PIC16LF1516T-I/SS Visão geral
What is a PIC microcontroller? A PIC (Peripheral Interface Controller) is a family of 8-bit/16-bit/32-bit microcontrollers built around a RISC architecture originally developed by General Instrument and now owned by Microchip Technology. PIC MCUs integrate a CPU core, Flash program memory, SRAM data memory, peripherals (ADC, timers, communication interfaces) and a power management block into a single IC. The PIC16F1xxx enhanced mid-range family sits in the middle of the PIC portfolio, balancing code density, peripheral integration, and ultra-low-power XLP operation for battery-powered and always-on applications.
The PIC16LF1516 includes a 10-bit ADC with up to 17 channels, two Capture/Compare/PWM (CCP) modules, one Enhanced CCP (ECCP), an MI2C (Master I2C) interface, an SPI interface, an EUSART, and an internal 16MHz oscillator. XLP technology enables extremely low active and sleep currents, making the LF variant (low-voltage F) suited for 2-cell battery or coin-cell designs. The "T" suffix denotes tape-and-reel delivery, and "-I" indicates the -40C to +85C industrial temperature range.
The enhanced mid-range core provides 49 instructions with 16 stack levels, supporting interrupt-driven designs and deterministic real-time response. Self-read/write Flash allows in-application firmware updates without an external programmer. Combined with peripheral pin select and configurable oscillator options, the PIC16LF1516 enables compact designs that minimize external components.
Typical applications include low-power sensor nodes, battery-powered IoT endpoints, industrial control logic, automotive body controllers, and home appliance user interfaces. Its small footprint and modest power budget also suit wearable health monitors and remote controls. For higher pin counts or larger memory, designers migrate within the same family to PIC16LF1517 (40-pin), PIC16LF1518 (44-pin) or PIC16LF1519 (44-pin).
When designing with this MCU, ensure the ICSP/ICD pins are routed to a debug header for MPLAB Snap/PICkit programming. Place a 100nF decoupling capacitor within 5mm of VDD, and follow Microchip's recommended oscillator layout for noise immunity.

Its 17-channel 10-bit ADC multiplexes temperature, humidity, light, and battery-voltage sensors without external analog switches. The 14KB Flash stores local buffering and OTA update routines; 512B RAM handles short message queues. Place it between a 3V coin cell and a low-power radio module, using MI2C/SPI to bridge sensors and the radio. Compared to PIC16F1455 it offers 3x more ADC channels and double the Flash, enabling multi-sensor fusion nodes that run for years on a single CR2032.
Recomendado
Industrial Control Logic / PLC Modules
The PIC16LF1516T-I/SS serves industrial 24V-bus logic controllers and PLC sub-modules where its -40C to +85C industrial range and 17 ADC inputs handle analog process variables. Two CCP and one ECCP modules drive PWM outputs for valve control, motor speed, or LED indicators while MI2C/SPI/EUSART connect to remote I/O expanders and HMI displays. The 14KB Flash fits deterministic ladder-logic replacement code, and 20MHz throughput handles 5 MIPS of scan-time work. Use an external LDO (e.g., MCP1700) to step 24V down to 3.3V for VDD. Compared to PIC16LF1517, the 28-pin SSOP saves PCB area in DIN-rail modules.
Recomendado
Home Appliance User Interface
The PIC16LF1516T-I/SS is well-suited for home appliance UI boards (washing machines, microwaves, dishwashers) because its 28 I/O pins directly drive 7-segment displays, keypad matrices, indicator LEDs, and buzzer control. Two CCP plus one ECCP handle PWM for backlight dimming and triac-fired heater regulation. The 14KB Flash stores menu logic and EEPROM emulation for user preferences, while 512B RAM holds runtime state. With MI2C it bridges to a capacitive touch controller and with EUSART to a main appliance MCU. The 28-SSOP slim body fits behind appliance panel cutouts.
Recomendado
Automotive Body Controllers (Non-Safety)
The PIC16LF1516T-I/SS fits non-safety automotive body controllers (window lift, mirror adjust, ambient lighting) where 1.8-3.6V supply aligns with vehicle 12V-buck derived rails and 28-SSOP withstands engine-bay thermal stress up to +85C. Its 17 ADC channels read position feedback from Hall sensors and potentiometers, while two CCP modules generate PWM for motor direction control. MI2C connects to seat-control master ECUs; SPI drives LED drivers for ambient lighting.

Notas de projeto
Place a 100 nF decoupling capacitor within 5 mm of the VDD pin (pin 20) and a bulk 10 uF tantalum or ceramic at the board power-entry point. The PIC16LF1516's nanoWatt XLP technology holds sleep current below 1 uA when peripherals are disabled - use Sleep mode aggressively between ADC samples to extend battery life in IoT applications. For 24V industrial rails, derive 3.3V via an MCP1700 LDO placed within 10 mm of VDD, with the input cap rated 25V minimum.
Route the ICSP pins RB6/ICSPCLK (pin 27) and RB7/ICSPDAT (pin 28) to a 6-pin header (with MCLR/VPP on pin 1) for MPLAB Snap/PICkit programming - never populate these pins with permanent loads that prevent in-circuit debugging. Place the 28-SSOP footprint on the top side with no traces under the body; keep a copper keepout zone around the crystal traces (RA6/OSC2 and RA7/OSC1) to minimize stray capacitance. Use a 4-layer stackup with a continuous ground plane under the MCU to reduce EMI.
Do not apply 5V signals to the PIC16LF1516 (LF variant) - maximum VDD is 3.6V. For 5V-tolerant designs, choose PIC16F1516T-I/SS (2.3-5.5V) instead. The MCLR/VPP/RE3 pin (pin 1) is the only 5V-tolerant input on the LF variant; do not float MCLR - tie it to VDD through a 10 kohm resistor. Avoid exceeding 20 MHz CPU clock at voltages below 2.7V (HF oscillator mode requires VDD >= 2.7V; below that use LF or MF modes at 4 MHz or less).
Estimated: The 28-SSOP package has theta_JA of approximately 95 C/W (per Microchip packaging thermal data). At maximum power consumption (CPU active at 20 MHz, all peripherals on, ADC sampling) typical VDD current is 4 mA - dissipation 14.4 mW at 3.6V produces a junction rise of 1.4C above ambient. Even at -40C ambient the part operates 100C below the +150C absolute maximum. No heatsink or thermal copper pour is required.
