PIC16F1575T-I/SL 概要
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash/ROM), working memory (RAM), and programmable I/O peripherals. The PIC16F family uses Microchip's enhanced mid-range 8-bit RISC architecture with a 14-bit instruction word, balancing deterministic execution, low power consumption, and ease of use. PIC microcontrollers sit within the broader taxonomy: microcontroller -> embedded processor -> semiconductor -> integrated circuit. The PIC16F1575 belongs to the PIC16(L)F157x sub-family, distinguished by 16-bit PWM peripherals for fine-grained control of LED lighting, motor drives, and power conversion.
Key features include four independent 16-bit PWM channels (16-bit resolution versus the typical 10-bit PWM of competing MCUs), a 10-bit ADC with up to 12 channels, two comparators, one 5-bit DAC, CWG for dead-band control in half-bridge and full-bridge topologies, PPS for flexible pin assignment, and EUSART supporting LIN and RS-232. The wide 2.3V to 5.5V operating range (PIC16F variant, 'F' = standard voltage) covers 3.3V and 5V rails common in industrial and consumer designs. The industrial temperature grade -40C to +85C suits most indoor and protected outdoor environments.
Architecturally, the PIC16F1575 uses a Harvard bus with separate program and data paths, 49 instructions, and a hardware stack depth of 16. The 32MHz internal oscillator eliminates external crystals in cost-sensitive designs. CoreMark performance is sufficient for sensor fusion, lighting protocols, and simple UI loops, while CWG plus 16-bit PWM enable direct generation of phase-shifted gate-drive waveforms without an external gate-driver IC in many cases.
Typical applications include LED lighting drivers (constant-current RGBW and dim-to-warm), complementary half-bridge motor control for low-voltage BLDC fans, digital power-supply housekeeping loops, battery charging management for 1-2S Li-Ion packs, and general-purpose sensor hubs with PWM-driven haptic feedback. The four 16-bit PWMs also simplify sensorless BLDC commutation when combined with zero-cross detection from the on-chip comparators.
When designing with this MCU, allocate at least one PWM channel as the system tick or for a status LED to confirm firmware boot. The PPS remapping feature simplifies PCB routing but requires careful attention to digital-isolator and boot-loader pin assignments - not every peripheral output can be routed to every I/O.

主な用途
PIC16F1575T-I/SL の用途: 6 件s: LED Lighting Controllers (RGBW/Dim-to-Warm), BLDC Fan / Low-Voltage Motor Control, Digital Power Supply Housekeeping, Battery Charging Management (1-2S Li-Ion), Haptic Feedback and Sensor Hubs, General Purpose Mixed-Signal Control.
LED Lighting Controllers (RGBW/Dim-to-Warm)
The PIC16F1575T-I/SL's four independent 16-bit PWM channels deliver 65536-step resolution per channel, supporting smooth logarithmic dimming curves required for high-end architectural and stage lighting. According to the datasheet, each PWM has its own timer, eliminating software jitter when driving RGBW constant-current LED drivers such as the AL8860 or LM3409. The on-chip CWG generates phase-shifted gate drive for half-bridge and full-bridge LED topologies, while the 5-bit DAC and comparators handle analog dim-to-warm color-temperature feedback. Compared with 10-bit PWM MCUs, the 16-bit PWM enables sub-1 LSB dimming at low brightness, eliminating visible flicker in dim-to-off transitions common in residential lighting.

BLDC Fan / Low-Voltage Motor Control
The PIC16F1575T-I/SL drives sensored and sensorless BLDC fans up to several hundred mA by combining three of its 16-bit PWMs with the Complementary Waveform Generator (CWG). CWG inserts programmable dead-time (in 4-bit increments) to prevent shoot-through in half-bridge MOSFET pairs, while the on-chip comparators sense back-EMF zero crossings for sensorless commutation. At 32 MHz the MCU computes next-cycle timing in under 1 us, well inside the 10-100 us electrical period of small fans. The wide 2.3V to 5.5V supply allows direct battery connection in 1S Li-Ion or 2-3 AA packs, while industrial -40C to +85C rating supports fan-tray and appliance use.
おすすめ
Digital Power Supply Housekeeping
The PIC16F1575T-I/SL acts as a housekeeping MCU in isolated DC-DC converters, supervising enable sequencing, fault monitoring, and PMBus/I2C telemetry. Its 10-bit ADC samples output voltage and current sense at up to 100 ksps, while the 16-bit PWMs generate synchronous rectifier timing signals or auxiliary rails. The EUSART port handles UART-based firmware upgrades without external boot loader circuitry. Compared with fixed-function housekeeping ASICs, this MCU offers firmware-definable OV/UV/OC thresholds and supports field firmware updates via I2C. The PPS peripheral reassigns comparator and PWM outputs to different pins, simplifying PCB layout in dense quarter-brick modules.
おすすめ
Battery Charging Management (1-2S Li-Ion)
The PIC16F1575T-I/SL implements CC/CV charging algorithms for 1S or 2S Li-Ion packs by combining ADC current sensing, PWM-controlled buck converter duty cycle, and EUSART status reporting. Its 2.3V to 5.5V supply accommodates direct USB 5V input, and the 16-bit PWM enables fine current-resolution steps (sub-mA) during the constant-voltage tail. The 14-pin SOIC package fits inside the cable end of a USB-C charger dongle, and the on-chip comparators terminate charge on full-current slope change. Compared with dedicated charger ICs, this MCU adds programmable chemistry profiles, NTC thermistor monitoring, and field firmware updates.
おすすめ
Haptic Feedback and Sensor Hubs
The PIC16F1575T-I/SL serves as a sensor-hub MCU in wearables and IoT peripherals, using its ADC to read accelerometers, hall sensors, or capacitive touch, and its 16-bit PWMs to drive LRA/ERM haptic actuators. PWM resolution is critical here: a 16-bit PWM at 32 MHz can generate 200 kHz LRA drive signals with 250-step amplitude control, exceeding the typical 10-bit PWM resolution. The CWG generates complementary drive with dead-band, eliminating the external gate-driver IC. PPS allows the same firmware to route PWM to different actuator pins across SKUs, reducing BOM variants.
おすすめ
General Purpose Mixed-Signal Control
The PIC16F1575T-I/SL is well-suited as a general-purpose mixed-signal controller for industrial sensor nodes, low-end HMI, and appliance control. It combines 10-bit ADC for analog sensor readout, two comparators for window-detection, 5-bit DAC for analog set-point output, EUSART for RS-232/LIN communication, and PPS for flexible PCB routing. The 14-pin SOIC footprint balances GPIO count with board area, fitting in 50 mm x 30 mm sensor modules. At 32 MHz and 8 MIPS, the MCU executes 100 kS/s control loops with overhead for UART command processing and LED status indication.

設計ノート
The PIC16F1575T-I/SL draws up to approximately 8 mA active at 32 MHz and 5 V (verify against the datasheet's DC characteristics table). Place a 100 nF decoupling capacitor within 3 mm of VDD (pin 1) and a bulk 1-10 uF capacitor on the same rail. The internal 32 MHz HFINTOSC eliminates the need for an external crystal in most cost-sensitive designs, but adds 1-2% frequency error versus an external crystal - acceptable for PWM timing but unsuitable for UART at high baud rates.
Pin 4 (MCLR/VPP) must be tied to VDD through a 10 kohm pull-up resistor for normal operation; floating MCLR causes erratic resets. When using ICSP (In-Circuit Serial Programming), connect a resistor (typically 4.7 kohm) on ICSPCLK/ICSPDAT (RB6/RB7) to prevent programming contention. The 16-bit PWM timers are clocked from Fosc/4 = 8 MHz at 32 MHz CPU; do not assume the default PWM frequency - it is set by the PR2/PR4 registers and can range from 122 Hz to 32 MHz.
Route analog inputs (RA0-RA5 when configured as ADC) away from PWM outputs to minimize digital coupling into ADC samples. The PIC16F1575 datasheet recommends a ground plane under the SOIC footprint to reduce digital switching noise on ADC readings; for 10-bit ADC accuracy this is generally sufficient. PPS-routed signals should be confirmed against the device-specific PPS table - not every peripheral can map to every pin.
