替换日期 TMS320C6727B– 器件与被比较器件具有相似功能,但并不功能等效。

TI does not recommend using this part in a new design. This product continues to be in production to support existing customers.

描述

The '320C40 digital signal processors (DSPs) are 32-bit, floating-point processors manufactured in 0.72-um, double-level metal CMOS technology. The '320C40 is a part of the fourth generation of DSPs from Texas Instruments and is designed primarily for parallel processing.
