Texas Instruments DM3725CBC

Overview

DM3725CBC from Texas Instruments is a 45-nm digital media processor integrating an ARM Cortex-A8 core (up to 1 GHz), TMS320C64x+ DSP core (up to 800 MHz), and IVA2.2 video acceleration subsystem. It delivers high-performance multimedia processing for portable terminals, navigation systems, and industrial HMIs while supporting Linux and Windows Embedded CE. Key confirmed parameters include 256KB L2 cache, 32KB L1 instruction + 32KB L1 data cache, and 515-pin s-PBGA package with 0.65mm top / 0.5mm bottom ball pitch.

For engineers reviewing the DM3725CBC datasheet, DM3725CBC pinout, DM3725CBC application, or DM3725CBC equivalent, this page provides verified technical context on its dual-core architecture, memory subsystem configuration, power management via SmartReflex™, and interface support including SDRC, GPMC, McSPI, McBSP, USB OTG/Host, and HDQ/1-Wire - all critical for embedded media system design and migration planning.

Technical Context

The DM3725CBC implements a heterogeneous dual-core architecture: the ARM Cortex-A8 core executes HLOS tasks with TrustZone® security and NEON™ SIMD acceleration, while the C64x+ DSP handles real-time signal processing in imaging, audio, and video pipelines. Its IVA2.2 subsystem offloads encode/decode operations for MPEG-4, H.264, and VC-1.

Memory hierarchy includes dedicated L1P/L1D caches (32KB each), unified 256KB L2 cache, 64KB on-chip RAM, and 32KB ROM. Power delivery uses multiple voltage domains (vdd_core, vdd_mpu_iva, vdds_mem) managed by SmartReflex™ AVS for dynamic voltage/frequency scaling across OPPs.

Key Specifications

Pinout & Package

The DM3725CBC is housed in a 515-ball s-PBGA package (CBC suffix) with 0.65mm ball pitch on top and 0.5mm on bottom. Pin assignments are defined across four quadrants (A–D), with multiplexed functions including SDRC, GPMC, McSPI, McBSP, USB, UART, I²C, HDQ, and GPIO. Ball-level terminal descriptions are fully documented in TI SPRS685D Rev. July 2011, Sections 2.1–2.2.

FAQ

What is the maximum operating frequency of the ARM Cortex-A8 core in the DM3725CBC?

The DM3725CBC supports an ARM Cortex-A8 core operating at up to 1 GHz under commercial temperature conditions. This frequency is achievable with appropriate thermal design and SmartReflex™-managed voltage scaling (OPP5). Lower OPPs (e.g., OPP3 at 600 MHz) are available for reduced power consumption in thermally constrained applications. The DM3725CBC datasheet (SPRS685D) specifies these performance points with corresponding voltage and timing requirements.

Does the DM3725CBC include a graphics processing unit (GPU)?

No, the DM3725CBC does not include a GPU. Unlike the DM3730CBC, which integrates the POWERVR SGX530 graphics accelerator, the DM3725CBC omits GPU logic entirely. This makes it suitable for applications requiring high-performance video processing (via IVA2.2) and general-purpose computing (via ARM+DSP) without 3D graphics rendering needs. The absence of GPU reduces silicon area, power consumption, and software driver complexity.

How many general-purpose I/O pins does the DM3725CBC provide?

The DM3725CBC provides up to 188 general-purpose I/O pins, multiplexed with other peripheral functions such as UART, I²C, McSPI, McBSP, and USB. These pins are distributed across the 515-ball s-PBGA package and support configurable pull-up/down, drive strength, and slew rate. Pin functionality is selected via register-controlled pad configuration, allowing flexible hardware reuse across different product variants without PCB redesign.

What memory interfaces are supported by the DM3725CBC?

The DM3725CBC supports three primary memory interfaces: (1) SDRC for 16-/32-bit LPDDR/DDR SDRAM with SMS rotation engine; (2) GPMC for NOR/NAND flash, SRAM, and pseudo-SRAM with ECC support; and (3) on-chip 64KB RAM + 32KB ROM. These interfaces operate independently, enabling concurrent access-for example, SDRAM for video frame buffers, NAND for firmware storage, and on-chip RAM for real-time DSP code execution-without bus contention.

Is the DM3725CBC pin-compatible with the DM3730CBC?

Yes, the DM3725CBC and DM3730CBC share identical 515-pin s-PBGA package dimensions, ball pitch, and pinout mapping. They are mechanically and electrically pin-compatible, allowing PCB reuse between the two variants. The key difference lies in internal silicon: DM3730CBC includes POWERVR SGX530 GPU logic, while DM3725CBC excludes it. Firmware and driver stacks must be adapted accordingly, but no hardware changes are required for migration.
