The industrial grade means the timing parameters are guaranteed across the full temperature range, not just at 25°C — important when the access time budget tightens at temperature extremes. ## Package and footprint — 32-TSOP I Housed in a 32-TSOP I (0.724\" body width, 18.40 mm), this is a standard thin small-outline package with a JEDEC footprint that matches other 32-pin TSOP I SRAMs from the same era. The surface-mount package is reflow-compatible; MSL rating is typical for this class — verify the floor-life window before opening the moisture barrier bag. The base product number CY7C109 covers multiple speed and temperature variants; the -10ZXI suffix selects the 10 ns industrial-grade version in TSOP I.","metaTitle":"Infineon CY7C109D-10ZXI 1Mbit Async SRAM, 10 ns, 32-TSOP I","metaDescription":"Infineon CY7C109D-10ZXI asynchronous SRAM, 1Mbit (128K x 8), 10 ns access time, 4.5V-5.5V supply, -40°C to 85°C industrial temp.
