μPD43256B-X  
256K-BIT CMOS STATIC RAM  
32K-WORD BY 8-BIT  
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).
