Description
The R1WV3216R Series is a family of low voltage 32-Mbit static RAMs organized as 2097152-words by 16-bit,
fabricated by Renesas's high-performance 0.15um CMOS and TFT technologies.
The R1WV3216R Series is suitable for memory applications where a simple interfacing , battery operating and
battery backup are the important design objectives.
The R1WV3216R Series is made by stacked-micro-package technology and two chips of 16Mbit superSRAMs
are assembled in one package.
The R1WV3216R Series is packaged in a 52pin micro thin small outline mount device[
碌
TSOP / 10.79mm x
10.49mm with the pin-pitch of 0.4mm] or a 48balls fine pitch ball grid array [f-BGA / 7.5mmx8.5mm with the ball-pitch
of 0.75mm and 6x8 array] . It gives the best solution for a compaction of mounting area as well as flexibility of wiring
pattern of printed circuit boards.
