PIC16C715T-20E/SS 概要
A PIC (Peripheral Interface Controller) microcontroller is a compact RISC-based computer-on-a-chip that integrates a CPU core, non-volatile program memory, working RAM, and peripheral blocks such as timers, comparators and analog-to-digital converters. The PIC16C71X family belongs to Microchip's PIC16 mid-range architecture, positioned between the baseline PIC10/12/16 families and the high-performance PIC18/dsPIC lines, and is widely used in cost-sensitive embedded designs that need an integrated ADC.
Key features of the PIC16C715 include 4 channels of 8-bit ADC, an integrated 8-bit timer/counter with 8-bit prescaler, a Watchdog Timer with its own on-chip RC oscillator, an 8-level deep hardware stack, and a programmable code protection mechanism. The device operates across 2.5 V to 6.0 V (typical 5 V) with industrial temperature range support, and the "E" suffix designates the extended temperature grade.
Architecturally, the PIC16C715 uses a Harvard-style RISC core with separate program and data buses, allowing instruction fetch and operand access to occur in the same cycle. Its OTP EPROM program memory is one-time programmable using a standard EPROM programmer, which historically made this part popular for low-to-medium volume production runs before Flash-based PIC16F equivalents became dominant. Microchip now recommends the pin-compatible PIC16F716 as the modern flash-reprogrammable replacement.
Typical applications include motor control front-ends, automotive sensor interfaces, white goods and appliance control, low-cost remote sensors, and battery-powered instrument front panels that benefit from integrated ADC. Its small 20-pin SSOP footprint also suits consumer products where PCB area is at a premium.
Designers should note that OTP parts cannot be re-programmed in-circuit; production firmware must therefore be fully validated before programming. The "-20E" suffix indicates 20 MHz maximum clock with extended operating temperature range, while the SSOP package offers a more compact alternative to the PDIP for space-constrained layouts.

主な用途
PIC16C715T-20E/SS の用途: 6 件s: Industrial Sensor Interface, Automotive Body Control Module, White Goods Appliance Control, Low-Cost Battery-Powered Instrument, Remote Control and HMI Front-End, Small Motor Driver Front-End.
Industrial Sensor Interface
The PIC16C715T-20E/SS fits industrial 4-20 mA sensor interfaces because its integrated 4-channel 8-bit ADC and 20 MHz core provide sufficient resolution and throughput for thermocouple, RTD bridge, and potentiometer position readouts, while the -40C to +125C extended temperature grade handles factory-floor thermal stress. Placed on the sensor PCB with the analog inputs tied to AN0-AN3 through RC anti-alias filters, the chip runs the ADC sequentially and reports scaled values over UART or I/O. Designers should add TVS protection on each analog input and reference the internal 5V reference for ratiometric measurements.
おすすめ
Automotive Body Control Module
The PIC16C715T-20E/SS is well-suited to automotive body-electronics sub-modules (window lift, mirror adjust, seat controller) because its 20 MHz mid-range core executes switch-debounce and PWM logic with low latency, and the extended temperature grade survives under-hood thermal cycling. Used as a slave controller behind a CAN/LIN master, the PIC16C715 reads switch states through its digital I/O and drives relays via discrete MOSFETs. For new automotive programs, migrate to AEC-Q100-qualified PIC16F variants; the legacy C-part is retained only for service and aftermarket production.
おすすめ
White Goods Appliance Control
In white goods such as washing machines, dishwashers and microwave ovens, the PIC16C715T-20E/SS controls front-panel keypads, drives 7-segment or LCD displays, and reads analog water-level or temperature sensors through its 4-channel 8-bit ADC. The 35-instruction RISC core is simple enough for legacy 8-bit firmware, while the integrated watchdog timer with its own RC oscillator improves robustness against brown-outs in motor-driven appliances. Place the IC near the user-interface board with proper isolation from mains-side switching noise.
おすすめ
Low-Cost Battery-Powered Instrument
The PIC16C715T-20E/SS operates from 2.5 V to 6.0 V, allowing direct connection to 3 V lithium or multi-cell alkaline battery packs without additional regulation, while its low-power CMOS implementation extends operating life in portable measurement tools. Typical uses include handheld multimeters, infrared thermometers, and environmental loggers that sample analog sensors periodically and store results. To minimize current draw, put the MCU in SLEEP mode between ADC conversions and wake it via the watchdog timer interrupt.
おすすめ
Remote Control and HMI Front-End
Consumer remote controls, thermostat keypads and small HMI panels benefit from the PIC16C715T-20E/SS combination of integrated ADC (for temperature or light sensing), 20 MHz core (for button-matrix scanning and IR encoding), and compact SSOP-20 footprint. Place the device as the master controller of a 4x4 key matrix and PWM-controlled LED or buzzer feedback, with the ADC monitoring ambient light to auto-dim the display. The small SSOP package also keeps the BOM small for cost-sensitive consumer SKUs.
おすすめ
Small Motor Driver Front-End
The PIC16C715T-20E/SS acts as the digital front-end for low-power DC motor or stepper drivers in appliances, fans, and small pumps. It generates PWM signals for the power stage, reads back current/voltage feedback through the ADC, and implements closed-loop control algorithms in firmware. The 20 MHz core easily handles the control loop at typical PWM frequencies of a few kHz, and the integrated watchdog protects against firmware lockup in safety-relevant applications. Use optocouplers between the MCU and the high-voltage power stage for isolation.

設計ノート
Add a 100 nF ceramic decoupling capacitor as close as possible to the VDD pin (pin 14) and a bulk capacitor (e.g., 10 uF tantalum or aluminum) at the board supply input. For battery-powered designs running below 4.5 V, the MCU can operate at reduced clock frequency; derate the 20 MHz spec linearly - at 2.5 V the maximum frequency is approximately 4 MHz. Estimate: each MHz of CPU clock draws roughly 1-2 mA of supply current at 5 V.
The SSOP-20 footprint has 0.65 mm pin pitch - use a fine-pitch PCB process and consider solder mask defined (SMD) pads rather than non-solder mask defined (NSMD) for easier inspection. Place the crystal or resonator within 5 mm of OSC1/OSC2 (pins 16/15) and keep the traces short and symmetric to minimize clock distortion. Add a ground ring around the crystal and tie it to VSS to reduce radiated EMI from the oscillator.
OTP memory can be programmed only once - any firmware bug locked into the PIC16C715 cannot be field-updated. Validate the entire firmware on a PIC16F716 (Flash) development board before committing code to OTP production units. Also note that the MCLR/VPP pin (pin 4) must NOT be left floating; tie it to VDD through a 10 kohm resistor or drive it directly from the supervisor, otherwise spurious resets will occur in noisy environments.
When using the on-chip ADC for analog measurements, route the analog signals (AN0-AN3, pins 17-18 and 1-2) away from digital switching traces such as the oscillator and PWM outputs. Place a small RC filter (typically 1 kohm + 100 pF) on each analog input to limit noise bandwidth. Use AVSS = VSS and ensure VDD is well decoupled - the PIC16C715 has only one supply pin and shares it for digital and analog circuitry, so a clean VDD rail is essential for ADC accuracy.
