Microchip PIC16LF1938-I/MV 8-Bit Microcontroller for Low-Power Embedded Applications
The demand for efficient, low-power microcontrollers continues to grow, driven by the proliferation of battery-operated and energy-sensitive devices. The Microchip PIC16LF1938-I/MV stands out as a robust 8-bit microcontroller engineered specifically to meet the stringent power requirements of modern embedded applications while delivering impressive computational performance.
At the core of this device is Microchip's enhanced mid-range PIC16 architecture, which operates at speeds up to 32 MHz, offering a compelling blend of processing power and energy efficiency. A key feature of the PIC16LF1938 is its nanowatt technology, which enables extremely low power consumption across multiple operational modes. This includes a deep sleep mode with currents as low as 20 nA, making it ideal for applications that spend significant time in a standby state, waking only periodically to perform tasks. This capability is critical for extending battery life in products like portable medical devices, remote sensors, and smart home automation systems.
The microcontroller is equipped with a rich set of peripherals integrated on a single chip, reducing system complexity and total component count. It features 28 KB of self-read/write Flash program memory and 1,024 bytes of data EEPROM, providing ample space for application code and critical data storage. Its versatile I/O portfolio includes 36 pins, multiple communication interfaces such as EUSART, I2C, and SPI, and two capture/compare/PWM (CCP) modules. Furthermore, it includes a 10-bit Analog-to-Digital Converter (ADC) with up to 17 channels, allowing for direct interfacing with a wide array of analog sensors.
The integrated mTouch capacitive sensing module is another standout feature, enabling the design of modern, button-free user interfaces with proximity and touch sensing capabilities. This is particularly valuable for consumer appliances and industrial control panels where reliability and aesthetics are paramount.
Housed in a compact 40-pin UQFN package, the PIC16LF1938-I/MV is designed for space-constrained applications. Its extended industrial temperature range (-40°C to +85°C) ensures reliable operation in harsh environments.
ICGOODFIND: The PIC16LF1938-I/MV is a highly integrated, ultra-low-power solution from Microchip, perfectly suited for developers creating power-sensitive embedded systems that require a rich set of features, robust performance, and long battery life.
