MCHPPIC18F27Q43-I/SO
Overview
The PIC18F27Q43-I/SO is a high-performance 8-bit microcontroller from Microchip's PIC18-Q43 family, specifically designed with Functional Safety (FuSa) features for mission-critical applications. Operating at 64MHz, it integrates 128KB of Flash, 8KB of RAM, and a wide array of Core Independent Peripherals (CIPs) that offload timing-critical and logic functions from the CPU.
Why Choose This Part
This MCU offers a massive 128KB Flash in a 28-pin SOIC package, providing significant headroom for complex firmware in space-constrained designs. Its Core Independent Peripherals allow for lower power consumption and faster response times by handling signal processing and logic tasks in hardware.
Applications
Key Specifications
Getting Started
Development is supported by the MPLAB X IDE and the XC8 C Compiler, with the MPLAB Code Configurator (MCC) available for rapid peripheral setup. For hardware evaluation, the PIC18F57Q43 Curiosity Nano Evaluation Kit provides a compatible debugging platform for the Q43 family.
