Product details
Overview
AM3715CBC 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), 45-nm CMOS process, and 515-pin s-PBGA package (CBC suffix, .65mm/.5mm ball pitch). It serves as the application processor subsystem in embedded systems requiring high-performance multimedia, real-time OS support (Linux/Android), and integrated video/audio interfaces.
For engineers reviewing the AM3715CBC datasheet, AM3715CBC pinout, AM3715CBC application, or AM3715CBC equivalent, this page delivers verified technical context, validated package mapping, confirmed graphics acceleration capability, exact ball-grid terminal roles, and two manufacturer-validated alternative MPUs for design continuity planning.
Technical Context
The AM3715CBC implements an in-order, dual-issue, superscalar ARMv7 architecture with TrustZone® security, Thumb®-2 instruction set, and NEON™ SIMD coprocessor. Its memory subsystem includes 32KB L1 instruction/data caches, 256KB unified L2 cache, 64KB on-chip SRAM, and 32KB ROM - all operating under adaptive core voltage (0.9–1.2 V) and SmartReflex™ AVS.
Graphics processing is handled by the dedicated POWERVR SGX™ engine supporting OpenGLES 1.1/2.0 and OpenVG 1.0, delivering up to 20 MPoly/sec via a tile-based, multi-threaded universal scalable shader engine. Video I/O includes BT.601/BT.656 8-/10-bit YCbCr 4:2:2 interface, dual-output 3-layer display processor, and hardware resize engine (1/4x to 4x).

Equivalent & Alternatives
The following parts are listed as comparable options for similar ARM application processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM3703CBC | No POWERVR SGX graphics engine; identical CPU, memory subsystem, and peripheral set otherwise | Suitable where UI is software-rendered or minimal (e.g., text-based HMIs); lacks hardware-accelerated 3D/OpenVG | Select AM3703CBC when graphics acceleration is unnecessary and BOM cost reduction is prioritized |
| AM3358BZCZ100 | ARM Cortex-A8 @ 1 GHz, no SGX, but adds PRU-ICSS for real-time I/O offload; different pinout and memory controller | Better suited for industrial protocol gateways (EtherCAT, PROFIBUS) due to programmable real-time units; no video display engine | Choose AM3358BZCZ100 when deterministic low-latency I/O control outweighs multimedia capability |
Compared with AM3715CBC, AM3703CBC removes graphics acceleration while retaining identical CPU performance and peripheral count - ideal for cost-sensitive non-graphic applications; AM3358BZCZ100 trades display/video features for PRU-based real-time I/O, requiring PCB redesign but enabling hard real-time edge control.

FAQ
What is the maximum supported SDRAM capacity for AM3715CBC?
The AM3715CBC SDRC supports up to 1 GB of total SDRAM address space using 16-bit or 32-bit wide LPDDR/DDR2 memory. This is implemented via configurable row/column/bank addressing with programmable timing registers, allowing optimization for specific memory parts such as Micron MT46H32M16LF or ISSI IS42S16160J.
Does AM3715CBC include hardware encryption acceleration?
No, the AM3715CBC does not integrate dedicated cryptographic accelerators (e.g., AES, SHA, RSA engines). Security relies on ARM TrustZone® for memory isolation and software-based crypto libraries. For hardware-accelerated encryption, TI recommends the AM437x or AM57x families which include Crypto Acceleration Engine (CAE) modules.
Can AM3715CBC operate without external SDRAM?
No - the AM3715CBC requires external SDRAM for normal operation. While it contains 64KB on-chip SRAM and 32KB ROM, these are insufficient for booting Linux or Android. The SDRC block must be initialized and connected to compliant DDR2/LPDDR memory; boot sequences always begin from external NAND/NOR or MMC, then load into SDRAM.
What video output interfaces does AM3715CBC support natively?
The AM3715CBC supports native parallel video outputs including BT.601/BT.656 8-/10-bit YCbCr 4:2:2, RGB666/RGB888, and digital LCD signals via its Display Subsystem (DSS). It does not include HDMI or DisplayPort transmitters - those require external PHYs such as TI TFP410 or Parade PS8338, connected via DSS parallel bus.
Is AM3715CBC pin-compatible with AM3703CBC?
Yes - AM3715CBC and AM3703CBC share identical 515-pin s-PBGA (CBC) package dimensions, ball pitch, and pinout. They differ only in internal silicon configuration (SGX presence), making them drop-in replacements at the PCB level. No layout changes are required when migrating between these variants.
