Notes 1. The µPD78P054 is a PROM model of the µPD78052, 78053, and 78054.
2. The µPD78P058 is a PROM model of the µPD78055, 78056, and 78058.
3. The capacities of the internal PROM and internal high-speed RAM can be changed by using a memory
size select register (IMS).
4. The internal expansion RAM capacity can be changed by using an internal expansion RAM size select
register (IXS).
