1. DIFFERENCES BETWEEN

µPD784038 SUB-SERIES SPECIAL PRODUCTS

The only difference between the

µPD784031(A), µPD784035(A), and µPD784036(A) is their capacity of internal

memory.

The

µPD78P4038(A) is produced by replacing the masked ROM in the µPD784031(A), µPD784035(A), or

µPD784036(A) with 128K-byte one-time PROM or EPROM. Table 1-1 shows the differences between these products.

µPD784038 Sub-Series Special Products

2. DIFFERENCES BETWEEN STANDARD AND SPECIAL PRODUCTS

Table 2-1 shows the differences between standard and special products.
