AT91SAM9M11-CU

The AT91SAM9M11-CU is a 32-bit microprocessor IC based on the ARM926EJ-S core running at 400 MHz, designed for embedded applications. Manufactured by Microchip Technology, this device targets industrial embedded systems that require a single-core 32-bit processor with a broad set of on-chip interfaces.

Its combination of a 400 MHz ARM926EJ-S core, multiple memory controller options, display and Ethernet support, and industrial temperature range make it suitable for networked and human-machine interface designs in embedded and industrial markets.

Key Features

• Core and Performance — ARM926EJ-S single-core 32-bit processor running at 400 MHz for deterministic embedded processing.
• Memory Controllers — Supports LPDDR, LPSDR, DDR2, SDR and SRAM memory types to accommodate a range of memory architectures and system requirements.
• Display and Multimedia Interfaces — Integrated controllers for LCD, touchscreen and video decoder support applications that require local user interfaces and video capability.
• Networking — 10/100 Mbps Ethernet support enables wired network connectivity for industrial and embedded communications.
• USB Connectivity — USB 2.0 (3) functionality provides USB interfacing options for peripherals and host/client roles.
• Industrial Grade — Grade: Industrial with an operating temperature of –40 °C to 85 °C for deployment in temperature-challenging environments.
• Package and Mounting — Supplied in a 324-TFBGA (15 × 15 mm) package, designed for surface-mount assembly in compact embedded boards.
• Graphics Acceleration — No dedicated graphics acceleration; display support is via integrated display and video decoder controllers.

Typical Applications

• Industrial Control Systems — Use the 400 MHz ARM926EJ-S core and industrial temperature rating for control and monitoring applications in harsh environments.
