Product details
Overview
OMAP3503ECUS from Texas Instruments is a 423-pin s-PBGA applications processor based on the ARM Cortex-A8 core, operating up to 720 MHz with 256-KB L2 cache, 112-KB ROM, and 64-KB shared SRAM. It integrates camera ISP, display subsystem, multiple serial interfaces (UART, McSPI, McBSP), and supports Linux, Android, and Windows CE - deployed in portable media players and digital video cameras.
For engineers reviewing the OMAP3503ECUS datasheet, OMAP3503ECUS pinout, OMAP3503ECUS application, or OMAP3503ECUS equivalent, key selection considerations include its CUS-package limitations (no POP interface, no discrete memory interface, reduced GPMC chip-selects), absence of PowerVR SGX graphics, and confirmed support for SmartReflex AVS, HDQ/1-Wire, and dual DAC video output.
Technical Context
The OMAP3503ECUS implements an ARMv7-compliant Cortex-A8 superscalar core with NEON SIMD coprocessor, Thumb-2 instruction set, TrustZone security, and dynamic branch prediction. Its memory subsystem includes SDRAM controller (SDRC) supporting LPDDR, General Purpose Memory Controller (GPMC) with eight chip-selects (though gpmc_ncs1/ncs2 and wait1/wait2 are omitted in CUS), and system DMA with 32 logical channels.
Unlike the OMAP3515, the OMAP3503ECUS excludes the PowerVR SGX graphics accelerator and associated tile-based rendering pipeline. It retains full camera ISP (CCD/CMOS, BT.601/BT.656), display subsystem (dual LCD, RFBI, NTSC/PAL DAC outputs), and serial peripherals including five McBSPs (two with sidetone), four McSPI ports, three UARTs, and three I²C controllers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar applications processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OMAP3515ECBB | Includes PowerVR SGX 3D graphics accelerator; 515-pin CBB package with POP interface and full GPMC (8 chip-selects, 4 wait pins) | Required for OpenGL ES 2.0 graphics rendering, 3D UI, or GPU-accelerated video post-processing | Select when 3D graphics, memory stacking, or expanded external memory interfacing is required - not drop-in compatible due to package and pinout differences |
| OMAP3503ECBC | Same core and peripherals as OMAP3503ECUS but in 515-pin CBC package with discrete memory interface and POP support | Enables higher-density memory configurations and FPGA/ASIC glueless interfacing via GPMC | Choose for designs needing expanded memory bandwidth or external logic interfacing - requires PCB redesign due to larger package and different ball map |
Compared with OMAP3515ECBB and OMAP3503ECBC, the OMAP3503ECUS trades graphics acceleration and memory interface flexibility for compact 423-pin packaging and lower system cost - ideal for cost-sensitive, analog-video-focused embedded applications where 3D rendering is unnecessary.

FAQ
Does OMAP3503ECUS include PowerVR SGX graphics?
No. The OMAP3503ECUS does not integrate the PowerVR SGX graphics accelerator - that feature is exclusive to the OMAP3515 variant. OMAP3503ECUS relies on CPU-based rendering or optional external GPUs. This omission reduces die size, power consumption, and cost while retaining full video decode, display, and camera capabilities essential for its target applications.
What are the key package limitations of OMAP3503ECUS compared to CBB/CBC variants?
The OMAP3503ECUS in the CUS package lacks Package-on-Package (POP) interface support, discrete memory interface capability, and two GPMC chip-selects (gpmc_ncs1, gpmc_ncs2) plus two wait pins (gpmc_wait1, gpmc_wait2). These omissions reduce board area and complexity but limit memory stacking and external logic interfacing options available in the 515-pin CBB/CBC packages.
Which operating systems are officially supported on OMAP3503ECUS?
OMAP3503ECUS supports Linux®, Android™, and Windows® CE out-of-the-box, with validated BSPs and driver stacks provided by Texas Instruments. Android support was added in the October 2013 revision (SPRS505H), confirming compatibility with early Android versions optimized for ARM Cortex-A8 platforms.
Can OMAP3503ECUS drive dual displays simultaneously?
Yes. The OMAP3503ECUS display subsystem supports dual LCD panels concurrently via its programmable parallel output and RFBI interface. It can drive one panel using RGB24 and another via RFBI, enabling split-screen UIs or independent video and graphics layers - confirmed in the functional block diagram and Section 1.3 description.
What video output interfaces does OMAP3503ECUS provide?
OMAP3503ECUS provides two 10-bit DACs supporting composite NTSC and PAL, S-Video (luma/chroma), and CVBS outputs. It also offers parallel digital RGB24, YUV, and RFBI interfaces. No HDMI or DVI is integrated - those require external PHYs or bridge ICs, as stated in the "Display Subsystem" section of SPRS505H.
