1. DIFFERENCES BETWEEN
μ
PD784908 SUBSERIES PRODUCTS
The only difference between the
μ
PD784907 and
μ
PD784908 is their internal memory capacities.
The
μ
PD78P4908 is produced by replacing the mask ROM in the
μ
PD784907 or
μ
PD784908 with 128-Kbyte one-
time PROM. Table 1-1 shows the differences between these products.
