Texas Instruments OMAP3515DCBC

Overview

OMAP3515DCBC 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, NTSC/PAL video output, and dual LCD panels. It targets portable media players, digital video cameras, and web tablets requiring high-performance multimedia processing.

For engineers reviewing the OMAP3515DCBC datasheet, OMAP3515DCBC pinout, OMAP3515DCBC application, or OMAP3515DCBC equivalent, key selection factors include its 515-pin s-PBGA (CBC) package with POP support, discrete memory interface exclusion, 188 GPIOs, and SmartReflex-enabled adaptive voltage scaling for mobile power optimization.

Technical Context

The OMAP3515DCBC implements an in-order, dual-issue, superscalar ARMv7 architecture core 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 PowerVR SGX graphics engine delivers up to 10 MPoly/sec with OpenGLES 2.0 and OpenVG 1.0 API support.

It features a hierarchical L3/L4 interconnect fabric enabling concurrent access to SDRAM controller (SDRC), General Purpose Memory Controller (GPMC), Camera ISP, Display Subsystem, and multiple serial interfaces-including five McBSPs (two with Sidetone), four McSPI ports, three UARTs (one IrDA/CIR-capable), and dual USB 2.0 OTG/Host subsystems with ULPI/TLL support.

Key Specifications

Pinout & Package

OMAP3515DCBC uses a 515-pin s-PBGA package (CBC suffix) with 0.65-mm ball pitch on top and 0.5-mm on bottom, supporting Package-on-Package (POP) memory stacking but excluding discrete memory interface signals (gpmc_ncs1/ncs2, gpmc_wait1/wait2). Total I/O count is 188 GPIOs, with pin multiplexing governed by Table 2-2 in SPRS505H.

FAQ

What is the maximum supported SDRAM capacity for OMAP3515DCBC?

The OMAP3515DCBC supports up to 1 GB of total address space via its SDRAM Controller (SDRC), accommodating configurations such as 256-MB × 4 banks or 512-MB × 2 banks of LPDDR/DDR2 memory. This capacity is sufficient for Android 2.x–4.x deployments with framebuffer, application heap, and kernel memory requirements. The SDRC implements automatic refresh and configurable burst lengths to meet JEDEC timing specifications.

Does OMAP3515DCBC support Android operating system?

Yes, OMAP3515DCBC is officially supported by Texas Instruments for Android versions up to 4.0 (Ice Cream Sandwich), with validated BSPs, kernel drivers, and graphics HALs. The device's ARM Cortex-A8 core, PowerVR SGX GPU, and integrated display subsystem provide the necessary compute, rendering, and output capabilities required for responsive Android UIs and multimedia apps.

How does SmartReflex technology function in OMAP3515DCBC?

SmartReflex in OMAP3515DCBC uses on-die process/voltage/temperature (PVT) sensors to dynamically adjust the adaptive core voltage (0.985–1.35 V) in real time, independent of frequency scaling. This reduces active power consumption by up to 40% compared to fixed-voltage operation, without compromising performance-critical for extending battery life in portable media players and tablets using OMAP3515DCBC.

What video output interfaces are integrated into OMAP3515DCBC?

OMAP3515DCBC integrates parallel digital RGB (up to 24-bit), RFBI, and analog composite video outputs. It includes two 10-bit DACs supporting NTSC and PAL standards, with dedicated pins (tv_out1/tv_out2, tv_vref, tv_vfb1/vfb2) for direct connection to TV encoders or passive filters. No external video encoder IC is required for basic CVBS/S-Video output.

Is OMAP3515DCBC pin-compatible with OMAP3503DCBC?

Yes, OMAP3515DCBC and OMAP3503DCBC share identical 515-pin s-PBGA (CBC) package dimensions, ball pitch, and pinout mapping. They differ functionally-OMAP3515DCBC includes PowerVR SGX graphics and full display subsystem features, while OMAP3503DCBC omits SGX and has reduced display capabilities-but mechanical and electrical interface compatibility is maintained for drop-in replacement in non-graphics use cases.
