PIC16LC717-I/SS 概要
An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path, integrating a CPU core, program memory, RAM, peripherals, and I/O on one die. The PIC16C/PIC16LC architecture belongs to the broader family of microcontrollers -> embedded controllers -> semiconductor ICs, and Microchip's PIC line is the industry's most widely deployed 8-bit RISC MCU family. The 'LC' variant denotes a low-voltage / low-power member designed for 3.3 V nominal supplies, distinguishing it from the standard 'C' family.
Key features include 20 MHz operation, 14-bit wide instructions, 35 single-word instruction set, 200 ns instruction execution time, an integrated 10-bit Analog-to-Digital Converter with multiple channels, two additional timers, a Universal Synchronous Asynchronous Receiver Transmitter (USART) port, and low-power Sleep mode with wake-up on interrupt. The 20-SSOP package offers a compact 5.30 mm body suitable for space-constrained designs while still exposing all 16 I/O pins.
The PIC16LC717-I/SS is specified for an industrial temperature range of -40C to +85C, operates from 3.0 V to 5.5 V supply, and supports in-circuit serial programming (ICSP) via two pins. The architecture is upwards compatible with the PIC16C5X baseline and PIC12CXXX mid-range devices, allowing existing firmware and toolchains to migrate easily to this part.
Typical applications include industrial control front-ends, sensor signal conditioning, low-power embedded control, battery chargers, smart sensors, motor control signal logic, and consumer appliances requiring analog sensing and moderate throughput. The integrated ADC removes the need for an external converter in many sensor-interface designs.
When designing with this device, ensure decoupling capacitors are placed within 5 mm of VDD/VSS, follow Microchip's recommended ICSP layout for programming header placement, and validate worst-case ADC acquisition time against the chosen source impedance. Because the device is OTP (not flash), firmware must be fully verified before programming.

主な用途
PIC16LC717-I/SS の用途: 7 件s: Industrial Sensor Interface, Battery-Powered Embedded Control, Consumer Appliance Control, Automotive Body Electronics, Smart Sensor Hub, Motor Control Signal Logic, Low-Cost Educational / Hobby Platform.
Industrial Sensor Interface
The PIC16LC717-I/SS is well suited for industrial sensor-interface front-ends where the integrated 10-bit multi-channel ADC and 16 I/O pins reduce BOM cost. Operating from 3.0 V to 5.5 V, it can directly interface with 4-20 mA loop-powered transmitters, thermocouples (via external amplification), and bridge sensors. The 20 MHz core provides 200 ns instruction execution, enabling real-time linearization and filtering. Industrial temperature grade (-40C to +85C) covers most factory-floor environments. The OTP program memory locks firmware once production starts, preventing field tampering. The 20-SSOP package supports compact DIN-rail-mounted sensor modules where PCB real estate is constrained, and ICSP allows final calibration programming after sensor assembly.
おすすめ
Battery-Powered Embedded Control
The PIC16LC717-I/SS is ideal for battery-powered embedded control thanks to its 'LC' low-voltage design that operates from 3.0 V to 5.5 V and includes a low-power Sleep mode with interrupt wake-up. Sleep current drops to microamp levels, allowing coin-cell or Li-ion battery designs to last years. The integrated 10-bit ADC can monitor battery voltage directly without external circuitry, and the 16 I/O pins support key scanning, LED driving, and serial communication. The 200 ns instruction execution at 20 MHz enables rapid wake-and-process cycles before returning to Sleep. OTP memory locks firmware permanently, eliminating accidental reprogramming that could brick deployed devices in the field.
おすすめ
Consumer Appliance Control
The PIC16LC717-I/SS fits consumer appliance control boards (coffee makers, washing machines, microwave ovens, HVAC controls) where its 16 I/O pins drive relays, triac triggers, keypads, and LED indicators while reading sensors via the integrated 10-bit ADC. The 35-instruction RISC core is easy to program in C or MPLAB X IDE, shortening development time. Industrial temperature grade handles under-cabinet heat, and the 20-SSOP package suits slim appliance form factors. USART connectivity enables diagnostic serial ports or modem links for smart appliances. OTP memory locks the firmware image once product safety certification is complete, preventing field tampering that could violate regulatory limits.
おすすめ
Automotive Body Electronics
The PIC16LC717-I/SS supports non-safety automotive body electronics such as interior lighting controllers, seat-position memory, mirror adjustment modules, and accessory timers. The 16 I/O pins handle switch inputs, PWM-driven LED strings, and serial communication with body control modules. Operating from 3.0 V to 5.5 V tolerates typical 12 V battery systems with simple pre-regulators. The 10-bit ADC reads potentiometers and current-sense amplifiers for position feedback. Note that AEC-Q100 qualification is NOT specified for this part, so it is appropriate for non-safety body modules only. For safety-critical or powertrain applications, choose AEC-Q100-qualified PIC16F counterparts.
おすすめ
Smart Sensor Hub
The PIC16LC717-I/SS functions as a low-cost smart sensor hub aggregating multiple analog and digital sensors onto a single I2C/SPI bus. The 10-bit ADC reads up to multiple analog channels, while the USART handles communication with a host processor or wireless module. The 256-byte RAM is sufficient for sensor data buffering, and the 3.5 KB OTP program memory holds calibration tables and linearization routines. Industrial temperature grade supports outdoor sensor deployments. ICSP allows calibration coefficients to be programmed per-unit after final assembly, improving accuracy across sensor lots. The 20-SSOP package integrates cleanly into small sensor node PCBs.
おすすめ
Motor Control Signal Logic
The PIC16LC717-I/SS is well suited as a low-cost logic controller that generates timing signals, direction logic, and speed references for small DC motor drivers and stepper motor controllers. The integrated timers produce PWM outputs for motor speed control, while the 10-bit ADC reads back-EMF or current-sense signals for closed-loop control. The 16 I/O pins drive enable lines, fault inputs, and H-bridge direction signals. Operating from 3.0 V to 5.5 V simplifies integration with 3.3 V logic-level drivers. The 20 MHz core delivers deterministic 200 ns instruction execution for accurate PWM timing. OTP memory locks motor calibration parameters permanently, preventing field drift in production motor controllers.
おすすめ
Low-Cost Educational / Hobby Platform
The PIC16LC717-I/SS works well in educational and hobby electronics projects because of its simple 35-instruction RISC architecture, easy-to-learn assembly language, and free MPLAB X IDE toolchain from Microchip. The 20-SSOP package is breadboard-friendly with SSOP-to-DIP adapter boards, and ICSP programming requires only two pins plus VDD/VSS. Students can experiment with ADC sampling, USART communication, timer interrupts, and GPIO control. The 16 I/O pins support LED arrays, button inputs, and sensor connections. The 3.0 V-5.5 V supply range allows direct USB-powered operation. For iterative learning, PIC16F716 (same SSOP pinout, reprogrammable flash) is often preferred; the PIC16LC717-I/SS suits projects where final code is locked before deployment.

設計ノート
Decouple VDD (pin 14) with a 100 nF ceramic capacitor placed within 5 mm of the pin, plus a bulk 10 uF tantalum or aluminum electrolytic capacitor on the same rail. The PIC16LC717 draws brief current spikes during instruction execution; insufficient decoupling can cause VDD droops that trigger brown-out resets or ADC inaccuracies. For battery-powered designs, place the MCU in Sleep mode whenever possible and wake on interrupt to minimize average current draw to single-digit microamps.
Route the ICSP clock (RB6) and ICSP data (RB7) lines with short, direct traces to the programming header. Avoid routing high-current signals or switching nodes near the oscillator pins (OSC1/OSC2). Place the MCLR pull-up resistor (typically 10 kohm) close to the MCLR pin and consider adding a 100 nF capacitor to VDD if the programming environment is electrically noisy. For crystal oscillator designs, keep the crystal and load capacitors within 5 mm of OSC1/OSC2 to minimize parasitic capacitance.
Because the PIC16LC717-I/SS uses One-Time-Programmable memory, firmware bugs cannot be fixed after programming - the device must be discarded. Always program a small engineering pilot batch first, verify operation across temperature and voltage corners, then commit to volume orders. Additionally, do not exceed absolute maximum ratings: VDD must stay below 6.5 V and all I/O pin voltages must remain within -0.3 V to VDD+0.3 V to avoid latch-up. ESD precautions during handling are important since OTP devices are field-non-recoverable.
The 10-bit ADC requires adequate acquisition time based on source impedance - per the PIC16C717 datasheet, source impedance above 10 kohm requires additional acquisition delay or a buffer op-amp. Place a 100 nF ceramic bypass capacitor directly at each analog input pin to filter high-frequency noise. For accurate ADC readings in mixed-signal designs, route analog signals away from switching traces (PWM outputs, relay drivers) and consider a ground plane partition between analog and digital sections.
