PIC16LF1782T-I/MV 概述
Key features include a 12-bit differential ADC with up to 11 channels, an 8-bit DAC, two operational amplifiers, two 10-bit PWM modules, and support for EUSART, I2C, and SPI communication peripherals. The PIC16LF1782T-I/MV integrates capacitive touch sensing (mTouch) and a hardware multiplier, enabling single-cycle 8x8 multiplication. The 28-pin UQFN (4x4 mm) package provides a compact surface-mount footprint suited for space-constrained PCB layouts.
The PIC16LF1782 uses the enhanced mid-range 16-bit instruction set (49 instructions, 16-bit opcodes) with a 14-bit program word width and a 16-level hardware stack. The CPU executes one instruction per clock cycle at 32MHz, delivering 8 MIPS throughput. Integrated peripherals such as the 12-bit ADC with acquisition timer reduce BOM count in sensor-interface designs. The nanoWatt XLP technology delivers typical sleep currents below 100 nA with retention RAM and Watchdog Timer operation.
Typical applications include industrial sensor conditioning, portable medical instrumentation, battery-powered IoT nodes, low-power motor control loops, LED lighting controllers, and capacitive touch user interfaces. The combination of high-resolution ADC, on-chip op-amps, and DAC enables closed-loop analog signal chain implementations without external active components.
When designing with this device, ensure the UQFN exposed pad is soldered to a sufficient copper pour for thermal dissipation. Use MPLAB X IDE with the XC8 compiler and verify the supply voltage and frequency combination against the device's voltage-frequency derating curve. The 'T' suffix in the part number designates Tape & Reel packaging per Microchip ordering conventions.

典型应用
PIC16LF1782T-I/MV 适用于 6 应用s: Industrial Sensor Signal Conditioning, Portable Battery-Powered Medical Instruments, Battery-Powered IoT Sensor Nodes, Capacitive Touch User Interfaces, LED Lighting Controllers, Low-Power Closed-Loop Motor Control.
Industrial Sensor Signal Conditioning
The PIC16LF1782T-I/MV is well suited to industrial sensor conditioning because it integrates a 12-bit differential ADC, two on-chip operational amplifiers, and an 8-bit DAC on a single 32MHz die. The on-chip op-amps can buffer and amplify thermocouple, bridge, or strain-gauge signals directly without external active components, while the 12-bit ADC delivers 4096-step resolution for accurate measurement. Operating from 1.8V to 5.5V, the LF variant draws nanoWatt XLP sleep currents below 100 nA, making it ideal for 4-20 mA loop-powered sensor transmitters. Place 100nF decoupling on VDD close to the UQFN exposed pad.
推荐
Portable Battery-Powered Medical Instruments
The PIC16LF1782T-I/MV fits portable medical devices because its LF process delivers sub-100 nA sleep currents with retention RAM preserved, enabling multi-month coin-cell operation in patient-worn health monitors. The 12-bit ADC captures photoplethysmography (PPG), pulse-oximetry, or temperature sensor signals with adequate resolution for clinical-grade wearables. Its 1.8V minimum supply supports direct LiMnO2 or alkaline battery stacks. The integrated mTouch peripheral enables capacitive touch user interfaces without extra components, reducing BOM and PCB area in miniaturized medical disposables.
推荐
Battery-Powered IoT Sensor Nodes
The PIC16LF1782T-I/MV is a strong match for IoT end nodes because it combines the nanoWatt XLP deep-sleep mode with a 12-bit ADC, EUSART, I2C, and SPI peripherals in a 4x4 mm UQFN package. Sleep currents below 100 nA allow multi-year battery life when the MCU wakes periodically to read sensors and transmit data. The 32MHz CPU provides ample throughput to run a small LoRa/Sigfox protocol stack or BLE HCI command set. The compact UQFN-28 (MV) footprint enables miniaturized sensor pucks for smart home, agriculture, and asset tracking deployments.
推荐
Capacitive Touch User Interfaces
The PIC16LF1782T-I/MV supports capacitive touch UI designs via the integrated mTouch peripheral and CTMU (Charge Time Measurement Unit) which can detect proximity events. The 12-bit ADC and on-chip op-amps enable advanced touch decoding algorithms in firmware, eliminating the need for an external touch controller. Designers can implement buttons, sliders, and wheel controls on PCB pads using only the MCU. With 256 bytes RAM and 3.5KB Flash, the device can run a touch UI library alongside application logic in compact consumer and appliance designs.
推荐
LED Lighting Controllers
The PIC16LF1782T-I/MV is suited to LED lighting controllers because it integrates two 10-bit PWM channels and a hardware multiplier for closed-loop dimming control. The 8-bit DAC and on-chip op-amps enable constant-current drive feedback loops, supporting analog dimming plus PWM dimming in the same firmware. Its 1.8V-5.5V operation allows direct connection to single-cell Li-ion or 3.3V regulator rails. The PIC16LF1782's nanoWatt XLP modes reduce standby power below typical LED driver controller baselines, helping designs meet energy-star idle budgets.
推荐
Low-Power Closed-Loop Motor Control
The PIC16LF1782T-I/MV delivers small closed-loop DC motor and stepper control because its 32MHz core, 12-bit ADC, and on-chip op-amps support back-EMF sensing, current sensing, and PID loops in firmware. Two 10-bit PWM channels can drive an H-bridge or half-bridge stage directly. The 1.8V minimum supply suits single-cell Li-ion battery motors such as cordless screwdrivers, fans, and small pumps. The LF-process XLP modes reduce standby current to nanoAmp levels between command updates, extending battery runtime in portable appliances.

设计说明
The PIC16LF1782T-I/MV is supplied in a 28-pin UQFN (MV) package with an exposed thermal pad on the underside. The exposed pad is the primary heat-dissipation path and MUST be soldered to a copper pour on the top layer of the PCB. For continuous 32MHz operation, use at least 1 square inch of copper connected to the pad. If the pad is left floating, junction temperature can rise above the -40C to +85C industrial limit during sustained full-load operation.
Place a 100nF decoupling capacitor as close as possible to each VDD pin (pins 10 and 20) with the return path directly to the adjacent VSS pin. Add a bulk 10uF ceramic or tantalum capacitor near the IC for transient load support. The LF-process variant operates from 1.8V to 5.5V but the maximum CPU frequency of 32MHz is only achievable above 2.0V - consult the voltage-frequency derating curve in datasheet DS40001742D before designing at sub-2V rails.
UQFN-28 has 0.4mm pitch leads which require careful PCB layout. Use NSMD (Non-Solder Mask Defined) pads with a stencil aperture of approximately 0.25-0.30 mm to prevent solder bridges. Route signal traces out from the pads on 0.2mm (8 mil) width with 0.2mm spacing. Maintain a continuous ground plane under the device to provide thermal sinking and EMI shielding. Avoid placing tall components within 2 mm of the UQFN to keep the reflow profile uniform during assembly.
Do not confuse the 'T' suffix with a temperature grade - 'T' designates Tape & Reel packaging per Microchip ordering convention. The PIC16LF1782T-I/MV is industrial-grade (-40C to +85C); for extended temperature (-40C to +125C) choose the PIC16LF1782-E/MV variant. Also note that the LF variant's 1.8V-5.5V operation is NOT a guarantee of performance down to 1.8V at full 32MHz speed; the datasheet specifies a lower frequency at low voltages to ensure timing accuracy.
