PIC16LF15375-I/MV 概述
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, data RAM, and a set of peripherals on one die. Within the broader semiconductor taxonomy, an 8-bit MCU sits below 16-bit and 32-bit MCUs in computational throughput but is favored for cost-sensitive, low-power, deterministic-control tasks. The PIC16F153xx family is Microchip's mainstream 8-bit line that combines classic PIC simplicity with modern Core Independent Peripherals (CIPs).
Key features of the PIC16LF15375 include four 10-bit PWM outputs, a comparator, a 5-bit/8-bit DAC, a 10-bit ADC with automatic acquisition, a Complementary Waveform Generator (CWG), four Configurable Logic Cells (CLC), two EUSART, one SPI and one I²C interface, plus 35 I/O pins. The device integrates nanoWatt XLP technology with currents as low as 30 nA in sleep, enabling battery-powered designs with multi-year lifetimes.
The PIC16LF15375 uses an enhanced mid-range 8-bit PIC16 core with a hardware multiplier, a single-cycle instruction pipeline, and 49 instructions including hardware stack and shadow register support. Peripherals can operate autonomously via Configurable Logic Cells (CLC) and the Peripheral Pin Select (PPS) system, offloading tasks from the CPU and reducing active-mode current. Internal voltage reference, temperature indicator and Zero-Cross Detect further expand analog capability.
Typical applications include IoT sensor nodes, low-power wireless endpoints, battery-powered consumer devices, home automation, portable medical peripherals, LED lighting controllers, and industrial sensor hubs. The combination of deep sleep currents under 50 nA, fast wake-up, and rich analog peripherals makes this MCU especially attractive for energy-harvesting designs.
When designing with this device, route the exposed pad (EP) to a contiguous ground plane for thermal and electrical performance, and respect the 1.8 V minimum Vdd to retain LF low-power characteristics. Selecting the 'F' (Flash, 1.8-5.5 V) variant widens supply tolerance if battery plus USB charging is required.

典型应用
PIC16LF15375-I/MV 适用于 6 应用s: Battery-Powered IoT Sensor Node, Low-Power Wireless Remote Control, Home Automation / Smart Lighting Controller, Portable Medical Peripheral, Industrial Sensor Hub / Modbus Node, Small Appliance Control / Fan / Pump Driver.
Battery-Powered IoT Sensor Node
The PIC16LF15375-I/MV is a strong fit for battery-powered IoT sensor nodes because its nanoWatt XLP technology reaches typical deep-sleep currents of ~30 nA, allowing 2xAAA cells or coin cells to power the node for years. The 32 MHz CPU executes sensor reads, peripheral events, and protocol stacks quickly so the device returns to sleep within milliseconds. With 1 KB SRAM and 14 KB Flash it accommodates small wireless stacks (e.g., MiWi or proprietary sub-GHz drivers) and the four CLCs handle wake-on-event signal conditioning without waking the CPU.
推荐
Low-Power Wireless Remote Control
For handheld remote controls (RF, IR, BLE-proxied) the PIC16LF15375-I/MV provides four 10-bit PWM channels for LED backlighting and haptic drive, four Configurable Logic Cells (CLC) that offload button-debounce and rotary-encoder decoding from the CPU, and deep-sleep currents under 50 nA that allow CR2032 cells to last the shelf life of the product. The 35 I/O and Peripheral Pin Select (PPS) route EUSART/SPI to almost any pin, simplifying PCB layout of a cramped remote housing.
推荐
Home Automation / Smart Lighting Controller
Smart-lighting and home-automation hubs benefit from the PIC16LF15375-I/MV's 10-bit ADC for current/voltage monitoring, the CWG (Complementary Waveform Generator) for zero-cross TRIAC drive, and the comparator for zero-cross detection in dimmer topologies. The 1.8-3.6 V LF supply range aligns with 3.3 V digital rails in mains-isolated lighting converters, while the rich communication block (2 x EUSART, SPI, I²C) bridges to wireless MCUs and analog front-ends without glue logic.
推荐
Portable Medical Peripheral
Portable medical peripherals such as pulse-oximeter fingertip probes, digital thermometers, and pill-dispenser actuators take advantage of the PIC16LF15375-I/MV's low XLP sleep current for years-of-shelf-life battery life, its 10-bit ADC for battery and sensor measurements, and its 35 I/O for driving LEDs, buzzer and segment displays. Deterministic PIC16 interrupt latency keeps sensor acquisition timing precise, which is essential for medical-grade measurement repeatability.
推荐
Industrial Sensor Hub / Modbus Node
In industrial sensor-hub and Modbus RTU nodes, the PIC16LF15375-I/MV provides a 32 MHz CPU, 14 KB Flash and 2 x EUSART for RS-485 Modbus master/slave communication, while the comparator and 10-bit ADC handle 4-20 mA or 0-10 V analog sensor inputs. The 'I' industrial temperature grade (-40 °C to +85 °C) and 1.8-3.6 V Vdd tolerate factory-floor 24 V → 3.3 V buck-derived rails. The 40-UQFN exposed pad simplifies ground-plane routing for noisy industrial enclosures.
推荐
Small Appliance Control / Fan / Pump Driver
The PIC16LF15375-I/MV's four PWM channels combined with the CWG (Complementary Waveform Generator) drive small BLDC fans, solenoid pumps, and brushed DC loads in kitchen and personal-care appliances. The 1 KB SRAM and 14 KB Flash fit state-machine motor firmware, the comparator supports back-EMF zero-cross detection, and the 'I' industrial temperature grade survives under-hood and bathroom environments. The exposed pad on the UQFN-40 efficiently dissipates the modest power dissipation of an 8-bit MCU driving FET gates.

设计说明
The 40-pin UQFN (MV) package exposes a die pad on the underside that MUST be soldered to a contiguous Vss ground plane. Estimated: the pad reduces thermal resistance by approximately 10-15 °C/W versus an unsoldered pad. Use at least five thermal vias (0.3 mm drill, 0.5 mm pitch) under the EP and stitch the perimeter with 0402 decoupling caps. Add a 100 nF X7R ceramic on each Vdd/Vss pin pair (pins 7/8 and 35/40) within 2 mm of the package.
Operate the PIC16LF15375-I/MV from a clean 1.8 V to 3.6 V rail. Estimated: the LF variant draws ~30 nA in deep sleep and roughly 1.5 mA/MIPS active, so battery life is dominated by active-mode bursts. Add a 10 µF bulk + 100 nF decoupling cap pair at the MCU's Vdd pins. If you need 5 V tolerance on any pin, choose the PIC16F15375 (F, 1.8-5.5 V) variant instead.
Do not leave the MCLR/RA3 pin floating - tie it to Vdd through a 10 kΩ resistor for normal operation or drive it with the programmer's Vpp during ICD. Avoid leaving unused I/O as analog inputs (they draw extra current); set them as digital outputs driving low. The PPS system must be unlocked before reconfiguring peripheral-to-pin mappings, otherwise the writes are ignored silently.
When routing EUSART RS-485 at high baud rates, place a 100 Ω termination at the bus ends and route the differential pair as a matched-length pair (delta < 2 mm). For SPI at > 8 MHz add a 33 Ω damping resistor in series with SCK/SDO near the master. Keep digital switching traces (PWM, CWG) at least 3 mm away from the analog ADC traces to avoid coupled noise on the 10-bit ADC readings.
Estimated: at 32 MHz active and 3.3 V, the PIC16LF15375-I/MV draws roughly 5-7 mA (16-23 mW), so self-heating is negligible for the UQFN-40 with theta_JA around 35-40 °C/W on a 2-layer board. Even at +85 °C ambient the junction rises only ~1 °C. Sleep-mode power is so low that thermal concerns are essentially absent in the LF variant.
合规信息
RoHS compliant per Microchip product page. The 'I' suffix indicates industrial temperature grade -40 °C to +85 °C. For -40 °C to +125 °C extended grade choose the 'E' suffix variant (PIC16LF15375-E/PT or PIC16LF15375-E/MV).
