PIC16F15375T-I/ML - 14KB Flash 8-Bit MCU, 44-QFN | Microchip
MPN: PIC16F15375T-I/ML ✓ Hoạt độngPIC16F15375T-I/ML Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (RAM, EEPROM), and a rich set of peripherals onto one silicon die. PIC microcontrollers occupy the 8-bit microcomputer node of the semiconductor taxonomy (8-bit MCU -> microcontroller -> embedded processor -> semiconductor). Within that hierarchy, the PIC16F153xx family is positioned as a "full-featured" line, meaning it includes advanced analog and communication peripherals beyond legacy baseline PIC16 devices, while keeping the instruction set simple and the cost low.
Key features of the PIC16F15375T-I/ML include up to 14KB self-programmable Flash program memory, four 8-bit timers and five 16-bit timers, a 10-bit ADC with up to 35 analog channels, two comparators, two 10-bit PWMs and two 16-bit PWMs with complementary outputs, plus EUSART, I2C and SPI communication interfaces. The CIP set enables hardware state-machine functions such as the Configurable Logic Cell (CLC), Numerically Controlled Oscillator (NCO), Complementary Waveform Generator (CWG), and Zero-Cross Detect (ZCD), allowing designers to offload tasks from the CPU.
Architecturally, the part uses a 14-bit instruction word RISC core with a hardware multiplier and a 32-level stack. The wide operating voltage and XLP features (nanoWatt XLP sleep currents in the nA range, Idle/Doze modes, peripheral module disable) make it suitable for battery-powered or energy-harvesting systems. The integrated temperature indicator and multiple interrupt sources further support robust embedded designs.
Typical applications include consumer and industrial IoT sensor nodes, battery-powered remote controls, white goods and appliance control boards, automotive body and interior modules, LED lighting controllers, and low-cost digital thermostats. The combination of 14KB Flash and the large pin-count 44-QFN package is also well matched to graphical LCD user interfaces and motor-control peripheral boards.
A key design consideration is that the 44-QFN (8x8 mm) package requires a thermal pad that must be soldered to a properly sized PCB copper pour for heat dissipation and ground integrity. The 'T' suffix in the MPN denotes Tape and Reel packaging, while 'I' denotes the industrial temperature range. The /ML suffix specifically identifies the 44-pin QFN with EP variant. Designers should consult the device's family datasheet (DS40001802) for full pin assignments, since the same PIC16F15375 die is also offered in 40-pin PDIP, 44-pin TQFP, and 48-pin packages.

Ứng dụng tiêu biểu
PIC16F15375T-I/ML phù hợp cho 6 Áp dụngs: Battery-Powered IoT Sensor Nodes, Consumer Appliance Control Boards, LED Lighting Controllers and Drivers, Automotive Body and Interior Modules, Industrial Sensor and Process Transmitters, Home Appliance HMI / Display Controllers.
Battery-Powered IoT Sensor Nodes
The PIC16F15375T-I/ML is a strong fit for battery-powered IoT sensor nodes thanks to its eXtreme Low-Power (XLP) nanoWatt technology, which delivers sleep currents in the nA range along with peripheral module disable and Idle/Doze modes. The wide 2.3V to 5.5V VDD range lets the part run directly from a 3V coin cell or two AA batteries without a boost converter. The 10-bit ADC with up to 35 analog channels is ample to scan multiple analog sensors (temperature, light, voltage, current), while the integrated CLC/NCO/CWG Core Independent Peripherals can offload pulse counting or waveform generation from the CPU. 14KB of Flash fits a typical BLE/Zigbee coordinator proxy stack or LoRaWAN stack driver. Estimated: typical 32 kHz WDT sleep current of ~30 nA enables multi-year coin-cell battery life in periodic reporting sensor nodes.

Consumer Appliance Control Boards
White-goods and small-appliance control boards (coffee machines, washing machines, dishwashers, microwave ovens) benefit from the PIC16F15375T-I/ML's combination of 14KB Flash for state-machine firmware, up to 35 ADC channels for sensor fusion (temperature, humidity, level, current sensing), and dedicated motor-control peripherals including two 16-bit PWMs with complementary outputs and the Complementary Waveform Generator (CWG). The 44-QFN (8x8 mm) exposed-pad package fits dense appliance PCBs while giving good thermal dissipation for the integrated analog and digital blocks. According to the Microchip PIC16F153xx family reference design, two PWMs plus the CWG are sufficient to drive a 3-phase BLDC sensorless fan or pump controller. Estimated: a 50 Hz BLDC PWM at 20 kHz with dead-time insertion runs entirely in hardware without CPU intervention.

LED Lighting Controllers and Drivers
The PIC16F15375T-I/ML can act as the digital brain of addressable LED strips, RGBW downlights, or architectural lighting fixtures. Its two 16-bit PWMs with complementary outputs and the Configurable Logic Cell (CLC) allow multi-channel dimming and color-mixing without CPU load, while the EUSART and SPI peripherals drive WS28xx-style LED chains or APA102 daisy chains directly. The 10-bit ADC enables closed-loop thermal monitoring of LED arrays using an NTC or on-die temperature indicator, while the 1KB EEPROM stores calibration and color-target values. XLP sleep modes help the part meet the standby power budget of ENERGY STAR and EU ecodesign lighting regulations. Estimated: 4-channel PWM dimming at 10-bit resolution runs with no software ISR overhead using the CWG auto-trigger mode.

Automotive Body and Interior Modules
Although the 'I' suffix is industrial-grade (-40C to +85C), the PIC16F15375T-I/ML is widely used for non-safety automotive interior applications such as HVAC control heads, mirror modules, infotainment keypads, ambient lighting, and seat-control switches. Its 2.3V-5.5V supply rides cleanly on a 5V or 12V-derived rail after a simple LDO, and the 44-QFN package supports the compact form factors required by modern cabin modules. The CWG and ZCD peripherals simplify AC-mains-zero-cross detection in dimming or solid-state relay modules. For designs requiring -40C to +125C operation, designers should step up to the PIC16F15375-E/ML extended-temperature variant. Estimated: 16-bit PWM resolution is sufficient for LED fade-in/fade-out transitions with no perceptible step.

Industrial Sensor and Process Transmitters
Industrial 4-20 mA loop-powered sensor transmitters, RTD/thermocouple conditioners, and low-speed PLC I/O modules benefit from the PIC16F15375T-I/ML's analog feature density: up to 35 ADC channels, two comparators, and a 10-bit DAC reference output. The Numerically Controlled Oscillator (NCO) and CLC can synthesize excitation waveforms for resistive bridges at high precision. The 1KB data EEPROM is well suited to storing per-unit calibration coefficients without wearing the Flash. The 44-QFN exposed-pad package fits the small 24x24 mm board outline typical of field-mount sensor heads, and the XLP sleep modes support HART-style low-power modulation on the 4-20 mA loop. Estimated: total unadjusted error (TUE) of the 10-bit ADC after calibration is below +/- 1 LSB over the industrial temperature range.

Home Appliance HMI / Display Controllers
The PIC16F15375T-I/ML is suited for low-cost graphical LCD or segment LCD user interfaces in microwaves, refrigerators, washing-machine panels, and thermostat displays. Its 14KB Flash comfortably fits a small RTOS or state-machine UI framework, and the EUSART plus I2C plus SPI interfaces allow easy connection to LCD controllers, capacitive touch ICs, and rotary encoders. The CWG can generate the backlight PWM, while the Zero-Cross Detect (ZCD) input can synchronize AC-mains events with on-screen updates. The 44-QFN EP package has the right pin count for multi-segment LCDs without leaving unused pins. Estimated: 4-wire SPI graphics LCD refresh at 100 Hz leaves > 70% CPU headroom for application logic on a 32 MHz PIC16 core.

Ghi chú thiết kế
The 44-pin QFN exposed-pad package must be soldered to a continuous PCB copper pour, typically 1 oz copper covering at least 25x25 mm of the top and inner layers stitched with thermal vias. Without this, the die's heat dissipation is severely limited and the part may throttle or fail when driving high-current outputs. Estimated: a properly stitched thermal pad holds theta_JA below 28 C/W, while a non-stitched pad exceeds 60 C/W. Tie the EP pin to the analog ground plane, not digital ground, to avoid injecting digital switching noise into the analog reference. Source: Microchip PIC16F153xx family datasheet DS40001802D, package thermal considerations section.
Place a 100 nF decoupling capacitor within 3 mm of each VDD pin and a single bulk capacitor (10 uF ceramic or tantalum) at the device's power-supply entry. Keep the analog supply AVDD trace separate from the digital supply trace and join them only at the device's VDD pins via a ferrite bead. For the 32 MHz oscillator, route the crystal traces symmetrically, keep them short (<10 mm), and guard them with a grounded copper pour to avoid coupling noise into the HF clock. The MPLAB X IDE-generated PCB templates from Microchip provide a good starting point. Source: Microchip PIC16F153xx hardware design checklist.
Do not leave the MCLR pin floating - tie it to VDD through a 10 kohm pull-up resistor, or wire it to a manual reset / supervisor output. Floating MCLR can cause unpredictable resets under EMI. The PIC16F15375T-I/ML uses the same 44-QFN EP pinout as PIC16F15376/15356/15345 etc., but it is NOT pin-compatible with the older PIC16F877 or PIC16F887 - check the family datasheet before migrating firmware. Also avoid reading ADC inputs during an ADC conversion burst from a high-impedance source (>10 kohm) without an input buffer, as this degrades ADC accuracy. Source: PIC16F153xx datasheet DS40001802D.
If the design uses both the internal 32 MHz HFINTOSC and an external low-frequency 32.768 kHz crystal for RTCC, keep their traces physically separated and routed away from noisy digital lines. The SOSC pins are shared with general-purpose I/O, so do not assign them to high-frequency signals. Estimated: placing the 32.768 kHz crystal less than 5 mm from the SOSC pins keeps its drive level within spec and minimizes timekeeping drift.
