20 (4x4 mm) footprint integrates into wearable form factors, hearing aids, and remote-control key fobs. The CLC and NCO peripherals synthesize low-frequency tones, motor-control PWM, or RFID-emulating carrier signals without waking the CPU. The DAC and op amps enable capacitive-touch sensing via analog charge-measurement techniques documented in Microchip application notes.
おすすめ
Building Automation and HVAC Actuator Control
The PIC16F1768T-I/ML serves as a smart actuator node in building automation systems, driving thermal-actuator valves, damper motors, and lighting relays via its high-current I/O. The CWG module produces the dead-time-controlled complementary outputs needed for triac dimmers and synchronous-rectifier HVAC drivers. The op amps read thermistor/resistive temperature sensors for zone control, while the 10-bit ADC digitizes setpoint inputs from analog wall thermostats. The 49-instruction PIC RISC core provides deterministic real-time response under interrupts, a key requirement for HVAC control loops that must complete scans in defined windows.

設計ノート
Estimated: The 20-pin QFN (4x4 mm) package relies on its exposed thermal pad for heat dissipation. Solder the EP to a copper pour of at least 0.5 cm2 on a 4-layer JEDEC test board to keep theta_JA within datasheet limits (approximately 35 C/W). Without proper thermal pad soldering, junction temperature can exceed 125 C under sustained high-current I/O loading and reduce long-term reliability.
Place a 0.1 uF decoupling capacitor as close as possible to the VDD pin (pin 8) with a short trace to the VSS pin (pin 7). Add a bulk 1-10 uF capacitor on the same supply rail near the MCU. The QFN-20 exposed pad must be soldered to a ground pour with a via-fan (7-9 thermal vias to internal ground) per Microchip QFN-layout application notes. Avoid routing analog signals under the EP to minimize noise coupling.
Do not assume the PIC16F1768 and PIC16F1764 are interchangeable on firmware - the reduced 4KB flash on the F1764 requires recompiling with smaller code size or different optimization. The PPS (peripheral pin select) mappings must be re-validated when migrating across the family since some pins are PPS-capable on the F1768 but not on smaller variants. When migrating from the F1768 to F1769, note the additional 6KB flash and 512 bytes RAM, but confirm interrupt-vector layouts match - the F1769 may have additional peripheral interrupt sources.
