The µPD23C128040BL and µPD23C128080BL are a 134,217,728 bits mask-programmable ROM. The word organization is selectable (BYTE mode : 16,777,216 words by 8 bits, WORD mode : 8,388,608 words by 16 bits). With 44-pin PLASTIC SOP package products, only WORD mode can be used; it is not possible to switch to BYTE mode. The active levels of OE (Output Enable Input).
