UPD23C128080BL

DATA SHEET MOS INTEGRATED CIRCUIT µPD23C128040BL, 23C128080BL 128M-BIT MASK-PROGRAMMABLE ROM 16M-WORD BY 8-BIT (BYTE MODE) / 8M-WORD BY 16-BIT (WORD MODE) PAGE ACCESS MODE Description 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) can be selected with mask-option. The µPD23C128040BL and µPD23C128080BL are packed in 48-pin PLASTIC TSOP(I) and 44-pin PLASTIC SOP.
