Microchip AT91SAM9G35-CU-999: A Comprehensive Overview of the ARM926EJ-S Microprocessor
The Microchip AT91SAM9G35-CU-999 represents a significant offering in the realm of embedded microprocessors, built around the robust and proven ARM926EJ-S core. This system-on-chip (SoC) is engineered to deliver a powerful combination of high processing performance and low power consumption, making it an ideal solution for a wide array of demanding industrial, medical, and consumer applications.
At the heart of this microprocessor lies the ARM926EJ-S core, which operates at speeds up to 400 MHz. This core integrates a 32-bit RISC processor, a Memory Management Unit (MMU) for advanced operating system support, and a Jazelle technology accelerator for enhanced Java execution. This combination ensures efficient handling of complex software stacks, including full-featured operating systems like Linux, Android, and Windows CE.
A key strength of the AT91SAM9G35 is its highly integrated peripheral set, designed to minimize external component count and reduce total system cost. It features a DDR2/LPDDR SDRAM controller for high-speed memory access, which is crucial for data-intensive applications. For graphical user interfaces, it includes an LCD controller supporting resolutions up to WSVGA, enabling the development of products with rich, interactive displays.
Connectivity is a cornerstone of its design. The chip is equipped with a comprehensive suite of communication interfaces, including 10/100 Ethernet MAC with IEEE 1588 support for networked and time-synchronized industrial systems. It also offers dual USB 2.0 Host ports and a Device port, a High-Speed SDIO/SD/MMC card interface, and multiple USARTs, SPIs, and TWIs, providing designers with extensive options for interfacing with other components and peripherals.
Furthermore, the AT91SAM9G35 incorporates critical security and reliability features. It includes hardware encryption engines (AES, TDES, SHA) for securing data, a secure boot ROM, and tamper detection pins, making it suitable for applications where data integrity and security are paramount. Its extended temperature range and robust construction cater to the harsh environments typical in industrial automation.
In summary, the AT91SAM9G35-CU-999 leverages the mature ARM926EJ-S architecture to deliver a balanced, highly integrated, and secure processing platform for next-generation embedded designs.
