Description

The RMLV1616A-U Series is a family of 16-Mbit asynchronous SRAMs organized 1,048,576-word × 16-bit.

The RMLV1616A-U Series has realized higher soft error immunity compared to typical SRAMs with on-chip ECC,

archived by Renesas’s unique Advanced LPSRAM technologies. Therefore, it is suitable for battery backup systems.

It is offered in 48pin TSOP (I) or 48-ball fine pitch ball grid array.

Features
