STMicroelectronics STA2064N

Overview

STA2064N from STMicroelectronics is a Cartesio™ family infotainment application processor integrating an ARM1176 533 MHz host CPU, embedded GPS baseband (HPGPS_G2), LP DDR/DDR2 memory controller (16-bit, 333 MHz DDR2), JPEG baseline decoder (16 Mpix/sec), and 3D smart graphic accelerator. It serves as the central SoC in vehicle head units and portable navigation devices (PNDs), delivering concurrent audio/video processing, touch-screen control, and high-sensitivity satellite positioning.

For engineers reviewing the STA2064N datasheet, STA2064N pinout, STA2064N application, or STA2064N equivalent, key selection considerations include its dual SD/MMC boot capability, CAN absence (vs. automotive STA2064A), 1.8 V/2.5 V/3.3 V programmable I/O voltage support, and integrated GPS subsystem requiring companion RF chip STA5630.

Technical Context

The STA2064N implements a heterogeneous dual-domain architecture: an ARM1176-JZF core (533 MHz, 32 KB I-cache/32 KB D-cache, VFP unit) handles application-layer OS tasks, while a dedicated ARM966-based GPS subsystem (clocked up to 208 MHz) runs ST's proprietary HPGPS_G2 baseband firmware for parallel 8-satellite acquisition and 32-channel tracking. Memory subsystem includes 32 KB eSRAM and configurable 16-bit DDR2/LP DDR interface supporting up to 2 Gbit density.

System-level features include a 64-channel vector interrupt controller (VIC), two 8-channel DMA controllers with 32 request lines each, three multichannel serial ports (MSP/I²S/TDM), SPDIF input with C3 Reed-Solomon decoding, and a 4-wire touchscreen controller with 12-bit SAR ADC (1 μs conversion time) and 128-coordinate FIFO. Power management partitions logic into Always_ON (VDDON = 1.25 ±3% V), core (VDD), and multi-rail I/O domains (VDDIO_ON = 1.8 ±10% V).

Key Specifications

Pinout & Package

STA2064N is housed in a TFBGA289 package (15 mm × 15 mm × 1.2 mm, 0.8 mm pitch) with 289 solder balls arranged in a 17 × 17 grid (corner balls omitted). The package supports fine-pitch PCB assembly and thermal dissipation via exposed die paddle (connected to VSS).

FAQ

Does STA2064N include an integrated GPS RF front-end?

No. STA2064N integrates only the GPS baseband (HPGPS_G2) and requires the companion RF chip STA5630 to receive and downconvert L1-band signals. The baseband accepts a 3-bit 4 MHz IF input from STA5630 and performs acquisition, tracking, and PVT computation internally.

What is the maximum DDR2 memory bandwidth supported by STA2064N?

STA2064N supports DDR2 at 333 MHz with a 16-bit data bus, delivering up to 666 MB/s peak bandwidth. The controller supports two chip selects and is configured for 256 MB addressable space, compatible with standard DDR2-667 SDRAM components.

Can STA2064N operate without external SDRAM?

No. STA2064N requires external LP DDR or DDR2 memory for program execution and data storage. It includes only 32 KB of embedded SRAM for boot code and critical low-latency buffers - insufficient for full OS operation.

Is the CAN interface available on STA2064N?

No. CAN is exclusive to the automotive-grade STA2064A variant. STA2064N omits the CAN controller and associated I/O ring E voltage configuration for CAN transceiver biasing, confirming its targeting of consumer/navigation applications without vehicle bus requirements.
