PIC16F15375-E/MVVAO - 14KB Flash 32MHz XLP 8-bit MCU | Microchip
MPN： PIC16F15375-E/MVVAO ✓ 啟用中PIC16F15375-E/MVVAO 概覽
The PIC16F15375 belongs to the broader PIC16(L)F153xx family of 8-bit microcontrollers, which sit within Microchip's mid-range PIC16 architecture hierarchy. An 8-bit MCU executes instructions on 8-bit data widths, using a Harvard memory architecture and a RISC-based instruction set; PIC16 devices in particular are recognized in the embedded industry for their deterministic timing, ease of programming in C or assembly through MPLAB X IDE, and a rich ecosystem of Core Independent Peripherals (CIPs). The XLP designation specifically targets battery-powered and energy-harvesting designs by integrating nanoWatt technology, deep-sleep modes drawing single-digit microamps, and peripheral operation while the CPU is halted.
Key features include 38 digital I/O pins, four 10-bit PWMs with complementary outputs, two comparators, a 5-bit DAC, a 10-bit ADC with automatic averaging, a Complementary Waveform Generator (CWG), two EUSART peripherals, two SPI/I2C interfaces, and 32MHz internal oscillator operation. The CIP mix (CLC, NCO, CWG, PWM, ADC with computation) allows complex signal generation and feedback loops without CPU intervention, reducing power and code complexity.
Typical applications include automotive body electronics, sensor nodes, LED lighting controllers, low-power IoT endpoints, battery management peripherals, and industrial control loops. The combination of 32MHz performance, 14KB Flash, and XLP sleep currents below 1 uA makes the device suitable for AEC-Q100 automotive subsystems such as HVAC controls, mirror modules, ambient lighting, and seat controllers.

典型應用
PIC16F15375-E/MVVAO 適用於 7 應用s: Automotive Body Electronics Modules, Battery-Powered IoT Sensor Nodes, Industrial Control & Sensor Signal Conditioning, LED Lighting & Backlight Controllers, HVAC & Climate Control Subsystems, Medical Monitoring Accessories, Consumer Appliance Control Boards.
Automotive Body Electronics Modules
The PIC16F15375-E/MVVAO's AEC-Q100 VAO qualification and -40C to +125C extended temperature range make it well suited for body control modules distributed throughout modern vehicles. Its 38 digital I/O pins can read multiple switch contacts, drive LED indicators, and actuate relays in door modules, mirror controllers, and ambient-lighting ECUs. The Complementary Waveform Generator (CWG) and four 10-bit PWMs enable driving half-bridge FET stages for small motors and dimmable backlights without CPU overhead. Combined with the 5V-tolerant 32MHz core and 2.3V-5.5V supply range, the device operates directly from a 12V automotive rail after regulation, simplifying the power tree.

Battery-Powered IoT Sensor Nodes
The XLP nanoWatt technology in the PIC16F15375 delivers sleep currents below 1 uA, making it an excellent choice for battery or energy-harvesting IoT endpoints that must run for years on a coin cell. The internal 32MHz HFINTOSC eliminates external crystal cost in compact PCB layouts, while the four PWMs and CWG can drive sensor excitation or LED indicator pulses directly. The 14KB Flash accommodates over-the-air (OTA) bootloader plus application code for BLE/Zigbee co-processor designs. When paired with a sub-GHz or BLE radio, the system can wake periodically, sample a 10-bit ADC channel, transmit, and return to deep sleep with minimal firmware complexity.

Industrial Control & Sensor Signal Conditioning
Industrial process controllers benefit from the PIC16F15375's 10-bit ADC with hardware computation, two comparators, and a 5-bit DAC that together implement closed-loop PID and limit-comparator functions entirely in hardware. The Core Independent Peripherals (CIPs) like the Configurable Logic Cell (CLC) and Numerically Controlled Oscillator (NCO) generate precise timing signals without CPU intervention, allowing deterministic response times below 1 microsecond. With 38 I/O pins, the device can interface to multiple 4-20mA loops, opto-isolated inputs, and relay outputs in a single chip. The 32MHz CPU bandwidth and 1KB SRAM comfortably handle Modbus RTU stacks over EUSART.
推薦
LED Lighting & Backlight Controllers
The PIC16F15375-E/MVVAO combines four 10-bit PWM channels with a Complementary Waveform Generator (CWG), making it ideal for driving multi-channel LED lighting controllers in architectural, automotive, and signage applications. The CWG can produce phase-shifted complementary PWMs to drive half-bridge or full-bridge FET stages without CPU overhead, enabling efficient buck or boost LED drivers with programmable dead-time. The 32MHz instruction rate supports smooth 16-bit PWM dimming via dithering, while the XLP sleep modes reduce standby power to nanoampere levels. The device can also run DMX512 or DALI receive stacks in 1KB SRAM with code reuse on the 14KB Flash.
推薦
HVAC & Climate Control Subsystems
HVAC damper motors, fan-speed controllers, and temperature regulators benefit from the PIC16F15375's mix of analog and digital peripherals. Two onboard comparators combined with the 10-bit ADC and 5-bit DAC enable multi-zone temperature feedback loops with hardware-accelerated hysteresis. The CWG drives triac-gate or FET-bridge circuits for AC fan control, while the four PWMs modulate brushless DC fans in variable-speed stages. AEC-Q100 qualification allows deployment in commercial vehicle HVAC modules where -40C cold-start and +125C under-hood exposure are mandatory operating conditions.

Medical Monitoring Accessories
Battery-powered medical accessories such as portable pulse oximeters, glucose meters, and wearable health patches can leverage the PIC16F15375's XLP architecture for multi-day operation on a single coin cell. The 10-bit ADC with hardware averaging reads photodiode or bio-impedance sensors with adequate resolution for trend monitoring, while the 14KB Flash supports USB-CDC or BLE bootloader plus application code. The two EUSART peripherals enable simultaneous sensor module communication and host UART bridging. AEC-Q100 stress-test pedigree is a valuable trust signal even outside automotive, indicating robust manufacturing and characterization.
推薦
Consumer Appliance Control Boards
White goods such as washing machines, dishwashers, and coffee makers benefit from the PIC16F15375's combination of 38 I/O pins, multiple PWMs, and dual EUSART interfaces that drive motor inverters, user-interface keypads, and LCD display modules concurrently. The 32MHz instruction throughput executes sensor-fusion algorithms for load-balancing and water-level detection in real time. With 1KB SRAM, a small RTOS kernel or preemptive scheduler fits comfortably, while the 14KB Flash stores GUI assets and lookup tables. The internal HFINTOSC removes crystal cost for cost-sensitive consumer price points.

設計說明
Estimated: The UQFN-40 5x5mm package has an exposed thermal pad (EP) on the underside that MUST be soldered to a copper pour for both thermal dissipation and electrical grounding. Design the PCB land pattern per IPC-7351 with at least 8 thermal vias (0.3mm drill, 0.5mm pitch) connecting the EP to internal ground planes. Without proper EP soldering, junction-to-ambient thermal resistance (theta_JA) can exceed 60 C/W, causing thermal shutdown under sustained 32MHz operation in high ambient temperatures.
Decouple VDD with a 100nF ceramic capacitor placed within 3mm of each VDD pin, plus a bulk 1uF to 10uF tantalum or ceramic on the main supply rail. For automotive 12V applications, use an MCP1754 or equivalent wide-input LDO upstream of the MCU. Brown-out detection (BOR) should be enabled in configuration bits to force a clean reset when VDD dips below 2.0V, preventing flash corruption during cranking transients. Configure the Power-on Reset timer for a minimum 64ms delay.
Do not confuse the /MV package suffix with Microchip's TQFP or QFN alternatives - the PIC16F15375-E/MVVAO is uniquely the 40-pin UQFN. When migrating code between PIC16F1535x and PIC16F1537x family members, verify that Peripheral Pin Select (PPS) mappings are reconfigured because PPS register assignments differ across pin counts. Finally, ensure the watchdog timer (WDT) is enabled in safety-critical automotive firmware to recover from software lockups within 2ms.
For SPI or EUSART signals running above 5 MHz, add 33 ohm series-termination resistors at the MCU pins to dampen transmission-line reflections on traces longer than 25mm. Keep ADC reference and analog signals routed away from PWM and CWG switching outputs on separate PCB layers with ground isolation. The CWG outputs can produce dV/dt rates exceeding 1V/ns; route these traces with at least 3x trace-width clearance to adjacent signals to minimize crosstalk into sensitive analog channels.
