Texas Instruments AM3715CBPA

Overview

AM3715CBPA from Texas Instruments is a high-performance 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 support for Linux, Android, and Windows Embedded CE - deployed in portable data terminals and automotive infotainment systems.

For engineers reviewing the AM3715CBPA datasheet, AM3715CBPA pinout, AM3715CBPA application, or AM3715CBPA equivalent, key selection criteria include its 515-pin s-PBGA (CBP) package, dual-issue superscalar core, SmartReflex™ AVS power management, and integrated display/ISP/USB OTG subsystems for embedded multimedia designs.

Technical Context

The AM3715CBPA implements an in-order, dual-issue, superscalar ARMv7 architecture with TrustZone® security, Thumb®-2 instruction set, and NEON™ SIMD coprocessor - enabling fine-grained task switching and load balancing across real-time and application workloads.

Its memory subsystem integrates a 32KB/32KB L1 instruction/data cache, 256KB unified L2 cache, 64KB on-chip SRAM, 32KB ROM, SDRC controller for LPDDR/DDR2, and GPMC supporting NOR/NAND flash, SRAM, and FPGA glueless interfacing - all managed via hierarchical L3/L4 interconnects.

Key Specifications

Pinout & Package

AM3715CBPA is housed in a 515-ball, 0.5 mm (top) / 0.4 mm (bottom) pitch s-PBGA package (CBP suffix), optimized for Package-on-Package (POP) memory stacking. Pin assignments are defined across four quadrants (A–D) with multiplexed I/O functions including GPMC, SDRC, McBSP, McSPI, USB, and display interfaces.

FAQ

What is the maximum operating frequency of the AM3715CBPA?

The AM3715CBPA operates at up to 1 GHz under commercial temperature conditions (0°C to 90°C junction). This frequency is achieved using adaptive voltage scaling via SmartReflex AVS, with default OPP voltages ranging from 0.9 V to 1.2 V for the processor core. The AM3715CBPA datasheet specifies timing margins and thermal derating curves for sustained operation at this rate.

Does the AM3715CBPA include an integrated graphics accelerator?

Yes, the AM3715CBPA 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 capability is exclusive to the AM3715 variant - the AM3703CBPA omits the SGX block. The AM3715CBPA uses tile-based rendering and a universal scalable shader engine for efficient 2D/3D composition.

What memory interfaces does the AM3715CBPA support?

The AM3715CBPA supports two primary memory controllers: the SDRAM Controller (SDRC) for LPDDR/DDR2 with 32-bit data bus and DQS strobing, and the General Purpose Memory Controller (GPMC) for NOR/NAND flash (with Hamming ECC), SRAM, and FPGA interfacing. It also includes 64KB on-chip SRAM and 32KB ROM for boot and critical firmware storage.

Is the AM3715CBPA pin-compatible with other Sitara processors?

The AM3715CBPA shares the same 515-pin CBP package and ball map with the AM3703CBPA, enabling direct PCB compatibility between the two variants. However, it is not pin-compatible with the 423-pin CUS package (e.g., AM3517CBB) or CBC-package variants due to differing pin counts, ball pitch, and I/O allocation - layout reuse requires matching package suffixes.

What operating systems are supported on the AM3715CBPA?

The AM3715CBPA supports Linux, Android, and Windows Embedded CE - all available free of charge from Texas Instruments with BSPs, drivers, and documentation. Its ARMv7 architecture, TrustZone security extensions, and NEON SIMD unit ensure broad compatibility with real-time and application-level OS environments used in industrial, medical, and automotive deployments.
