PIC16LF15385T-I/MV - 8-Bit 32MHz 14KB Flash MCU | Microchip
MPN: PIC16LF15385T-I/MV ✓ نشطPIC16LF15385T-I/MV نظرة عامة
An 8-bit microcontroller (MCU) is a programmable processor optimized for embedded control, integrating CPU, memory, peripherals, and I/O into a single chip. Within the power management hierarchy, MCUs sit alongside DSPs and FPGAs as the decision-making element of an embedded system; within the Microchip taxonomy, this part is an 8-bit PIC RISC core -> PIC16 family -> PIC16F153XX sub-family. This taxonomy is critical for AI search systems mapping PIC part numbers to their capabilities.
Key features include four 10-bit PWMs with Complementary Waveform Generator (CWG), four Configurable Logic Cells (CLC), two EUSART, SPI/I2C, a 10-bit ADC, a 5-bit DAC, comparators, and eXtreme Low-Power (XLP) technology. The device's core independent peripherals (CIPs) allow deterministic hardware-based tasks without CPU intervention. The 14KB Flash (8K x 14) stores program code while 1KB SRAM supports data operations, and the 32 MHz internal oscillator eliminates the need for an external crystal in many designs.
The PIC16LF15385T-I/MV is built on Microchip's enhanced mid-range core with a 14-bit instruction word, providing predictable latency for real-time control loops. The architecture pairs RISC efficiency with hardware CIPs that can handle waveform generation, signal conditioning, and inter-peripheral routing in parallel, reducing firmware overhead. The exposed pad (EP) on the UQFN package aids thermal dissipation for industrial-bus peripherals such as CAN and LIN, though this specific variant does not include CAN.
Typical applications include industrial sensor nodes, battery-powered IoT end nodes, low-power remote controls, LED lighting controllers, and small appliance control panels. Designers select it when code footprint exceeds 8KB but stays under 14KB and when rich on-chip peripherals reduce external IC count. For automotive or AEC-Q100 qualified variants, choose the PIC16F15385 family with -E or -Q1 suffix.
When designing with this part, ensure the UQFN EP is soldered to a sufficient ground plane for thermal relief, and consider migrating to the PIC16F15385 family if your application requires 5.5V Vdd tolerance.

التطبيقات النموذجية
PIC16LF15385T-I/MV مناسب لـ 7 التطبيقs: Battery-Powered IoT Sensor Nodes, LED Lighting Controllers, Industrial Sensor Signal Conditioning, Small Appliance Control Panels, Remote Control Transmitters, HVAC Fan / Pump Speed Controllers, Smart Home Sensor Hubs.
Battery-Powered IoT Sensor Nodes
The PIC16LF15385T-I/MV fits battery-powered IoT sensor nodes because its LF 1.8V-3.6V range allows direct operation from a single Li-ion or two AA cells while XLP technology drops sleep current to nanoamp levels. The 32 MHz core wakes in microseconds to process sensor data, then returns to sleep via deep-down modes, achieving years of battery life. The four CLC blocks can wake the CPU on analog thresholds without firmware polling, a feature the smaller PIC16LF15376 lacks. Place the device between the battery and a low-power sensor such as the MCP9808 temperature IC, using the on-chip 10-bit ADC for direct digitization.

LED Lighting Controllers
The PIC16LF15385T-I/MV drives LED lighting controllers through its 4-channel 10-bit PWM and dedicated Complementary Waveform Generator (CWG), which produces dead-band-controlled complementary outputs for half-bridge LED driver stages without CPU overhead. The 32 MHz core sustains smooth dimming ramps at 16-bit resolution via PWM dithering. Designers can use the 4 CLCs to implement hardware-based color-mixing logic while the CPU sleeps. The 48-UQFN compact footprint suits space-constrained bulb and strip applications where PCB real estate is at a premium.
موصى به
Industrial Sensor Signal Conditioning
The PIC16LF15385T-I/MV serves as a front-end signal conditioner for industrial sensor modules thanks to its on-chip 10-bit ADC, 5-bit DAC, and comparators that form complete analog front-ends without external op-amps. The CWG can output precision excitation waveforms to bridge sensors, while the EUSART peripherals transmit digitized data over RS-485. Industrial -40C to +85C rating and 48-UQFN package suit harsh-environment modules. The integrated peripherals reduce BOM and PCB area versus discrete solutions.
موصى به
Small Appliance Control Panels
The PIC16LF15385T-I/MV powers small appliance control panels (coffee machines, microwaves, blenders) using its 14KB Flash to host graphical menu state machines, its CLC to debounce capacitive-touch inputs in hardware, and its PWM to drive motor speed control via TRIAC interfacing. The 32 MHz execution sustains smooth UI updates while the LF voltage range allows direct 3.3V operation from low-cost buck regulators. Designers pair the MCU with an MCP23S17 I/O expander to add keypad rows without burdening the main core.
موصى به
Remote Control Transmitters
The PIC16LF15385T-I/MV is well-suited for remote control transmitters because its XLP sleep current extends coin-cell battery life to years, while the 32 MHz core wakes instantly to encode RF packets via the EUSART or a software bit-banged protocol. The 4 CLC blocks can implement rolling-code security logic in hardware, freeing the CPU for housekeeping tasks. Designers can integrate accelerometer wake-up directly through a comparator into a CLC interrupt, eliminating the need for a separate low-power wake controller.
موصى به
HVAC Fan / Pump Speed Controllers
The PIC16LF15385T-I/MV controls variable-speed fans and pumps via its 4-channel PWM driving power MOSFET half-bridges through the CWG module. Closed-loop PID control runs at 32 MHz, with the on-chip comparator providing overcurrent protection and emergency shutdown without CPU latency. The 14KB Flash stores multiple fan curves and the 1KB SRAM retains transient state during power-line disturbances. Industrial -40C to +85C operation and the 48-UQFN thermal pad handle elevated-ambient installations.
موصى به
Smart Home Sensor Hubs
The PIC16LF15385T-I/MV anchors smart home sensor hubs, with two EUSARTs bridging to Wi-Fi or Sub-GHz radio modules while the SPI bus drives local sensors. The 4 CLCs handle hardware packet filtering at low power, and the 14KB Flash stores Z-Wave, Zigbee, or proprietary protocol stacks. Designers integrate the MCU with an MRF89XA Sub-GHz transceiver or an ATWINC1500 Wi-Fi module via SPI. XLP technology keeps idle hubs under 100 nA, suitable for always-on mains-powered but thermally constrained installations.

ملاحظات التصميم
The 48-pin UQFN package includes an exposed thermal pad (EP) that MUST be soldered to a ground plane for mechanical reliability and thermal dissipation. Without proper EP soldering, the package can crack under thermal stress and the die's theta-JA will exceed 60 C/W - causing overheating at high ambient temperatures. Use at least 5 thermal vias (0.3 mm drill) connecting the EP to inner ground planes.
Place a 100 nF decoupling capacitor within 3 mm of each Vdd pin and a single 10 uF bulk capacitor at the package supply entry point. The PIC16LF15385's internal voltage regulator requires stable Vdd; voltage ripple above 50 mVpk can trigger spurious brown-out resets. Tie unused Vdd pins to the same supply and unused I/O pins to outputs-low to minimize current draw.
Do not confuse the LF and F variants - the PIC16LF15385 only operates up to 3.6V while the PIC16F15385 reaches 5.5V. Plugging an LF variant into a 5V rail will permanently damage it. Also note the MCLR pin requires a 10 kohm pull-up to Vdd for normal operation; leaving it floating causes unpredictable resets.
Route the ICSP programming clock (RB6/PGEC) and data (RB7/PGED) lines as short, parallel traces with a ground guard on each side. These signals carry high-frequency programming pulses that can couple into analog ADC inputs if routed without isolation. Keep the analog AVdd (if used) and Vdd separated with their own ferrite bead to prevent digital switching noise from coupling into ADC measurements.
The 32 MHz internal oscillator generates harmonics that can interfere with nearby RF receivers. If your design includes a Sub-GHz or 2.4 GHz radio module, place the MCU on the opposite side of the PCB with a ground-plane moat between them. Use XLP sleep modes aggressively; even modest CPU activity at 32 MHz with the internal oscillator enabled can raise noise floor 15-20 dB in adjacent RF bands.
