It operates from a single 4.5 V to 5.5 V supply. ## Commercial temperature grade — indoor use only Rated for 0°C to 70°C ambient operating temperature, this part is intended for commercial equipment in climate-controlled environments: office peripherals, telecom line cards in conditioned racks, test equipment, and similar indoor PCBs. It is not specified for automotive under-hood, outdoor base stations, or unheated industrial enclosures where the ambient may drop below freezing or exceed 70°C. ## 150 ns access time — what it means for bus timing The 150 ns access time is the maximum delay from address valid to data valid on the output pins. Write cycles also complete in 150 ns per word or page.","metaTitle":"Intel N28F256A150 256Kbit Parallel Flash, 150 ns, 32-PLCC","metaDescription":"Intel N28F256A150 256Kbit (32K x 8) parallel Flash memory, 150 ns access time, 4.5-5.5V supply, 0-70°C, 32-PLCC.
