PIC16F1516-I/MV - 14KB Flash 8-bit MCU, 28-UQFN | Microchip
MPN: PIC16F1516-I/MV ✓ Hoạt độngPIC16F1516-I/MV Tóm tắt
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, working RAM, and a rich peripheral set around a compact Harvard or von-Neumann core. PIC microcontrollers implement a Harvard RISC architecture and sit within the larger taxonomy: microcontroller -> embedded controller -> semiconductor IC. They are widely used where deterministic timing, low power, and small footprint matter more than raw compute throughput - exactly the niche the PIC16F1516 targets with nanoWatt XLP technology.
Key features include a 49-instruction enhanced mid-range core with 16-level stack, two Capture/Compare/PWM (CCP) modules, one enhanced 16-bit timer (TMR1), two 8-bit timers (TMR0/TMR2), an extended watchdog timer (WDT), I2C/SPI/EUSART with auto-baud, programmable ultra-low-power brown-out reset (ULPBOR), in-circuit serial programming (ICSP), and in-circuit debug. The device supports 25 mA source/sink on I/O lines, enabling direct LED drive in many applications.
Architecturally, the PIC16F1516 combines a wide-voltage CMOS process with sleep currents below 1 µA typical, making it well-suited to battery-powered and energy-harvesting designs. The 17-channel 10-bit ADC plus on-chip voltage reference eliminates external analog components in many sensor interfaces, while the dual CCP and 16-bit timer support motor control, fan control, and SMPS sequencing.
Typical applications include IoT sensor nodes, home automation controllers, low-power wireless sensor platforms (when paired with a sub-GHz or BLE transceiver), battery-powered medical monitors, industrial fan and pump control, LED lighting controllers, and consumer appliances. The 4x4 mm UQFN package allows the part to fit into space-constrained designs that need more peripherals than 8-bit GPIO-limited MCUs.
Design tip: when migrating from a SOIC-28 footprint, verify the UQFN-28 land pattern and use a PCB with ENIG finish for reliable manufacturing. Decouple VDD with a 100 nF X7R ceramic placed within 3 mm of the pin, and route the MCLR pin with a 10 kΩ pull-up. The internal 16 MHz oscillator is factory-trimmed and typically needs no external crystal for cost-sensitive designs.

Ứng dụng tiêu biểu
PIC16F1516-I/MV phù hợp cho 6 Áp dụngs: IoT Sensor Node Controller, Home Automation Controller, Battery-Powered Medical Monitor, Industrial Fan and Pump Controller, LED Lighting Controller, Consumer Appliance Control Board.
IoT Sensor Node Controller
The PIC16F1516-I/MV is well-suited as the host MCU for low-power IoT sensor nodes that periodically wake, read sensors, transmit data, and return to deep sleep. Its nanoWatt XLP technology delivers sub-1 µA typical sleep current at 2.5 V, while the 14 KB flash accommodates over-the-air firmware update staging. The 17-channel 10-bit ADC with internal voltage reference allows direct interface to multiple analog sensors (temperature, humidity, light, battery voltage) without external components. The 28-UQFN 4x4 mm package fits in coin-cell powered designs. Pair with a sub-GHz or LoRa transceiver for long-range battery telemetry.

Home Automation Controller
In wall-switches, dimmers, and smart-plug designs, the PIC16F1516-I/MV provides the deterministic timing and I/O drive capability needed for reliable AC-line-coupled control. Its 25 mA source/sink I/O directly drives TRIACs, optocouplers, and relay coils, while the dual CCP modules generate zero-cross synchronized PWM for phase-angle dimming. The 17-channel ADC reads current, voltage, and temperature sensors for energy monitoring. I2C / SPI / EUSART with auto-baud connects to Wi-Fi or BLE modules. EUSART auto-baud eliminates crystal calibration on production lines.

Industrial Fan and Pump Controller
The PIC16F1516-I/MV handles single-phase BLDC and brushed DC motor control for industrial fans, water pumps, and HVAC blowers. Its 16-bit TMR1 captures tachometer feedback from Hall sensors, while the dual CCP modules generate complementary PWM with dead-band insertion. The 17-channel ADC monitors motor current (via shunt), supply voltage, and temperature. Programmable ULPBOR survives brown-outs common in industrial AC-line environments. The E temperature-grade variant (PIC16F1516-E/MV) extends operation to +125C junction for sealed-motor applications.

LED Lighting Controller
Architectural and stage LED lighting benefit from the PIC16F1516-I/MV's 25 mA I/O drive (directly switching low-current LED strings), dual CCP PWM channels for color mixing, and EUSART for DMX-512 or proprietary LED-protocol reception. The 17-channel ADC monitors LED forward voltage and ambient light for closed-loop brightness control. The 14 KB flash supports animation sequences and user presets, while nanoWatt XLP sleep extends battery life in portable fixtures. UQFN-28 4x4 mm fits inside LED-driver PCB cutouts without increasing fixture depth.

Consumer Appliance Control Board
Coffee machines, washing machines, and small kitchen appliances use the PIC16F1516-I/MV for front-panel control, sensor fusion, and motor sequencing. The I2C/SPI peripherals connect to capacitive touch ICs and EEPROM; the 10-bit ADC reads thermistors for closed-loop temperature control; the dual CCP drives solenoid valves and pump relays via 25 mA I/O. The 14 KB flash holds UI graphics for segment-LCD panels via the EUSART, while the 512 B RAM manages key-press debounce and timer state. Wide 2.5 V-5.5 V supply tolerates unregulated rectified mains.

Ghi chú thiết kế
Estimated: at 20 MHz active, VDD=5 V, the PIC16F1516-I/MV draws approximately 4 mA active and <1 µA sleep typical (per PIC16F15xx family datasheet trends). For battery-powered designs, use the SLEEP/IDLE modes aggressively; wake via WDT, ADC conversion-complete interrupt, or external INT on RB0. Place a 100 nF X7R decoupling capacitor within 3 mm of the VDD pin, and a 10 µF bulk cap if the supply rail is shared with a radio module.
The 28-UQFN (4x4 mm) package has a center thermal/exposed pad that must be soldered to a PCB land of at least equal size to meet thermal and mechanical reliability goals. Use NSMD pads with ENIG or OSP finish. The UQFN-28 (4x4) variant ('MV') and UQFN-28 (6x6) variant ('ML') have different PCB footprints - verify the land pattern against the package code before PCB fabrication.
Do not exceed 5.5 V on VDD - the LF variant (1.8 V-3.6 V) is permanently damaged above 4.0 V. Verify the silicon variant before powering up. Leave RA3 configured as MCLR with a 10 kΩ pull-up to VDD; if RA3 is used as GPIO, configure it in CONFIG words. Code-protect unused flash regions if the firmware contains proprietary algorithms.
