Description
The R1LV1616R Series is a family of low voltage 16-Mbit static RAMs organized as 1048576-words by 16-bit,
fabricated by Renesas's high-performance 0.15um CMOS and TFT technologies.
The R1LV1616R Series is suitable for memory applications where a simple interfacing , battery operating and
battery backup are the important design objectives.
The R1LV1616RBA Series is packaged in a 48balls Wafer Level Chip Scale Package[WL-CSP / 5.62mm x 5.84mm
with the ball-pitch of 0.55mm and the height of 0.79mm]. It gives the best solution for a 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:2µA (3.0V, typ.)
• 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
