EXTENDED TEMPERATURE OPERATION  
Description  
The µPD43256B-X is a high speed, low power, and 262,144 bits (32,768 words by 8 bits) CMOS static RAM.  
The µPD43256B-X is an extended-operating-temperature version of the µPD43256B (X version : TA = –25 to +85  
°C). And A and B versions are low voltage operations. Battery backup is available.  
The µPD43256B-X is packed in 28-pin plastic TSOP (I) (8 x 13.4 mm).
