Texas Instruments OMAP3503ECUS72

Overview

OMAP3503ECUS72 from Texas Instruments is a 720-MHz ARM Cortex-A8 applications processor in a 423-pin s-PBGA (CUS) package, featuring 256-KB L2 cache, 112-KB ROM, 64-KB shared SRAM, and integrated display subsystem supporting HD resolution, camera ISP, and dual LCD panels - deployed in portable media players and digital video cameras.

For engineers reviewing the OMAP3503ECUS72 datasheet, OMAP3503ECUS72 pinout, OMAP3503ECUS72 application, or OMAP3503ECUS72 equivalent, key selection considerations include its CUS-package–specific GPIO count (188 pins), absence of POP interface and discrete memory interface, SDRC/GPMC memory controller support, and SmartReflex-enabled adaptive voltage scaling for mobile power optimization.

Technical Context

The OMAP3503ECUS72 implements an in-order, dual-issue, superscalar ARMv7 architecture core with NEON SIMD coprocessor and TrustZone security extensions. Its MPU subsystem integrates a 16-KB/16-KB L1 instruction/data cache and MMU enhancements enabling Linux, Android, and Windows CE execution.

Unlike the OMAP3515, it omits the PowerVR SGX graphics accelerator. It retains full camera ISP (CCD/CMOS, BT.601/BT.656), display subsystem (RGB, RFBI, NTSC/PAL DACs), and serial interfaces including five McBSPs, four McSPI ports, three UARTs (one with IrDA/CIR), and three I²C controllers - all mapped to the 423-ball CUS package pinout.

Key Specifications

Pinout & Package

OMAP3503ECUS72 uses a 423-pin s-PBGA package (CUS suffix) with 0.65-mm ball pitch, no POP interface, and no discrete memory interface - distinguishing it from CBB/CBC variants. Ball assignments follow TI SPRS505H Figure 2-5 and Table 2-3.

FAQ

What is the maximum operating frequency of the OMAP3503ECUS72?

The OMAP3503ECUS72 operates at a maximum guaranteed frequency of 720 MHz under commercial temperature conditions. This rating is validated per TI SPRS505H Section 3.3 and applies to the CUS-package variant across its specified voltage range (0.985 V to 1.35 V core). The OMAP3503ECUS72 achieves this frequency using adaptive voltage scaling via SmartReflex, and actual sustained clock depends on thermal design and power delivery stability.

Does the OMAP3503ECUS72 include a PowerVR SGX graphics accelerator?

No, the OMAP3503ECUS72 does not include the PowerVR SGX graphics accelerator. That feature is exclusive to the OMAP3515 device variant. The OMAP3503ECUS72 retains full video processing capability - including display subsystem, camera ISP, and dual DACs - but relies on CPU and NEON for graphics rendering. This makes OMAP3503ECUS72 suitable for applications requiring video playback and UI composition without heavy 3D graphics workloads.

What memory interfaces are supported by the OMAP3503ECUS72?

The OMAP3503ECUS72 supports two primary memory interfaces: the SDRAM Controller (SDRC) for LPDDR SDRAM and the General Purpose Memory Controller (GPMC) for NAND/NOR flash, SRAM, and FPGA interfacing. Notably, the CUS package omits the discrete memory interface and POP interface found in CBB/CBC packages. GPMC provides eight chip-selects and flexible asynchronous protocol control, while SDRC supports 16-/32-bit data buses and up to 1 GB total address space - confirmed in SPRS505H Sections 1.1 and 6.4.

How many GPIO pins are available on the OMAP3503ECUS72?

Up to 188 general-purpose I/O pins are supported on the OMAP3503ECUS72, as documented in TI SPRS505H Table 1-1. However, pin multiplexing restricts the number simultaneously usable - actual count depends on active peripheral selections (e.g., enabling UART1 disables certain GPIO functions). The CUS package provides full access to all 188 GPIOs, unlike CBB which sacrifices 16 GPIOs, and pin assignments are defined in Table 2-3 and Figures 2-5 through 2-9 of the datasheet.

What video output standards does the OMAP3503ECUS72 support?

The OMAP3503ECUS72 supports NTSC and PAL composite video output via two integrated 10-bit digital-to-analog converters (DACs), as specified in SPRS505H Sections 1.1 and 5.2. It also provides parallel RGB (up to 24-bit) and RFBI interfaces for direct LCD panel drive. The DACs support luma/chroma separate (S-video) and combined (composite) outputs, with programmable gain and filtering - enabling analog video output without external encoders in portable media and navigation devices.
