MPN: PIC16F1782-I/SS ✓ AktifPIC16F1782-I/SS Ringkasan
A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, working RAM, and a rich set of peripherals such as analog-to-digital converters, digital-to-analog converters, timers, and communication interfaces. PIC microcontrollers from Microchip occupy the 8-bit MCU tier in the embedded semiconductor hierarchy, sitting below 32-bit ARM Cortex-M parts but above simple digital logic, and are widely used in cost- and power-sensitive applications. The PIC16F1782 specifically belongs to the enhanced mid-range family, gaining CIP (Core Independent Peripherals) such as the 12-bit ADC, 8-bit DAC, operational amplifier, fast comparator, and Programmable Switch Mode Controller (PSMC) that historically required external components.
Key features of the PIC16F1782-I/SS include 12-bit resolution ADC with up to 11 channels, an 8-bit DAC, two op-amps, a high-speed comparator with 50 ns response, CCP, EUSART, I2C/SPI, and 25 mA source/sink per I/O with 100 mA total. The device supports internal oscillator accuracy to within +/-1% via the HFINTOSC, eliminating an external crystal in many designs. NanoWatt XLP technology provides sleep currents below 50 nA typical, making the part attractive for battery-powered sensor nodes and energy-harvesting applications. The 28-SSOP package exposes 24 GPIO lines, sufficient for most small-form-factor embedded products.
Typical applications for the PIC16F1782 include LED lighting controllers with constant-current regulation through the PSMC, sensor signal conditioning using the on-chip op-amp, small DC motor control via the PSMC and CCP, smoke detectors and CO sensors, battery chargers, consumer appliances with graphical or segmented LCDs, and compact sensor hubs in industrial IoT nodes. The combination of analog integration and eXtreme Low Power (XLP) makes the part a frequent choice for low-power mixed-signal designs that previously required separate op-amps, comparators, and power controllers.
When designing with this part, pay attention to the VDD range (2.5-5.5 V for F-grade, 1.8-3.6 V for LF-grade) and use the PPS (Peripheral Pin Select) feature to remap digital peripherals to free I/O pins. The PSMC must be configured for the target topology (buck, boost, flyback) using Microchip's code configurator. Decoupling should follow the datasheet typical-application section, with a 100 nF VDD pin cap and a bulk capacitor on the analog rail.

Aplikasi Umum
PIC16F1782-I/SS cocok untuk 6 aplikasis: LED Lighting Controller, Sensor Signal Conditioning, Smoke Detector and CO Sensor, Small DC Motor Control, Battery Charger, Industrial Sensor Hub.
LED Lighting Controller
The PIC16F1782-I/SS fits LED lighting controllers because its Programmable Switch Mode Controller (PSMC) drives constant-current buck/boost topologies directly, while two on-chip op-amps close the current-sense loop. Designers run the PSMC at up to 250 kHz to drive a MOSFET and current-sense resistor, eliminating a dedicated LED driver IC. The 12-bit ADC monitors LED temperature via an NTC, and XLP sleep drops below 50 nA between brightness changes. This reduces BOM cost versus discrete driver plus MCU solutions.

Sensor Signal Conditioning
The PIC16F1782-I/SS is well-suited to sensor signal conditioning because its two on-chip op-amps and 12-bit ADC with 11 channels remove external amplifiers and a separate ADC. One op-amp amplifies a bridge sensor (load cell, pressure), the second provides active low-pass filtering, and the 12-bit ADC digitizes the result at up to 100 ksps. The 8-bit DAC drives an excitation bias, and the fast comparator triggers interrupt on threshold crossings. XLP sleep below 50 nA allows battery-powered IoT sensor nodes to run for years on a coin cell.
Direkomendasikan
Smoke Detector and CO Sensor
The PIC16F1782-I/SS powers smoke and CO detectors because its high-speed comparator (50 ns response) captures photoelectric chamber pulses with low jitter, while the 12-bit ADC digitizes electrochemical CO cell output for parts-per-million calculation. XLP sleep currents under 50 nA let the detector run for ten years on a single lithium battery. The internal 32 MHz oscillator avoids an external crystal, reducing BOM and improving long-term reliability in ceiling-mounted installations.
Direkomendasikan
Small DC Motor Control
The PIC16F1782-I/SS handles small DC and BLDC motor control because its PSMC generates complementary PWM with programmable dead-time, replacing a dedicated motor-driver pre-driver. The 12-bit ADC samples current-sense and back-EMF signals; CCP modules provide quadrature encoder input or timer capture for RPM measurement. The on-chip op-amp conditions shunt-resistor current sense, and EUSART links to a host controller or HMI for variable-speed tools and appliances.
Direkomendasikan
Battery Charger
The PIC16F1782-I/SS builds linear and switched-mode battery chargers because the PSMC, op-amp, and 12-bit ADC combine to implement CC/CV profiles without external control ICs. The DAC programs constant-current reference; the comparator terminates charge on delta-peak detection; and EEPROM stores chemistry profiles for Li-ion, NiMH, and lead-acid. XLP deep sleep below 50 nA suits maintenance/trickle chargers that draw near-zero standby power.
Direkomendasikan
Industrial Sensor Hub
The PIC16F1782-I/SS is a good fit for industrial sensor hubs because it aggregates multiple analog inputs (12-bit ADC, 11 channels), digital interfaces (I2C, SPI, EUSART), and on-chip op-amps for signal conditioning in a single 28-SSOP. RS-485 via EUSART plus an external transceiver connects to factory networks. The wide 2.5-5.5 V supply tolerance accepts 5 V industrial rails directly. NanoWatt XLP suits energy-harvesting installations where the hub must run from a small solar cell.

Diferensiator Kunci
- On-chip PSMC eliminates external switch-mode controller (vsPIC16F1713-I/SS)
- 2 on-chip op-amps vs 1 on PIC16F1713 (vsPIC16F1713-I/SS)
- XLP sleep below 50 nA vs LF variant family (vsPIC16LF1782-I/SS)
Catatan Desain
Estimated: at 32 MHz active current is typically ~5 mA at 5V, dropping to ~1.2 mA at 3.3V. Place a 100 nF decoupling capacitor within 5 mm of each VDD/AVDD pin and a bulk 10 uF tantalum at the regulator output. For battery designs, use the LF variant (1.8-3.6V) to extend runtime and switch to the LFINTOSC (31 kHz WDT source) in sleep for sub-50 nA quiescent current per the Microchip PIC16F178x datasheet.
Route ICSPDAT and ICSPCLK (RB6/RB7) directly to a programming header with no series resistors or buffers - Microchip programmers require direct access. Keep the MCLR pin trace short and add a 10 kohm pull-up to VDD with a 100 nF cap to ground for in-circuit debug stability. The 28-SSOP land pattern follows JEDEC MS-012 with 0.65 mm pitch; pad length should be 1.0 mm minimum for hand-soldering rework.
Do not apply voltage to any pin before VDD is stable, especially on PORTA analog pins - this can latch-up the device through the ESD diodes. Configure unused I/O as outputs low to minimize shoot-through current in sleep. When migrating from PIC16F877 or PIC16F887 code, note that the PIC16F1782 uses PPS for peripheral remapping - older fixed-pin assignments require remap to work.
