PIC16F15274-E/PT 概要
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory, volatile data memory, and a mix of analog and digital peripherals behind a set of general-purpose I/O pins. Within the broader taxonomy, an MCU sits under microcontroller -> embedded processor -> semiconductor device, and the PIC16F15274 occupies the 8-bit mid-range tier aimed at low-power, low-cost, deterministic control. The 'F' suffix denotes Flash program memory, allowing in-circuit re-programming for development and field updates.
Key features include 7 KB Flash (7K x 14 words), 512 bytes SRAM, 256 bytes EEPROM, a 10-bit ADC with internal voltage reference, two PWM modules, two Capture/Compare/PWM (CCP) peripherals, hardware limit timer (HLT), watchdog timer, Peripheral Pin Select (PPS), EUSART, SPI, and I2C. The device also carries Microchip's eXtreme Low-Power (XLP) technology for battery-driven designs, along with a 32 MHz internal oscillator that lets the BOM drop external crystals in many applications.
The PIC16F15274 uses a Harvard-architecture RISC core with a 14-bit instruction word, providing deterministic single-cycle execution for most instructions. The PPS module remaps digital peripherals onto a wide range of I/O pins, simplifying board layout when signal routing changes late in the design. The 10-bit ADC combined with internal voltage reference enables accurate sensor measurements without external analog components, while the HLT peripheral offloads timing-critical tasks from the CPU.
Typical applications include battery-powered sensor nodes, home appliances, LED lighting controllers, low-cost motor control, IoT edge nodes, and industrial sensor hubs. The combination of XLP sleep currents below 1 microamp and integrated peripherals makes the part well suited to mains-battery hybrids and energy-harvesting front ends.
When designing with the PIC16F15274-E/PT, take care with the decoupling network - place a 100 nF X7R plus a 10 uF bulk capacitor within 3 mm of the VDD pin. The 'E' temperature grade indicates -40C to +125C operation, so margin the clock and ADC reference for thermal drift at the extremes of the range.

主な用途
PIC16F15274-E/PT の用途: 6 件s: Battery-Powered Wireless Sensor Nodes, Home Appliance Control Boards, LED Lighting Controllers, Low-Cost BLDC and Small Motor Control, Industrial Sensor Hubs and Edge Aggregators, Consumer Remote Controls and HMI Panels.
Battery-Powered Wireless Sensor Nodes
The PIC16F15274-E/PT fits wireless sensor nodes because its eXtreme Low-Power (XLP) sleep current sits below 1 microamp while the 32 MHz PIC core wakes in microseconds to service interrupts. The 10-bit ADC with internal voltage reference digitizes temperature, humidity, or gas-sensor outputs without external analog parts, while PPS remaps the EUSART, SPI, and I2C onto any GPIO pin to simplify PCB routing to a sub-GHz radio. Battery life exceeds five years on a single CR2032 when duty-cycled to a 1 percent sample rate.
おすすめ
Home Appliance Control Boards
In washing machines, dishwashers, and microwave ovens, the PIC16F15274-E/PT provides the deterministic GPIO toggling and PWM control demanded by appliance makers. Two PWM channels drive motor or heater loads, while two CCP peripherals handle timing-critical input captures from Hall sensors or zero-cross detectors. The 44-pin TQFP exposes enough I/O for keypad, LCD, and buzzer interfaces, and the -40C to +125C E temperature grade survives the under-cabinet thermal environment of kitchen equipment.
おすすめ
LED Lighting Controllers
The PIC16F15274-E/PT is a strong fit for constant-current LED drivers because its two PWM modules plus two CCP peripherals deliver smooth dimming across multiple channels simultaneously. The Hardware Limit Timer (HLT) offloads flicker-free PWM generation from the CPU, freeing cycles for DALI, 0-10 V, or wireless DMX protocol handling via EUSART/SPI/I2C. The 10-bit ADC reads ambient light and thermistor feedback for closed-loop dimming and thermal foldback without external components.
おすすめ
Low-Cost BLDC and Small Motor Control
Sensorless or Hall-sensor BLDC fans, pumps, and small appliances can use the PIC16F15274-E/PT as a compact controller. The 32 MHz MIPS throughput executes Field-Oriented Control or trapezoidal commutation in real time, while the 10-bit ADC samples back-EMF or current-sense amplifiers for safe commutation. Peripheral Pin Select relocates the PWM outputs to any pin, easing PCB layout when the motor driver sits far from the MCU. E-grade thermal range handles motor-driver proximity heat.
おすすめ
Industrial Sensor Hubs and Edge Aggregators
For industrial sensor hubs aggregating Modbus RTU, I2C sensor, or 4-20 mA inputs, the PIC16F15274-E/PT offers the EUSART, SPI, and I2C needed to bridge multiple field buses. The 7 KB Flash stores Modbus map and calibration tables in EEPROM, while the 10-bit ADC reads analog field sensors directly. The -40C to +125C operating range and PPS flexibility suit DIN-rail mounted control cabinets with mixed-signal wiring.
おすすめ
Consumer Remote Controls and HMI Panels
The PIC16F15274-E/PT drives low-cost remote controls, IR blasters, and small HMI panels thanks to its EUSART for IR modulation, 10-bit ADC for battery voltage monitoring, and XLP sleep that extends coin-cell life in handheld devices. PPS remaps the IR carrier to any timer-capture-capable pin, while the 32 MHz core handles button-debounce and protocol encoding. The 44-pin TQFP supports segmented LCD, keypad matrix, and buzzer interfaces for richer wall-mounted controllers.

設計ノート
Place a 100 nF X7R 0603 ceramic decoupling capacitor within 3 mm of each VDD pin, with a 10 uF X5R bulk capacitor on the same supply trace. For battery-powered designs, route the bulk capacitor through a ferrite bead to suppress HFINTOSC harmonics from coupling into the analog rail. The PIC16F15274-E/PT's XLP sleep current below 1 microamp makes it suitable for years-long battery life when the firmware minimizes wake events.
The TQFP-44 package has a thermal resistance around 50 C/W (theta_JA) on a standard 4-layer JEDEC test board, but in a real enclosure with limited airflow the effective theta_JA can climb to 70-90 C/W. Because the E grade operates to +125C, derate the clock frequency above +85C if HFINTOSC accuracy drifts beyond your timing budget. Always place a thermal via array under the exposed pad (when present) or directly under the die shadow for better heat spreading.
Use Peripheral Pin Select (PPS) to remap EUSART, SPI, and I2C onto convenient GPIO pins, but keep analog and digital signals separated to avoid ADC coupling. Route the OSC1/OSC2 traces as a short differential pair with a ground guard on each side if the system is noise-sensitive. Always include a 10 kohm pull-up on MCLR and a 100 nF cap on the MCLR line to avoid spurious resets during power-up.
Do not assume the internal 32 MHz oscillator is accurate enough for UART communication - HFINTOSC drifts 1-2 percent across temperature, which fails 16-bit UART timing at higher baud rates. Either calibrate against the EUSART baud-rate register or switch to an external crystal for UART-bound applications. Also confirm the BOR (Brown-Out Reset) voltage is configured for the actual VDD range; leaving it at the default 2.85 V can cause code lockup on slow-rising supplies.
