The RMLV1616A-U Series is a family of 16Mbit asynchronous SRAMs organized 1,048,576-word × 16-bit. The RMLV1616A-U Series realizes higher soft error immunity compared to typical SRAMs with on-chip ECC, achieved by Renesas’ unique Advanced LPSRAM technologies. Therefore, it is suitable for battery backup systems. It is offered in a 48-pin TSOP (I) or 48-ball fine pitch ball grid array.
