PIC16LC715T-04/SS 概要
Background - What is an 8-bit microcontroller with A/D? An 8-bit MCU is a single-chip computer that processes data in 8-bit-wide chunks and is the workhorse of embedded control. The PIC16C71X family, of which the PIC16LC715 is a member, sits in Microchip's mid-range PIC architecture hierarchy: PIC10/12/16 base architecture -> PIC16C71X with ADC -> PIC16LC715 low-power CMOS variant. The integrated ADC removes the need for an external converter, lowering BOM cost and PCB area in sensor-interface designs.
Key features include 13 digital I/O lines, three timer modules (8-bit Timer0 with 8-bit prescaler, 16-bit Timer1 with external crystal/clock capability during sleep, and 8-bit Timer2), a 4-channel 8-bit A/D converter, an on-chip RC oscillator, and a watchdog timer for safe operation. The OTP memory is one-time programmable - once written the program is permanent and cannot be erased or rewritten.
Architecturally the PIC16LC715 uses a Harvard RISC core with separate program and data buses, a 14-bit instruction word, and a 35-instruction set. The CMOS low-power ("LC") process reduces quiescent current compared to the standard NMOS PIC16C715, making it well suited to battery-powered or thermally constrained embedded designs. The integrated brown-out reset and power-on reset circuits further reduce external component count.
Typical applications include battery-powered sensor signal conditioning, low-speed industrial control, smart instrumentation with analog front ends, simple closed-loop PWM motor control, and white-goods / appliance control boards where the ADC and timers replace discrete analog hardware. The wide 2.5-5.5 V supply range also supports direct connection to 3-cell battery packs and regulated 5 V rails.
Design consideration - the OTP memory cannot be re-programmed in-circuit. If firmware revisions are anticipated, choose the PIC16F716 (Flash-based) or PIC16CR715 (ROM-based) equivalent. For pin-compatible modern replacements, consider the PIC16F716 family in SOIC/SSOP packages.

主な用途
PIC16LC715T-04/SS の用途: 6 件s: Battery-Powered Sensor Signal Conditioning, Low-Speed Industrial Control, Smart Instrumentation with Analog Front End, Appliance and White-Goods Control, PWM Motor Speed Control, Educational and Hobby Embedded Projects.
Battery-Powered Sensor Signal Conditioning
The PIC16LC715T-04/SS fits battery-powered sensor front-end designs because its low-power CMOS process and wide 2.5-5.5 V supply range allow direct connection to 3-cell battery packs without a regulator. The integrated 4-channel 8-bit ADC samples analog sensor signals (temperature, light, pressure) and converts them to digital values without an external converter, while the 128-byte RAM is sufficient for data smoothing. Placed on a sensor daughter board with three AAA cells, it offers years of standby life because the LC process draws microamp-level quiescent current during sleep between ADC conversions.
おすすめ
Low-Speed Industrial Control
The PIC16LC715T-04/SS is well suited to low-speed industrial control loops because its 4 MHz clock and 1 MIPS performance comfortably handle PID-style control at sub-kHz loop rates. The three timers (8-bit Timer0, 16-bit Timer1, 8-bit Timer2) enable PWM generation for motor or valve actuation, while the 13 digital I/Os interface with opto-isolated inputs and relay drivers. Its integrated ADC reads 4-20 mA loop signals through a shunt resistor, eliminating an external converter IC and reducing BOM cost by approximately $0.50 per board in panel-meter and process-controller applications.
おすすめ
Smart Instrumentation with Analog Front End
For smart instruments the PIC16LC715T-04/SS replaces discrete logic with a single-chip analog+digital solution: its 8-bit ADC digitizes sensor inputs, the 13 I/O lines drive displays and keypads, and the OTP memory stores calibrated lookup tables. The 35-instruction PIC mid-range set is simple enough for assembly or C code generation by hobbyists and engineers alike. At 4 MHz it executes 1 MIPS - sufficient for menu-driven user interfaces and modest signal-processing algorithms such as moving-average filtering of ADC samples.
おすすめ
Appliance and White-Goods Control
The PIC16LC715T-04/SS is an established choice for appliance control boards (washing machines, dishwashers, microwave ovens) where cost dominates design decisions and one-time programmable memory is acceptable. Its 13 I/Os drive seven-segment displays, triac-based motor controls, and keypad matrices, while the integrated ADC reads thermistor temperature sensors for safety cutoffs. The 2.5-5.5 V supply range is compatible with rectified 5 V rails from offline switching supplies, and the SSOP-20 footprint enables compact PCB layouts inside small appliance chassis.
おすすめ
PWM Motor Speed Control
The PIC16LC715T-04/SS generates PWM outputs for brushed DC motor speed control via its 8-bit Timer2 module. With 4 MHz clock and 1 MIPS performance, PWM frequencies up to 20 kHz (above audible range) are achievable while leaving instruction bandwidth for closed-loop control algorithms. The integrated ADC samples motor current or back-EMF for speed regulation, and the 13 digital I/Os drive direction-control H-bridges and tachometer inputs. At $2-3 per unit in production reels it is a cost-effective choice for small fans, pumps, and hobby servo controllers.
おすすめ
Educational and Hobby Embedded Projects
The PIC16LC715T-04/SS is a popular platform for educational and hobby embedded projects because the PIC16C71X family has decades of tutorial material, free C compilers (XC8), and inexpensive programmers (PICkit 3/5). Students learn 8-bit RISC concepts, A/D conversion, and timer-based PWM on a part that is simple enough to fully understand yet capable of real applications. The SSOP-20 package fits standard breakout PCBs and breadboard adapters, and the 2.5-5.5 V supply is safe for battery-powered student projects. OTP memory encourages disciplined firmware development because each program cycle consumes a part.

設計ノート
The PIC16LC715T-04/SS OTP memory cannot be re-programmed - once programmed, the firmware is permanent. For prototypes and design iteration choose the Flash-based PIC16F716-I/SS instead (same SSOP-20 footprint, same PIC16C71X architecture). When commissioning OTP production parts, always verify firmware on a Flash equivalent first; a single OTP-programming error destroys the part.
The PIC16LC715T-04/SS operates from 2.5 V to 5.5 V but the brown-out reset (BOR) trip point is internally set and may not match your battery end-of-life voltage. For 3-cell alkaline designs (3.6-4.8 V), add an external voltage supervisor (e.g., MCP100) to guarantee a clean reset when batteries drop below 2.7 V. The on-chip RC oscillator reduces component count but is less accurate than a crystal - calibrate the ADC reference against VDD for absolute measurements.
Place the 0.1 VDD decoupling capacitor within 5 mm of the VDD pin (pin 15) and the ground connection within 5 mm of the VSS pin (pin 5 or 14). The ADC inputs RA0-RA3 are high-impedance and sensitive to noise - route analog traces away from the OSC1/OSC2 clock traces and digital I/O switching lines. Add a 100 nF ceramic between VREF (pin 3) and ground for ADC reference stability when using external voltage references.
The ICSP programming pins RB6/PGC (pin 12) and RB7/PGD (pin 13) are also general-purpose digital I/Os. If your application uses these pins for external circuitry (LEDs, relays), add 4.7 kOhm series resistors to allow in-circuit programming without removing the load. The MCLR pin (pin 18) requires a 10 kOhm pull-up to VDD for normal operation; do not leave it floating or the MCU will randomly reset from noise.
