TMS320DM8148BCYE1

Digital Signal Processor Dsp Overview

The TMS320DM8148BCYE1 is a high-performance System-on-Chip (SoC) from the TMS320DM814x DaVinci video processor family, manufactured by Texas Instruments. It integrates an ARM Cortex-A8 RISC core operating up to 1 GHz and a C674x VLIW DSP core running at 750 MHz. The device features a 684-pin FCBGA package with a 0.8-mm ball pitch. Key hardware components include a 512KB L2 cache for the ARM core, 256KB L2 RAM for the DSP, an SGX530 3D graphics engine, and a High-Definition Video Image Coprocessor (HDVICP v2). It supports dual DDR2/DDR3 SDRAM interfaces and includes extensive connectivity options such as dual Gigabit Ethernet MACs, two USB 2.0 ports, PCIe 2.0, and SATA.

Digital Signal Processor Dsp Feature Summary

• Video Surveillance DVRs and IP Network Cameras (Netcam)
• Digital Signage systems
• Media Players and Adapters
• Mobile Medical Imaging devices

Digital Signal Processor Dsp Procurement Notes

Verify the ordering suffix 'B' against the manufacturer's current nomenclature guide to confirm specific temperature range or silicon revision details. Ensure compatibility with required DDR2/DDR3 memory configurations and power supply sequencing (OPP100, OPP120, OPP166) during system design. Confirm that the 684-pin FCBGA package constraints align with PCB layout capabilities.

Digital Signal Processor Dsp Selection Notes

Select this model when both high-performance general-purpose computing (ARM Cortex-A8) and intensive digital signal processing (C674x DSP) are required in a single chip. The inclusion of the SGX530 graphics engine distinguishes it from lower-end variants like the DM8147. Ensure the application requires the specific pin count and I/O density provided by the CYE package for interfacing with multiple video capture/display modules and storage controllers.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320DM814x DaVinci family, which shares software and pin compatibility with the AM387x series. It serves as an upgrade path for designs using AM387x processors by adding the C674x DSP core and video codec hardware. Higher-performance software-compatible alternatives within the same ecosystem include the AM389x and TMS320DM816x.

Digital Signal Processor Dsp Replacement Considerations

The TMS320DM8147 is a pin-compatible alternative within the same datasheet but lacks the SGX530 3D graphics engine. For designs requiring higher clock speeds, the TMS320DM816x offers software compatibility with increased ARM and DSP performance.
