PIC16F1783-I/SS 概要
A microcontroller (MCU) is a single-chip computer containing a CPU core, program and data memory, and a rich set of on-chip peripherals. The PIC16F1783 sits within Microchip's PIC16F enhanced mid-range family, itself a subclass of the broader PIC microcontroller family, which is widely adopted in industrial, consumer, and automotive electronics. The -I/SS suffix indicates an industrial temperature range (-40C to +85C) in the SSOP-28 package.
Key features include a 12-bit ADC with up to 14 channels, an 8-bit DAC, two operational amplifiers, two high-speed comparators, a 16-bit PWM with PSMC (Programmable Switch Mode Controller), and Core Independent Peripherals (CIPs) such as CWG, NCO, and DSM. Communication interfaces cover I2C, SPI, and EUSART. These integrated analog blocks eliminate the need for many external components, reducing both BOM cost and PCB area in sensor-conditioning and closed-loop control designs.
Architecturally, the PIC16F1783 uses a 14-bit instruction word RISC engine with a hardware multiplier, an interrupt controller with context save, and a Peripheral Pin Select (PPS) module that remaps digital I/O functions, simplifying PCB routing. The XLP (eXtreme Low Power) design supports sleep currents below 50 nA typical, making it suitable for battery-powered and energy-harvesting applications.
Typical applications include industrial sensor signal conditioning, LED lighting and constant-current drivers, small appliance control, low-end BLDC/PMSM fan drivers via the PSMC, and portable instrumentation where the integrated op-amps condition transducer signals directly. Designers also deploy the part in white-goods user-interface controllers and IoT edge-node sensor hubs that require local analog processing.
When designing with the PIC16F1783-I/SS, plan analog and digital ground partitioning early, place the 0.1 uF VDD decoupling capacitor within 3 mm of the supply pin, and use Microchip's MPLAB X IDE with the XC8 compiler for code development. Programming and debugging are supported via the MPLAB PICkit 5 or ICD 4 in-circuit tools over the ICSP interface on pins 1 and 28.

主な用途
PIC16F1783-I/SS の用途: 6 件s: Industrial Sensor Signal Conditioning, LED Lighting and Constant-Current Drivers, Battery-Powered Portable Instrumentation, Small Appliance Control (White Goods), IoT Edge Sensor Node / Smart Home Hub, BLDC and PMSM Fan / Pump Motor Control.
Industrial Sensor Signal Conditioning
The PIC16F1783-I/SS fits industrial sensor signal conditioning because its integrated 12-bit ADC with 14 input channels, 2 op-amps, and 2 high-speed comparators eliminate most external analog circuitry. The two on-chip op-amps can be configured as instrumentation front-ends for bridge pressure sensors, RTD temperature sensors, or load-cell strain gauges, providing gain of up to 100x before the ADC samples. The 12-bit ADC delivers 0.8 mV resolution at a 3.3 V reference, sufficient for process-control accuracy. Unlike external ADC solutions, the integrated Core Independent Peripherals (CIPs) operate without CPU intervention, allowing continuous sensor monitoring while the CPU handles communication or higher-level tasks. Operating from 2.3 V to 5.5 V supports 4-20 mA loop and 24 V industrial bus interfaces when paired with external regulation.
おすすめ
LED Lighting and Constant-Current Drivers
The PIC16F1783-I/SS is ideal for LED lighting drivers thanks to its Programmable Switch Mode Controller (PSMC) and 16-bit PWM. The PSMC generates accurate timing and dead-band control for buck, boost, SEPIC, and flyback LED driver topologies, while the 16-bit PWM delivers dimming resolution down to 0.0015% at 32 MHz. The on-chip 12-bit ADC monitors LED current and voltage, closing the feedback loop with sub-1% regulation accuracy. The integrated op-amps can sense shunt current directly, eliminating external current-sense amplifiers. The XLP (eXtreme Low Power) design reduces standby current to <50 nA typical, meeting Energy Star standby requirements. Operating temperature range of -40 C to +85 C supports outdoor and architectural lighting enclosures.
おすすめ
Battery-Powered Portable Instrumentation
The PIC16F1783-I/SS excels in battery-powered portable instrumentation because of its XLP (eXtreme Low Power) design with typical sleep currents under 50 nA and active current under 4 mA at 32 MHz. The integrated 12-bit ADC and op-amps measure transducer signals directly, while Core Independent Peripherals perform signal acquisition without waking the CPU, extending battery life by orders of magnitude over polled architectures. Operating voltage down to 2.3 V allows direct connection to 2x AA alkaline or single Li-ion cells. The 256-byte EEPROM stores calibration constants non-volatilely, and the 7 KB flash supports on-board firmware updates via ICSP for in-the-field calibration cycles. The wide industrial temperature range (-40 C to +85 C) suits field-portable test and measurement equipment used in outdoor environments.
おすすめ
Small Appliance Control (White Goods)
The PIC16F1783-I/SS suits small appliance control in washing machines, dishwashers, microwave ovens, and induction cooktops due to its 7 KB flash, 12-bit ADC, and PSMC. The PSMC controls motor inverters for variable-speed pump and fan motors, while the 16-bit PWM drives triac-based heating elements with zero-crossing detection via the on-chip comparators. The 14-channel ADC reads multiple temperature sensors, water-level switches, and door interlocks through a single chip. With 256 bytes of EEPROM, user settings persist across power cycles. Operating voltage 2.3-5.5 V supports direct 3.3 V or 5 V logic, while the industrial temperature rating ensures reliability behind the appliance's user-facing enclosure.
おすすめ
IoT Edge Sensor Node / Smart Home Hub
The PIC16F1783-I/SS serves as the local analog-processing MCU in IoT edge sensor nodes and smart-home hubs. Its integrated 12-bit ADC, op-amps, and comparators condition sensor signals locally before communication, reducing the data rate and power consumption of the wireless link. Core Independent Peripherals (CIPs) handle sensor timing and threshold detection autonomously, waking the CPU only when meaningful events occur. The EUSART, I2C, and SPI interfaces connect to Wi-Fi/BLE modules, sensors, and EEPROM memory. XLP deep-sleep currents below 50 nA enable battery lifetimes exceeding 10 years on coin cells for slow-reporting edge nodes. Operating from 2.3-5.5 V supports both Li-ion and coin-cell battery sources.
おすすめ
BLDC and PMSM Fan / Pump Motor Control
The PIC16F1783-I/SS handles BLDC and PMSM motor control for low-power fans and pumps thanks to its PSMC and 16-bit PWM. The PSMC generates 6-step or sinusoidal commutation timing, while the high-speed comparators provide back-EMF zero-crossing detection without external sensors. The 12-bit ADC measures phase currents and bus voltage for closed-loop control. The on-chip op-amps can amplify shunt-resistor current-sense signals, reducing external component count. Operating from 2.3-5.5 V suits 5 V or 12 V motor systems with external gate drivers; the MCU logic operates from a regulated rail while directly interfacing with the driver IC. The wide operating temperature range supports industrial cooling fans and pumps.

設計ノート
Decouple both VDD pins (18 and 28) with a 0.1 uF ceramic capacitor placed within 3 mm of each pin, plus a bulk 1 uF to 10 uF tantalum or ceramic near the package. The PIC16F1783's XLP design keeps typical sleep current under 50 nA only when both analog and digital peripherals are properly disabled in firmware. Estimate: with 3.3 V supply and 32 MHz active mode, typical IDD is approximately 4 mA; verify with the manufacturer datasheet before relying on this for battery-life calculations.
The 28-pin SSOP (5.30 mm body, 0.65 mm pitch) requires careful land pattern design per the Microchip SSOP package drawing. Route the ICSP signals (ICSPCLK/ICSPDAT and PGC/PGD) to a 1x5 or 2x3 header for in-circuit programming access. Place the MCLR/VPP pull-up resistor (typically 10 kohm) close to pin 4, and route the capacitor on MCLR (typically 0.1 uF) directly to ground. Avoid long traces on the analog inputs (RA0-RA7) to minimize ADC sampling noise.
The SSOP-28 package has a thermal resistance (theta_JA) of approximately 80 C/W typical on a standard 2-layer JEDEC test board. At maximum operating ambient (85 C industrial) and typical 4 mA active current at 3.3 V, self-heating is well below 1 C. However, in closed-enclosure industrial designs with limited airflow, derate the maximum ambient by 5-10 C or use thermal vias to inner copper planes to maintain margin.
For accurate 12-bit ADC readings, place the 0.1 uF and 10 uF decoupling capacitors close to the VDD/VSS pins and avoid routing digital signals across the analog inputs. Use the Peripheral Pin Select (PPS) feature to assign the ADC inputs and op-amp outputs to dedicated analog-capable pins (PORTA), separating them from noisy digital I/O. The on-chip op-amps can be configured as unity-gain buffers to drive ADC inputs with low-impedance sources, improving ADC acquisition accuracy.
Do not leave the MCLR/VPP pin floating - tie it to VDD through a 10 kohm resistor with a 0.1 uF capacitor to VSS to prevent spurious resets from noise. Ensure the ICSP connector shares the ICSPDAT and ICSPCLK pins with the application circuit or include isolation resistors to prevent programming conflicts. The F1783's PSMC outputs must be properly configured with dead-band delays to avoid shoot-through in half-bridge motor driver applications.
