1. DIFFERENCES AMONG MODELS IN
µPD784038Y SUBSERIES
The only difference among the
µPD784031Y, 784035Y, 784036Y, 784037Y, and 784038Y lies in the internal memory
capacity.
The
µPD78P4038Y is provided with a 128-Kbyte one-time PROM or EPROM instead of the mask ROM of the
µPD784035Y, 784036Y, 784037Y, and 784038Y. These differences are summarized in Table 1-1.
