The Microchip Technology 28C64A-20I-P is a 64 Kbit (8K x 8) CMOS Electrically Erasable Programmable Read-Only Memory (EEPROM) featuring a parallel interface. This component offers a maximum access time of 200ns and operates asynchronously. Key features include Automatic Write, Bulk Erase functionality, and data retention exceeding 10 years. The device supports Data Polling for write operation monitoring and a Ready/Busy pin. Its 28-lead PDIP (Plastic Dual In-line Package) with through-hole mounting and 2.54mm terminal pitch makes it suitable for various industrial and commercial applications requiring non-volatile data storage. Operating temperature ranges from -40°C to +85°C, with supply voltages from 4.5V to 5.5V. The 28C64A-20I-P is widely utilized in embedded systems, industrial control, and data logging applications.
