Microchip Technology's 28C64A-20B-XX is a 65,536-bit CMOS Electrically Erasable Programmable Read-Only Memory (EEPROM) organized as 8K words by 8 bits. This parallel access device offers a maximum access time of 200ns and operates over an extended temperature range of -55°C to +125°C. The 28C64A series supports data polling and features a ready/busy output for system status indication. Its robust CDIP28 package, with through-hole mounting and a 2.54mm terminal pitch, is suitable for demanding applications in industrial control, automotive systems, and telecommunications infrastructure. The component adheres to military screening standards, including 38535Q/M, 38534H, and 883B, ensuring high reliability. Its 5V nominal supply voltage and 1ms maximum write cycle time are key operational parameters.
