µPD784031

1. DIFFERENCES BETWEEN µPD784038 SUB-SERIES

The only difference between the µPD784031, µPD784035, µPD784036, µPD784037, and µPD784038 is their

capacity of internal memory.

The µPD78P4038 is produced by replacing the masked ROM in the µPD784035, µPD784036, µPD784037, or

µPD784038 with 128K-byte one-time PROM or EPROM. Table 1-1 shows the differences between these products.
