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.
