概要

Description

ATSAMA5D21C-CU is a Microchip/Atmel SAMA5D2 family member: a 32-bit ARM Cortex-A5 based embedded MPU/SoC designed for Linux/RTOS applications. It bundles a Cortex-A5 core with on‑chip memory interfaces and a rich peripheral set, enabling a wide range of embedded systems.
Key features (typical):
- ARM Cortex-A5 core, up to high MHz, with memory protection and DMA
- USB: OTG, device/host options
- Ethernet MAC (10/100 or higher)
- CAN, multiple UARTs, SPI, I2C
- SD/MMC interface, PWM, timers, and ADC
- External DRAM/SRAM interfaces (DDR2/DDR3, etc.)
- Hardware crypto accelerators and security features (secure boot, cryptography)
- Toolchain support: Atmel Studio/MPLAB X, GCC, Linux BSPs
Applications: industrial automation, HMI, networking devices, and other embedded systems needing a capable Linux/RTOS platform in a cost-effective ARM MPSoC. Packaging: the “-CU” suffix denotes a specific QFP/LQFP-style package option. For exact specs and packaging, consult the official datasheet.
