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.
