PIC16LF1782T-I/ML Übersicht
An 8-bit microcontroller is a single-chip computer that integrates a CPU core, program memory, data memory, peripherals, and I/O on one silicon die. In the broader system hierarchy, the MCU sits below application processors and above discrete logic; the PIC16F family uses a Harvard RISC architecture with a 14-bit instruction word, optimised for deterministic interrupt response and ultra-low power (XLP) operation - making this part especially suited to battery-powered and energy-harvesting designs.
Key on-chip peripherals include a 12-bit ADC, an 8-bit DAC, multiple PWM modules, comparators, and the Microchip eXtreme Low Power (XLP) sleep management, with active-mode current draw in the low-microamp range. The integrated 12-bit ADC provides up to 12 channels of high-resolution analogue conversion, allowing direct sensor interfacing without an external converter, while the 8-bit DAC supports programmable reference voltages or waveform generation.
Architecturally the PIC16LF1782 uses Microchip's enhanced mid-range 8-bit core with a 14-bit instruction word, hardware multiplier, and a C-compiler-friendly design. The LF (low-voltage/F-version) suffix indicates operation from 2.0 V to 3.6 V (suitable for 2.5 V and 3.3 V rails), and the 32 MHz internal oscillator eliminates an external crystal in many designs, reducing BOM cost and PCB area.
Typical applications include portable consumer electronics, IoT sensor nodes, low-power wireless nodes, LED lighting controllers, and battery management front-ends. The combination of on-board ADC, DAC, and PWM makes the device a single-chip solution for closed-loop analogue and mixed-signal control without requiring an external signal-chain IC.
When designing with this part, place decoupling capacitors (100 nF plus 1-10 uF bulk) close to the VDD/VSS pairs and use the exposed pad to provide both thermal relief and a low-inductance ground return. The 28-VQFN package requires careful PCB layout to ensure the exposed pad is soldered to a sufficiently large copper area for thermal dissipation.

Typische Anwendungen
PIC16LF1782T-I/ML ist geeignet für 6 Anwendungs: IoT Sensor Node Controller, Portable Consumer Electronics, LED Lighting Controller, Battery Management Front-End, Industrial Sensor Transmitter, Home Appliance User Interface.
IoT Sensor Node Controller
The PIC16LF1782T-I/ML fits IoT sensor nodes through three integrated features: a 12-bit ADC for direct sensor signal conditioning, an 8-bit DAC for programmable references or actuator drive, and XLP nanoWatt sleep modes that drop quiescent current to sub-microamp levels. With 256 B SRAM, 3.5 KB Flash, and a 32 MHz enhanced mid-range core, it handles local decision-making, simple protocol stacks (Modbus RTU slave, I2C/SPI bridging), and event-driven duty cycling. The 2.0-3.6 V LF supply range supports direct connection to a single Li-ion, two AA cells, or a 3.3 V regulated rail without an extra LDO.
Empfohlen
Portable Consumer Electronics
The PIC16LF1782T-I/ML fits portable consumer electronics because its 32 MHz enhanced mid-range core delivers responsive user-interface handling and PWM generation for motor/LED control, while the 2.0-3.6 V LF range pairs directly with Li-ion or Li-Po cells. The 12-bit ADC reads battery voltage, button matrices, and capacitive-touch front-ends; the 8-bit DAC drives audio click or haptic waveforms. XLP sleep modes extend battery life between user interactions. At 6 x 6 mm in VQFN (ML), the part occupies minimal board area, freeing PCB real estate for the wireless SoC and power-management IC.
Empfohlen
LED Lighting Controller
The PIC16LF1782T-I/ML fits LED lighting controllers because its multiple PWM modules, 12-bit ADC for ambient-light sensing and colour-mixing closed loops, and 8-bit DAC for reference-current setting provide a single-chip solution. The 32 MHz core generates smooth PWM dimming at frequencies above the audible band (>20 kHz), eliminating coil whine. The 2.0-3.6 V LF supply runs directly from 3.3 V regulated LED-driver rails, while 256 B SRAM stores fade patterns and 3.5 KB Flash holds dimming curves. XLP sleep drops the standby current below 1 uA when lighting is off.
Empfohlen
Battery Management Front-End
The PIC16LF1782T-I/ML fits battery management front-ends because its 12-bit ADC monitors cell voltage and current shunt with high resolution, while its 8-bit DAC drives the reference for a separate coulomb-counter or charger IC. XLP sleep current (sub-uA) preserves battery charge when the system is idle. The 2.0-3.6 V supply is ideal for single-cell Li-ion/2x AA chemistries, and the industrial -40C to +85C range covers outdoor BMS deployments. The 28-pin VQFN (ML) 6x6 mm package fits compact BMS boards for power tools, e-bikes, and small UPS modules.
Empfohlen
Industrial Sensor Transmitter
The PIC16LF1782T-I/ML fits 4-20 mA industrial sensor transmitters because its 12-bit ADC digitises bridge/thermocouple inputs with sufficient resolution for process-control loops, while the 8-bit DAC calibrates the loop current to <0.1% FS. The 32 MHz core executes linearisation and PID control with sub-millisecond loop times. The industrial -40C to +85C temperature range handles outdoor cabinet and field-mount installations, and XLP nanoWatt sleep supports loop-powered (2-wire) 4-20 mA transmitters running from <4 mA quiescent current. The 28-pin VQFN (ML) allows compact head-mount form factors.
Empfohlen
Home Appliance User Interface
The PIC16LF1782T-I/ML fits home appliance user-interface modules because its 32 MHz core drives segmented LCDs, button matrices, and rotary encoders with deterministic interrupt response, while the 12-bit ADC reads knob positions and touch-pad capacitance directly. XLP sleep drops standby to <1 uA, meeting energy-star idle targets for white goods. The 2.0-3.6 V LF range is compatible with 3.3 V appliance rails, and the 3.5 KB Flash stores multi-language UI strings. The 28-pin VQFN (ML) 6x6 mm package allows drop-in replacement of legacy 8-bit MCUs in compact appliance-control boards.

Wichtigste Unterscheidungsmerkmale
- Integrated 12-bit ADC plus 8-bit DAC in a single MCU (vs. PIC16LF1769-I/ML)
- XLP nanoWatt sleep capability for sub-uA standby (vs. PIC16F1782T-I/ML)
- Memory upgrade path within the same footprint (vs. PIC16F1783T-I/ML)
Designhinweise
Estimated: The 28-pin VQFN (ML) 6x6 mm package has an exposed thermal pad (EP) that must be soldered to a PCB copper pour for thermal relief and a low-inductance ground return. A minimum 4 x 4 mm copper pour on a 1 oz copper 4-layer board yields approximately theta_JA = 30 C/W. For PIC16LF1782T-I/ML running at 32 MHz with XLP active, typical power dissipation is below 20 mW, so the part does not require a dedicated heatsink - only the EP solder joint and PCB copper pour. Skip the EP connection only after validating thermal performance in worst-case conditions.
Place a 100 nF (0.1 uF) ceramic decoupling capacitor as close as possible to each VDD/VSS pair, plus a 1 uF to 10 uF bulk capacitor at the supply pin. For designs using the internal 32 MHz oscillator, route the VSS trace as a star ground directly to the EP copper pour to minimise switching noise on the analogue ADC inputs. Keep the ICSP pins (RB6/PGC and RB7/PGD) accessible for in-circuit programming and debugging, and reserve a 6-pin ICSP header footprint for production programming.
Do not exceed 3.6 V on the LF variant (PIC16LF1782T-I/ML). For 5 V supplies, choose the non-LF PIC16F1782T-I/ML or PIC16F1783T-I/ML. The VDDCORE pin (pin 27 on the VQFN) requires a decoupling capacitor (typically 100 nF) tied to VSS - omitting it can cause core instability under high MIPS loads. The exposed pad (EP) must be soldered to VSS for both electrical and thermal reasons; an unsoldered EP can cause erratic ADC readings and code-execution failures.
Estimated: When using the 12-bit ADC at full 32 MHz core clock, switch to a slower ADC clock or use the ADC dedicated RC oscillator to avoid -3 dB of effective resolution from digital switching noise coupling into the analogue inputs. Add a 100 nF bypass capacitor on each AVSS/AVDD pair if separate analogue pins are bonded out, and route ADC traces perpendicular to high-current switching traces. For low-current sensor measurements (sub-uA sources), buffer the source with an op-amp to prevent ADC input leakage from biasing the reading.
Compliance-Informationen
RoHS compliant per Microchip product page and multiple distributor listings (Veswin, ET/EETI, Vyrian). REACH SVHC declaration and halogen-free status are available on request from Microchip. Not AEC-Q100 qualified - choose a 'F'-suffix AEC-Q100 part (not in this family) for automotive applications.
