Overview

The PIC16F18346-I/GZ is a versatile 8-bit microcontroller featuring 28KB of Flash memory and a rich set of Core Independent Peripherals (CIPs) for efficient real-time control. It includes 256 bytes of EEPROM and 2KB of RAM, operating at speeds up to 32MHz in a compact 20-pin UQFN package. This MCU is designed for low-power applications with flexible power-saving modes like IDLE and DOZE.

Why Choose This Part

This MCU offers a high degree of integration with 18 I/O pins in a small 4x4mm footprint, supporting a wide operating voltage range up to 5.5V. The inclusion of hardware DMA and CRC in an 8-bit device allows for sophisticated data handling and improved system reliability. Engineers benefit from the 16-level hardware stack and compiler-optimized architecture for efficient C development.

Applications

Industrial Sensor Nodes
Uses the integrated 10-bit ADC and 5-bit DAC for signal conditioning and monitoring in 5V industrial environments.
Communication Bridges
Utilizes dual SPI/I2C interfaces and UART to act as a protocol translator between legacy LINbus systems and modern sensors.
Battery-Powered Handhelds
Leverages low-current Sleep modes and an on-chip oscillator to extend battery life in portable electronics.
Peripheral Sequencing
Employs the built-in DMA and CRC modules to handle data movement and integrity checks without CPU intervention.

Getting Started

To begin development, use the Microchip MPLAB X IDE alongside the XC8 Compiler and the MPLAB Code Configurator (MCC) for rapid peripheral initialization. Hardware debugging and programming are supported by the MPLAB PICkit 4 or ICD 4 tools via the ICSP interface. For prototyping, the Curiosity Low Pin Count (LPC) Development Board is a compatible hardware platform.
