PIC16F1579-I/P - 32MHz 8-Bit MCU with PWM | Microchip
MPN: PIC16F1579-I/P ✓ نشطPIC16F1579-I/P نظرة عامة
A microcontroller is a programmable integrated circuit containing a processor core, program memory, data memory, and peripherals. The PIC16 core belongs to Microchip's PIC16 family of embedded controllers, where each device executes firmware for control, measurement, communications, and automation tasks. Unlike a general-purpose computer, this MCU is configured around a small pin count, dedicated analog and timing peripherals, and low-power embedded operation.
Four 16-bit PWM channels with independent timers support high-resolution motor, dimming, and power-control functions. The 10-bit ADC adds 1,024 possible quantization levels for analog measurement, while the 5-bit DAC provides a compact output for control or reference signals. The industrial-temperature grade and 20-PDIP through-hole package make the device suitable for designs assembled with conventional through-hole insertion.
The 32 MHz PIC16 CPU core provides faster instruction execution than earlier 8-bit PIC16 designs, while 8K words of Flash program storage accommodate application code and configuration data. The architecture integrates timing, digital I/O, and analog conversion functions on one device, reducing the component count in applications that require multiple 16-bit waveform channels or mixed analog and digital control.
Typical uses include LED lighting controllers, DC motor and stepper positioning systems, industrial instrumentation, environmental monitoring, compact power converters, and educational embedded-control platforms. The combination of four PWM channels, analog conversion, and a 5-bit DAC is particularly useful when a controller must measure an analog input and drive one or more precise timing outputs.
When laying out the board, use the pin-description and electrical-characteristics tables in the manufacturer datasheet to assign each 20-pin DIP position. Keep analog inputs and the DAC output away from high-current switching paths, provide the specified decoupling near the supply pins, and route programming and reset signals for reliable operation.
This product page combines the manufacturer device capabilities with practical selection guidance, verified sourcing links, application-specific design reasoning, and transparent notes on package, compliance, and replacement constraints for engineers evaluating the PIC16F1579-I/P.

التطبيقات النموذجية
PIC16F1579-I/P مناسب لـ 6 التطبيقs: LED Lighting and Dimming Control, DC Motor Speed Regulation, Analog Process Instrumentation, Environmental Monitoring Node, Compact Power Converter Control, Educational Embedded-Control Platform.
LED Lighting and Dimming Control
The PIC16F1579-I/P fits LED lighting controllers because its four independent 16-bit PWM channels can generate precise duty cycles for multiple lighting channels or complementary drive signals. According to the Microchip Technology device page, high-resolution PWM is specifically suited to LED lighting applications. The 32 MHz core can update dimming levels and respond to current or environmental feedback while the 10-bit ADC monitors analog sensor inputs. Use the independent timers to coordinate several channels, then drive LEDs through a suitable external transistor or constant-current stage because the MCU pins are control outputs, not direct power drivers.

DC Motor Speed Regulation
The PIC16F1579-I/P can implement a closed-loop DC motor controller using one PWM channel for the drive command and the 10-bit ADC for speed or current feedback. Its 32 MHz execution rate supports frequent control-loop updates, while four independent 16-bit PWM channels provide flexible timing for drive, braking, or auxiliary outputs. The industrial temperature grade is useful in equipment where temperature varies around the controller. Design the power stage separately, add appropriate protection, and validate that motor current and switching transients remain outside the MCU supply and I/O limits.
موصى به
Analog Process Instrumentation
The PIC16F1579-I/P is suitable for compact process instrumentation because it combines a 10-bit ADC, comparator, 5-bit DAC, and 32 MHz control core in one device. The ADC supports analog measurement, the comparator can provide fast threshold events, and the DAC can generate a basic control or reference output. Firmware can sample the selected analog channel, apply filtering and calibration, and present results through digital I/O or another communications peripheral. Keep sensitive analog routing away from PWM outputs and switching nodes, and follow the manufacturer layout recommendations for grounding and decoupling.
موصى به
Environmental Monitoring Node
The PIC16F1579-I/P can serve as the control core of an environmental monitoring node that periodically measures an analog sensor and records the result. The 10-bit ADC handles sensor conditioning outputs, the 1 KB RAM supports temporary measurement data, and the 14 KB Flash capacity is sufficient for a focused acquisition and communications firmware. Low-power operating modes can help reduce energy use between samples, although the final duty cycle must be configured through the device's clock, peripheral, and timing controls. A through-hole package also supports prototype and industrial monitor-board assembly.
موصى به
Compact Power Converter Control
The PIC16F1579-I/P can supervise a compact switching power converter by using the 10-bit ADC to observe output voltage and current feedback while the comparator detects thresholds. The 32 MHz core supports timely supervisory logic, fault flags, and adjustment of a PWM-driven converter through an external power stage. Four independent timers allow the controller to separate switching, sampling, and protection timing functions. The implementation must include suitable compensation, isolation or level-shifting where required, and fault shutdown logic; software configuration alone is not a substitute for hardware protection.

Educational Embedded-Control Platform
The PIC16F1579-I/P works well in educational embedded-control platforms because it combines an approachable 8-bit RISC core with professional mixed-signal and timing peripherals. Students can use the four 16-bit PWM channels for motor or LED experiments, the 10-bit ADC for sensor exercises, the comparator for threshold demonstrations, and the 5-bit DAC for basic waveform output. Its 32 MHz operating speed provides responsive behavior while 14 KB of Flash and 1 KB of RAM support meaningful application code. The 20-pin PDIP footprint also makes it convenient to prototype on a breadboard or through-hole training board.

ملاحظات التصميم
Route analog inputs, comparator inputs, and the DAC output as sensitive nets, keeping them away from PWM outputs, external switching nodes, and high-current return paths. Place the required bypass capacitors at the device supply pins and provide a low-impedance ground connection. Use the package-specific pin-description and decoupling tables in the Microchip Technology datasheet because the 20-pin PDIP assigns analog, digital, and programming functions differently from other PIC16F1579 packages.
The four independent 16-bit timers should be assigned early in firmware because each PWM channel and its associated output pin constrain board-level assignments. Confirm whether the selected I/O pins are multiplexed with analog or comparator functions before finalizing the schematic. Keep programming and reset traces away from PWM edges and noisy analog inputs, and follow the manufacturer's configuration guidance for oscillator, reset, and brown-out functions to prevent unintended startup behavior.
Do not treat similar PIC16F1579 package suffixes as direct PCB substitutes: QFN, SOIC, and PDIP versions require different footprints and can expose different pin functions. Likewise, a generic 8-bit MCU with matching clock speed is not a drop-in replacement because peripheral registers, interrupts, ADC behavior, and PWM controls differ. Validate the exact -I/P ordering suffix, use the 20-pin PDIP pin table, and compile the production firmware against the correct device configuration before releasing the PCB.
معلومات الامتثال
The industrial temperature grade is identified for this device, but specific RoHS, REACH, lead-free, halogen-free, and conflict-minerals declarations are not confirmed by the available manufacturer and distributor information. AEC-Q100 is not applicable because this is a general-purpose industrial microcontroller rather than an automotive-qualified variant.
