Surface-mount assembly with the 10 ns access time means the part keeps up with a 100 MHz bus without wait states, provided the PCB trace length from the memory controller to the TSOP is kept under 150 mm to hold the signal-integrity budget. ## 512K x 8 organization — the byte-wide bus decision Organised as 512K words of 8 bits each, this SRAM presents a byte-wide parallel interface. For an 8-bit microcontroller or a 32-bit processor that can byte-lane address individual memory banks, the 512K x 8 map simplifies the address decoding — the upper address lines select the chip, and the lower 19 lines (A0–A18) cycle through the 512K locations. The 10 ns write cycle time (word, page) matches the read access, so the bus turnaround is symmetric — no extra idle cycles needed between read and write bursts when the controller's memory timing is set for 10 ns.","metaTitle":"Renesas 71V424S10PHG SRAM, 4Mbit, 10ns, 44-TSOP II","metaDescription":"Renesas 71V424S10PHG 4Mbit asynchronous SRAM, 512K x 8, 10ns access, 3V-3.6V, 44-TSOP II.

The 71V416L10BEG comes in a tray package and uses a 3.0 V supply. The pinout differs — the 71V416L10BEG is a 44-pin TSOP but the data bus width is 16 bits, so a board designed for the 71V424S10PHG's byte-wide bus would need a layout change to accommodate the wider data path."},{"question":"What compliance documentation does Renesas provide for 71V424S10PHG?","answer":"The part is RoHS3 compliant.
