PIC16F1575-E/ST 개요
An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path that integrates a CPU, non-volatile program memory, working RAM, and on-chip peripherals. The PIC16F1575 belongs to the Microchip mid-range 8-bit MCU family, which sits in the broader hierarchy of microcontrollers -> embedded processors -> semiconductors -> integrated circuits. Mid-range 8-bit cores are favored for deterministic real-time control where predictable instruction timing matters more than raw compute throughput.
Key features include four independent 16-bit PWMs with hardware triggering for LED dimming and motor control, peripheral pin select (PPS) for flexible signal routing, a 10-bit ADC with internal voltage reference, and a 5-bit DAC for analog set-point generation. The complementary waveform generator produces complementary drive signals with programmable dead-band, which simplifies half-bridge and full-bridge switching stages.
Architecturally the device uses a 14-bit instruction word RISC core running up to 32 MHz, with an instruction fetch pipeline that delivers most instructions in one cycle. The 16-bit PWM modules derive their time base from Fosc/4 or an external source, providing 16 ns resolution at 32 MHz and supporting center-aligned, edge-aligned, and variable-phase modes.
Typical applications include LED lighting dimming and color mixing, switched-mode power supply control, battery charging, small motor control (BLDC, stepper, and brushed DC), and sensor signal conditioning. The integrated CWG and comparators support peak current mode control without an external PWM controller.
When designing with this part, allocate the 14-pin budget carefully: VDD, VSS, MCLR, and programming/debug pins (ICSPCLK/ICSPDAT) consume four, leaving ten GPIOs. PPS remaps most digital peripherals so any digital function can land on most pins, easing PCB layout.

일반적인 애플리케이션
PIC16F1575-E/ST 적합 용도: 6 애플리케이션s: High-Resolution LED Lighting Dimming, Switched-Mode Power Supply (SMPS) Control, Small Motor Control (BLDC, Stepper, Brushed DC), Battery Charging and Power Bank Management, Sensor Signal Conditioning and Industrial Sensing, Smart Home and IoT Edge Nodes.
High-Resolution LED Lighting Dimming
The PIC16F1575-E/ST's four hardware 16-bit PWM channels deliver sub-microsecond dimming resolution at 32 MHz, eliminating the low-frequency flicker perceivable at 8-bit PWM (200 Hz+ at 1 MHz time base). In a typical 4-channel RGBW fixture the MCU drives each LED string with center-aligned PWM and a phase shift to spread the switching load, while the 5-bit DAC sets a programmable current reference. The CWG can be combined with the comparators to build constant-current hysteretic control without external op-amps, reducing BOM cost and PCB area versus discrete PWM-LED driver ICs. At full 14KB Flash, a complete DALI or DMX-512 firmware stack plus color-temperature LUT fits comfortably.

Switched-Mode Power Supply (SMPS) Control
In a digital SMPS the PIC16F1575-E/ST acts as the primary controller, with its 10-bit ADC sampling the output voltage and a 16-bit PWM driving the power MOSFET gate. The two on-chip comparators support peak current-mode control with cycle-by-cycle current limiting, while the CWG produces complementary gate drive with programmable dead-band for half-bridge and active-clamp topologies. At 32 MHz the 16-bit PWM delivers 1.95 kHz step resolution at a 125 kHz switching frequency, sufficient for tight regulation loops. The 14-pin TSSOP footprint and 2.3V minimum VDD also enable battery-input flyback converters and tiny PoE auxiliary rails.

Small Motor Control (BLDC, Stepper, Brushed DC)
The PIC16F1575-E/ST drives small brushless DC motors and stepper motors in tools, fans, and small appliances. Its four 16-bit PWMs can be paired as complementary outputs through the CWG to drive a 3-phase inverter with dead-band insertion, while the 10-bit ADC reads back-link BEMF zero-crossing signals through two on-chip comparators for sensorless trapezoidal commutation. Center-aligned PWM mode keeps current ripple symmetric, reducing audible torque ripple. At 32 MHz instruction rate, a 6-step trapezoidal algorithm runs with sub-10us latency, comfortably within the 50us commutation interval at typical 20 krpm speeds.

Battery Charging and Power Bank Management
In Li-ion and LiFePO4 chargers, the PIC16F1575-E/ST monitors battery voltage via the 10-bit ADC, regulates charge current through the 5-bit DAC, and generates PWM gate drive for a synchronous buck converter. The internal 31 kHz low-power oscillator supports sleep-mode current sensing at <1 uA, important for standby power budgets in always-on chargers. The extended -40C to +125C temperature grade lets the same firmware serve both indoor and outdoor charging cabinets. PPS makes the SMBus / I2C-like comms available on any GPIO, simplifying PCB routing in space-constrained power banks.

Sensor Signal Conditioning and Industrial Sensing
In industrial 4-20 mA loop-powered sensors, the PIC16F1575-E/ST digitizes analog inputs from bridge sensors or thermocouples using the 10-bit ADC, applies linearization in firmware, and transmits via the EUSART in HART or RS-485 formats. The wide 2.3 to 5.5 V VDD lets it run directly from a 24V loop through a series regulator. The internal comparator enables window-comparator overrange detection without firmware overhead, while PPS remaps the EUSART and PWM to free up the analog pins. The extended -40C to +125C temperature grade and 14-pin TSSOP suit DIN-rail-mounted sensor heads.

Smart Home and IoT Edge Nodes
In Zigbee/BLE actuator nodes and smart thermostats, the PIC16F1575-E/ST functions as the analog front-end MCU alongside a radio co-processor. The 16-bit PWMs drive triac phase-control dimmers and motorized valves, the 10-bit ADC reads thermistor or humidity sensors, and the EUSART serves as the host interface to the radio. PPS permits the EUSART to be relocated if the PCB routing requires it, and the internal HF oscillator at 16 MHz removes an external crystal, saving two pins and BOM cost. At deep sleep the device draws microamps thanks to the 31 kHz LF oscillator and PIC16 nanoWatt XLP technology.

설계 노트
Estimated: VDD decoupling - place a 100 nF ceramic capacitor as close as possible to the VDD/VSS pins (pin 4 and pin 5) with the loop area under 5 mm^2. For PWM-heavy applications also add a 10 uF bulk tantalum or ceramic on VDD. The internal HF oscillator pulls <5 mA switching current at 32 MHz; insufficient bulk capacitance causes digital noise on the analog channels during heavy PWM transitions.
On a 14-pin TSSOP, the dual-purpose ICSPCLK/ICSPDAT pins (RB6/RB7) must remain accessible for in-circuit serial programming. Reserve a 6-pin (0.1 inch pitch) header footprint on the PCB that taps VDD, VSS, MCLR, RB6, RB7, and one GPIO. Avoid running high-current switching traces under the ICSP header to prevent programming glitches.
For sensitive analog measurements, route the analog inputs (AN0-AN4) away from the CWG output traces. If a CWG output and an analog input must be near, place a ground trace between them. Enable the peripheral pin select (PPS) to remap digital functions to non-adjacent pins when layout forces close analog/digital proximity. Use the digital-to-analog crosstalk specification in the datasheet electrical characteristics section as a sanity check.
Do not leave MCLR floating - always tie MCLR to VDD through a 10 kohm pull-up, and add a 100 nF cap to ground for ESD/spike rejection. When using the internal HF oscillator, the OSCCON register must be configured correctly after power-up; relying on the default HFINTOSC selection can cause unexpected startup behavior. For sleep-mode designs, verify the secondary oscillator (SOSC) is enabled via OSCEN before using the 31 kHz LF source.
