PIC16LF1783-I/SP 概要
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory (flash), data memory (RAM), non-volatile storage (EEPROM), and peripherals onto one die. Within the broader microcontroller taxonomy, the PIC16LF1783 belongs to the PIC16 enhanced mid-range family, which sits under Microchip's PIC® XLP™ (eXtreme Low Power) product line. XLP technology targets battery-powered and energy-harvesting applications by minimizing active and sleep currents, allowing the MCU to operate directly from a 1.8 V supply rail.
The PIC16LF1783-I/SP runs at speeds up to 32 MHz, executing most instructions in a single 125 ns cycle, and integrates high-performance analog peripherals uncommon in this class - notably a 12-bit ADC (analog-to-digital converter) with up to 14 channels and an 8-bit DAC (digital-to-analog converter). It also includes a 10-bit DAC, operational amplifiers, comparators, PWM modules, and the standard enhanced mid-range core peripherals. The 'LF' prefix denotes the low-voltage (1.8 V to 3.6 V) variant, while the 'I' suffix designates the industrial temperature range of -40 °C to +85 °C. The 'SP' package code marks the 28-pin SPDIP.
Typical applications include portable instrumentation, sensor signal conditioning, LED lighting controllers, low-power IoT nodes, and consumer devices. The integrated 12-bit ADC and on-chip op-amps reduce bill-of-materials cost for transducer front-ends, while the XLP active/sleep current profile supports years of battery life on coin cells.
When designing with this part, allocate careful PCB routing for the analog signals (AVDD/AVSS separation) and use decoupling capacitors within 5 mm of each supply pin. Verify in-circuit serial programming (ICSP) connections follow Microchip's recommended layout, since the through-hole SPDIP package is often chosen for prototype and educational development boards where repeated reprogramming is expected.

主な用途
PIC16LF1783-I/SP の用途: 7 件s: Battery-Powered IoT Sensor Nodes, Portable Medical Devices, Industrial Process Control, LED Lighting Controllers, Consumer Remote Controls, Automotive Body Electronics (Non-Safety), Educational Development Boards.
Battery-Powered IoT Sensor Nodes
The PIC16LF1783-I/SP's XLP architecture with nanoamp sleep current and 1.8 V minimum supply makes it ideal for coin-cell-powered wireless sensor nodes. Its integrated 12-bit ADC (up to 14 channels) and on-chip op-amps allow direct connection to thermocouples, load cells, and bridge sensors without external analog ICs. Active current at 1 MHz is typically under 100 µA/MHz at 1.8 V, enabling multi-year battery life. The 7 KB flash holds small sensor-fusion firmware with calibration tables. Use the SPI/I2C modules for an external radio transceiver, and the ICSP/ICD pins for field firmware updates.
おすすめ
Portable Medical Devices
The PIC16LF1783-I/SP fits handheld medical devices such as glucose meters, pulse oximeters, and patient thermometers. Its 12-bit ADC provides the resolution needed for accurate photodiode or thermistor readings, while the integrated op-amps implement transimpedance amplifiers without external components. Operating from 1.8 V to 3.6 V supports direct Li-ion or 2xAA operation. The industrial -40 °C to +85 °C temperature range handles sterilisation environments. XLP sleep current keeps standby power negligible between measurements, extending battery life across thousands of readings.
おすすめ
Industrial Process Control
Factory-floor controllers, 4-20 mA loop transmitters, and HMI keypads benefit from the PIC16LF1783-I/SP's industrial -40 °C to +85 °C rating and high-integration analog peripherals. The 12-bit ADC digitizes multiple process variables, while the PWM module drives valve actuators or LED indicators. The on-chip comparators handle windowed fault detection (over-temperature, over-current) without an external supervisor. The 256-byte EEPROM stores non-volatile calibration constants and serial numbers for traceability. Use the EUSART for RS-485 communication via an external transceiver like the MAX485.
おすすめ
LED Lighting Controllers
The PIC16LF1783-I/SP drives architectural and decorative LED fixtures with smooth dimming and color mixing. Its multiple PWM channels (Capture/Compare/PWM) and 8-bit DAC produce high-resolution analog dimming signals, while the 12-bit ADC reads ambient light sensors for closed-loop brightness control. Operating from 1.8 V to 3.6 V simplifies constant-current driver integration. The XLP low-power modes keep standby draw minimal when the fixture is off, supporting Energy Star and EU EcoDesign standby limits. The flash-resident firmware handles DMX or DALI protocols via UART or external interfaces.
おすすめ
Consumer Remote Controls
Universal remote controls and BLE/IR bridges leverage the PIC16LF1783-I/SP's low active current and deep sleep modes for months of battery life on a pair of AAA cells. The integrated op-amps and comparators condition IR-receiver photodiode signals, while PWM generates accurate 38 kHz carrier waveforms for IR transmission. The 7 KB flash comfortably fits a small database of device IR codes and learning algorithms. ICSP support allows post-assembly firmware customization for OEM variants. Use the EUSART to communicate with an external BLE module for smart-home integration.
おすすめ
Automotive Body Electronics (Non-Safety)
For non-safety automotive body modules such as interior lighting controllers, seat heaters, and accessory timers, the PIC16LF1783-I/SP provides sufficient analog integration and -40 °C to +85 °C industrial temperature range. The 12-bit ADC monitors multiple analog sensors (temperature, position), and PWM drives MOSFET gates for heating elements. The XLP features minimize quiescent draw on the vehicle battery. For under-hood or AEC-Q100-mandated applications, upgrade to the PIC16LF1783-E/SP extended-temperature variant or a dedicated automotive-grade PIC16F1xxx part.
おすすめ
Educational Development Boards
Through-hole SPDIP packages like the PIC16LF1783-I/SP remain the preferred choice for educational development boards, breadboard prototyping, and university curricula. The 0.300-inch (7.62 mm) pin spacing fits standard solderless breadboards, allowing students to build and modify circuits without specialized SMT tools. The PIC16LF1783's MPLAB X IDE compatibility, ICSP programming via a PICkit 4, and abundant community example code make it a strong teaching platform for embedded systems courses covering ADC, PWM, interrupts, and low-power design.

設計ノート
Decouple AVDD and VDD separately with 100 nF ceramic capacitors placed within 5 mm of the respective pins. Tie AVDD to VDD through a ferrite bead if the analog section experiences switching noise. For the lowest XLP sleep current, configure unused I/O as outputs driving low and disable unused peripherals via the PMD (Peripheral Module Disable) registers. Per Microchip's XLP family datasheet, typical sleep current with WDT off is below 100 nA at 3 V / 25 °C.
Route the analog signals (ANx, VREF+, VREF-) away from digital switching traces such as PWM outputs and oscillator pins. Provide a ground plane under the MCU and keep the crystal (if used) close to OSC1/OSC2 with short traces and a grounded guard ring. For ICSP, dedicate RB6/ICSPCLK and RB7/ICSPDAT to programming even in production boards, with a 4.7 kΩ pull-up on MCLR to VDD for clean in-circuit programming.
Do not assume the LF variant will run at 5 V - the PIC16LF1783-I/SP's absolute maximum VDD is 4.0 V and operation is specified 1.8 V-3.6 V. Exceeding this will damage the part. Also, the LF prefix does NOT mean the device is electrically identical to the 'F' variant - the LF has different brown-out and POR thresholds tuned for low-voltage operation. Always recompile firmware for the LF target in MPLAB X to ensure correct configuration bit values are programmed.
Estimated: at 32 MHz CPU clock, typical core supply current is 4 mA at 3.3 V (~13 mW). The 28-SPDIP package has θJA around 70 °C/W in still air, so junction temperature rise is well under 1 °C - no thermal management is required. Power dissipation scales with peripheral activity; when using PWM at high duty cycles on multiple outputs, verify the absolute maximum current ratings on each I/O pin (25 mA source/sink per pin, 200 mA total for the part) are not exceeded.
コンプライアンス情報
