Operating at 120MHz, it features 2MB of dual-bank Flash memory with read-while-write capability and 160KB of SRAM. The dual-core architecture enables concurrent execution of communication and application tasks. Integrated hardware cryptography supports AES-128\/192\/256, DES, TDES, RSA, and ECC for secure data communication. Connectivity includes dual CAN 2.0A\/B controllers, IEEE 1588 Ethernet MAC, USB 2.0 OTG high-speed with on-chip PHY, multiple SPI\/I2C\/USART interfaces, and SDIO. The device is available in a 100-pin TQFP package rated for -40 to 85 C operation.","working_principle":"The ATSAM4SD32CA-CUR is built around a dual-core ARM Cortex-M4F architecture with shared peripherals. Key subsystems include: (1) Dual Cortex-M4F Cores - each core executes Thumb-2 instructions with hardware FPU, sharing the peripheral bus and memory via an AHB bus matrix; (2) Dual-Bank Flash - 2MB split into two 1MB banks enabling read-while-write operation; (3) SRAM - 160KB with multiple ports for concurrent DMA and CPU access; (4) Crypto Engine - hardware accelerators for AES, DES\/TDES, RSA, and ECC operations; (5) Communication Subsystem - dual CAN with mailboxes, Ethernet MAC with DMA and IEEE 1588 timestamping, USB HS with dedicated DMA; (6) DMA Controller - multi-channel DMA offloads data transfers from both CPU cores.","pin_description":"
