Part identity and key features
The Renesas 71V416L15BEG is a 4 Mbit asynchronous SRAM organized as 256K x 16 bits, with a 15 ns access time and a parallel memory interface. It operates from a 3V to 3.6V supply. The part is housed in a 48-CABGA (9x9 mm) package and is rated for commercial temperature environments (0°C to 70°C).
Package and footprint considerations
The 48-CABGA (9x9 mm) package is a fine-pitch BGA — not hand-solderable without a rework station and stencil. The 0°C to 70°C rating means it's intended for indoor, climate-controlled equipment; not for automotive or outdoor telecom enclosures. Store the reels dry: BGA packages are moisture-sensitive, and the commercial temp grade doesn't change the MSL handling requirements.
