PIC16LF1615T-I/ML - 14KB Flash 8-Bit MCU, 32MHz, 16-QFN | Microchip
MPN: PIC16LF1615T-I/ML ✓ Hoạt độngPIC16LF1615T-I/ML Tóm tắt
An 8-bit microcontroller (MCU) is a small, low-power computing device integrating a CPU, program memory (Flash/ROM), data memory (RAM), peripherals (ADC, timers, communication interfaces), and clock generation on a single silicon die. MCUs belong to the broader category of embedded microcontrollers, sitting below microprocessors (MPUs) in system-on-chip hierarchy and powering applications where deterministic, low-power, real-time control is required. The PIC® XLP™ (eXtreme Low Power) family extends this hierarchy by targeting battery-operated and energy-harvesting designs.
Key features include the XLP™ ultra-low-power technology enabling sub-µA sleep currents, hardware math accelerator (MathACL) for 16-bit arithmetic without CPU overhead, Configurable Logic Cell (CLC) for custom combinational/sequential logic, and integrated peripherals such as zero-cross detect (ZCD) and complementary waveform generator (CWG). The 32 MHz core delivers 8 MIPS of throughput, while C compiler-friendly Harvard architecture and the MPLAB® X IDE + MPLAB® Code Configurator (MCC) toolchain simplify firmware development.
The architecture is based on the enhanced mid-range PIC® core with a 14-bit instruction word and hardware stack. Program execution is deterministic with a fixed instruction cycle, supporting low-latency interrupt response needed in real-time control loops. The device integrates 1024 bytes of EEPROM for non-volatile data storage, supporting endurance typically above 100k cycles.
Typical applications include small appliance control, LED lighting ballasts, fan and pump control, sensor signal conditioning nodes, and low-power IoT sensor edge nodes. Its combination of 14 KB Flash and a rich analog/digital peripheral set makes it a fit for designs consolidating discrete logic into one MCU.
When designing with the PIC16LF1615T-I/ML, ensure input supply decoupling (≥100 nF + ≥1 µF bulk) is placed within 5 mm of the VDD pin. The exposed thermal pad (EP) of the QFN package must be soldered to a continuous ground plane to meet thermal and electrical performance.

Ứng dụng tiêu biểu
PIC16LF1615T-I/ML phù hợp cho 6 Áp dụngs: Small Appliance Control, LED Lighting Ballast / Driver Control, Fan / Pump Motor Control, Sensor Edge Node / IoT Terminal, Battery Charger Supervisory MCU, Industrial Sensor Signal Conditioning.
Small Appliance Control
The PIC16LF1615T-I/ML fits small appliance control boards due to its 32 MHz core providing 8 MIPS, 14 KB Flash, and XLP™ sub-µA sleep current. For a coffee maker or kettle controller, it reads temperature via the 10-bit ADC, drives a triac/relay via PWM, and supervises safety timers. Compared to a discrete logic-only design, consolidating logic into this MCU saves PCB area. The 1.8 V-3.6 V VDD range is ideal for direct Li-ion or 2×AA battery operation. Its 12 I/O pins are sufficient for keypad input, LED indicators, and the main load.

LED Lighting Ballast / Driver Control
The PIC16LF1615T-I/ML suits LED lighting ballasts through its integrated CWG (Complementary Waveform Generator), 10-bit ADC, and ZCD (Zero-Cross Detect) peripherals, which together implement dimmable constant-current LED drivers without external PWM ICs. With 14 KB Flash and 32 MHz core, it can run a DALI or 0-10 V dimming protocol stack and a thermal-folding algorithm. The XLP™ sleep mode drops to sub-µA when standby, critical for emergency-lighting battery backup. Compared to a dedicated LED driver IC, this approach adds programmability but requires firmware.

Fan / Pump Motor Control
The PIC16LF1615T-I/ML handles single-phase brushless DC fan or small pump control with its 32 MHz core (8 MIPS), hardware 16-bit MathACL for closed-loop RPM math, and PWM + CWG peripherals for synchronous rectification. With 14 KB Flash it can store PID loop coefficients, fault logs, and a small protocol stack (I²C/UART) for external supervision. The XLP™ sleep current is critical for battery-backed pump alarms. Its 1.8 V-3.6 V range directly supports 2×AA or Li-ion battery inputs. Use the Configurable Logic Cell to debounce Hall-sensor inputs in firmware-free logic.

Sensor Edge Node / IoT Terminal
The PIC16LF1615T-I/ML is a strong fit for battery-powered IoT sensor edge nodes thanks to its XLP™ sub-µA sleep current, 32 MHz active processing, and 14 KB Flash. For a temperature/humidity sensor node reporting every 60 s via a sub-GHz or LoRaWAN module, the MCU spends most of its time in sleep and wakes the radio only on transmission. Its 1.8 V-3.6 V VDD directly supports coin-cell or Li-ion batteries. The 10-bit ADC handles sensor digitization at 0.5 °C resolution. The CLC peripheral can implement glue logic for the radio without external gates.

Battery Charger Supervisory MCU
The PIC16LF1615T-I/ML fits handheld battery charger supervisory roles with its 10-bit ADC for V/I monitoring and 14 KB Flash for CC/CV algorithm state machines. With 32 MHz core, it can sample at 1 kHz and run PID-style charge regulation. The 1.8 V-3.6 V VDD range is ideal for single-cell Li-ion chargers with NTC thermistor safety monitoring. The CLC peripheral can implement protection logic (over-voltage, over-temperature) in parallel with firmware, ensuring fail-safe behavior. Its 1024-byte EEPROM stores charge-profile parameters and tamper counters.
Được đề xuất
Industrial Sensor Signal Conditioning
The PIC16LF1615T-I/ML supports industrial sensor signal conditioning nodes: thermocouple/RTD linearization, 4-20 mA loop transmitter emulation, or strain-gauge bridge excitation. With its 10-bit ADC, 14 KB Flash for lookup tables, and 32 MHz core for floating-point math emulation, it can convert raw ADC readings into calibrated engineering units (°C, psi, N). The hardware CLC peripheral can debounce noisy digital inputs without firmware polling. The industrial -40 °C to +85 °C temperature range ensures reliable operation in factory-floor enclosures. UART/SPI enables communication with downstream PLCs.

Ghi chú thiết kế
Place the decoupling capacitor (≥100 nF X7R ceramic in 0402 or 0603) within 5 mm of the VDD pin (pin 14) and a ≥1 µF bulk cap on the same rail. The exposed thermal pad (EP) of the 16-QFN package MUST be soldered to a continuous ground plane with thermal vias for heat spreading; otherwise thermal resistance rises and RF emissions may increase. Keep analog signal traces short and isolated from switching signals to maintain 10-bit ADC accuracy.
For XLP™ sleep-current design, set all unused I/O pins to outputs driven low and disable unused peripherals via the PMD (Peripheral Module Disable) registers. Use Sleep mode with WDT disabled to reach sub-µA. Wake sources are INT pin, WDT timeout, or peripheral interrupt. For 32 MHz active operation, ensure VDD stays above 1.8 V (per datasheet electrical characteristics); brown-out at 1.8 V may corrupt Flash. Enable BOR via configuration bits for reliable boot-up.
Route the ICSP pins (ICSPDAT = RA0, ICSPCLK = RA1) to an in-circuit programming header or test pad so that firmware can be updated after PCB assembly. The MCLR pin (RA3 alternate) must have a 10 kΩ pull-up to VDD for normal operation and a diode clamp to VDD for in-circuit programming isolation. Use a 4-layer stack-up with a dedicated ground plane to minimize EMI; ground pours on the top layer also help the EP function as a thermal path.
Common pitfalls with the PIC16LF1615T-I/ML: (1) Do not exceed 3.6 V on VDD - the LF variant is a low-voltage part and latch-up occurs above the absolute maximum; choose the F variant if 5 V is required. (2) Ensure the configuration bits select the correct oscillator source - default is INTOSC at 32 MHz, but for low-power applications the 31 kHz LFINTOSC may be preferred. (3) When migrating from PIC16F1615 to PIC16LF1615, check that any 5 V-rail peripherals have a level shifter; the LF I/O is 3.3 V CMOS.
