... Programing time is typically only 50 µs/byte. The Integrated Product Identification Code electronically identifies the device and manufacturer. This feature is used by industry-standard programming equipment to select the proper programming algorithms and voltages. The AT27LV520 programs exactly the same way as a standard 5V AT27C520 and uses the same programming equipment. 2. Pin Configurations ...
