R1W V3216R Series

32Mb superSRAM (2M wordx16bit)

Description

Features

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[

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.

• Single 2.7-3.6V power supply

• Small stand-by current:4

• Data retention supply voltage =2.0V

• No clocks, No refresh

• All inputs and outputs are TTL compatible.

• Easy memory expansion by CS1#, CS2, LB# and UB#

• Common Data I/O

• Three-state outputs: OR-tie capability

• OE# prevents data contention on the I/O bus

• Process technology: 0.15um CMOS
