The Microchip Technology 28C64AFT-20I-SO is a 64Kb CMOS EEPROM organized as 8K x 8 bits. This parallel interface device offers a maximum access time of 200ns and operates asynchronously. Key features include automatic write, bulk erase capability, and data retention exceeding 10 years. The Ready/Busy output simplifies write cycle management. Designed for robust operation, it supports a supply voltage range of 4.5V to 5.5V, with a nominal 5V requirement, and operates across industrial temperature ranges from -40°C to +85°C. The component is housed in a 28-lead PDSO (Small Outline) package with a 1.27mm terminal pitch, suitable for surface mounting. This EEPROM finds application in industrial control, automotive systems, and data logging applications requiring non-volatile memory.
