DATA SHEET MOS INTEGRATED CIRCUIT µ PD23C128000BL 128M-BIT MASK-PROGRAMMABLE ROM 16M-WORD BY 8-BIT (BYTE MODE) / 8M-WORD BY 16-BIT (WORD MODE) Description The µPD23C128000BL is 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 µPD23C128000BL is packed in 48-pin PLASTIC TSOP (I) and 44-pin PLASTIC SOP.
