1. DIFFERENCES BETWEEN µPD78P4038Y AND MASKED ROM PRODUCTS

The µPD78P4038Y is produced by replacing the masked ROM in the µPD784035Y, µPD784036Y, µPD784037Y,

or µPD784038Y with PROM to which data can be written. The functions of the µPD78P4038Y are the same as those

of the µPD784035Y, µPD784036Y, µPD784037Y, or µPD784038Y except for the PROM specification such as writing

and verification, except that the PROM size can be changed to 48 K, 64 K, or 96 Kbytes, and except that the internal

RAM size can be changed to 2,048 or 3,584 bytes.

Table 1-1 shows the differences between these products.
