Microchip Technology's AT28C04F-20LMB is a 4-kilobit parallel CMOS EEPROM organized as 512 words by 8 bits. This component offers a maximum access time of 200 nanoseconds and a write cycle time of 200 microseconds. Designed for robust operation, it features a wide operating temperature range of -55°C to +125°C and meets MIL-STD-883 Class B (Modified) screening standards. The AT28C04 series employs a parallel interface for data access and supports data polling. With an endurance rating of 10,000 write cycles, this device is suitable for applications requiring reliable data retention in demanding environments, including aerospace, defense, and industrial control systems. It is packaged in a 32-lead ceramic chip carrier (CQCC32) with a terminal pitch of 1.270 mm.
