Microchip Technology's 28C64A-25-VS is a 64-kbit CMOS Electrically Erasable Programmable Read-Only Memory (EEPROM) organized as 8K words by 8 bits. This parallel interface device features a maximum access time of 250 nanoseconds, enabling efficient data retrieval. The 28C64 series supports automatic write operations and includes data polling functionality for status monitoring. Designed for surface mounting, it utilizes a 28-lead Thin Small Outline Package (TSOP1) with a 0.55mm terminal pitch. Operating from a 4.5V to 5.5V supply voltage range, it is suitable for applications requiring reliable non-volatile data storage. Industries such as industrial automation, automotive systems, and consumer electronics commonly employ this component for configuration data, parameter storage, and firmware. The standby current is rated at 100 microamperes maximum, with a maximum active supply current of 30 milliamperes.
