Asynchronous SRAM, 1 Mbit, 10 ns access
The Renesas 71V124SA10YGI is a 1 Mbit asynchronous SRAM organized as 128K x 8 bits, with a 10 ns access time that sets the read-cycle floor for the bus. The 10 ns figure is the address-to-data valid delay — a 100 MHz bus master sees one wait state at most before the data is stable on the I/O pins. The 10 ns write cycle time matches the read access, so the memory can sustain back-to-back read-write transitions at the same bus rate.
32-SOJ package and temperature grade
Housed in a 32-SOJ (Small Outline J-lead) package, the 71V124SA10YGI is a surface-mount device with a 0.400-inch body width and 10.16 mm body width. The J-lead footprint is common for mid-density SRAMs of this era and reflows with standard lead-free profiles. The supplier device package is designated 32-SOJ. ROHS3 compliant.
