AT91SAM9G25-CU

The AT91SAM9G25-CU is a Microchip Technology microprocessor IC based on a single ARM926EJ-S 32-bit core running at 400 MHz. Designed for embedded applications, it integrates a range of on-chip interfaces and memory controllers to support connectivity and system memory needs in industrial environments.

With support for DDR2, SDRAM and SRAM memory controllers, 10/100 Mbps Ethernet, and multiple USB 2.0 ports, the device targets embedded designs that require sustained processing, peripheral integration, and industrial operating temperature capability.

Key Features

• Core  ARM926EJ-S single 32‑bit core at 400 MHz for deterministic embedded processing.
• Memory Controllers  On-chip controllers for DDR2, SDRAM and SRAM to support varied system memory architectures.
• Connectivity  Integrated 10/100 Mbps Ethernet and three USB 2.0 ports to enable wired networking and USB peripheral support.
• System Interfaces  External Bus Interface (EBI/EMI) for flexible peripheral and external memory attachment.
• Package & Mounting  217‑LFBGA (15×15) surface-mount package for compact board-level integration.
• Industrial Grade & Temperature  Industrial grade component rated for operation from −40°C to 85°C.
• Regulatory Status  RoHS compliant.
• Graphics  No graphics acceleration (specified as not included), simplifying use in control- and connectivity-focused designs.

Typical Applications

• Embedded Control Systems  Use the ARM926EJ-S core and memory controllers to run control firmware and manage real‑time I/O in industrial equipment.
• Industrial Networking  10/100 Mbps Ethernet and multiple USB 2.0 ports support networked controllers, gateways, and data acquisition nodes.
• Human‑Machine Interfaces (HMI)  Processor performance and peripheral interfaces enable responsive UI control and peripheral connectivity for operator panels.

Unique Advantages

• Integrated memory support: DDR2, SDRAM and SRAM controllers reduce external memory interface complexity and expand design flexibility.
• Multiple high‑speed I/O options: Built-in Ethernet and three USB 2.0 ports provide ready connectivity for networked and USB‑based peripherals.
• Industrial temperature range: Rated from −40°C to 85°C for deployment in temperature‑challenging environments.
• Compact BGA package: 217‑LFBGA (15×15) allows dense board integration while maintaining necessary I/O pinout.
• Surface mount compatibility: Standard surface‑mount package simplifies automated assembly and scalable production.
