In a 28-pin DIP (0.300\" body), this is the through-hole parallel memory for designs that need a drop-in replacement or a new build on a legacy board where the PLCC or SOJ footprint is not an option. ## Write cycle and bus timing The write cycle time equals the 25 ns access time — word or page mode — so the memory keeps up with a 40 MHz bus without wait states on back-to-back writes.","metaTitle":"Renesas 71256SA25TPG SRAM, 256Kbit, 25ns, 28-DIP","metaDescription":"Renesas 71256SA25TPG 256Kbit parallel SRAM, 25ns access, 4.5-5.5V, 0-70°C, 28-PDIP.
