STA1078EOA3

The STA1078EOA3 is an ARM® Cortex®-R4 single-core, 32‑bit microprocessor running at 450 MHz, designed for embedded telematics applications. It combines real-time processing with integrated peripheral support—including an ARM® Cortex®-M3 coprocessor, SDRAM controller and display interfaces—to address systems that require balanced compute, connectivity and human‑machine interaction.

With a 256‑TFBGA (11×11) surface‑mount package, 3.3 V I/O and an extended operating range of −40 °C to 85 °C, the STA1078EOA3 targets embedded designs where integration, I/O flexibility and predictable performance are important.
