PIC16F1782T-I/SO - 8-bit MCU, 32MHz, 3.5KB Flash | Microchip
MPN: PIC16F1782T-I/SO ✓ Hoạt độngPIC16F1782T-I/SO Tóm tắt
An 8-bit PIC microcontroller is a RISC-architecture CMOS flash MCU that executes instructions in a single clock cycle (200 ns at 32 MHz). Within the broader hierarchy, it sits at: PIC microcontroller -> 8-bit MCU -> microcontroller (MCU) -> embedded IC -> semiconductor. Its 49-instruction instruction set is upward-compatible with the PIC10/12/16 baseline families, making code migration simple across the entire PIC16 portfolio.
Key features include 12-channel 12-bit ADC with internal voltage reference, an integrated 8-bit DAC (5-/8-bit selectable on reference devices), 6 PWM modules with complementary outputs, a 32 MHz internal oscillator with +/-2% accuracy, and rich communication peripherals (I2C, SPI, AUSART). The wide 2.3V to 5.5V operating range and nanoWatt XLP sleep currents below 50 nA (typical) make it ideal for battery-powered industrial and consumer products that must survive years on a single coin cell.
The device uses a 14-bit instruction word with a hardware multiplier for shift-based peripherals and an enhanced mid-range core that adds C-optimized addressing modes, hardware stack overflow/underflow reset, and a memory access partition. Programming and debug are handled through Microchip's MPLAB X IDE and ICD/PICKit toolchain, with the PICkit 5 providing fast production-grade in-circuit programming.
Typical applications include battery-powered sensor nodes, LED lighting drivers, motor-control signal processors, automotive interior accessories, and small home-appliance user interfaces. The 12-bit ADC and 8-bit DAC combination is particularly valued in closed-loop control loops where digital sensing drives analog actuation.
When designing with this part, place a 0.1 uF decoupling capacitor within 5 mm of the VDD pin and use bulk capacitance of at least 10 uF to stabilize the internal regulator. Ensure MCLR has a valid logic-high tie (>=VDD-0.2 V) at all times for proper device operation; floating MCLR can trigger unintended reset events.

Ứng dụng tiêu biểu
PIC16F1782T-I/SO phù hợp cho 7 Áp dụngs: Battery-Powered Sensor Node, LED Lighting Dimmer Controller, Small Motor Control (Brushed DC / Fan Speed), Automotive Interior Accessory, Home Appliance User Interface, Industrial Process Sensor / 4-20 mA Loop, IoT Edge Node with Sleep Duty Cycling.
Battery-Powered Sensor Node
The PIC16F1782T-I/SO fits battery-powered sensor nodes thanks to its nanoWatt XLP sleep currents below 50 nA typical, 2.3V to 5.5V operating range, and integrated 12-bit ADC for direct sensor digitization. At 1 Hz sample rate the part consumes so little power that a CR2032 coin cell can power a temperature/humidity node for 5-plus years. The 32 MHz core processes FFT-style sensor fusion on demand, then immediately returns to deep sleep under interrupt control.
Được đề xuất
LED Lighting Dimmer Controller
The PIC16F1782T-I/SO is well suited for LED lighting dimmer and color-mixing controllers due to its 6 PWM modules with complementary outputs, 12-bit ADC for ambient-light feedback, and 8-bit DAC for analog set-point generation. Multiple PWM channels can drive RGB or warm-white/cool-white LED strings independently. Operating from a single 3.3V or 5V rail with very low quiescent current, it eliminates external FET drivers in small-form-factor luminaires.
Được đề xuất
Small Motor Control (Brushed DC / Fan Speed)
The PIC16F1782T-I/SO's 6 PWM channels and 32 MHz throughput make it appropriate for small brushed-DC motor speed loops and fan-speed controllers. The 12-bit ADC reads back-tach or shunt current while the PWM drives the FET gate directly at up to 32 kHz. The 8-bit DAC provides a programmable reference for comparator-based current-trip protection without external components.
Được đề xuất
Automotive Interior Accessory
The PIC16F1782T-I/SO is widely used in automotive interior accessories such as ambient lighting controllers, vanity mirror drivers, and HVAC mode selectors. Its industrial -40C to +85C operating range, robust PIC16 enhanced mid-range core, and integrated 12-bit ADC make it AEC-Q100-friendly when properly designed. The device operates directly from a 5V regulated supply after a TVS-protected LIN/CAN bus interface.
Được đề xuất
Home Appliance User Interface
In washing machines, coffee makers, and countertop kitchen appliances, the PIC16F1782T-I/SO handles key-scan input, 7-segment or basic LCD display drive, and PWM-based load control. The 256 B EEPROM stores user preferences and last-mode state across power cycles without external memory. The 2.3V to 5.5V range allows direct connection to a rectified 5V mains-derived supply after regulation.
Được đề xuất
Industrial Process Sensor / 4-20 mA Loop
The PIC16F1782T-I/SO fits industrial process sensor transmitters because of its 12-bit ADC with internal voltage reference, AUSART for HART-modem-friendly UART communication, and wide 2.3V to 5.5V operating range. The 8-bit DAC can synthesize the 4-20 mA loop output when paired with a current-loop driver. Industrial -40C to +85C rating is appropriate for unheated cabinet mounting.
Được đề xuất
IoT Edge Node with Sleep Duty Cycling
For battery-backed IoT edge nodes that wake periodically to measure, transmit, and return to sleep, the PIC16F1782T-I/SO's XLP nanoWatt mode and 32 MHz wake-and-execute capability are ideal. The AUSART peripheral connects directly to a sub-GHz or BLE module; the 12-bit ADC reads sensor input during the active phase. Average current of well under 5 uA is achievable for many sensor sampling scenarios.

Ghi chú thiết kế
Place a 0.1 uF decoupling capacitor within 5 mm of the VDD pin and a 10 uF bulk capacitor near the MCU on every 28-SOIC PIC16F1782T-I layout. The on-chip voltage regulator is sensitive to supply droop during ADC conversion bursts. For nanoWatt XLP designs, switch peripherals off before entering sleep to achieve the sub-50 nA sleep-current figures cited in the datasheet.
MCLR must be tied to VDD through a 10 kohm pull-up resistor, never left floating. A floating MCLR causes spurious resets and unreliable programming-mode entry. For in-circuit serial programming (ICSP) with PICKit, the MCLR/VPP line must be able to reach 8V; place a small Schottky diode and series resistor as recommended in Microchip debug header documentation to protect against programmer back-drive into the rest of the circuit.
For I2C bus, place 4.7 kohm pull-ups on SCL and SDA within 50 mm of the MCU and verify against the 400 kHz Fast-Mode timing budget. For SPI at higher speeds, route the SCK/MOSI/MISO traces as a matched-length group with a continuous ground reference beneath. If the ADC is used at full 12-bit resolution, add a 10 nF bypass on AVSS/AVDD and consider using the FVR module as the ADC reference to avoid supply-noise coupling.
