The Microchip Technology ATSAM3A4CA-AUR is a 32-bit RISC microcontroller featuring a Cortex-M3 CPU operating at up to 84MHz. This CMOS device offers 262KB of FLASH program memory and 65.5KB of data RAM. Connectivity options include dual CAN, dual I2C, I2S, SDMMC, SPI, three USARTs, and USB. On-chip peripherals include 21 DMA channels, a Real-Time Clock (RTC), Watchdog Timer (WDT), and multiple timers. It also incorporates 16 channels of 12-bit Analog-to-Digital Converters (ADCs) and dual 12-bit Digital-to-Analog Converters (DACs). The ATSAM3A4CA-AUR is housed in a 100-terminal, 14mm x 14mm, 0.5mm pitch fine-pitch quad flat package (LFQFP). It is suitable for industrial automation, automotive control, and advanced consumer electronics applications. Operating voltage ranges from 1.8V to 1.95V with an operating temperature range of -40°C to +85°C.
