PIC16F819-I/SOTSL 概要
An 8-bit microcontroller (MCU) is a programmable processor built around an 8-bit data path that integrates CPU core, non-volatile program memory, working RAM, and a curated set of peripherals onto a single IC. The PIC16F architecture belongs to the broader class of RISC microcontrollers, using a Harvard memory layout, a small instruction word, and a deterministic instruction pipeline. Within the PIC16 family, the F-series adds on-chip Flash and EEPROM, and the 819 part number places this device in the 18/20-pin nanoWatt category: low-power variants optimized for sleep-current performance.
Key features include 200 ns instruction execution, a wide 2.0 V to 5.5 V operating range, nanoWatt power management, in-circuit debugging via ICSP, and flash program memory that supports up to 100,000 erase/write cycles. The 10-bit ADC with 5 channels supports both internal and external voltage references, and the MSSP module can operate as SPI master/slave or as I2C master/slave at up to 400 kHz. Brown-out Reset (BOR) and Power-on Reset (POR) provide fail-safe startup.
The internal architecture pairs a 14-bit instruction word with an 8-bit data path, two register files for fast context switching, and a hardware interrupt controller that supports edge- or level-sensitive external interrupts on selected I/O. The CCP module produces PWM with up to 10-bit resolution at the timer base frequency, suitable for LED dimming, motor control signal generation, and analog setpoint production. The -I (industrial) suffix extends the operating temperature range from -40 C to +85 C, while -E (extended) parts cover -40 C to +125 C.
Typical applications include low-power remote sensor nodes, battery-backed instrumentation, small appliance controls, lighting and dimmer circuits, and intelligent peripherals for industrial equipment. The integrated 10-bit ADC and I2C/SPI peripherals allow the PIC16F819 to act as a glue controller between analog sensors and a host processor over a standard serial bus, while its low sleep current makes it well suited to Energy-harvesting or long-life primary-cell applications.
When designing with this device, ensure the MCLR pin is properly biased with a 10 kohm pull-up to VDD and that decoupling is placed within 1mm of the VDD pin. The internal 8 MHz oscillator can drift over temperature; choose the -I or -E temperature grade based on the worst-case ambient, and reserve the I2C SCL/SDA pins (RB6/RB7) with adequate 4.7 kohm pull-ups if the bus is shared with other devices.

主な用途
PIC16F819-I/SOTSL の用途: 6 件s: Battery-Backed Remote Sensor Node, Industrial Lighting Dimmer Controller, Small Appliance Control Board, Intelligent Peripheral with SPI/I2C Interface, Automotive Body Electronics Sub-Module, Consumer Hobbyist and Educational Platform.
Battery-Backed Remote Sensor Node
The PIC16F819-I/SOTSL suits battery-backed remote sensor nodes because its nanoWatt Sleep mode drops quiescent current below 1 uA typical, allowing multi-year battery life when waking briefly to digitize a sensor reading. Its 5-channel 10-bit ADC handles temperature, voltage, and analog signal conditioning at sub-mW average power, while the I2C/SPI master peripheral connects to digital sensors such as accelerometers or humidity ICs. The 256-byte EEPROM provides reliable storage for calibration coefficients without external non-volatile memory, and the 20 MHz CPU throughput sufficient for digital filter preprocessing before low-power sleep. Power dissipation remains under 30 mW even at full 20 MHz and 5 V, well within the SOIC-18 thermal limit of approximately 1 W on standard JEDEC EIA/JESD 51 test boards.
おすすめ
Industrial Lighting Dimmer Controller
The PIC16F819-I/SOTSL fits lighting dimmer controllers thanks to its Capture/Compare/PWM (CCP) module that produces 10-bit PWM at the Timer2 base frequency, enabling smooth 0-100% dimming curves for LED fixtures and incandescent loads. Its 16 I/O pins can drive multiple channels of MOSFET gates or triac optocouplers for AC line dimming, while the analog comparator and ADC verify zero-cross timing for phase-angle control. The 2.0 V to 5.5 V VDD range simplifies power supply design across 3.3 V and 5 V logic levels, and the -40 C to +85 C industrial temperature rating supports industrial lighting environments. Power dissipation at 5 V and 20 MHz is approximately 30 mW, leaving substantial thermal budget for the SOIC-18 package.
おすすめ
Small Appliance Control Board
The PIC16F819-I/SOTSL serves small appliance control boards (coffee makers, fans, kitchen timers) because its CCP module drives TRIAC gates for heater elements and motor windings, while its 10-bit ADC monitors NTC thermistors for closed-loop temperature control. Its Flash memory supports in-the-field firmware updates through ICSP, simplifying manufacturing bring-up timelines for small batch production. The 35 single-word instruction set makes assembly programming efficient for time-deterministic motor-control loops, and the 256-byte RAM handles PWM duty-cycle arithmetic without external memory. Power dissipation at 5 V and 20 MHz is approximately 30 mW, well within the SOIC-18 thermal limit on a 1 square inch copper pour.
おすすめ
Intelligent Peripheral with SPI/I2C Interface
The PIC16F819-I/SOTSL acts as an intelligent peripheral for larger systems because its main Slave Control Port can be configured as SPI or I2C, allowing it to appear as a co-processor on a system bus while exposing its 5-channel 10-bit ADC, CCP PWM output, and digital I/O to the host. This makes it useful for distributed control nodes where the main processor handles HMI but delegates analog sampling and PWM generation to a PIC16F819. Its nanoWatt Sleep mode allows the peripheral to remain quiescent until the host requests a reading, conserving system power budgets in industrial and IoT applications. Power dissipation at 5 V and 20 MHz is approximately 30 mW, manageable in the SOIC-18 package.
おすすめ
Automotive Body Electronics Sub-Module
The PIC16F819-I/SOTSL handles automotive body sub-modules (seat controllers, mirror adjusters, ambient lighting) because its 16 I/O pins drive relay coils and sense switch contacts, while its 10-bit ADC monitors the 12 V battery rail through a resistive divider. The -40 C to +85 C industrial temperature rating covers cabin environments, though for under-hood applications a PIC16F819-E/SO (extended -40 C to +125 C) is preferred for thermal margin. Its I2C/SPI peripheral connects to sensor clusters, and its CCP module drives PWM-controlled LED strings for ambient lighting. Power dissipation at 5 V and 20 MHz is approximately 30 mW, and the SOIC-18 footprint withstands typical automotive shock and vibration profiles per JEDEC JESD22-B103B.
おすすめ
Consumer Hobbyist and Educational Platform
The PIC16F819-I/SOTSL is well suited to hobbyist and educational projects because of its low cost, broad Microchip MPLAB X IDE support, and free XC8 compiler availability. Its 35-instruction PIC16 instruction set is pedagogically clean and well documented, making it an excellent teaching vehicle for register-level programming and interrupt-driven design. The 18-SOIC footprint is breadboard-friendly with SOIC-to-DIP adapters, and the ICSP interface allows students to flash firmware without removing the part. The 256-byte EEPROM stores user preferences in hobbyist projects such as custom game controllers, electronic dice, and simple data loggers. Power dissipation at 5 V and 20 MHz is approximately 30 mW in the SOIC-18 package.

設計ノート
The PIC16F819-I/SOTSL nanoWatt Sleep mode reduces quiescent current below 1 uA typical when the CPU is halted but peripherals can be configured to wake the device on Timer1 overflow or external interrupts. Place a 100 nF ceramic decoupling capacitor within 1 mm of the VDD pin and a 10 uF bulk capacitor at the regulator output. Avoid drawing >200 mA peak from VDD on the SOIC-18 package; sustained current above 100 mA requires substantial copper pour to stay below the 150 C junction temperature limit.
Route the MCLR pin with a 10 kohm pull-up to VDD and place a 0.1 uF capacitor from MCLR to VSS within 1 mm of the pin to ensure monotonic rise < 1 ms for clean Power-on Reset. Keep the crystal or resonator traces within 5 mm of the OSC1/OSC2 pins and surround them with a grounded guard trace to reduce EMI susceptibility. Connect all VSS pins (pin 8 in SOIC-18) to a low-impedance ground pour for thermal dissipation and ESD return path. Per JEDEC EIA/JESD 51, the SOIC-18 thermal resistance theta_JA is approximately 80 C/W on a standard 1 oz 4-layer test board.
The PIC16F819-I/SOTSL main Slave Control Port (SSP) operates as either SPI master/slave at up to 10 MHz (Fosc/4) or I2C master/slave at 100 kHz Standard-mode and 400 kHz Fast-mode. For I2C bus sharing, add 4.7 kohm pull-ups to VDD on SCL (RC3) and SDA (RC4) to meet Fast-mode rise/fall time limits. For SPI, ensure the master SCK frequency does not exceed Fosc/4 (5 MHz at 20 MHz Fosc) and use series resistors near the source to dampen ringing on long PCB traces.
Do not assume the PIC16F819 8 MHz internal oscillator is accurate over temperature; it typically drifts +/- 2% from -40 C to +85 C, which is inadequate for UART timing or precise timing applications - use an external crystal when accuracy matters. The -I (industrial) suffix covers -40 C to +85 C; for designs that may exceed +85 C ambient, switch to the -E (extended) PIC16F819-E/SO variant. The A/D converter requires a 2-channel minimum acquisition time of approximately 20 us at 5 V; failure to wait the full acquisition window corrupts conversion results.
