TMS320DM8148CCYE2

Digital Signal Processor Dsp Overview

The TMS320DM8148CCYE2 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 includes a 512KB L2 cache, 64KB RAM, and an SGX530 3D graphics engine delivering up to 25 MPoly/sec. It supports dual DDR2/DDR3 SDRAM interfaces up to DDR3-1066 and provides extensive connectivity via dual Gigabit Ethernet MACs, two USB 2.0 ports, PCIe 2.0, SATA, and HDMI output.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'CCYE2' against the manufacturer's current nomenclature guide, as ordering codes may evolve. Confirm the industrial temperature range (-40°C to +90°C) aligns with system requirements. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Cross-reference the silicon revision (e.g., 3.0 or 2.1) for any known errata affecting power sequencing or clocking configurations.

Digital Signal Processor Dsp Selection Notes

Select this component when both high-level OS control via ARM and intensive media processing via DSP are required on a single chip. The inclusion of the SGX530 graphics engine distinguishes it from the DM8147 variant, which lacks 3D graphics capabilities. Consider the 684-pin BGA package constraints for PCB layout and thermal management. Verify software compatibility if migrating from previous AM38x or DM814x generations.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320DM814x series, which also includes the TMS320DM8147. The primary distinction between the DM8148 and DM8147 is the presence of the SGX530 3D graphics engine in the DM8148. Both share identical core processing units, memory maps, and peripheral sets, allowing for pin-compatible design scalability within the DaVinci platform.

Digital Signal Processor Dsp Replacement Considerations

Publicly confirmed direct substitutes include the TMS320DM8147CCYE2, provided 3D graphics acceleration is not required. For higher performance scaling, the TMS320DM816x series offers increased core speeds but requires software adaptation.
