1 Mbit asynchronous SRAM in 32-SOJ — board-fit and speed grade
The Renesas 71V124SA10TYG8 is a 1 Mbit asynchronous SRAM organized as 128K x 8 bits, with a 10 ns access time that places it in the fast-page category for cache tag RAM, FIFO buffers, or microcontroller data memory where deterministic read/write latency matters. Housed in a 32-pin SOJ (Small Outline J-Lead) package (32-BSOJ, 0.300" body width, 7.62 mm), the part mounts on the board surface with a J-bend footprint — the same pad layout used by many 32-pin SOJ SRAMs, which simplifies PCB reuse across density upgrades.
Supply and temperature — 3.3 V logic, commercial range
The 10 ns write cycle time (word, page mode) matches the read access speed, keeping read-modify-write operations symmetric.
