Product details
Overview
AM3703CBPD100 from Texas Instruments is a Sitara™ ARM® Cortex™-A8 microprocessor operating up to 1 GHz with adaptive core voltage (0.9–1.2 V), integrated 256KB L2 cache, POWERVR SGX graphics accelerator (AM3715 only - AM3703 excludes SGX), and support for Linux, Android, and Windows Embedded CE. It targets portable data terminals, automotive infotainment, and industrial HMI systems requiring high-performance application processing with low-power operation.
For engineers reviewing the AM3703CBPD100 datasheet, AM3703CBPD100 pinout, AM3703CBPD100 application, or AM3703CBPD100 equivalent, key selection criteria include its 515-pin s-PBGA (CBP) package, dual USB 2.0 OTG/host subsystems, 5 McBSP audio interfaces, GPMC/NAND/SDRAM memory controller, and absence of on-die POWERVR SGX - distinguishing it from AM3715.
Technical Context
The AM3703CBPD100 implements the ARMv7 architecture with TrustZone security, NEON SIMD coprocessor, and in-order dual-issue superscalar execution. It integrates a 32KB/32KB L1 instruction/data cache, 256KB unified L2 cache, 64KB on-chip SRAM, and 32KB ROM for boot.
Its memory subsystem includes an SDRAM controller (SDRC) supporting LPDDR/DDR2 with SMS scheduler and rotation engine, plus a General Purpose Memory Controller (GPMC) with eight chip selects for NOR/NAND/SRAM. The device uses SmartReflex™ AVS for dynamic voltage and frequency scaling across multiple power domains.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ARM application processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM3715CBPD100 | Includes POWERVR SGX 530 graphics accelerator; otherwise identical pinout, package, and peripheral set | Required for OpenGL ES 1.1/2.0-accelerated UIs; unnecessary if graphics are CPU-rendered or offloaded externally | Select AM3715CBPD100 only when GPU-accelerated rendering is mandatory; AM3703CBPD100 offers cost and power savings where GPU is unused |
| AM3358BZCZ100 | ARM Cortex-A8 at 1 GHz, but on 32nm process; lacks McBSP, has PRU-ICSS instead of full ISP; different pinout and package (324-pin BGA) | Better suited for real-time industrial I/O control; not drop-in compatible due to peripheral and layout differences | AM3358BZCZ100 is a functional alternative for cost-sensitive industrial control, but requires PCB redesign and software adaptation |
Compared with AM3715CBPD100, AM3703CBPD100 removes SGX to reduce cost and power, while retaining identical CPU performance and memory/peripheral interfaces; versus AM3358BZCZ100, it offers richer multimedia peripherals but at higher BOM cost and larger footprint.

FAQ
Does AM3703CBPD100 include an integrated GPU?
No, AM3703CBPD100 does not include the POWERVR SGX graphics accelerator. That feature is exclusive to the AM3715 variant. AM3703CBPD100 relies on CPU-based rendering or external graphics solutions, making it suitable for applications where GPU acceleration is unnecessary - reducing cost and power consumption without compromising application processing capability.
What is the maximum SDRAM capacity supported by AM3703CBPD100?
AM3703CBPD100 supports up to 1 GB of total SDRAM address space via its SDRAM Controller (SDRC), configurable for LPDDR, DDR2, or mobile DDR. The controller includes a memory scheduler (SMS) and rotation engine to optimize bandwidth and reduce latency for concurrent system and graphics memory access.
Is AM3703CBPD100 pin-compatible with AM3715CBPD100?
Yes, AM3703CBPD100 and AM3715CBPD100 share identical 515-pin s-PBGA (CBP) packaging, pin assignment, and electrical characteristics. They are functionally identical except for the presence (AM3715) or absence (AM3703) of the POWERVR SGX graphics block - enabling hardware-compatible board designs with software-selectable GPU usage.
Which operating systems are officially supported on AM3703CBPD100?
Texas Instruments provides validated board support packages (BSPs) for AM3703CBPD100 targeting Linux (including TI's Processor SDK Linux), Android (Gingerbread through Jelly Bean), and Windows Embedded CE.
