STMicroelectronics STA2065N

Overview

STA2065N from STMicroelectronics is a consumer-grade automotive infotainment SoC integrating an ARM1176 533 MHz host processor, embedded GPS baseband (HPGPS_G2), LPDDR/DDR2 memory controller (333 MHz DDR2), color LCD controller with integrated touchscreen ADC, and dual USB 2.0 OTG interfaces. It delivers real-time PVT computation, JPEG baseline decoding (16 Mpix/sec), and 3D graphics acceleration for vehicle head units and portable navigation devices.

For engineers reviewing the STA2065N datasheet, STA2065N pinout, STA2065N application, or STA2065N equivalent, key selection considerations include its GPS acquisition architecture (8-satellite parallel engine), power island partitioning for deep-sleep operation, 160 GPIOs across five 32-bit ports, and absence of CAN controllers in the N variant per Table 1.

Technical Context

The STA2065N implements a dual-domain SoC architecture: an ARM1176-JZF CPU subsystem (533 MHz, 32 KB I/D cache, VFP unit) tightly coupled with a dedicated ARM966-based GPS baseband (HPGPS_G2) running at 208–39 MHz. The GPS subsystem features 32 tracking channels, 5 correlators per channel, and hardware BCH error correction for NAND flash.

System infrastructure includes a 64-channel VIC, two 8-channel DMA controllers supporting 32 requests each, flexible static memory controller (FSMC) with hardware ECC for SLC/MLC NAND, and a multisupply IO ring supporting 1.8 V / 2.5 V / 3.3 V programmable voltage levels with slew rate control.

Key Specifications

Pinout & Package

STA2065N is housed in a TFBGA372+100 package (16 mm × 16 mm × 1.2 mm, 0.65 mm pitch) with 472 total terminals. The package supports fine-pitch routing for high-density automotive PCBs and thermal dissipation via exposed die paddle.

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar infotainment application processor applications.

Compared with STA2065P, the STA2065N trades 91 MHz CPU headroom for tighter frequency binning and lower test cost; compared with STA2065A, it omits CAN controllers and automotive temp rating - making it optimal for cost-sensitive consumer PNDs where CAN is unused and ambient operating range stays within −40 °C to +85 °C.

Availability

STA2065N is available at Aetrix Electronics and suitable for in-vehicle navigation head units, portable navigation devices (PND), and telematics control units requiring stable component supply, long-lifecycle support, and automotive-grade traceability.

Supply support for STA2065N includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

STMicroelectronics is a global semiconductor leader headquartered in Geneva, Switzerland, designing and manufacturing microcontrollers, power ICs, sensors, and automotive SoCs since 1987.

The Cartesio™ family - including STA2065N - was engineered specifically for cost-optimized infotainment and navigation systems, integrating GPS baseband, multimedia accelerators, and automotive-ready interfaces into a single die.

FAQ

What is the maximum DDR2 speed supported by STA2065N?

The STA2065N DDR2 controller supports up to 333 MHz data rate (166 MHz clock) with 16- or 32-bit bus width. This enables 533 MB/s peak bandwidth for framebuffer and application memory, validated per JEDEC DDR2-667 specification with on-die termination and programmable drive strength.

Does STA2065N include hardware JPEG encoding capability?

No, the STA2065N integrates only a JPEG baseline profile decoder capable of 16 Mpix/sec throughput. It does not include JPEG encoder hardware; encoding must be performed in software on the ARM1176 core or offloaded to an external ISP.

How many USB endpoints does STA2065N support per interface?

Each USB 2.0 OTG interface (USB0 and USB1) supports up to 7 bidirectional endpoints plus control endpoint 0. Endpoint configuration is fully programmable via AMBA APB registers, with dynamic FIFO allocation enabling flexible descriptor-based transfer management.

Is the touchscreen controller compatible with projected capacitive (PCAP) panels?

No, the integrated touchscreen controller is designed exclusively for 4-wire resistive touchscreens. It provides X/Y plate drive and 12-bit SAR ADC measurement but lacks the high-frequency excitation and mutual capacitance sensing required for PCAP panels.
