Microchip PIC16F18425-I/JQ 8-Bit Microcontroller Overview and Application Guide

The Microchip PIC16F18425-I/JQ is a versatile 8-bit microcontroller from Microchip Technology’s enhanced mid-range PIC® MCU family. Built around a high-performance RISC CPU, this device integrates a rich set of peripherals, making it an ideal solution for a wide array of embedded control applications in consumer, industrial, automotive, and Internet of Things (IoT) domains.

Housed in a compact 20-pin UQFN package, the PIC16F18425 features enhanced Core Independent Peripherals (CIPs) that minimize CPU intervention and boost system efficiency. Key among these are multiple Configurable Logic Cells (CLCs), which allow designers to implement custom logic functions directly in hardware, and a Complementary Waveform Generator (CWG) for advanced motor control and power conversion applications.

The microcontroller operates at up to 32 MHz and includes 16 KB of Flash program memory and 512 bytes of RAM. It is further supported by 256 bytes of high-endurance EEPROM for data storage. A standout feature is its advanced analog capability, incorporating a 10-bit Analog-to-Digital Converter (ADC) with up to 17 channels and two 5-bit Digital-to-Analog Converters (DACs). These features make it exceptionally suited for precision sensing and signal conditioning tasks.

Communication is facilitated through multiple serial interfaces, including EUSART (for LIN compatible communication), SPI, and I²C, providing flexible connectivity options. The inclusion of mTouch® capacitive sensing hardware allows for the easy implementation of touch interfaces without external components.

With its wide operating voltage range (1.8V to 5.5V) and nanoWatt XLP technology, the device is engineered for ultra-low-power operation, which is critical for battery-powered and energy-harvesting applications. Its robust design and integrated features help reduce system component count, lower overall cost, and accelerate time to market.

ICGOODFIND: The PIC16F18425-I/JQ stands out as a highly integrated, low-power 8-bit MCU. Its combination of core-independent peripherals, advanced analog, and hardware-based touch sensing makes it a powerful and flexible choice for designers optimizing for performance, power, and cost in space-constrained embedded systems.
