Overview of STA1085ELA3 – ARM Cortex-R4 MPU, 450 MHz, 361-LFBGA

The STA1085ELA3 is a dual-core ARM® Cortex®-R4 microprocessor IC operating at 450 MHz, designed for embedded telematics applications. It integrates a companion ARM® Cortex®-M3 co-processor and a set of peripheral controllers to support high-performance connectivity and system control.

Targeted at automotive and telematics designs, the device combines performance, integration, and AEC-Q100 qualification to meet demanding temperature and reliability requirements in embedded environments.

Key Features

  • Core & Architecture  Dual ARM® Cortex®-R4 cores, 32-bit, running at 450 MHz, paired with an ARM® Cortex®-M3 co-processor for offloaded control tasks and real-time processing.
  • Memory & Controllers  Integrated SDRAM controller to interface with external memory for system and application code storage.
  • Display Interface  LCD controller support for driving vehicle or device displays.
  • Connectivity  Two USB 2.0 ports and CANbus interface provide high-speed peripheral connectivity and vehicle network integration.
  • Security  Boot security and Secure JTAG features to protect system boot and debugging access.
  • Power & I/O  3.3 V I/O voltage compatibility suitable for common embedded peripheral domains.
  • Package & Mounting  361-LFBGA (16×16) package in a surface-mount form factor for compact board integration.
  • Qualification & Temperature  Automotive-grade with AEC-Q100 qualification and an operating temperature range of −40 °C to 85 °C.
  • Environmental Compliance  RoHS compliant for adherence to environmental standards.

Typical Applications

  • Telematics Control Units  Dual-core processing and CANbus connectivity enable vehicle telematics functions and communication with vehicle networks.
  • Automotive Embedded Systems  AEC-Q100 qualification and −40 °C to 85 °C operating range make the device suitable for automotive-grade embedded controllers.
  • Infotainment and Display Control  Integrated LCD controller and USB 2.0 ports support display interfaces and media connectivity in in-vehicle systems.

Unique Advantages

  • Dual-Core Performance: Two ARM® Cortex®-R4 cores at 450 MHz provide headroom for compute-intensive telematics and control tasks.
  • Dedicated Co-Processor: ARM® Cortex®-M3 co-processor enables separation of real-time control from main application processing.
  • Automotive Qualification: AEC-Q100 qualification and automotive grade designation support reliability requirements for vehicle applications.
  • Integrated Connectivity: Built-in USB 2.0 (2 ports) and CANbus reduce external component count for connectivity and networking.
  • Security Features: Boot security and Secure JTAG help protect system integrity and debugging access during development and deployment.
  • Compact Packaging: 361-LFBGA (16×16) surface-mount package enables high-density board designs in space-constrained applications.
