Product details
Overview
OMAP3503DCUSA from Texas Instruments is a 720-MHz ARM Cortex-A8 applications processor in a 423-pin s-PBGA package (CUS suffix), featuring 256-KB L2 cache, 112-KB ROM, 64-KB shared SRAM, and integrated camera ISP, display subsystem, and multimedia interfaces - deployed in portable media players and digital video cameras.
For engineers reviewing the OMAP3503DCUSA datasheet, OMAP3503DCUSA pinout, OMAP3503DCUSA application, or OMAP3503DCUSA equivalent, key selection criteria include its CUS-package GPIO count (188 pins, with muxing constraints), absence of POP interface and discrete memory interface, dual DAC support for NTSC/PAL output, and SmartReflex-enabled adaptive voltage scaling for mobile power optimization.
Technical Context
The OMAP3503DCUSA implements an in-order, dual-issue, superscalar ARMv7 architecture core with NEON SIMD coprocessor and TrustZone security extensions. Its memory subsystem includes SDRAM controller (SDRC) supporting LPDDR, GPMC for NAND/NOR/SRAM, and SMS rotation engine - all connected via hierarchical L3/L4 interconnects.
Unlike the OMAP3515, the OMAP3503DCUSA omits the PowerVR SGX graphics accelerator and associated tile-based rendering pipeline. It retains full camera ISP functionality (CCD/CMOS input, BT.601/BT.656, resize engine), dual 10-bit DACs for composite video, and RFBI LCD panel support up to HD resolution.

Equivalent & Alternatives
The following parts are listed as comparable options for similar applications processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OMAP3515CBB | Includes PowerVR SGX graphics accelerator; 515-pin CBB package with POP interface and discrete memory support. | Required for OpenGL ES 2.0-accelerated UIs or 3D gaming; not suitable for cost-sensitive CUS-footprint designs. | Select OMAP3515CBB only when GPU acceleration is mandatory and PCB redesign for larger package is acceptable. |
| i.MX535 | Vybrid dual-core ARM Cortex-A8; lacks integrated video DACs but adds VPU for H.264 HP decode; 45 nm process vs. OMAP3503's 65 nm. | Better suited for high-definition video analytics; requires external DAC for analog video output. | Choose i.MX535 for higher video throughput or lower power-per-MIPS; retain OMAP3503DCUSA when analog video output and legacy software compatibility are priorities. |
Compared with OMAP3515CBB and i.MX535, the OMAP3503DCUSA delivers optimal balance of multimedia capability, analog video integration, and compact 423-pin footprint - making it ideal for cost-constrained portable devices where GPU acceleration is unnecessary but NTSC/PAL output is required.

FAQ
What is the maximum operating frequency of the OMAP3503DCUSA?
The OMAP3503DCUSA operates at up to 720 MHz on its ARM Cortex-A8 core. This frequency is validated under commercial temperature conditions (0°C to 90°C) with SmartReflex AVS enabled and 1.2 V core supply. The device supports multiple OPP (Operating Performance Points) ranging from OPP100 (720 MHz) down to OPP20 (120 MHz) for dynamic power scaling.
Does the OMAP3503DCUSA include a PowerVR SGX graphics accelerator?
No, the OMAP3503DCUSA does not include the PowerVR SGX graphics accelerator. That feature is exclusive to the OMAP3515 variant. The OMAP3503DCUSA retains full CPU, ISP, display, and multimedia subsystems but omits the 3D graphics engine - confirmed in TI SPRS505H Section 1.3 and functional block diagram.
What video output interfaces does the OMAP3503DCUSA support?
The OMAP3503DCUSA supports analog video output via two integrated 10-bit DACs for NTSC and PAL composite signals, plus S-video (luma/chroma separate). It also provides parallel digital RGB/YUV output (up to 24-bit) and RFBI interface for Sharp/BOE LCD panels - all documented in Sections 1.1, 5, and 6.5 of the SPRS505H datasheet.
Is the OMAP3503DCUSA pin-compatible with the OMAP3515CBB package?
No, the OMAP3503DCUSA (423-pin CUS package) is not pin-compatible with OMAP3515CBB (515-pin CBB package). They differ in ball count, pitch (0.65 mm vs. 0.5/0.4 mm), signal mapping, and feature availability (e.g., POP, GPMC wait pins, McSPI CS lines). Migration requires full PCB redesign and layout validation per TI's Table 1-1.
What operating systems are officially supported on the OMAP3503DCUSA?
Texas Instruments officially supports Linux®, Windows® CE, and Android™ on the OMAP3503DCUSA. Android support was added in the October 2013 revision of SPRS505H. Board support packages (BSPs), kernel patches, and graphics drivers are provided through TI's Processor SDK and legacy EZSDK releases.
