Texas Instruments OMAP3503DCBC

Overview

OMAP3503DCBC 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 and digital video cameras requiring integrated display, camera ISP, and USB OTG functionality.

For engineers reviewing the OMAP3503DCBC datasheet, OMAP3503DCBC pinout, OMAP3503DCBC application, or OMAP3503DCBC equivalent, key selection factors include its 515-pin s-PBGA (CBC) package with POP support, discrete memory interface exclusion, and absence of PowerVR SGX graphics-distinguishing it from OMAP3515.

Technical Context

The OMAP3503DCBC implements an in-order, dual-issue, superscalar ARMv7 architecture core with NEON SIMD coprocessor and TrustZone security extensions. It integrates a camera ISP supporting BT.601/BT.656 interfaces, dual 10-bit DACs for composite/S-video output, and a display subsystem with RFBI and RGB interfaces.

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. SmartReflex AVS enables adaptive voltage scaling across 0.985–1.35-V core logic and processor domains.

Key Specifications

Pinout & Package

The OMAP3503DCBC is housed in a 515-pin plastic ball grid array (s-PBGA) package with CBC suffix, featuring 0.65-mm ball pitch on top and 0.5-mm on bottom to support Package-on-Package (POP) memory stacking. Discrete memory interface and GPMC wait pins (gpmc_wait1/2) are not available in this variant.

Equivalent & Alternatives

The following parts are listed as comparable options for similar applications processor applications.

Compared with OMAP3515DCBB, OMAP3503DCBC omits SGX graphics and discrete memory interface to reduce cost and power-making it optimal for cost-sensitive video playback devices. Against i.MX535CJM, OMAP3503DCBC provides native analog video output but lacks eMMC and has lower max frequency.

FAQ

What is the maximum operating frequency of the OMAP3503DCBC?

The OMAP3503DCBC operates at a maximum frequency of 720 MHz. This clock speed is validated under SmartReflex AVS conditions with adaptive core voltage ranging from 0.985 V to 1.35 V. The OMAP3503DCBC datasheet specifies this as the guaranteed performance point for commercial temperature grade operation, and it directly determines real-time video decode latency and UI responsiveness in deployed systems using OMAP3503DCBC.

Does the OMAP3503DCBC include PowerVR SGX graphics acceleration?

No, the OMAP3503DCBC does not include PowerVR SGX graphics acceleration. That feature is exclusive to the OMAP3515 device within the same family. The OMAP3503DCBC shares the same ARM Cortex-A8 core, memory subsystem, and peripheral set-but omits the SGX block entirely, resulting in lower power consumption and cost. Engineers selecting OMAP3503DCBC must implement 2D graphics and UI composition in software or via the display subsystem's hardware layers, not GPU-accelerated OpenGL ES.

What video output interfaces does the OMAP3503DCBC support?

The OMAP3503DCBC supports analog video output via two integrated 10-bit DACs for NTSC/PAL composite and S-video signals, plus digital parallel output through its display subsystem-including 24-bit RGB, RFBI, and BT.656-compatible modes. It does not support HDMI or DVI output natively. The DAC outputs require external passive RC filters per TI design guidelines, and the display subsystem can drive LCD panels up to HD resolution (1280×720) with temporal dithering enabled. All video paths are fully supported in OMAP3503DCBC.

How many general-purpose I/O pins does the OMAP3503DCBC provide?

OMAP3503DCBC provides up to 188 general-purpose I/O pins, as confirmed in the official datasheet Table 1-1 for CBC package. Pin multiplexing restricts concurrent availability-actual usable GPIO count depends on selected peripheral functions (e.g., UART, McSPI, McBSP). Unused pins like gpio_112–gpio_115 and gpio_144–gpio_176 are not available in the CBC variant. Designers must consult the OMAP3503DCBC multiplexing table to allocate pins without conflict.

Is Package-on-Package (POP) memory stacking supported on the OMAP3503DCBC?

Yes, POP memory stacking is supported on the OMAP3503DCBC. Its CBC-package ball map includes dedicated POP interface signals (e.g., pop_a1_a1, pop_b1_b1, pop_k2_m2) documented in Figures 2-3 and 2-4 of the SPRS505H datasheet. This allows vertical integration of LPDDR memory directly atop the processor, reducing PCB area and interconnect inductance. POP is not supported in the CUS package, but is fully functional and production-qualified for OMAP3503DCBC in both commercial and extended temperature grades.
