AT91SAM9G10-CU-999

The AT91SAM9G10-CU-999 is a single-core, 32-bit microprocessor IC based on the ARM926EJ-S core running at 266 MHz. It targets industrial embedded applications that require integrated system peripherals, deterministic timers, and extended temperature operation.

Designed with on-chip memory, a rich set of interfaces and a compact 217-LFBGA (15×15) package, the device provides a highly integrated platform for industrial HMI, networking, storage and control applications where robust peripheral integration and extended temperature range (-40 °C to 85 °C) are required.

Key Features

• Core & Performance  ARM926EJ-S 32-bit core at 266 MHz with architectural features from the SAM9G series including DSP instruction extensions, Jazelle technology for Java acceleration, and internal caches and write buffer for improved instruction/data throughput. The series lists performance up to 293 MIPS at 266 MHz.
• On-chip Memory  Includes embedded ROM and SRAM for single-cycle access at system bus speed (datasheet lists 32 KB internal ROM and 16 KB internal SRAM).
• External Memory Support  External Bus Interface (EBI) supports SDRAM, static memory, NAND Flash and CompactFlash; on-chip controllers for SDRAM and SRAM enable flexible external memory configurations.
• Display  Integrated LCD controller supports passive and active displays, STN color up to 16-bit per pixel and TFT up to 24-bit per pixel with resolutions up to 1280 × 860.
• Connectivity  10/100 Mbps Ethernet MAC, dual USB 2.0 full-speed host ports and a USB 2.0 full-speed device port (OHCI compliant) with on-chip transceivers, integrated FIFOs and dedicated DMA channels. Multimedia Card Interface (MCI) supports SDCard/SDIO and MultiMediaCard.
• System Integration  Bus matrix handling multiple masters/slaves, system controller with reset and shutdown controllers, clock generator, power management controller and advanced interrupt controller for streamlined system management.
• Timers, RTC and Debug  Includes Periodic Interval Timer (PIT), Watchdog Timer (WDT), Real-Time Timer (RTT) and an EmbeddedICE debug unit with debug communication channel support and a general-purpose DBGU UART.
• GPIO and DMA  Three 32-bit PIO controllers providing up to 96 programmable I/O lines, input-change interrupts and flexible I/O features, plus 19 peripheral DMA (PDC) channels for efficient data movement.
• Package & Environmental  217-LFBGA (15×15) surface-mount package, industrial grade operation, RoHS compliant and rated for operation from -40 °C to 85 °C.

Typical Applications

• Industrial Control  Real-time control and monitoring systems that benefit from the device’s timers, watchdog, robust I/O and industrial temperature rating.
• Human–Machine Interfaces (HMI)  Touch and display controllers using the integrated LCD controller for color TFT or STN panels and the on-chip graphics-supporting display pipeline.
• Networking & Gateways  Embedded network appliances and protocol gateways leveraging the integrated 10/100 Mbps Ethernet MAC and multiple USB ports for peripheral connectivity.
• Storage & Data Logging  Systems requiring SDCard/MMC storage and external NAND/Flash support via the EBI for data retention and removable media.

Unique Advantages

• Highly integrated peripheral set: Built-in Ethernet, USB host/device, LCD controller, MMC/SD interface and external bus support reduce the need for separate peripheral controllers.
• On-chip memory for fast boot and code execution: Internal ROM and SRAM provide single-cycle access at bus speed for critical code and fast startup.
• Deterministic system management: Comprehensive system controller features (reset, shutdown, clock and power management) and an advanced interrupt controller support reliable embedded operation.
• Flexible I/O and DMA: Up to 96 programmable I/O lines and 19 PDC channels enable efficient interfacing and low-CPU-overhead data transfers.
• Industrial temperature range and package: 217-LFBGA package and -40 °C to 85 °C rating align the device with industrial deployment requirements.
