Microchip Technology's 28C64F-20I-K is a 64-kilobit (65,536 bits) CMOS Electrically Erasable Programmable Read-Only Memory (EEPROM) with a parallel interface. This device features an 8K x 8 memory organization, providing efficient data storage for applications requiring non-volatile memory. The 28C64 series offers a fast access time of 200 nanoseconds, ensuring prompt data retrieval. Its robust CMOS technology contributes to low power consumption, with a standby current of 100 microamperes and a maximum supply current of 30 milliamperes at a nominal 5V supply. The 28C64F-20I-K supports data polling for efficient status monitoring and a ready/busy signal for write cycle management, with a maximum write cycle time of 200 microseconds. Encased in a 32-lead Ceramic Quad Flat Pack (CQFP), suitable for demanding operating environments with a temperature range of -40°C to +85°C, this component finds utility in industrial control systems, telecommunications equipment, and automotive electronics where reliable data retention is critical.
