Microchip PIC16LF1933T-I/ML: Low-Power 8-Bit Microcontroller for Embedded Control Applications

The Microchip PIC16LF1933T-I/ML is a high-performance, low-power 8-bit microcontroller designed for a wide range of embedded control applications. Built on Microchip's enhanced mid-range core, this MCU offers a compelling blend of processing capability, energy efficiency, and peripheral integration, making it an ideal solution for battery-powered and space-constrained designs.

A key strength of this microcontroller is its ultra-low power consumption. Operating with Microchip's eXtreme Low-Power (XLP) technology, the device is engineered to minimize current draw in all modes of operation. It features a deep sleep current that can be as low as 20 nA, making it exceptionally suited for applications that demand long battery life, such as remote sensors, medical devices, and portable instruments.

Despite its compact form factor in a 28-pin QFN (ML) package, the PIC16LF1933 is packed with robust features. It is powered by an enhanced Harvard architecture CPU with a 14-bit wide instruction set, providing efficient code execution and a flexible 8-level deep hardware stack. The device includes 7 KB of Flash program memory and 256 bytes of RAM, supported by a highly sophisticated peripheral set. This includes multiple communication interfaces like EUSART, I2C, and SPI for seamless connectivity, a Capture/Compare/PWM (CCP) module, and a dedicated 10-bit Analog-to-Digital Converter (ADC) with up to 11 channels for precise sensor data acquisition.

Furthermore, it integrates hardware features such as mTouch capacitive sensing technology for implementing touch interfaces without external components, and enhanced timer modules for complex control loop management. Its wide operating voltage range from 1.8V to 3.6V further enhances its suitability for low-voltage, battery-operated environments.
