Product details
Overview
OMAP3525ECUSA from Texas Instruments is a 423-ball s-PBGA applications processor integrating an ARM Cortex-A8 core (up to 720 MHz), C64x+ DSP core (up to 520 MHz), IVA2.2 multimedia accelerator, camera ISP, and display subsystem - all in a single die for portable media and navigation systems requiring high-performance video decode, image processing, and Linux/Android OS support.
For engineers reviewing the OMAP3525ECUSA datasheet, OMAP3525ECUSA pinout, OMAP3525ECUSA application, or OMAP3525ECUSA equivalent, this page delivers verified technical context, package-specific pin mapping, real-world use cases, and validated alternative options - all grounded in TI's SPRS507H datasheet and official package documentation.
Technical Context
The OMAP3525ECUSA implements a heterogeneous dual-core architecture: the ARM Cortex-A8 handles OS execution and application logic with NEON SIMD acceleration, while the dedicated C64x+ DSP offloads real-time video encode/decode, audio processing, and imaging algorithms via the IVA2.2 subsystem. Memory coherency is managed through L3/L4 interconnects linking MPU, DSP, ISP, and display blocks.
It supports discrete memory interfaces only (no POP), features 188 GPIOs with configurable pin muxing, and integrates hardware accelerators for BT.656/BT.601 video capture, S-Video/NTSC/PAL output, and programmable display scaling (1/4× to 4×). Power management uses SmartReflex AVS with adaptive core voltage (0.985–1.35 V) and DVFS.

Equivalent & Alternatives
The following parts are listed as comparable options for similar applications processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OMAP3530ECBB | 515-pin s-PBGA (CBB), includes PowerVR SGX graphics accelerator; supports POP memory stacking. | Required for OpenGL ES 2.0-based 3D UIs (e.g., gaming tablets); not suitable for cost-sensitive CUS-footprint designs. | Select when GPU-accelerated graphics or higher memory bandwidth (via POP) is mandatory - not drop-in compatible with OMAP3525ECUSA PCB. |
| AM3517BZCNA | Pin-compatible 484-ball BGA; ARM Cortex-A8 only (no C64x+ DSP); reduced IVA2.2 feature set (no BT.656, no resize engine). | Suitable for Linux HMI with basic video playback (e.g., industrial HMIs), but lacks real-time DSP offload for audio/video analytics. | Choose for simplified BOM and lower licensing cost where DSP acceleration is unnecessary - requires layout change due to different ball count/pitch. |
Compared with OMAP3530ECBB and AM3517BZCNA, the OMAP3525ECUSA uniquely balances full IVA2.2 multimedia acceleration, 188 GPIO flexibility, and compact 423-ball CUS packaging - making it optimal for portable devices needing rich video I/O without GPU overhead or POP complexity.

FAQ
What is the maximum supported SDRAM capacity for OMAP3525ECUSA?
The OMAP3525ECUSA supports up to 1 GB of total external memory address space via its SDRAM Controller (SDRC) and General Purpose Memory Controller (GPMC). This allows configurations such as 512 MB LPDDR for OS/application runtime and 512 MB NAND for firmware and media storage - fully validated in TI's SPRS507H datasheet Section 6.4.
Does OMAP3525ECUSA include a PowerVR SGX graphics accelerator?
No, the OMAP3525ECUSA does not include the PowerVR SGX graphics accelerator. That feature is exclusive to the OMAP3530 variant (e.g., OMAP3530ECBB). The OMAP3525ECUSA relies on its IVA2.2 subsystem and display processor for video composition and 2D acceleration - sufficient for UI rendering and video playback but not OpenGL ES 2.0 graphics.
Can OMAP3525ECUSA support dual-display output simultaneously?
Yes, OMAP3525ECUSA supports dual-display output via its display subsystem: one panel driven through parallel RGB interface (up to 24-bit HD resolution), and a second via Remote Frame Buffer Interface (RFBI) for secondary LCDs. Both outputs operate concurrently with independent scaling and layer composition - confirmed in Section 1.3 and Figure 1-1 of SPRS507H.
What camera interfaces are supported by OMAP3525ECUSA?
The OMAP3525ECUSA supports parallel digital camera interfaces including BT.601 (8-bit YCbCr 4:2:2), BT.656 (10-bit YCbCr 4:2:2), and raw RGB/RGB Bayer formats - with dedicated pins (cam_d0–cam_d11, cam_pclk, cam_hs, cam_vs) and integrated ISP for auto-exposure and white balance. MIPI CSI-2 is not supported.
Is OMAP3525ECUSA pin-compatible with OMAP3530ECBB?
No, OMAP3525ECUSA (423-ball CUS package) is not pin-compatible with OMAP3530ECBB (515-ball CBB package). They differ in ball count, pitch (0.65 mm vs. 0.5/0.4 mm), pin assignment, and feature availability (e.g., POP interface, SGX GPU). Migration requires PCB redesign - confirmed in Table 1-1 of SPRS507H.
