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.
