64-bit RISC microprocessor: TMPR4956CXBG-400
64-bit RISC microprocessor that can easily be enhanced with desired functions
The TMPR4956CXBG is equipped with a TX49/H4 core that uses a 90-nm process to enable 400 MHz operation. These processors have a built-in floating point unit (FPU) and SysAD bus interface, and are useful in a wide range of application areas including LBP, networks and set-top boxes. A debug support unit (DSU) is also built in, and this enables real-time PC tracing and various types of execution control.
