1. DIFFERENCES BETWEEN
μ
PD78P4038 AND MASKED ROM PRODUCTS
The
μ
PD78P4038 is produced by replacing the masked ROM in the
μ
PD784035,
μ
PD784036,
μ
PD784037, or
μ
PD784038 with PROM to which data can be written. The functions of the
μ
PD78P4038 are the same as those of
the
μ
PD784035,
μ
PD784036,
μ
PD784037, or
μ
PD784038 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.
