The Renesas 71V416L12YG8 is a 4 Mbit asynchronous SRAM organized as 256K x 16, with a 12 ns access time and a parallel interface.
Package and temperature — fits commercial indoor boards
Housed in a 44-SOJ package (10.16 mm width), this is a surface-mount part. The SOJ footprint is common on older telecom and networking boards; verify your board's pad layout matches before ordering.
Lifecycle and sourcing — still active, no LTB worry
Write cycle and supply — the fine print
The write cycle time matches the access time at 12 ns — so read and write cycles are symmetric.
