4 Mbit async SRAM with 12 ns access — what that means for the bus
The Renesas 71V416L12YG8 is a 4 Mbit asynchronous SRAM organized as 256K x 16, with a 12 ns access time and a parallel interface. It runs on a 3 V to 3.6 V supply.
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
The 71V416L12YG8 is listed as Active on the manufacturer's lifecycle status. For a BOM line that needs a stable SRAM supply, this part doesn't carry obsolescence risk right now.
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. The supply range is narrow (3 V to 3.6 V).
