AT28HC64B-12JU-T

As a premier 64Kbit Parallel EEPROM, the AT28HC64B-12JU-T is engineered to deliver exceptional performance and efficiency in high-speed applications. With access times as rapid as 55ns and a power dissipation rate of only 220mW, this EEPROM sets a new standard for reliability. Its CMOS standby current, measuring below 100μA when deselected, showcases its impressive energy efficiency. Offering the convenience of operation akin to static RAM for read or write cycles without external components, this device simplifies integration into existing systems. The presence of a 64-byte page register feature enables the simultaneous writing of up to 64 bytes, enhancing productivity. Additionally, the optional Software Data Protection mechanism ensures data integrity by preventing unintended writes, enhancing data security. The inclusion of an extra 64 bytes of EEPROM space opens up possibilities for device identification or tracking, making this product a versatile solution for diverse applications
