Description
The
PD23C128040BL and PD23C128080BL 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
PD23C128040BL and PD23C128080BL are packed in 48-pin PLASTIC TSOP(I) and 44-pin PLASTIC SOP.
