Application Examples
APPLICATION EXAMPLES
The lowest cost DSP56001A-based system is shown in Figure 4-1. It uses no run time external
memory and requires only two chips, the DSP56001A and a low cost EPROM. The EPROM read
access time should be less than 780 nanoseconds when the DSP56001A is operating at a clock rate
of 20.5 MHz.
