TMS320DM642AZNZA6 Description

The TMS320DM642AZNZA6 from Texas Instruments is a high-performance fixed-point digital signal processor (DSP) from the TMS320DM64x DaVinci™ series. Designed for demanding embedded applications, it operates at a 600MHz clock rate with a 1.40V core voltage and 3.30V I/O voltage, balancing power efficiency and processing capability. Packaged in a 548-FCBGA (surface-mount), it features 160kB on-chip RAM and relies on external non-volatile memory for program storage. Its interfaces include Host Interface, I2C, McASP, McBSP, and PCI, making it versatile for system integration. While classified as "Not For New Designs," it remains relevant in legacy systems requiring robust DSP performance.

TMS320DM642AZNZA6 Features
