Description
The R1WV6416R Series is a family of low voltage 64-Mbit static RAMs organized as 4,194,304-word by
16-bit, fabricated by Renesas’s high-performance 0.15um CMOS and TFT technologies.
The R1WV6416R Series is suitable for memory applications where a simple interfacing, battery operating
and battery backup are the important design objectives.
The R1WV6416R Series is provided in 48-pin thin small outline package [TSOP (I): 12mm x 20mm with
pin pitch of 0.5mm], 52-pin micro thin small outline package [
µ
TSOP (II): 10.79mm x 10.49mm with pin pitch
of 0.4mm] and 48-ball fine pitch ball grid array [f-BGA] package. It gives the best solution for compaction of
mounting area as well as flexibility of wiring pattern of printed circuit boards.
