Current dissipations and operating temperature ranges differ between
µ
PD75P308 and
µ
PD75308. For detail, refer to the specification documents of each mode.

Noise immunity and noise radiation differ because circuit scale and mask layout are
different.
2. DIFFERENCES BETWEEN
µ
PD75P308 AND
µ
PD75308
The
µ
PD75P308 is a model of the
µ
PD75308 and is equipped with a PROM instead of a mask ROM.
Programs can be rewritten to the PROM of the
µ
PD75P308. Table 2-1 shows the differences between the
µ
PD75P308 and
µ
PD75308. You should fully consider these differences when you debug or produce your
application system on an experimental basis by using the PROM model, and then proceed to mass-produce
the system by using the mask ROM model.
For the details of the CPU and the internal hardware, refer to
µ
PD75308 User's Manual (IEM-5016).

Note: The noise immunity and noise radiation differ between the PROM and mask ROM models. To replace
the PROM model with the mask ROM model in the course of experimental production to mass
production, evaluate your system by using the CS mode (not ES model) of the mask ROM model.
