Microchip PIC16LF1847-I/SO 8-Bit Microcontroller: Features and Applications
The Microchip PIC16LF1847-I/SO is a high-performance, low-power 8-bit microcontroller built on Microchip’s enhanced mid-range core. This powerful yet efficient MCU is designed for a wide range of embedded control applications, offering a compelling blend of advanced peripherals, robust processing capabilities, and exceptional energy efficiency, all packaged in a compact 20-pin SOIC (SO) package.
Key Features
At the heart of the PIC16LF1847 lies the enhanced mid-range core with a 16-level deep hardware stack and a 49-instruction set. Operating at up to 32 MHz, it delivers a performance of 8 MIPS. A standout feature is its extremely low power consumption (nanoWatt XLP Technology), making it ideal for battery-powered and energy-harvesting applications where extending battery life is critical.
The microcontroller is equipped with a rich set of integrated peripherals:
mTouch Capacitive Sensing (CPS) Module: Allows for the implementation of touch interfaces (buttons, sliders, proximity sensors) without external components.
Enhanced Universal Synchronous Asynchronous Receiver Transmitter (EUSART): Supports both LIN and DMX protocols, ideal for serial communication and lighting control.
Two Capture/Compare/PWM (CCP) modules and one Enhanced CCP (ECCP) with pulse steering, perfect for precise motor control and power conversion.
7-channel 10-bit Analog-to-Digital Converter (ADC) with hardware Capacitor Voltage Divider (CVD) support for advanced touch sensing and analog signal acquisition.
Two Configurable Logic Cells (CLCs): These allow for the creation of custom combinational and sequential logic functions directly in hardware, offloading the CPU and enabling interface glue logic without external chips.
5-bit Digital-to-Analog Converter (DAC) and two comparators for analog signal conditioning.
It also boasts 14 KB of self-read/write Flash program memory and 512 bytes of RAM, providing ample space for application code and data handling.
Primary Applications
The combination of its features makes the PIC16LF1847-I/SO exceptionally versatile. Its primary applications include:
Consumer Electronics: Remote controls, touch-activated panels, toys, and small appliances.
Automotive: Interior lighting control, small motor control (e.g., fans, window lift), and sensor interfaces.
Industrial Control: Sensor nodes, actuators, button panels, and simple programmable logic controllers (PLCs).
Internet of Things (IoT) End Nodes: Battery-operated wireless sensors, data loggers, and other devices where ultra-low power is a prerequisite.
Lighting Control: LED dimming and color control using its PWM and communication peripherals.
The Microchip PIC16LF1847-I/SO is a highly integrated and power-efficient solution for designers. Its unique combination of nanoWatt XLP technology, hardware touch sensing, and configurable logic cells provides a significant competitive advantage, reducing system component count, power consumption, and development time for a vast array of modern embedded designs.
