The Microchip Technology 28C64A-25B-XA is a 64-kilobit 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 and operates with a nominal supply voltage of 5V. Built with advanced CMOS technology, it offers a wide operating temperature range from -55°C to +125°C, suitable for demanding environments. The component utilizes a 28-pin Ceramic Dual In-line Package (CDIP28) with through-hole mounting. Key features include data polling for status monitoring and a ready/busy signal. This non-volatile memory solution is commonly employed in industrial control, automotive applications, and military systems where robust data retention and reliable operation are critical. The write cycle time is a maximum of 1 microsecond.
