Product details
Overview
AM3715CUS from Texas Instruments is a Sitara™ ARM® Cortex™-A8 microprocessor with up to 1-GHz operation, 256KB L2 cache, POWERVR SGX graphics accelerator (AM3715 only), and integrated SDRC/GPMC memory controllers. It supports Linux, Android, and Windows Embedded CE, and targets high-performance embedded applications requiring multimedia acceleration and real-time I/O.
For engineers reviewing the AM3715CUS datasheet, AM3715CUS pinout, AM3715CUS application, or AM3715CUS equivalent, key selection considerations include its 423-pin s-PBGA (CUS) package, 45-nm process, SmartReflex™ AVS power management, dual USB subsystems (OTG + multiport host), and camera ISP with BT.656 interface - all critical for portable HMI, infotainment, and industrial vision designs.
Technical Context
The AM3715CUS implements an in-order, dual-issue, superscalar ARMv7 architecture with TrustZone® security, NEON™ SIMD coprocessor, and 32KB/32KB L1 instruction/data caches. Its memory subsystem includes a 16-/32-bit SDRAM controller (SDRC) supporting LPDDR/DDR2 and a flexible 16-bit multiplexed GPMC for NAND/NOR flash, SRAM, and FPGA glueless interfacing.
Graphics are handled by the dedicated POWERVR SGX engine delivering up to 20 MPoly/sec, while video processing leverages a dual-output 3-layer display processor with temporal dithering and SDTV QCIF support. The device integrates five McBSP ports (two with sidetone), four McSPI interfaces, three high-speed I²C controllers, and six UARTs - including one with IrDA - enabling complex peripheral orchestration without external logic.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ARM application processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM3703CUS | No POWERVR SGX graphics accelerator; identical CPU, memory, and peripheral subsystems. | Suitable where UI rendering is software-based or minimal; lower thermal envelope and cost. | Select AM3703CUS when graphics acceleration is unnecessary and BOM cost reduction is prioritized. |
| AM3358BZCZ100 | ARM Cortex-A8 @ 1 GHz, but no SGX; features PRU-ICSS for real-time I/O offload and enhanced industrial connectivity. | Better suited for deterministic industrial control (e.g., motor drives, IO modules); lacks camera ISP and dual-display processor. | Choose AM3358BZCZ100 for applications requiring PRU-based real-time peripherals or industrial Ethernet protocols over multimedia capability. |
Compared with AM3703CUS, the AM3715CUS adds hardware graphics acceleration critical for rich UIs, while AM3358BZCZ100 trades multimedia features for real-time I/O flexibility via PRUs - making each optimal for distinct segments: infotainment (AM3715CUS), cost-sensitive general-purpose (AM3703CUS), or industrial automation (AM3358BZCZ100).

FAQ
What is the maximum operating frequency of the AM3715CUS?
The AM3715CUS operates at up to 1 GHz under adaptive voltage scaling (AVS) with SmartReflex™ technology. This frequency is achieved with a core logic voltage of 0.9 V to 1.2 V and is validated across commercial and extended temperature grades. The AM3715CUS datasheet specifies default OPP voltages, but actual performance may be optimized further using dynamic DVFS based on thermal and workload conditions.
Does the AM3715CUS include an integrated graphics accelerator?
Yes, the AM3715CUS integrates a POWERVR SGX graphics accelerator delivering up to 20 MPoly/sec, supporting OpenGL ES 1.1/2.0 and OpenVG 1.0 APIs. This hardware block is absent in the pin-compatible AM3703CUS variant. The SGX engine enables accelerated UI rendering, video compositing, and 2D/3D graphics - critical for infotainment and HMI applications where software-only rendering would overload the Cortex-A8 core.
What camera interfaces does the AM3715CUS support?
The AM3715CUS features a dedicated Camera Image Signal Processor (ISP) with parallel interface supporting BT.601/BT.656 (8-/10-bit YCbCr 4:2:2), CCD and CMOS imager input, and hardware resize engine (1/4x to 4x). It accepts pixel clock, HSYNC, VSYNC, FIELD, and 12-bit parallel data - enabling direct connection to common industrial and medical image sensors without external video interface ICs.
Is the AM3715CUS pin-compatible with other Sitara processors?
The AM3715CUS shares the 423-ball s-PBGA (CUS) package footprint with the AM3703CUS, enabling mechanical compatibility and PCB reuse between the two variants. However, it is not pin-compatible with CBP/CBC packages (515-ball) or later Sitara families like AM437x or AM57x. Signal-level compatibility is maintained within the AM37x CUS group, though SGX-related pins are NC on AM3703CUS.
What power management features does the AM3715CUS offer?
The AM3715CUS implements SmartReflex™ AVS with dynamic voltage and frequency scaling (DVFS), adaptive core logic voltage (0.9–1.1 V), and multiple power domains (MPU, IVA, CORE, MEM). It supports fine-grained task switching, load balancing, and idle state management (including deep sleep modes). These features reduce active power consumption by up to 40% compared to fixed-voltage operation while maintaining real-time responsiveness.
