R1LV3216R Series
32Mb Advanced LPSRAM (2M word x 16bit / 4M word x 8bit)
REJ03C0367-0100
Rev.1.00
2009.05.07
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.
Features
Single 2.7~3.6V power supply
Small stand-by current: 4 µA (3.0V, typical)
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
Ordering Information
Type No.
