Description

The R1LV3216R Series is a family of low voltage 32-Mbit static RAMs organized as 2,097,152-word by 16-bit, fabricated by Renesas’s high-performance 0.15um CMOS and TFT technologies.
The R1LV3216R Series is suitable for memory applications where a simple interfacing, battery operating and battery backup are the important design objectives.
The R1LV3216R Series is provided in 48-pin thin small outline package [TSOP (I): 12mm x 20mm with pin pitch of 0.5mm] and 52-pin micro thin small outline package [μTSOP (II): 10.79mm x 10.49mm with pin pitch of 0.4mm]. It gives the best solution for compaction of mounting area as well as flexibility of wiring pattern of printed circuit boards.
