The 70 ns access time sets the read-cycle ceiling for the bus it connects to — a microcontroller or ASIC with a 70 ns or slower memory interface can use it without wait states. ## Supply and temperature constraints for the BOM The commercial temperature range (0°C to 70°C) limits deployment to indoor, climate-controlled equipment; no industrial or automotive ambient rating. The parallel memory interface requires a full 8-bit data bus and up to 16 address lines. Board layout must match the 32-TSOP I footprint (0.724\" body width, 18.40 mm) — a fine-pitch TSOP land pattern with via fan-out under the body. ## Lifecycle and compliance reality The part is RoHS non-compliant (lead-bearing solder finish), which may exempt it under certain legacy equipment directives but blocks use in new RoHS-mandated builds without a waiver.","metaTitle":"CY27C512-70ZC 512Kbit EPROM, 70 ns, 32-TSOP I","metaDescription":"CY27C512-70ZC 512Kbit parallel EPROM, 70 ns access, 4.5-5.5V, 32-TSOP I.
