Microchip PIC16LF1934-I/PT: Low-Power 8-Bit Microcontroller for Embedded Systems

The Microchip PIC16LF1934-I/PT is a high-performance, low-power 8-bit microcontroller engineered for power-sensitive embedded applications. Built on Microchip’s enhanced mid-range core (nanoWatt XLP technology), this device delivers an optimal blend of processing performance, peripheral integration, and energy efficiency, making it a compelling choice for battery-operated and portable systems.

A defining trait of the PIC16LF1934 is its extremely low power consumption. Leveraging nanoWatt XLP technology, the microcontroller achieves deep sleep currents as low as 20 nA while maintaining RAM retention. This allows designs to achieve extended battery life, often lasting years on a single battery in applications such as remote sensors, medical devices, and smart meters.

Despite its compact 8-bit architecture, the PIC16LF1934 is equipped with a rich set of integrated peripherals that reduce system component count and total cost. It features a 12-channel 10-bit Analog-to-Digital Converter (ADC), multiple timers, two comparators, and EUSART/I²C/SPI communication modules. A standout capability is its mTouch capacitive sensing hardware support, enabling the design of robust and responsive touch interfaces without external components.

The device offers 14 KB of Flash program memory and 512 bytes of RAM, providing ample space for embedded control logic and data handling. Its operating voltage ranges from 1.8V to 3.6V, accommodating various low-voltage power sources. Housed in a 44-pin TQFP package, the PIC16LF1934-I/PT offers a compact footprint suitable for space-constrained PCB layouts.

Development is supported by Microchip’s MPLAB X IDE and the MPLAB Code Configurator (MCC), which streamline code development and peripheral initialization. These tools help developers quickly prototype and deploy applications, accelerating time to market.

ICGOODFIND: The PIC16LF1934-I/PT stands out as a versatile, ultra-low-power MCU ideal for developers designing connected, portable, or touch-based embedded systems where energy efficiency and integration are critical.
