µPD23C32040AL, 23C32080AL are 33,554,432 bits mask-programmable ROM. The word organization is selectable (BYTE mode: 4,194,304 words by 8 bits, WORD mode: 2,097,152 words by 16 bits). The active levels of OE (Output Enable Input) can be selected with mask-option. The µPD23C32040AL and µPD23C32080AL are packed in 48-pin PLASTIC TSOP(I) and 44-pin PLASTIC SOP.
The NEC uPD23C32040AL and uPD23C32080AL are 32‑Mbit mask‑programmable ROM devices with selectable word organization (4,194,304 × 8 bits in BYTE mode or 2,097,152 × 16 bits in WORD mode). Active levels of the output‑enable pin are mask‑programmable, and the devices operate from 2.7 V to 3.6 V.
The data sheet provides detailed ordering information, pin configurations for 48‑pin TSOP and 44‑pin SOP packages, input/output functions, block diagram, and CMOS handling notes. It also includes specifications such as page access modes, supply current, and timing parameters.
