PIC16F1579T-I/SO

Microcontrollers Overview

The PIC16F1579T-I/SO is an 8-bit microcontroller from the PIC16(L)F157x family, manufactured by Microchip Technology. It features a PIC16 core with up to 14 KB of Flash program memory and 1024 bytes of data SRAM. The device supports operating speeds up to 32 MHz with a minimum instruction cycle of 125 ns. It includes four 16-bit PWMs, two comparators, a 10-bit ADC with up to 12 channels, and a 5-bit DAC. The unit operates within a voltage range of 2.3V to 5.5V and functions in industrial temperatures from -40°C to 85°C. It is housed in a 20-pin SOIC package.

Microcontrollers Feature Summary

• Integrates four independent 16-bit Pulse-Width Modulation modules for high-resolution control applications.
• Includes Peripheral Pin Select (PPS) functionality allowing flexible remapping of digital peripheral I/O pins.
• Features an Enhanced Universal Synchronous Asynchronous Receiver Transceiver (EUSART) supporting LIN communication protocols.
• Provides Complementary Waveform Generator (CWG) with dead-band control for motor drive applications.

Microcontrollers Applications

• LED lighting systems requiring high-resolution dimming
• Stepper motor control circuits
• Power supply management units
• General purpose embedded applications

Microcontrollers Procurement Notes

Verify the specific ordering suffix 'T' indicates tape and reel packaging rather than tube packaging when placing orders. Confirm the 'I' suffix corresponds to the industrial temperature range (-40°C to 85°C). Ensure the 'SO' designation matches the required 20-pin SOIC footprint for PCB layout compatibility. Cross-reference the full part number against the manufacturer's current datasheet revision to confirm active status and any potential pinout changes.

Microcontrollers Selection Notes

Select this component when high-resolution pulse-width modulation is required alongside analog signal processing capabilities. The inclusion of PPS allows for optimized board routing by decoupling peripheral functions from fixed pin assignments. Consider the 16-level hardware stack for complex interrupt handling scenarios. Evaluate the low-power sleep modes if battery operation is a constraint within the specified voltage range.

Microcontrollers Part Context

This device belongs to the PIC16(L)F1574/5/8/9 series, which combines 16-bit PWM capabilities with analog peripherals. It utilizes the Enhanced Mid-Range CPU architecture, offering a C compiler-optimized RISC instruction set. The series is designed for applications demanding precise timing and feedback control, distinguishing it from standard 8-bit PWM variants through its independent timer structures.
