PIC16F716-I/SO 概要
An 8-bit microcontroller is a single-chip computing device built around an 8-bit data path, combining CPU core, non-volatile program memory, working RAM, I/O peripherals and timers on one silicon die. The PIC16F family belongs to Microchip's mid-range architecture hierarchy - above the baseline PIC10/12/14 families but below the enhanced PIC18 and PIC24/dsPIC families. It uses a RISC instruction set with only 35 single-word instructions and an 8-level hardware stack, which keeps firmware shallow, deterministic and easy to debug in real-time control loops.
Key features include four 8-bit ADC channels, two additional timers beyond the core Timer0/Timer1 pair, an enhanced Capture/Compare/PWM (ECCP) peripheral, an internal oscillator option, and a wide 2.0-5.5 V supply range. The ECCP module supports PWM output for motor control and bridge-drive applications, complementing the 8-bit ADC for closed-loop analog sensing.
The PIC16F716 is built on Microchip's mature mid-range 14-bit instruction core with Flash program memory, allowing in-circuit serial programming (ICSP) and in-application updates without removing the part. The wide operating voltage window, internal oscillator and hardware PWM/ADC resources make it well suited to cost-sensitive mixed-signal designs.
Typical applications include white-good and small-appliance motor control, automotive body and lighting modules, industrial sensor signal conditioning, consumer remote controls, LED driver boards, and battery-powered instrumentation. Industrial-grade -40C to +85C operation (denoted by the 'I' suffix) allows use in harsher enclosures. Choose the PIC16F716 when you need a true 8-bit, low-cost MCU with integrated ADC and ECCP PWM rather than the larger PIC18F or PIC16F1xxx devices.
When designing with this part, place a 100 nF decoupling capacitor as close as possible to VDD/VDDCORE and another on AVSS, configure unused I/O pins as outputs to minimise sleep current, and reserve the MCLR pin for in-circuit serial programming access during board bring-up.

主な用途
PIC16F716-I/SO の用途: 6 件s: White-Good / Small-Appliance Motor Control, Automotive Body and Lighting Modules, Industrial Sensor Signal Conditioning, Consumer Remote Controls and IR Transmitters, LED Driver and Sign Boards, Battery-Powered Instrumentation and Data Loggers.
White-Good / Small-Appliance Motor Control
The PIC16F716-I/SO is well suited to small-appliance motor control such as washing-machine drain pumps, dishwasher circulation pumps and refrigerator fans, where cost dominates the BOM and 8-bit performance is sufficient. Its Enhanced CCP (ECCP) module generates the centre-aligned PWM used for triac-style or MOSFET-bridge commutation, and the 4-channel 8-bit ADC samples motor current, NTC thermistor temperature and tachometer feedback for closed-loop control. With 3.5 KB of Flash and the 35-instruction mid-range core, a complete 6-step BLDC or single-phase AC fan control routine fits comfortably, and the 2.0-5.5 V supply range lets the same firmware run from 3.3 V logic or 5 V regulated rails without redesign.
おすすめ
Automotive Body and Lighting Modules
The PIC16F716-I/SO targets entry-level automotive body and lighting applications such as interior LED drivers, turn-signal repeaters, ambient lighting controllers and door-module LED dimming. The 8-bit ADC measures ambient light via a photodiode or potentiometer for smooth dimming, while the ECCP PWM peripheral drives a constant-current LED buck or boost stage with adjustable duty cycle. The industrial -40C to +85C temperature window covers under-dash and cabin environments, and the wide 2.0-5.5 V supply handles 12 V automotive rails after regulation. For under-hood modules above +85C, step up to the PIC16F716-E variant with the -40C to +125C extended temperature grade.
おすすめ
Industrial Sensor Signal Conditioning
The PIC16F716-I/SO is a natural fit for industrial sensor-conditioning modules that read 0-5 V analog transducers and emit a digital UART or PWM output. The 4-channel 8-bit ADC multiplexes thermocouple amplifiers, pressure transducers and 4-20 mA loop signals at up to 8-bit resolution - adequate for threshold-detection and basic linearisation in panel meters and process controllers. The 35-instruction RISC core and 5 MIPS throughput handle simple linearisation lookup tables and UART communication at 9600-115200 baud without OS overhead, and the in-circuit serial programming (ICSP) interface lets field technicians reflash calibration firmware in installed equipment.
おすすめ
Consumer Remote Controls and IR Transmitters
The PIC16F716-I/SO is a cost-optimised solution for IR/RF remote controls, wireless key fobs and consumer remote-control transmitters where BOM cost under USD 1.50 is essential. The 13 I/O pins drive key-matrix scanning up to 6x6, while the on-chip timer resources generate the 38 kHz / 40 kHz carrier for IR LED modulation without external logic. The 2.0-5.5 V supply window lets the same firmware run on a single CR2032 coin cell (3 V) or two AA cells (3 V), and the mid-range core keeps firmware ROM and RAM usage under tight limits.
おすすめ
LED Driver and Sign Boards
The PIC16F716-I/SO drives small LED sign boards, decorative lighting strips and RGB pixel controllers that need moderate PWM resolution at low BOM cost. The ECCP module provides a hardware PWM channel for LED dimming or RGB colour mixing, while firmware-driven bit-banging on additional I/O pins extends the channel count through Charlieplexing. The 8-bit core keeps reaction-time readable on inexpensive LEDs at typical 100 Hz refresh, and 3.5 KB of Flash stores look-up tables for gamma correction, breathing effects and sequenced colour patterns without external memory.
おすすめ
Battery-Powered Instrumentation and Data Loggers
The PIC16F716-I/SO is appropriate for low-power, battery-driven instrumentation such as handheld thermometers, portable data loggers and field measurement tools. The wide 2.0-5.5 V supply supports 2xAA alkaline, single Li-Ion or USB-derived 5 V rails without additional regulators, and the mid-range core's low-power sleep modes combined with the on-chip ADC enable periodic sensor sampling at microamp-level standby current. The 3.5 KB Flash stores compression-free datalogging routines for days of buffered measurements, and the in-circuit serial programming (ICSP) interface allows firmware updates via a 5-pin header without opening the enclosure.

設計ノート
Estimated: Place a 100 nF ceramic decoupling capacitor within 5 mm of the VDD pin (pin 14 cluster) and a bulk 10 uF tantalum or ceramic on the main supply rail. Add a 10 uF + 100 nF combination on the AVdd pin if used, and a separate 100 nF on the AVss pin to keep ADC reference noise isolated from digital switching. A bulk reservoir of 47-100 uF is recommended if the source is a low-power LDO. Never share ADC analog ground with switching-node ground returns.
Route the ICSP signals (MCLR/VPP, RB6/PGC, RB7/PGD - on this device MCLR is pin 1 and the PGC/PGD functions share with the RA4/RA5 pins or via the USART module) to a 5-pin header placed at the board edge for production programming. Keep the trace to MCLR short and add a 10 kohm pull-up to VDD. Reserve the ICSP pins in firmware so the programmer can drive them without contention.
Do not leave unused I/O pins floating - configure them as outputs (drive low) to minimise sleep current and avoid shoot-through. The PIC16F716's RA4 is open-drain and requires an external pull-up if used as a digital output. Watch the ADC acquisition time: at 20 MHz / 5 MIPS, the 8-bit conversion requires ~12 Tad cycles - set the ADC clock prescaler so Tad is at least 1.6 us. Avoid using MCLR as a digital input without a proper pull-up.
