TMS320DM8148CCYEA0

Digital Signal Processor Dsp Overview

The TMS320DM8148CCYEA0 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 floating-point DSP core running at 750 MHz. The device features 512 KB of L2 cache, 64 KB of RAM, and 48 KB of Boot ROM on the ARM subsystem. Key peripherals include dual DDR2/DDR3 SDRAM interfaces supporting up to DDR3-1066, dual USB 2.0 ports, PCIe 2.0, dual Gigabit Ethernet MACs, and an SGX530 3D graphics engine. It utilizes a 684-pin FCBGA package with a 0.8-mm ball pitch.

Digital Signal Processor Dsp Procurement Notes

Verify the ordering suffix 'CYE' corresponds to the 684-pin FCBGA package with 0.8-mm ball pitch. Confirm the temperature range designation matches industrial requirements (-40°C to +90°C). Ensure compatibility with required DDR3 memory speeds up to 1066 MHz. Check for specific silicon revision differences if upgrading from earlier DM814x variants.

Digital Signal Processor Dsp Selection Notes

Select this model when both high-performance video encoding/decoding and complex 3D graphics are required. The inclusion of the SGX530 engine distinguishes it from the TMS320DM8147, which lacks the graphics core. Ensure the design supports the necessary power domains and voltage levels for the ARM and DSP cores. Verify that the 684-pin BGA footprint fits the target PCB layout constraints.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320DM814x series, which offers software and pin compatibility with the AM387x processors. It serves as an upgrade path for designs requiring higher ARM and DSP performance, scalable to the TMS320DM816x series. The device leverages DaVinci processor technology to combine programmable video/audio processing with rich peripheral sets for multimedia applications.

Digital Signal Processor Dsp Replacement Considerations

The TMS320DM8147 is a compatible alternative if the SGX530 3D graphics engine is not required. For higher performance needs, the TMS320DM816x series provides software-compatible upgrades with faster core speeds.
