OMAP3530DCUSA

OMAP3530DCUSA is TI’s OMAP3530 system-on-chip, part of the OMAP3 family, designed for multimedia mobile devices. It combines an ARM Cortex-A8 application processor with a TI DSP (C64x+) and dedicated imaging/video accelerators, enabling smooth video playback, camera processing, and graphics. The SoC includes an integrated memory controller, peripherals (USB, LCD/camera interfaces), and power-management features for battery-powered devices. It supports multimedia codecs and 2D/3D graphics acceleration, making it suitable for smartphones, PDAs, and other portable devices from the late 2000s. DCUSA likely denotes a specific package/variant used by a vendor or reference design; consult TI’s datasheet or device documentation for exact features, pinout, and clocking. In short: a high-performance, multimedia-oriented mobile SoC from TI designed to run mobile OSes with efficient power usage.

There isn’t an exact external substitute with the same package/pinout. The closest equivalents are other OMAP3 Cortex-A8 parts from TI, e.g. OMAP3430, OMAP3515, and OMAP3525 (similar CPU/peripherals). Differences lie in memory interface and peripherals. For exact cross-reference, check TI’s cross-reference data or distributor listings for the OMAP3530DCUSA family variant.

OMAP3530DCUSA (OMAP3530) is a multimedia-enabled application processor. Common application areas include:
- Smartphones and mobile Internet devices
- Portable media players and handheld gaming
- Automotive infotainment and navigation systems
- Set-top boxes, IPTV/digital TV and home media hubs
- Embedded consumer electronics (digital cameras, camcorders, dashcams)
- Industrial/medical embedded systems and development platforms (e.g., BeagleBoard)
Its ARM Cortex-A8 core plus integrated multimedia processing enable rich video, audio, camera and graphics features for these domains.

It’s a BGA (ball-grid array) package — the OMAP3530DCUSA variant uses an FBGA-style package.
