Figure 5-2 Wait States Scheme — PZ, 120 MHz

As shown in Figure 5-1 and Figure 5-2, the TCM RAM can support program and data fetches at full CPU speed without any address or data wait states required.

The TCM flash can support zero address and data wait states up to a CPU speed of 50 MHz in nonpipelined mode. The flash supports a maximum CPU clock speed of 180 MHz in pipelined mode for the PGE Package, and 120 MHz for the PZ package.

The flash wrapper defaults to nonpipelined mode with zero address wait state and one random-read data wait state.
