SRAM Chip Async Single 3V 32M-Bit 2M x 16 70ns 48-Pin FBGA

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 Advanced LPSRAMs are assembled in one package.The R1WV3216R Series is packaged in a 52pin micro thin small outline mount device[µTSOP / 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.
