PIC16LF1615-I/ST - 8-bit MCU, 32MHz, 14KB Flash 14-TSSOP | Microchip
MPN: PIC16LF1615-I/ST ✓ Hoạt độngPIC16LF1615-I/ST Tóm tắt
A PIC (Peripheral Interface Controller) microcontroller is an 8-bit RISC-based microprocessor with integrated Flash program memory, RAM, EEPROM, and a rich set of on-chip peripherals. Within the broader taxonomy, the PIC16LF1615 sits as: PIC16F1615 -> 8-bit PIC microcontroller -> PIC microcontroller -> microcontroller -> embedded processor -> semiconductor. The 'LF' prefix indicates the low-voltage / low-power variant, supporting operation down to 1.8V and featuring Microchip's XLP™ (eXtreme Low Power) sleep modes that draw nanoamp-level currents in deep sleep.
Key features include 14KB of self-programmable Flash program memory, 1KB of RAM, hardware peripherals such as 10-bit A/D converter, Capture/Compare/PWM (CCP), 24-bit Signal Measurement Timer (SMT), Zero-Cross Detection, and a complementary waveform generator for motor control. The 'LF' variant supports 1.8V-3.6V operation, making it suited for battery-powered applications. Programming is supported via In-Circuit Serial Programming (ICSP) and high-voltage ICSP, with the industrial temperature grade (-40C to +85C) denoted by the 'I' suffix.
The PIC16LF1615-I/ST architecture is built around a 14-bit instruction word and a Harvard bus architecture with separate program and data paths, enabling single-cycle instruction execution except for branches. On-chip peripherals are interconnected through the Peripheral Pin Select (PPS) system, allowing flexible function remapping. This technical depth makes the device suitable for both general-purpose logic replacement and specialized applications such as motor control loops, where the 24-bit SMT and ZCD peripherals directly address zero-crossing detection and AC line measurement without external components.
Typical applications include small BLDC / brushed DC motor control, ceiling fan controllers, LED lighting drivers, battery-powered IoT sensor nodes, and general-purpose low-power embedded control. The integrated 10-bit ADC and PWM channels allow direct interfacing with sensors and actuators without external signal conditioning. The TSSOP-14 footprint enables space-constrained designs where QFN packages cannot be reworked by hand.
When designing with this device, ensure decoupling: a 100nF ceramic capacitor placed within 3mm of VDD, plus a 4.7uF bulk capacitor on the analog supply rail if ADC accuracy is required. The MCLR reset pin should be tied to VDD through a 10kΩ pull-up resistor with a 100nF cap to ground for reliable in-circuit programming.

Ứng dụng tiêu biểu
PIC16LF1615-I/ST phù hợp cho 6 Áp dụngs: Small BLDC Motor Control, LED Lighting Drivers, Battery-Powered IoT Sensor Nodes, Ceiling Fan / HVAC Motor Control, General-Purpose Low-Power Embedded Control, Automotive Body Electronics.
Small BLDC Motor Control
The PIC16LF1615-I/ST is ideally suited for small brushless DC motor control applications. Its integrated 24-bit Signal Measurement Timer (SMT), Zero-Cross Detection (ZCD) peripheral, and complementary waveform generator (CWG) directly drive half-bridges without external logic. The 32 MHz CPU clock provides sufficient MIPS to implement sensorless BEMF zero-crossing commutation in firmware, while the 14 KB Flash accommodates sensorless FOC or trapezoidal commutation tables. The 1.8 V minimum supply enables direct Li-ion battery operation in cordless tools and small appliances. The 14-TSSOP package footprint is small enough for integration into motor housings where QFN packages cannot be hand-reworked.

LED Lighting Drivers
The PIC16LF1615-I/ST drives dimmable LED lighting products where its 10-bit ADC reads ambient light sensors and potentiometers, while the 16-bit CCP module generates PWM dimming signals at frequencies above the audible band (>20 kHz) to eliminate flicker. The XLP™ low-power sleep modes reduce standby consumption below 50 nA, enabling always-on smart lighting fixtures that meet Energy Star and Title 24 standby limits. The 1.8 V minimum supply supports direct Li-ion emergency lighting operation. Integrated Zero-Cross Detection simplifies TRIAC dimmer interface circuitry, eliminating the optocoupler in many reference designs.

Battery-Powered IoT Sensor Nodes
The PIC16LF1615-I/ST is an excellent choice for battery-powered IoT sensor nodes where its XLP™ technology achieves nanoamp-level sleep currents below 50 nA, enabling multi-year battery life on a single coin cell. The 1.8 V to 3.6 V supply range supports direct operation from one or two alkaline cells, or from a single Li-ion / LiFePO4 cell across its entire discharge curve. The 14 KB Flash accommodates LoRaWAN class A device firmware, BLE beacon stacks, or proprietary sub-GHz protocols. Integrated 10-bit ADC and temperature indicator allow direct sensor reading without external analog front-end, reducing BOM cost for high-volume sensor products.

Ceiling Fan / HVAC Motor Control
The PIC16LF1615-I/ST controls ceiling fan and HVAC blower motors with closed-loop speed regulation. The 24-bit SMT captures AC line frequency for accurate RPM measurement, while the CWG peripheral generates phase-controlled TRIAC firing pulses for AC motor dimming. The industrial -40C to +85C temperature range supports attic and outdoor HVAC installations. The 14 KB Flash fits full-state BLDC commutation tables with temperature-compensated ramp profiles. Designers benefit from the same TSSOP-14 footprint across multiple SKUs (1614/1615/1618/1619), enabling SKU flexibility without PCB redesign.

General-Purpose Low-Power Embedded Control
The PIC16LF1615-I/ST is well suited as a general-purpose low-power MCU for embedded control applications where engineers need 8-bit simplicity, mature toolchain support, and long-term Microchip supply commitment. The Peripheral Pin Select (PPS) system allows flexible remapping of digital peripherals to any I/O pin, simplifying PCB layout. The 14 KB Flash and 1 KB RAM are sufficient for state machines, sensor fusion, keypad scanning, and simple user interfaces. Code migration within the PIC16F family is straightforward via MPLAB X IDE, with extensive application libraries and code examples available on Microchip's website.

Automotive Body Electronics
The PIC16LF1615-I/ST (industrial grade -40C to +85C) is suitable for non-safety automotive body electronics such as interior lighting controllers, seat position sensors, and accessory multiplexers where its 10-bit ADC reads position sensors and the CWG drives small motor loads. Note that this 'I' (industrial) grade variant is NOT AEC-Q100 qualified - for AEC-Q100 Grade 0 or Grade 1 automotive applications, designers should select the PIC16F1615-E/ST (extended) or PIC16F1615-HV automotive variants. The TSSOP-14 footprint allows placement inside tight automotive enclosures where hand-reworkability is required.

Ghi chú thiết kế
Place a 100nF ceramic decoupling capacitor within 3 mm of the VDD pin (pin 1) and a 4.7uF to 10uF bulk capacitor near the VDD rail. For ADC accuracy better than 1 LSB, add a separate 100nF cap on the AVdd pin if used. The 'LF' variant operating at 1.8 V requires low-Voltage-dropout (LDO) regulation - MCP1700 is recommended for its 250 mV dropout at 250 mA load, enabling single Li-ion cell operation down to 3.0 V Vbat.
The 14-TSSOP package has a 0.65 mm pin pitch requiring fine-pitch SMT assembly. Use NSMD (Non-Solder Mask Defined) pads with 0.30 mm pad width for reliable solder joints. Stencil apertures should be 0.40 mm wide with 100um thickness for lead-free reflow. Hand-rework is possible with a fine-tip soldering iron (1 mm chisel) but requires flux and careful thermal management to avoid pad lifting.
Do NOT confuse the 'LF' (1.8 V to 3.6 V) variant with the 'F' variant (2.5 V to 5.5 V) - they share the same pinout but different electrical characteristics. Programming voltage thresholds differ; using the wrong datasheet parameters will cause read failures or programming errors. Always verify the exact ordering code (PIC16LF1615 vs PIC16F1615) before PCB assembly. The MCLR pin (pin 4) requires a 10kΩ pull-up to VDD for normal operation; leaving it floating causes unpredictable reset behavior.
