PIC16C716T-04/SS 概要
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, working RAM, and peripheral interfaces such as timers, ADCs, and digital I/O. Within Microchip's taxonomy, the PIC16C716 belongs to the PIC16 family of 8-bit RISC microcontrollers, which sit between the smaller PIC12/16C5X baseline series and the higher-pin-count PIC17/PIC18 families. The "C" prefix indicates OTP (One-Time Programmable) EPROM program memory, positioning the PIC16C716 as a low-cost option for volume production where firmware is finalized at manufacturing time.
Key features of the PIC16C716T-04/SS include 35 single-word RISC instructions with 200ns instruction cycle at 20MHz, 13 digital I/O pins, an 8-channel 8-bit A/D converter (selectable as 4x8-bit channels in some configurations), Brown-out Detect/Reset, Power-on Reset, Watchdog Timer, PWM module, and Capture/Compare/PWM peripherals. The device operates from a 2.5V-5.5V supply and supports an industrial temperature range of -40C to +85C. The 20-SSOP package provides compact footprint while maintaining through-hole-equivalent I/O accessibility.
The PIC16C716 is built on Microchip's classic Harvard-architecture RISC core with separate program and data paths to enable single-cycle instruction execution (except program branches which take two cycles). The 8-bit data path and 14-bit instruction word enable efficient code density. The device includes a 4-channel 8-bit A/D converter with two additional timers and a capture/compare/PWM module, making it suitable for mixed-signal embedded control applications.
Typical applications include industrial automation controllers, motor control drivers, sensor signal conditioning, consumer electronics control boards, automotive body electronics, and HVAC control systems. The combination of on-chip ADC, PWM, and timers enables closed-loop control tasks without external signal conversion circuitry.
When designing with this device, note that OTP memory requires firmware commitment before manufacturing. For prototyping, consider the flash-memory equivalent PIC16F716 which shares the same pinout and peripherals. Ensure decoupling capacitors are placed within 5mm of the VDD pin and that the MCLR circuit is properly handled during in-circuit programming.

主な用途
PIC16C716T-04/SS の用途: 7 件s: Industrial Automation Controller, Motor Speed Control (PWM), Sensor Signal Conditioning, Consumer Electronics Control Board, HVAC Control Module, Automotive Body Electronics, Battery-Powered Remote Sensor Node.
Industrial Automation Controller
The PIC16C716T-04/SS suits industrial automation controllers because its 13 GPIO pins, on-chip 8-bit A/D converter with up to 4 input channels, and PWM module provide enough I/O and analog integration to read sensor signals and drive actuators without external ADC or DAC chips. At 4MHz instruction execution, the 200ns cycle time enables 5 MIPS throughput, which is sufficient for closed-loop control loops in PLCs, conveyor controllers, and process monitoring modules. The OTP memory makes per-unit cost optimal for factory-floor equipment produced at scale, while the industrial -40C to +85C temperature range tolerates cabinet environments.
おすすめ
Motor Speed Control (PWM)
The PIC16C716T-04/SS PWM peripheral generates variable-duty switching signals to drive DC motor H-bridges or single-phase brushless motor commutation logic. Combined with its 8-bit A/D converter, a feedback loop can sample a tachometer or back-EMF signal and adjust PWM duty cycle to maintain constant speed or torque. The PIC16C716's Capture/Compare/PWM module provides flexible timer-driven edge alignment with configurable frequency and resolution, supporting DC motor speed control, PWM fan controllers, and hobby servo positioning. Its 4MHz clock and 13 I/O pins cover most small-motor control boards with status indicators.
おすすめ
Sensor Signal Conditioning
The PIC16C716T-04/SS works well as a sensor signal conditioning front-end because its on-chip 8-bit A/D converter with up to 4 channels digitizes analog transducer outputs directly, eliminating external ADC components. Sensor types like thermistors, photodiodes, strain gauges (with bridge amplifier), and gas sensor analog outputs can be sampled at up to the device's ADC throughput rate. The 128-byte RAM accommodates moving averages and calibration constants. Combined with PWM or GPIO output, the PIC16C716 can produce a calibrated analog voltage, PWM duty cycle, or serial stream representing the conditioned sensor reading for downstream systems.
おすすめ
Consumer Electronics Control Board
The PIC16C716T-04/SS fits consumer appliance control boards including coffee machines, washing machine sub-controllers, microwave oven keypads, and small kitchen appliances. Its low-cost OTP memory aligns with consumer pricing pressure, while the 20-SSOP package keeps board footprint compact for crowded enclosures. The integrated PWM drives buzzers or LED indicators, the A/D reads user potentiometers or temperature sensors, and the GPIO matrix scans keypads. Industrial-grade temperature operation handles appliance interior environments. Brown-out detect and watchdog timer prevent lockup in unsupervised consumer environments.
おすすめ
HVAC Control Module
The PIC16C716T-04/SS supports HVAC thermostat and damper control modules because its 8-bit ADC reads multiple temperature sensors, its PWM outputs drive proportional damper motors or PWM-controlled fan stages, and its GPIO matrix interfaces with the user keypad and LCD. The industrial temperature rating (-40C to +85C) covers rooftop HVAC unit environments. Brown-out detect handles unstable line-derived DC rails, while the watchdog timer recovers from transient electrical disturbances common in HVAC installations. OTP memory reduces per-unit cost for high-volume residential HVAC deployments.
おすすめ
Automotive Body Electronics
The PIC16C716T-04/SS handles automotive body electronics like seat position controllers, mirror adjust modules, lighting controllers, and accessory timer modules. Its 13 GPIO pins drive relay logic, its ADC reads position feedback potentiometers, and its PWM modulates lighting fade rates or motor speeds. The 4MHz instruction cycle handles sequential control logic well. Note: automotive deployments should select the -04I/SS industrial-grade variant and may need AEC-Q100 compliance review. OTP memory locks firmware for the vehicle's lifetime, preventing post-production code tampering.
おすすめ
Battery-Powered Remote Sensor Node
The PIC16C716T-04/SS enables low-duty-cycle remote sensor nodes because it can sleep between samples and wake on timer overflow or external interrupt, then sample an analog sensor and transmit via GPIO bit-banging. With a 2.5V-5.5V supply range, the part runs from 2xAA cells or a small Li-ion. The Brown-out Detect function protects against cell exhaustion, while the Watchdog Timer wakes the MCU from sleep at periodic intervals. While not as low-power as modern dedicated nano-power MCUs, the PIC16C716T-04/SS is a viable choice for retrofit or low-volume sensor telemetry where cost and pin-compatibility with installed PIC16 designs matter.

主な差別化要因
- Same SSOP-20 footprint across entire PIC16C71x family （vs PIC16C711T-04/SS)
- OTP memory lowest unit cost for high volume （vs PIC16F716-I/SS)
- Industrial temperature grade option in same package （vs PIC16C716T-04/SS (standard))
設計ノート
OTP (One-Time Programmable) memory on the PIC16C716T-04/SS cannot be electrically erased - a programming error wastes the device. Verify firmware on a flash-based development equivalent (PIC16F716-I/SS, same SSOP-20 footprint) before committing to OTP production parts. For prototypes, use the windowed ceramic JW-package PIC16C716/JW which permits UV erasure during firmware iteration.
Place a 100nF ceramic decoupling capacitor within 5mm of the VDD pin (pin 16) to suppress digital switching noise. Add a bulk capacitor (10uF to 47uF tantalum or aluminum) at the board-level power input. The MCLR pin (pin 1) requires a 10k pull-up resistor to VDD for normal operation; for in-circuit programming add the standard ICSP connector with separate Vpp line.
If using the internal oscillator option, leave pin 8 (OSC1/CLKIN) and pin 9 (OSC2/CLKOUT) unconnected or route them to the oscillator network as documented. For crystal operation, place the crystal and load capacitors within 5mm of the OSC pins to minimize stray capacitance and EMI pickup. Analog inputs (RA0-RA3/AN0-AN3) should be routed away from digital switching lines and the PWM output to prevent ADC noise coupling.
