PIC16F1782-I/SO Обзор
Key features include a built-in 12-bit ADC, an 8-bit DAC, two op-amps, three 5-bit DACs, three timers, enhanced PWM, mTouch capacitive sensing, and the eXtreme Low Power (XLP) sleep modes that draw microampere-level quiescent current. Supply voltage spans 2.3 V to 5.5 V, with operating current typically below 2 mA at full speed.
Typical applications include low-power sensor signal conditioning with on-chip op-amps, LED lighting with hardware PWM, consumer white goods with capacitive touch keypads, battery-powered IoT endpoints, and mixed-signal front-end boards that benefit from the integrated ADC plus DAC.
Design considerations focus on decoupling, oscillator selection between internal 32 MHz HFINTOSC and external crystal, and in-circuit serial programming (ICSP) via PGC/PGD. Code development uses the MPLAB X IDE with the XC8 compiler and PICkit 5 programmer.

Типичное применение
PIC16F1782-I/SO подходит для 6 применениеs: Low-Power Sensor Signal Conditioning, Battery-Powered IoT Edge Nodes, Capacitive Touch User Interface, LED Lighting and PWM Control, Consumer White Goods and Appliances, Mixed-Signal Front-End Boards.
Low-Power Sensor Signal Conditioning
The PIC16F1782-I/SO's two integrated op-amps, 12-bit ADC, and 8-bit DAC let a single IC amplify and digitize a thermistor or strain-gauge bridge while also generating a 4-20 mA-loop DAC bias. At 32 MHz CPU with HFINTOSC, deterministic 125 ns instruction cycles support 1 kHz control loops. XLP sleep below 1 uA means a 3 V coin cell can run a periodic logger for multiple years.
Рекомендуется
Battery-Powered IoT Edge Nodes
XLP modes drop quiescent current into the sub-microampere range while retaining RAM and Watchdog Timer wake-ups. With 3.5 KB Flash and 256 B SRAM, this MCU runs a sensor read, threshold check, and interrupt-driven radio TX without external components. Internal HFINTOSC accuracy of ±1% removes the need for an external 32.768 kHz crystal, shrinking the BOM.
Рекомендуется
Capacitive Touch User Interface
The on-chip mTouch peripheral turns RA0-RA5 and RC0-RC4 into capacitive sense channels for up to nine touch buttons or a slider. Combined with the 12-bit ADC for force/proximity sensing and PWM for haptic feedback, the PIC16F1782-I/SO delivers a complete UI controller at low cost. Internal op-amps drive the touch guard ring for noise immunity.
Рекомендуется
LED Lighting and PWM Control
Enhanced PWM with up to four channels and 10-bit resolution drives constant-current LED strings directly via MOSFETs. The 32 MHz production rate keeps PWM jitter below 0.5%, eliminating visible flicker at 1 kHz dimming. Internal 5-bit DACs provide trim offsets for multi-channel RGB white-balance tuning without external reference ICs.
Рекомендуется
Consumer White Goods and Appliances
From coffee machines to induction cooktops, the PIC16F1782-I/SO integrates op-amps, comparators, ADC, and PWM that handle temperature sensing, current feedback, and TRIAC drive. Industrial -40C to +85C rating covers kitchen environments. mTouch replaces mechanical buttons for sealed, easy-to-clean front panels.
Рекомендуется
Mixed-Signal Front-End Boards
For data-acquisition front-ends that need a local MCU for housekeeping, the PIC16F1782-I/SO's 12-bit ADC at 100 ksps captures analog signals while the 8-bit DAC and 5-bit DACs provide excitation and bias. The 32 MHz MIPS handles digital filtering, linearization, and UART/SPI/I2C forwarding to a host processor with negligible latency.

Заметки по проектированию
Place a 100 nF ceramic decoupling capacitor as close as possible to the VDD pin (pin 26) and VDDIO (pin 27), with a bulk 10 uF tantalum or aluminum-polymer cap on the supply rail. For battery applications, use a separate 1 uF reservoir near VCAP (pin 1) to stabilize the internal LDO and minimize voltage drop during HFINTOSC bursts.
Route the ICSP signals PGC (RB6) and PGD (RB7) directly to a 6-pin header or tag-connect pads. Keep traces shorter than 50 mm and avoid running them parallel to high-current motor or PWM lines to prevent programming glitches. Provide a ground ring around the mTouch electrodes for noise immunity.
Do not forget to configure the unused analog channels as digital I/O via the ANSEL registers, or floating inputs can cause excess current draw. Always set the ADC conversion clock to a valid value (Fosc/2 to Fosc/64) and wait the acquisition time before triggering conversion. Verify oscillator configuration bits match the chosen clock source before locking the code.
