Microchip PIC16LF19186T-I/PT: Low-Power 8-Bit Microcontroller for Embedded Systems

The Microchip PIC16LF19186T-I/PT is a highly integrated 8-bit microcontroller designed for embedded systems where ultra-low power consumption and robust peripheral integration are paramount. As part of Microchip’s enhanced mid-range PIC16F family, this MCU leverages the powerful PIC® core with a 16-level deep hardware stack and 49 instructions. Operating at a maximum frequency of 32 MHz, it delivers a performance of up to 8 MIPS while maintaining exceptional energy efficiency, making it ideal for battery-powered and portable applications.

A key strength of the PIC16LF19186T-I/PT is its extensive peripheral set, which minimizes external component count and simplifies design. It features multiple communication interfaces including EUSART, I²C, and SPI modules, enabling seamless connectivity with sensors, displays, and other ICs. The inclusion of multiple PWM outputs, a 10-bit ADC with up to 35 channels, and complementary waveform generators (CWG) provides precise control for motor drive and power management applications.

The device is built with nanoWatt XLP technology, which drastically reduces power consumption during active and sleep modes. This allows the microcontroller to operate at currents as low as 30 µA/MHz in active mode and 20 nA in deep sleep mode (with RAM retention), significantly extending battery life in always-on or intermittently active systems.

Housed in a 44-pin TQFP package, the PIC16LF19186T-I/PT offers ample I/O flexibility with 36 programmable pins. It includes 56 KB of Flash program memory and 4 KB of RAM, providing sufficient resources for complex embedded applications. Additional features such as Memory Access Partition (MAP) and a Hardware Limit Timer (HLT) enhance system security and reliability by isolating code and preventing software lock-ups.

ICGOODFIND: This microcontroller stands out for its combination of ultra-low power operation, high integration of advanced analog and digital peripherals, and strong security features—making it a superior choice for developers of power-sensitive embedded systems in consumer, industrial, and medical markets.
