PIC16F1517-I/MV - 8-Bit 20MHz MCU, 14KB Flash, 40-UQFN | Microchip
MPN: PIC16F1517-I/MV ✓ نشطPIC16F1517-I/MV نظرة عامة
A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory (Flash), volatile data memory (RAM), and peripherals such as timers, ADC, communication interfaces, and I/O. Within the broader taxonomy, the PIC16F1517 sits in the PIC16 enhanced mid-range family -> 8-bit microcontroller -> MCU -> embedded processor -> semiconductor. Microcontrollers are the standard building block of embedded systems in consumer, industrial, automotive, and IoT products, executing deterministic firmware to control sensors, actuators, and user interfaces.
Key features include 14KB self-programmable Flash with code protection, 512B data SRAM, two 8-bit timers (TMR0/TMR2), one 16-bit timer (TMR1), an extended Watchdog Timer (WDT), enhanced Power-On Reset (POR) and programmable ultra-low-power Brown-Out Reset (ULPBOR), In-Circuit Serial Programming (ICSP), on-board in-circuit debug, 25 mA source/sink I/O, and a voltage reference for the ADC. PIC16F1517 (2.3 V to 5.5 V) and PIC16LF1517 (1.8 V to 3.6 V) variants share the same die, providing a single firmware image across industrial and low-voltage portable rails.
The architecture is an 8-bit Harvard RISC core with a 14-bit instruction word, multiple oscillator options (HFINTOSC, LFINTOSC, external crystal/clock), and configurable clock switching for low-power modes. The 28-channel 10-bit ADC combined with internal voltage reference supports sensor-array sampling in industrial control loops. The peripheral set is intentionally lean - no USB, no CAN, no I2C/SPI hardware named in the family overview - keeping the cost-per-MIPS competitive for high-volume sensor and lighting products.
Typical applications include industrial sensor conditioning and control, low-power IoT edge nodes, LED lighting controllers, battery chargers with ADC monitoring, and home appliances. The wide 2.3 V to 5.5 V operating range supports direct connection to 4 NiMH, single Li-ion, or 5 V regulated rails.
When designing with this device, ensure the WDT is correctly configured for your reset window, place the decoupling capacitor as close to VDD/AVDD as possible, and verify the I/O source/sink budget (25 mA per pin) against your LED or relay driver stage. The ICSP/ICD pins share I/O functions - allocate them carefully if in-circuit debug is required in production.

التطبيقات النموذجية
PIC16F1517-I/MV مناسب لـ 7 التطبيقs: Industrial Sensor Conditioning, Low-Power IoT Edge Node, LED Lighting Controller, Battery Charger with ADC Monitoring, Home Appliance Control Board, Automotive Interior Lighting / Switch Panel, Motor Speed Control (Small BLDC / Fan).
Industrial Sensor Conditioning
The PIC16F1517-I/MV suits multi-channel industrial sensor conditioning because of its 10-bit ADC with up to 28 channels, 2.3 V-5.5 V supply range, and 25 mA I/O source/sink per pin. Each ADC channel can sample a bridge sensor, thermistor, or 4-20 mA loop interface in a PLC remote I/O module. The enhanced mid-range 14-bit core at 20 MHz executes 200 ns instructions, providing deterministic loop times for control firmware. PIC16F1517 replaces multiple discrete op-amp signal chains with one MCU plus internal voltage reference.

Low-Power IoT Edge Node
The PIC16F1517-I/MV fits low-power IoT edge nodes thanks to nanoWatt XLP technology, sleep currents in the microamp range, and LFINTOSC for ultra-low-power timing. It runs from 2 NiMH cells, a single Li-ion, or a regulated 3.3 V rail, and wakes from sleep on interrupt to read a sensor and transmit via UART. The 14 KB Flash holds a small TCP/IP or LoRaWAN stack shim plus application logic. This integration removes the need for an external RTC or supervisor IC in many battery-powered deployments.
موصى به
LED Lighting Controller
The PIC16F1517-I/MV is appropriate for LED lighting controllers because of its 25 mA per-pin source/sink capability, which can directly drive small LED strings or MOSFET gates for higher-power luminaires. The 10-bit ADC and internal voltage reference close the loop on ambient light sensors and current-sense shunts for constant-current regulation. The 20 MHz core drives PWM dimming at audio-bead-free frequencies while leaving cycles for housekeeping. This combination suits architectural, horticultural, and automotive interior lighting.
موصى به
Battery Charger with ADC Monitoring
The PIC16F1517-I/MV serves as the control brain of a battery charger where the 10-bit ADC monitors charge current, battery voltage, and temperature with up to 28 channels for cell balancing in multi-cell packs. The 2.3 V-5.5 V operation directly powers from a 4 NiMH or single Li-ion stack, while HFINTOSC keeps timing accurate for CC/CV charge profiles. Enhanced POR and programmable ULPBOR protect against brown-out during load transients. The wide temperature range supports outdoor or under-hood charger designs.
موصى به
Home Appliance Control Board
The PIC16F1517-I/MV powers home appliance control boards such as washing machines, dishwashers, and HVAC dampers where cost-sensitive 8-bit performance is sufficient. Its 14 KB Flash holds the full state machine for user-interface buttons, motor timing, and fault diagnostics. The extended Watchdog Timer (WDT) provides class-B safety integrity for unattended appliances, while ICSP and on-board in-circuit debug shorten development cycles. The 40-pin UQFN package keeps the PCB compact for tight enclosures.
موصى به
Automotive Interior Lighting / Switch Panel
The PIC16F1517-I/MV supports automotive interior lighting and switch-panel modules where 8-bit deterministic control with PWM dimming and ADC monitoring is required. The -I industrial temperature grade covers interior cabin environments; for under-hood or AEC-Q100 needs, the PIC16F1517 family is generally not automotive-qualified and designers should evaluate the PIC16F15275 or PIC16F1xx automotive families instead. The 25 mA I/O directly drives RGB LED indicators and relay coils.
موصى به
Motor Speed Control (Small BLDC / Fan)
The PIC16F1517-I/MV drives small brushless DC fans and pumps by generating complementary PWM with dead-time control on the 8-bit/16-bit timers, while the 10-bit ADC samples back-EMF or shunt current for closed-loop regulation. The 20 MHz instruction rate sustains commutation loops above 50 kHz without CPU stalls. The industrial temperature range and 5.5 V absolute maximum tolerate noisy motor power environments, and the small UQFN footprint suits compact fan PCBs.

ملاحظات التصميم
Place a 100 nF decoupling capacitor as close as possible to each VDD pin (pins 10 and 28 on the 40-pin UQFN) and a single 10 uF bulk capacitor on the supply rail. The PIC16F1517 nanoWatt XLP modes drop quiescent current to microamp levels, but a noisy VDD ripple above 50 mVpp can wake the BOR or cause ADC reference error. Estimated: at 20 MHz CPU clock from a 3.3 V supply, active current is roughly 2-4 mA, so a 10 uF bulk cap sustains voltage during ADC bursts without significant droop.
The 40-pin UQFN (5x5 mm) requires an exposed pad for thermal dissipation and ground reference; stitch vias on a 0.5 mm pitch grid beneath the e-pad to a ground pour on the opposite PCB layer. Do not route signal traces under the package body unless they are on inner layers and isolated by ground planes. Estimate: copper area of at least 25 mm^2 keeps junction temperature rise under 20 C above ambient at the rated 25 mA per-pin load.
PIC16F1517 I/O source/sink is rated 25 mA per pin, but the absolute maximum per PORT is 75 mA and per PACKAGE is 200 mA - exceeding the per-port total when driving multiple LEDs simultaneously causes voltage droop and latch-up risk. Configure the extended WDT before relying on it for class-B safety, since the default postscaler may be too aggressive. The ICSP pins (RB6/RB7) share GPIO functions; if you bind them to user buttons, in-circuit debug will fail in production.
Keep analog traces (AN0-AN27) short and away from the PWM outputs on RC0-RC7 to minimize ADC crosstalk. Place the internal voltage reference decoupling capacitor (typically 1 nF) as close as possible to the VREF pin if used externally. Route the HFINTOSC crystal traces symmetrically with a ground guard ring if stability below 1% is required; otherwise use the internal oscillator and accept its 1-2% tolerance across temperature.
