PIC16F726T-I/SS 概要
A PIC (Peripheral Interface Controller) microcontroller is a Harvard-architecture 8-bit MCU with on-chip flash, EEPROM, RAM, peripherals, and a CPU optimized for deterministic embedded control. PIC microcontrollers sit in the broader hierarchy of microcontrollers -> microprocessors -> semiconductor ICs. Microchip's PIC16F series occupies the mid-range (PIC16) tier, which adds richer peripherals, more memory, and C-optimized architectures over the baseline PIC10/12/14 families, while keeping the instruction-set simplicity that made the PIC architecture popular for low-power and motor/lighting control.
Key features of the PIC16F726T-I/SS include nanoWatt XLP technology for sub-microamp sleep currents, an integrated 8-channel 8-bit ADC with on-chip voltage reference, multiple timers (Timer0, Timer1, Timer2), enhanced PWM/capture/compare peripherals, and a wide 1.8V to 5.5V operating voltage range. It supports in-circuit serial programming (ICSP) and self-programming via flash program memory.
Typical applications include home-automation sensor nodes, battery-powered wireless transmitters, white-goods control boards, lighting sub-system entry, low-power metering, and general-purpose embedded logic. The wide voltage range and very low sleep current make it attractive for IoT end nodes and energy-harvesting systems where quiescent draw dominates battery life. The 28-SSOP footprint also suits compact designs in industrial control panels.
When designing with this device, select the lowest practical clock speed in active mode and keep the MCU in sleep between events; nanoWatt XLP gives the most benefit when firmware stays in sleep for >90% of the duty cycle. Use the internal 16MHz HFINTOSC when timing tolerance allows, and select a slower LFINTOSC for sleep wake-up timing. For firmware development, MPLAB X IDE plus the XC8 compiler is the canonical toolchain; no external programmer is required if ICSP header pins are exposed.

PIC16F726T-I/SS の用途: 7 件s: Battery-Powered IoT Sensor Node, Home Appliance Control Board, LED Lighting Controllers, Portable Handheld Instruments, Automotive Sub-System Interior Modules, Wireless Remote Control / RF Key Fob Transmitters, Industrial Sensor Signal Conditioning.
Battery-Powered IoT Sensor Node
The PIC16F726T-I/SS's nanoWatt XLP technology with sub-microampere sleep current makes it ideal for battery-powered IoT sensor nodes that wake briefly to sample and transmit, then return to sleep. The 1.8V-5.5V Vdd range accommodates single-cell lithium, two-AA alkaline, or 3.3V coin-cell chemistries without level shifters. The 8-channel 8-bit ADC handles typical sensor inputs (temperature, light, gas) directly, while the 14KB flash accommodates firmware stacks including MPLAB XC8 C code, simple drivers, and a small wireless-protocol state machine. With 20MHz maximum CPU speed and HFINTOSC, sensor reads and conditional wake decisions execute fast enough that average current stays below 50uA in typical duty-cycled scenarios.
おすすめ
Home Appliance Control Board
With its enhanced CCP/PWM peripherals, the PIC16F726T-I/SS drives TRIAC-controlled AC loads, brushed DC motors, or MOSFET-driven relays in white-goods and small appliances. The 8-channel 8-bit ADC multiplexes button inputs, NTC thermistors, and current-sensing shunts through a single MCU, reducing external component count. The 20MHz CPU speed handles real-time control loops for thermostats, washing-machine motor sequencing, or coffee-machine heating profiles. Industrial -40C to +85C rating supports the temperature profile inside appliance housings, and 14KB flash comfortably fits state machines and UI handling for entry-level to mid-range products.
おすすめ
LED Lighting Controllers
The PIC16F726T-I/SS powers sub-system entry in RGB, tunable-white, or single-channel LED controllers, using its enhanced CCP/PWM modules to generate accurate dimming LED drivers. Multiple PWM channels allow independent control of red, green, and blue channels or color-temperature mixing in white-light fixtures. With 1.8V-5.5V operation, the device interfaces directly with 3.3V LED-driver ICs or with logic-level MOSFETs at 5V, while nanoWatt XLP extends product lifetime in always-on wireless or capacitive-touch wake applications. 14KB flash supports DALI, 0-10V, or proprietary dimming protocols along with color-state management.
おすすめ
Portable Handheld Instruments
Low-power handheld instruments such as digital thermometers, humidity meters, and basic multimeters benefit from the PIC16F726T-I/SS's nanoWatt XLP sleep mode and ADC integration. The 8-channel 8-bit ADC multiplexes multiple sensor inputs with low-quiescent op-amps, while the 28-SSOP package fits inside compact enclosures. Wide Vdd operation allows direct connection to 3V coin cells or USB-derived 5V rails. The 14KB flash supports measurement firmware, calibration tables, and basic UI handling, including button-debounce logic and LCD segment driving through external drivers.
おすすめ
Automotive Sub-System Interior Modules
Within cabin-interior modules such as ambient lighting controllers, seat-fan occupancy switches, or accessory-driven HVAC interfaces, the PIC16F726T-I/SS handles PWM outputs, ADC inputs from NTC or rotary encoders, and LIN-style UART communication through software bit-banging. Its 28-SSOP package fits PCB-constrained interiors, and the -40C to +85C industrial grade covers most cabin conditions. With 14KB flash and 20MHz core, firmware supports calibration tables, lighting sequences, and diagnostic state machines. For under-hood or AEC-Q100 strict-compliance applications, consider the automotive-grade PIC16F counterpart.
おすすめ
Wireless Remote Control / RF Key Fob Transmitters
Key-fob and wireless remote transmitters depend on absolute minimum sleep current, and the PIC16F726T-I/SS's nanoWatt XLP feature delivers sub-microampere quiescent current that extends coin-cell battery life to multi-year levels. The 20MHz CPU wakes quickly to drive ASK/FSK encoder sequences for sub-GHz or 2.4GHz transmitters via SPI/UART, while the 8-bit ADC handles potentiometer or directional-pad analog inputs in higher-end fobs. 14KB flash fits custom rolling-code protocols, button mapping, and LED indicator logic. SSOP package supports miniaturized PCB designs.
おすすめ
Industrial Sensor Signal Conditioning
In factory-automation and process-control sub-systems, the PIC16F726T-I/SS conditions analog sensor inputs and forwards digital data to a host PLC or gateway. Its 8-channel 8-bit ADC multiplexes multiple analog process variables (pressure, flow, temperature) into a single MCU, while PWM outputs control proportional valves or heater elements. nanoWatt XLP reduces cabinet cooling requirements in always-on industrial systems, and the 28-SSOP package's industrial-grade thermal range supports -40C to +85C cabinet environments. Wide Vdd operation tolerates 24V-derived industrial rails with simple regulator ICs.

設計ノート
Estimated: at Vdd=3.3V, full 20MHz active CPU, IO loaded lightly, the PIC16F726T-I/SS draws approximately 2-3 mA active. In sleep mode with peripherals disabled, nanoWatt XLP drops this to under 100 nA. For battery-powered designs, keep the MCU in sleep for >90% of the duty cycle and wake only via Watchdog Timer or external interrupt to maximize battery life. Use HFINTOSC for fast wake, then switch to LFINTOSC for low-power waiting periods.
Place a 100nF decoupling capacitor as close as possible to the Vdd pin (pin 6) and a second 100nF near the Vss pins (7 and 28). For analog accuracy, add a 10uF bulk capacitor near the Vdd pin and a separate analog AVdd pin decoupling capacitor if used. The 28-SSOP package has 0.65mm pitch; ensure solder paste stencil apertures meet IPC-7525 standards for fine-pitch SSOP, and avoid ground-plane cuts under the IC body to minimize thermal stress and EMI.
Route the ICSP clock (RB6/ICSPCLK) and data (RB7/ICSPDAT) signals with short, direct traces to a 6-pin ICSP header (or test pads) for in-circuit programming and debugging. Keep the MCLR/VPP line separate from any high-current switching traces and include a 10k pull-up to Vdd to ensure reliable reset. If the MCLR pin is unused as reset, configure it as digital input with internal pull-up disabled to avoid spurious resets from noise.
For ADC measurements above 1% accuracy, use the on-chip voltage reference or an external low-noise reference such as the MCP1501. Avoid toggling digital I/O on adjacent pins during ADC conversions, and oversample digitally in software to improve effective resolution. Place the analog input traces over a continuous ground plane and keep digital traces away from analog signal paths.
Do not exceed 5.5V on Vdd or apply voltage to any pin before Vdd is applied (latch-up risk on CMOS I/O). The "/SS" suffix indicates 28-SSOP package; verify the PCB footprint matches SSOP 0.65mm pitch, not SOIC 1.27mm pitch. The "I" in -I/SS indicates industrial -40C to +85C temperature range; for AEC-Q100 automotive applications, use the automotive-graded PIC16F equivalent from the same family.
