STA2065N

Overview

The STA2065N is a Cartesio™ family infotainment application processor from STMicroelectronics, designed for vehicle head units and mobile navigation systems. It integrates an ARM1176 host processor operating at 533 MHz with vector floating-point capabilities and a high-performance embedded GPS subsystem supporting up to 8 parallel acquisition engines and 32 tracking channels. The device features advanced power management with separated power islands and dynamic frequency scaling. System infrastructure includes LP DDR/DDR2 controllers, static memory controllers, dual DMA engines, and extensive I/O interfaces such as USB 2.0 OTG, SD/MMC, CAN, and various audio/video ports.

• ARM1176 host processor running at 533 MHz with 32 KB instruction and data caches
• Embedded GPS subsystem with 32 tracking channels and multibit signal processing hardware
• Advanced power management featuring separated power islands and dynamic core frequency scaling
• System infrastructure including LP DDR/DDR2 controller, FSMC, dual DMA controllers, and 160 GPIOs

Applications

• Vehicle head units
• Mobile navigation (PND)
• Telematics systems
• Infotainment applications
• Advanced audio and connectivity systems

Procurement Notes

Verify the specific ordering suffix against official STMicroelectronics documentation to confirm qualification grade and interface configurations. The STA2065N denotes the consumer-grade variant with a 533 MHz CPU frequency and no integrated CAN modules. Ensure compatibility with the required TFBGA372+100 package specifications and ambient temperature range of -40°C to +85°C during component selection.

Selection Notes

Select the STA2065N for applications requiring a 533 MHz ARM1176 processor without automotive CAN requirements. Consider the integrated GPS baseband if satellite positioning is needed without external processors. Evaluate the memory interface options, specifically support for LP DDR or DDR2 SDRAM, and verify that the available I/O voltage rings (1.8V, 2.5V, 3.3V) match the system design constraints.

Part Context

The STA2065N belongs to the Cartesio™ family of infotainment application processors. It shares architectural similarities with other variants like the STA2065P (624 MHz) and STA2065A (Automotive grade with CAN). This family targets cost-effective solutions for multimedia and navigation by combining host processing power with embedded GPS functionality in a single SoC.
