Texas Instruments OMAP3515ECUS

Overview

OMAP3515ECUS from Texas Instruments is a 720-MHz ARM Cortex-A8 applications processor with PowerVR SGX graphics acceleration, 256-KB L2 cache, and integrated display subsystem supporting HD resolution and dual LCD panels. It features 188 GPIO pins, dual 10-bit DACs for composite NTSC/PAL video output, and camera ISP supporting BT.601/BT.656 interfaces - deployed in portable media players and digital video cameras.

For engineers reviewing the OMAP3515ECUS datasheet, OMAP3515ECUS pinout, OMAP3515ECUS application, or OMAP3515ECUS equivalent, key selection criteria include its 423-pin s-PBGA (CUS) package constraints (no POP interface, no discrete memory interface), SmartReflex DVFS support, and absence of HSUSB3_TLL/MM_FSUSB3 functionality compared to CBB/CBC variants.

Technical Context

The OMAP3515ECUS implements an in-order, dual-issue, superscalar ARMv7 architecture with NEON SIMD coprocessor and TrustZone security extensions. Its MPU subsystem integrates 16-KB/16-KB L1 instruction/data caches and a 256-KB unified L2 cache, while the display subsystem delivers parallel RGB output up to 24-bit depth and supports temporal dithering and 3-layer composition.

It includes a dedicated Camera ISP with CCD/CMOS sensor interface, BT.601 (8-bit) and BT.656 (10-bit) YCbCr 4:2:2 support, and hardware resize engine (1/4× to 4×). The device uses a hierarchical L3/L4 interconnect fabric and supports dynamic voltage/frequency scaling via two SmartReflex control modules.

Key Specifications

Pinout & Package

OMAP3515ECUS uses a 423-ball s-PBGA package (CUS suffix) with 0.65-mm ball pitch. Unlike CBB/CBC variants, it omits POP interface, discrete memory interface, HSUSB3_TLL, and MM_FSUSB3 functionality. Pin assignments follow quadrant-based top-view layout per TI SPRS505H Section 2.2.1, with critical interfaces including SDRC (SDRAM controller), GPMC (general-purpose memory), DSS (display subsystem), and ISP (camera interface).

FAQ

What is the maximum operating frequency of the OMAP3515ECUS?

The OMAP3515ECUS operates at up to 720 MHz on its ARM Cortex-A8 core. This frequency is validated under commercial temperature grade conditions and supports real-time multimedia processing, including 720p video decode and Android UI rendering. The actual sustained frequency depends on thermal design, power delivery stability, and SmartReflex voltage scaling configuration - all specified in TI's SPRS505H datasheet sections 3.3 and 4.2.

Does the OMAP3515ECUS support HDMI output?

No, the OMAP3515ECUS does not support HDMI output. It provides analog video output only via two integrated 10-bit DACs for composite NTSC/PAL and S-Video signals. For HDMI capability, TI offers the OMAP3530ECUS variant, which replaces the DACs with an integrated HDMI transmitter while retaining the same 423-pin CUS package footprint.

What memory interfaces are supported by the OMAP3515ECUS?

The OMAP3515ECUS supports SDRAM via its SDRC (SDRAM Controller) with LPDDR/SDR compatibility, and asynchronous memory via GPMC (General Purpose Memory Controller) for NOR/NAND flash, SRAM, and FPGA interfacing. It does not support discrete memory interface or POP stacking - features excluded in the CUS package per Table 1-1 of SPRS505H.

How many general-purpose I/O pins does the OMAP3515ECUS provide?

OMAP3515ECUS provides up to 188 GPIO pins, though pin muxing restricts simultaneous availability. All GPIOs are multiplexed with other functions (e.g., UART, McBSP, McSPI), and exact count depends on selected peripheral configurations. Table 2-4 in SPRS505H documents CUS-specific multiplexing characteristics and GPIO availability constraints.

Is the PowerVR SGX graphics accelerator included in OMAP3515ECUS?

Yes, the OMAP3515ECUS includes the PowerVR SGX graphics accelerator, delivering up to 10 MPoly/sec and supporting OpenGL ES 1.1/2.0 and OpenVG 1.0 APIs. This GPU is functionally identical to that in OMAP3503 and OMAP3525, enabling hardware-accelerated UI rendering and 2D/3D graphics without CPU intervention - confirmed in Section 1.1 and Figure 1-1 of SPRS505H.
