The 55 ns write cycle time (word, page) matches the read access, so the bus timing budget is symmetric — no need to stretch the write pulse beyond the read window. This matters when the memory controller runs at a fixed cycle time and the SRAM sits on a shared address/data bus with other peripherals. ## Industrial temp range and 32-sTSOP footprint The 32-sTSOP package (11.80 mm width, 0.465\" body) is a fine-pitch surface-mount footprint — the 0.50 mm lead pitch demands a controlled solder profile and a stencil aperture sized for the lead width, not the pad. Bulk packaging means the parts ship loose in tubes or trays, not on tape-and-reel. For a kitting line feeding a pick-and-place, this adds a manual tube-handling step — plan for a tube feeder or a tray shaker, not a reel pocket.","metaTitle":"Renesas R1LP0108ESA-5SI#B0 1Mbit Parallel SRAM, 55 ns","metaDescription":"R1LP0108ESA-5SI#B0 from Renesas Electronics — 1Mbit parallel SRAM, 55 ns access time, 4.5V-5.5V supply, -40°C to 85°C.
