Product details
Overview
OMAP3503DCBB from Texas Instruments is a 720-MHz ARM Cortex-A8 applications processor with 256-KB L2 cache, 112-KB ROM, and 64-KB shared SRAM, designed for portable media players, digital video cameras, and web tablets requiring integrated video decode, display processing, and camera interface functionality.
For engineers reviewing the OMAP3503DCBB datasheet, OMAP3503DCBB pinout, OMAP3503DCBB application, or OMAP3503DCBB equivalent, this page delivers verified technical context, package-specific pin mapping (CBB s-PBGA-515), key timing and power specifications, real-world use cases, and validated alternative parts for embedded system design and BOM optimization.
Technical Context
The OMAP3503DCBB implements an in-order, dual-issue, superscalar ARMv7 architecture core with NEON SIMD coprocessor and TrustZone security extensions. It integrates a dedicated Camera ISP supporting BT.601/BT.656 interfaces, dual DACs for composite/S-video output, and a three-layer display subsystem with temporal dithering and rotation.
Its memory subsystem includes SDRAM controller (SDRC) with 16-/32-bit LPDDR support, General Purpose Memory Controller (GPMC) with eight chip-selects, and System DMA with 32 logical channels. Power management leverages SmartReflex AVS for adaptive voltage scaling across 0.985–1.35-V core logic and 1.8-V I/O domains.

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; identical pinout, clock, memory, and peripheral interfaces | Required for OpenGL ES 1.1/2.0 acceleration in gaming or rich UI applications; not needed for pure video playback or control tasks | Select OMAP3515ECBB only when 3D rendering or GPU compute offload is required; OMAP3503DCBB saves cost and power in 2D/media-only designs |
| AM3517BZCNA | Successor device with same ARM Cortex-A8 core, but enhanced USB 2.0 OTG, improved DDR2 interface, and updated power management | Supports newer Linux kernels and longer product lifecycle; lacks POP interface and has different GPMC pin mapping | Choose AM3517BZCNA for new designs needing extended availability and USB 2.0 host support; OMAP3503DCBB remains valid for legacy-compatible or cost-sensitive builds |
Compared with OMAP3515ECBB, OMAP3503DCBB removes SGX graphics to reduce die size and power, making it optimal for cost-constrained media players. Against AM3517BZCNA, it trades modernized USB/DDR for proven stability and POP memory stacking-critical for compact handheld form factors.

FAQ
What is the maximum supported memory configuration for OMAP3503DCBB?
OMAP3503DCBB supports up to 1 GB of total external memory address space via its SDRAM Controller (SDRC) and General Purpose Memory Controller (GPMC). The SDRC interface accommodates 16- or 32-bit LPDDR SDRAM, while GPMC provides glueless access to NOR/NAND Flash, SRAM, and FPGA peripherals - all fully implemented in the CBB package. This memory architecture is documented in SPRS505H Sections 4 and 6.
Does OMAP3503DCBB include a 3D graphics accelerator?
No, OMAP3503DCBB does not include the PowerVR SGX graphics accelerator. That feature is exclusive to the OMAP3515ECBB variant. OMAP3503DCBB retains full video decode, display composition, and 2D acceleration capabilities but omits dedicated 3D rendering hardware - confirmed in SPRS505H Section 1.1 and Functional Block Diagram (Figure 1-1).
What video output standards does OMAP3503DCBB support natively?
OMAP3503DCBB supports NTSC and PAL composite video output natively through its dual 10-bit DACs (tv_out1/tv_out2), along with separate luma/chroma (S-video) output. It also provides parallel RGB (up to 24-bit) and RFBI interfaces for LCD panels. These capabilities are specified in SPRS505H Sections 1.1, 5, and 6.5.
Is OMAP3503DCBB pin-compatible with OMAP3515ECBB?
Yes, OMAP3503DCBB and OMAP3515ECBB share identical pinout, package (CBB s-PBGA-515), electrical characteristics, and peripheral interfaces. The only functional difference is the presence of PowerVR SGX in OMAP3515ECBB. This pin compatibility is explicitly stated in TI's SPRS505H datasheet and validated across all signal assignments in Tables 2-1 and 2-2.
What operating systems are officially supported on OMAP3503DCBB?
OMAP3503DCBB officially supports Linux®, Windows® CE, and Android™ operating systems, as confirmed in SPRS505H Section 1.3. TI provides Board Support Packages (BSPs), kernel drivers, and graphics libraries for all three platforms, with Android support added in the October 2013 revision of the datasheet.
