Texas Instruments AM3715CBP

Overview

AM3715CBP from Texas Instruments is a Sitara™ ARM® Cortex™-A8 microprocessor with up to 1-GHz operation, POWERVR SGX™ graphics accelerator (AM3715 only), 256KB L2 cache, 45-nm CMOS process, and 515-pin s-PBGA (CBP) package. It serves as the application processor subsystem in embedded systems requiring high-performance multimedia, real-time OS support (Linux/Android), and integrated video capture/display.

For engineers reviewing the AM3715CBP datasheet, AM3715CBP pinout, AM3715CBP application, or AM3715CBP equivalent, key selection considerations include its 1-GHz adaptive core voltage (0.9–1.2 V), dual USB 2.0 subsystems (OTG + multiport host), 5 McBSP audio interfaces with SIDETONE support, and POP-capable memory stacking for compact system-on-module designs.

Technical Context

The AM3715CBP implements an in-order, dual-issue, superscalar ARMv7 architecture with TrustZone® security, Thumb®-2 instruction set, and NEON™ SIMD coprocessor. Its memory subsystem integrates SDRC (16/32-bit SDRAM controller) and GPMC (NOR/NAND/SRAM interface) with ECC Hamming code support for NAND flash.

Graphics acceleration is handled by the tile-based POWERVR SGX engine delivering up to 20 MPoly/sec, supporting OpenGLES 1.1/2.0 and OpenVG 1.0. Video processing includes a dedicated ISP with BT.601/BT.656 8-/10-bit YCbCr 4:2:2 interface, resize engine (1/4x–4x), and dual-output 3-layer display processor.

Key Specifications

Pinout & Package

AM3715CBP uses a 515-ball s-PBGA package (CBP suffix) with 0.5 mm ball pitch on top layer and 0.4 mm on bottom layer. The package supports Package-on-Package (POP) memory stacking and features 188 multiplexed GPIO pins.

FAQ

What is the maximum operating frequency of the AM3715CBP and under what voltage conditions?

The AM3715CBP operates at up to 1 GHz with an adaptive core logic voltage range of 0.9 V to 1.2 V, optimized via SmartReflex AVS. Default OPP voltages are specified in SPRS616F, and actual frequency/voltage combinations depend on thermal and silicon characteristics-verified per unit during production test. The AM3715CBP maintains full functionality across commercial and extended temperature grades at all supported OPPs.

Does the AM3715CBP include an integrated graphics accelerator, and is it present in all variants?

Yes, the AM3715CBP includes the POWERVR SGX™ graphics accelerator delivering up to 20 MPoly/sec and supporting OpenGLES 1.1/2.0 and OpenVG 1.0. This feature is exclusive to the AM3715 variant; the AM3703CBP omits the SGX block entirely. Graphics driver support is provided by TI for Linux and Android, and the AM3715CBP's tile-based architecture enables efficient memory bandwidth usage in embedded UI applications.

How does the AM3715CBP handle external memory interfaces, and what types of memory are supported?

The AM3715CBP integrates two independent memory controllers: the SDRC supports LPDDR, DDR2, and mobile DDR up to 1 GB address space, while the GPMC provides a 16-bit multiplexed bus with up to 8 chip selects for NOR flash, NAND flash (with built-in Hamming ECC), SRAM, and FPGA/CPLD interfaces. Both controllers support asynchronous protocols and are configured via memory-mapped registers-enabling glueless connections without external logic.

What USB capabilities does the AM3715CBP provide, and how are they implemented physically?

The AM3715CBP integrates two fully independent USB 2.0 subsystems: a high-speed OTG port and a high-speed multiport host controller. Both use ULPI (UTMI+ Low Pin Count) interface-requiring only 12 or 8 signal pins each-eliminating external PHY components. The OTG port supports device/host/peripheral roles; the host port supports up to 12 downstream ports via external hub. All USB functions are managed by dedicated DMA and controller logic within the AM3715CBP.

Is the AM3715CBP pin-compatible with other members of the Sitara AM37x family, and what package options exist?

The AM3715CBP uses the 515-pin s-PBGA CBP package (0.5 mm / 0.4 mm dual-pitch), which is mechanically and electrically pin-compatible with the AM3703CBP in the same package. However, it is not compatible with the CBC (0.65 mm / 0.5 mm) or CUS (423-pin) variants due to differing ball maps and pitch. TI confirms CBP-to-CBP substitution is valid for AM3715/AM3703, preserving PCB layout and interconnect integrity.
