Product details
Overview
OMAP3503ECBC from Texas Instruments is a high-performance applications processor based on the ARM Cortex-A8 core operating at up to 720 MHz, integrating 256-KB L2 cache, 112-KB ROM, and 64-KB shared SRAM. It supports Linux®, Android™, and Windows® CE, and targets portable media players, digital video cameras, and web tablets requiring integrated video processing, camera ISP, and display subsystems.
For engineers reviewing the OMAP3503ECBC datasheet, OMAP3503ECBC pinout, OMAP3503ECBC application, or OMAP3503ECBC equivalent, key selection criteria include its 515-pin s-PBGA (CBC) package with POP support, discrete memory interface exclusion, absence of PowerVR SGX graphics (distinguishing it from OMAP3515), and confirmed 188 GPIO capability with specific multiplexing constraints per Table 1-1.
Technical Context
The OMAP3503ECBC implements the OMAP™3 architecture with an in-order, dual-issue, superscalar ARM Cortex-A8 microprocessor core compliant with ARMv7, including TrustZone® security extensions, Thumb®-2 instruction set, and NEON™ SIMD coprocessor for multimedia acceleration. Its memory subsystem includes SDRAM Controller (SDRC) supporting LPDDR, General Purpose Memory Controller (GPMC) with eight chip-select pins, and SmartReflex™ technology enabling dynamic voltage and frequency scaling (DVFS).
Unlike the OMAP3515, the OMAP3503ECBC omits the PowerVR SGX graphics accelerator but retains full camera ISP (CCD/CMOS interface, BT.601/BT.656 support), dual-display subsystem (RGB + RFBI), video DACs for NTSC/PAL output, and comprehensive serial interfaces 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; uses CBB package with discrete memory interface and different pin muxing | Required for OpenGL ES 2.0-based UI rendering or 3D gaming; not drop-in compatible due to package and GPMC signal differences | Select when 3D graphics acceleration is mandatory and PCB layout accommodates CBB package and memory interface routing |
| i.MX535CJM | ARM Cortex-A8 @ 1 GHz, Vivante GC320 GPU, different memory controller (DDR2/DDR3), no integrated video DACs | Suitable for displays requiring LVDS or HDMI output; requires external DAC for analog video; lacks BT.656 camera interface | Choose for higher CPU clock speed and modern DDR3 support where analog video output is unnecessary and camera interface flexibility is lower priority |
Compared with OMAP3515ECBB, OMAP3503ECBC trades 3D graphics capability for lower cost and power, while i.MX535CJM offers higher clock speed and DDR3 support but requires external components for analog video and lacks native BT.656 camera support-making OMAP3503ECBC optimal for cost-sensitive, analog-video-centric embedded media devices.

FAQ
What distinguishes OMAP3503ECBC from OMAP3515?
The OMAP3503ECBC excludes the PowerVR SGX graphics accelerator present in OMAP3515, making it a cost- and power-optimized variant for applications that do not require OpenGL ES 2.0 or OpenVG acceleration. Both share identical ARM Cortex-A8 core, memory subsystems, camera ISP, and display features-but OMAP3503ECBC is strictly intended for 2D/UI and video-centric use cases without 3D rendering demands.
Does OMAP3503ECBC support Android OS?
Yes, OMAP3503ECBC supports Android™ as confirmed in the SPRS505H datasheet revision history (October 2013). It provides the necessary ARMv7 compliance, NEON SIMD acceleration, memory bandwidth, and peripheral drivers required for Android 2.x–4.x platform integration, including hardware-accelerated video decode and camera preview pipelines.
What video output interfaces does OMAP3503ECBC provide?
OMAP3503ECBC integrates two 10-bit digital-to-analog converters (DACs) supporting composite NTSC and PAL output, plus separate luma/chroma (S-video) signals. It also provides a 24-bit parallel RGB digital output and Remote Frame Buffer Interface (RFBI) for direct LCD panel driving-enabling simultaneous analog and digital video output without external encoders.
Is the OMAP3503ECBC pin-compatible with OMAP3503ECBB?
No, OMAP3503ECBC is not pin-compatible with OMAP3503ECBB. While both are 515-pin s-PBGA packages, the CBC and CBB variants differ in ball pitch (0.65/0.5 mm vs 0.5/0.4 mm), POP interface layer alignment, and signal assignment-particularly for GPMC wait/ncs pins and UART control signal muxing. PCB redesign is required for substitution.
What camera sensor interfaces does OMAP3503ECBC support?
OMAP3503ECBC supports parallel CCD and CMOS image sensors via its dedicated Camera ISP interface, including BT.601 (8-bit) and BT.656 (10-bit) YCbCr 4:2:2 digital video standards. It provides 12-bit data bus (cam_d0–cam_d11), pixel clock (cam_pclk), horizontal/vertical sync (cam_hs/cam_vs), and field signal (cam_fld) for direct sensor connection without bridge logic.
