The 0.465-inch (11.80 mm) width is the standard thin small-outline footprint for 28-pin SRAMs; it shares a common pad layout with other 28-TSOP parallel memory devices. Mounting is surface-mount only — no through-hole option.","metaTitle":"R1LP5256ESA-7SI#B0 256Kbit SRAM, 70 ns, 28-TSOP","metaDescription":"R1LP5256ESA-7SI#B0 is a 256Kbit parallel SRAM with 70 ns access time, 4.5V-5.5V supply, -40°C to 85°C range.
