R7FA6M3AH3CFC#AA0 Product Overview
The R7FA6M3AH3CFC#AA0 is a high-performance 32-bit microcontroller from Renesas RA6M3 series, built on the ARM Cortex-M4F core with integrated Floating Point Unit (FPU) and operating at up to 120MHz. Housed in an LFQFP-176 (24×24mm, 0.5mm pitch) package, it operates from 2.7V to 3.6V with an industrial temperature range of -40℃ to +105℃. The device integrates 2MB Code Flash, 640KB SRAM, and 64KB Data Flash (for EEPROM-like data storage), along with a graphics LCD controller (with 2D drawing engine and JPEG decoder), capacitive touch sensing unit, Ethernet MAC controller (with dedicated DMA), USB 2.0 High-Speed and Full-Speed interfaces, and comprehensive security features. With large memory, powerful graphics processing capability, and comprehensive connectivity, the R7FA6M3AH3CFC#AA0 provides a high-performance embedded solution for industrial automation, IoT gateways, HMI, and smart home appliances.
