MPN: PIC16LF15375T-I/MV ✓ Hoạt độngPIC16LF15375T-I/MV Tóm tắt
A PIC (Peripheral Interface Controller) microcontroller is a Harvard-architecture 8-bit RISC MCU that combines a CPU core, non-volatile Flash program memory, RAM, and a wide peripheral set on a single die. Within the broader taxonomy, the PIC16 sits between the smaller PIC10/12/16 baseline families and the PIC18/dsPIC33 high-performance families, targeting cost-sensitive embedded designs that need moderate memory, low power, and rich analog/digital peripherals. The "LF" prefix denotes a wide-voltage 1.8V-3.6V operating range tuned for battery-powered systems, and the "XLP" (eXtreme Low Power) family adds nanoWatt technology for sleep currents in the nanoamp range.
Key features of the PIC16LF15375T-I/MV include 14KB (8K x 14) self-programmable Flash with Flash program memory visibility, 1KB RAM, 256 bytes of EEPROM-like data, a 10-bit ADC, two 5-bit DACs and a 10-bit DAC, four 16-bit PWMs, a comparator, a Complementary Waveform Generator (CWG), four Configurable Logic Cells (CLC), two EUSART, SPI, and I2C interfaces. The device supports up to 36 I/O pins on the 40-pin UQFN and includes multiple clock sources from 31kHz LFINT to 32MHz HFINT.
Technically, the PIC16LF15375 uses an enhanced mid-range 8-bit CPU core with a 14-bit instruction word, hardware multiply, and a 32-level hardware stack. The eXtreme Low Power (XLP) modes include Sleep, Idle, and Doze, plus peripheral module disable, allowing engineers to drop system current below 100 nA in deep Sleep with RTC running.
Typical applications include low-power IoT sensor nodes, battery-powered home automation, smart wearables, remote controls, wireless sensor end nodes, energy-harvesting devices, and small industrial controllers. Design with 1.8V-3.6V supply, ensure decoupling caps are placed within 3mm of VDD pins, and leverage the CWG and CLC blocks to offload real-time tasks from the CPU.

Battery-Powered IoT Sensor Nodes
The PIC16LF15375T-I/MV is purpose-built for battery-powered IoT sensor nodes that spend most of their time sleeping between measurements. Its XLP nanoWatt Sleep current (below 100 nA with RTC running) combined with the 1.8V-3.6V wide voltage range lets it run directly from a single CR2032, two AA cells, or a 1S Li-ion/LiPo battery. The CWG and 4x CLC blocks implement sensor signal conditioning, threshold detection, and PWM-driven sensor excitation without waking the CPU, while the 10-bit ADC and 5/10-bit DACs handle analog sensing. The 32MHz HFINTOSC provides enough throughput for periodic BLE/SX127x-LoRa driver tasks, and the 14KB Flash comfortably fits an RTOS-free state-machine firmware plus OTA boot loader. Use the LFINTOSC (31 kHz) for ultra-low-power timekeeping and let the on-chip comparator trigger peripheral-driven wake-ups.

Smart Home Automation Devices
The PIC16LF15375T-I/MV fits smart home automation devices including wireless dimmer switches, sensor hubs, occupancy sensors, and HVAC controllers. Its 36 I/O pins can directly drive multiple TRIAC or MOSFET outputs, multi-button capacitive touch panels, and RGB LED status indicators, while the 4x 16-bit PWMs give precise dimming and motor control without software overhead. The two EUSART blocks allow simultaneous connectivity to a wireless module (LoRa, sub-GHz, or BLE) and a wired debug/log channel. The eXtreme Low Power Sleep current under 100 nA lets battery-powered wall switches run for years on a CR2032, and the on-chip CLC lets you implement logic glue for safety interlocks without external gates.

Industrial Sensor Transmitters
The PIC16LF15375T-I/MV is well suited for industrial 4-20mA sensor transmitters, RTD/thermocouple conditioners, and pressure/flow transmitters operating from a regulated 24V industrial bus with local regulation. The 10-bit ADC combined with the on-chip 5-bit DAC enables software-defined scaling and sensor linearization, while the on-chip comparator drives fast over-range alarms. The 14KB Flash is sufficient for IEC 61131-3-style function blocks, polynomial linearization tables, and HART or IO-Link state machines. The CLC implements logic for sensor-failure detection and watchdog supervision, and the 32MHz core can serve the periodic interrupt-driven transducer read while leaving headroom for diagnostic routines.

Wearable Health & Fitness Devices
The PIC16LF15375T-I/MV powers wearable health and fitness devices such as fitness bands, smartwatches for sub-displays, pulse-oximeter probes, and posture-correction wearables. Its low Sleep current and LFINTOSC-driven RTC enable multi-day battery life with continuous 24-hour step counting, and the CLC-driven peripheral logic reads PPG or accelerometer interrupts without CPU intervention. The on-chip 10-bit DAC supports bioimpedance drive waveforms, and the small 5x5 mm UQFN package fits comfortably under a watch crown. Multiple PWMs drive haptic feedback motors and RGB indicator LEDs, and the SPI/I2C buses connect directly to low-energy BLE SoCs for radio offloading.

Remote Controls & HMI Keypads
The PIC16LF15375T-I/MV drives universal remote controls, IR/RF keypads, and battery-powered HMI panels that wake on touch or button press. The integrated CLC implements capacitive touch scanning and IR carrier modulation in hardware, freeing the CPU to handle protocol stacks for NEC/RC5/RC6 IR or proprietary sub-GHz RF. The XLP Sleep below 100 nA combined with peripheral wake-on-change means a 2-button remote can operate for 5+ years on a single CR2032 cell. The two EUSARTs let a multi-protocol remote bridge IR, BLE, and sub-GHz simultaneously.

Energy-Harvesting Wireless End Nodes
The PIC16LF15375T-I/MV is an excellent fit for energy-harvesting wireless sensor end nodes such as self-powered BLE beacons, solar-powered field sensors, and vibration-energy HVAC monitors. Its sub-100 nA Sleep current is critical when the available energy budget is the bottleneck, and the wide 1.8V-3.6V supply range allows direct connection to harvesters with MPPT rectifiers. The CWG drives piezo transducer harvesting, the 4x CLC blocks implement threshold-based wake-up logic, and the on-chip 10-bit ADC and comparator handle periodic battery-voltage and ambient-light sensing. The 14KB Flash supports lightweight proprietary or BLE/Sub-GHz stacks.

Automotive Body Electronics & Lighting
The PIC16LF15375T-I/MV is suitable for automotive body electronics such as interior LED lighting controllers, mirror-glare control modules, seat-position encoders, and HVAC flap actuators when paired with an external CAN/LIN transceiver. The CWG module drives LED strings with hardware dead-band control, the 4 PWMs drive RGB or tunable-white lighting with smooth fades, and the 32MHz core executes LIN 2.x protocol stacks for body networks. The LF voltage range lets the part run from a regulated 3.3 V rail shared with other body controllers. For AEC-Q100 automotive-qualified parts, select the PIC16LF15375T-I/MVAUTO equivalent; the standard "I" industrial-grade part in this MPN is rated for -40C to +85C.

Ghi chú thiết kế
Decouple each VDD/VSS pair with a 100 nF ceramic capacitor placed within 3 mm of the IC pins, and add a bulk 1 uF to 10 uF capacitor at the package supply entry. For battery-powered designs using the XLP Sleep mode below 100 nA, use a low-leakage ceramic cap (C0G/NP0) on VDD to avoid leakage current dominating the sleep budget. Verify regulator turn-on time vs the LFINTOSC wake-up latency.
The 40-UQFN (5x5 mm) package exposes a thermal pad (EP) on the underside that MUST be soldered to a VSS plane for both electrical grounding and thermal dissipation. Use at least 4 thermal vias under the EP to a bottom-layer VSS pour, and avoid cutting the top-layer ground plane around the package - this degrades thermal performance and causes ground bounce during PWM switching.
Route ICSPCLK and ICSPDAT traces as a short dedicated pair with no series resistors on the production PCB - place optional isolation resistors (4.7 kohm) only on development boards so they can be removed in production. Place the ICSP header at the board edge with a 6-pin standard 0.1" header layout (MCLR/VDD/GND/ICSPCLK/ICSPDAT/NC) for compatibility with PICkit programmers and Microchip MPLAB SNAP.
Avoid leaving unused I/O pins floating - configure them as outputs driving low, or inputs with the internal weak pull-up enabled, to prevent CMOS input-stage shoot-through current. Also ensure the MCLR pin (pin 1) has a 10 kohm pull-up to VDD for normal operation; omitting the pull-up causes erratic resets. Estimated: total quiescent current from 36 floating I/O can exceed 100 uA, dwarfing the XLP Sleep current specification.
When using the CWG block to drive high-speed switching outputs (e.g., piezo or MOSFET gates), keep the CWG output traces short and add a 33 ohm series damping resistor close to the CWG pin to suppress ringing. For PWM-driven LED strings, route the high-current return path on a dedicated layer adjacent to the driver pin to minimize ground-loop noise coupling into the analog ADC inputs.
