STA1080EOA

The STA1080EOA is a 32-bit microprocessor IC based on a single ARM® Cortex®-R4 core running at 450 MHz, designed for embedded telematics applications. It integrates a range of on-chip controllers and interfaces—such as SDRAM control, LCD and touchscreen display interfaces, USB 2.0, and CAN—to address high-performance embedded and automotive telematics designs.

With automotive-grade qualification (AEC-Q100) and an operating temperature range of −40 °C to 85 °C, the device targets designs where performance, on-chip integration, and industry qualification are required.

Key Features

• Core  Single ARM® Cortex®-R4 core, 32-bit, running at 450 MHz for deterministic, real-time processing.
• Co-processor  Integrated ARM® Cortex®-M3 co-processor for offloading auxiliary control tasks and system supervision.
• Memory and Controllers  SDRAM controller on-chip to interface with external SDRAM devices for main system memory.
• Display and Graphics  LCD and touchscreen display interface controllers plus graphics acceleration to drive vehicle displays and user interfaces.
• Interfaces  USB 2.0 (1) host/device interface and CAN connectivity for in-vehicle communications and peripheral connectivity.
• Power and I/O  I/O operates at 3.3 V, matching common automotive and embedded I/O domains.
• Package and Mounting  361-LFBGA package (16×16 mm) in a surface-mount form factor optimized for compact board designs.
• Qualification and Environmental  Automotive grade with AEC-Q100 qualification and RoHS compliance; specified operating temperature −40 °C to 85 °C.

Typical Applications

• Automotive Telematics Units  Integration of processing, communications (CAN) and display interfaces for telematics control modules.
• In-vehicle Display Systems  Driving LCD and touchscreen interfaces with graphics acceleration for driver and passenger displays.
• Vehicle Communications Gateways  USB 2.0 and CAN support for interfacing diagnostics, peripherals, and networked vehicle systems.
• Embedded Control Platforms  Real-time processing with the Cortex-R4 core and an auxiliary Cortex-M3 coprocessor for mixed-control workloads.

Unique Advantages

• Deterministic Real-time Performance: 450 MHz ARM® Cortex®-R4 core provides predictable, real-time processing for control and telematics tasks.
• Integrated Auxiliary Processing: ARM® Cortex®-M3 co-processor enables separation of control and supervisory functions without external MCUs.
• Rich On-chip Interfaces: Built-in SDRAM controller, LCD/touchscreen controllers, USB 2.0 and CAN reduce external component count and simplify board design.
• Automotive Qualification: AEC-Q100 qualification and a −40 °C to 85 °C operating range support deployment in automotive telematics environments.
• Compact Industrial Package: 361-LFBGA (16×16) surface-mount package balances thermal performance and PCB area for embedded systems.
• Compliance and Environmental: RoHS-compliant construction for regulatory and manufacturing alignment.
