AT28HC64B-70SU Allgemeine Beschreibung

The AT28HC64B-70SU, manufactured by Microchip, is a cutting-edge 64Kbit Parallel EEPROM designed for high-performance applications. With access times as fast as 55ns and a power dissipation of only 220mW, this EEPROM sets a new standard in efficiency. Additionally, its CMOS standby current is impressively low, at less than 100μA when deselected. This EEPROM can be accessed like static RAM for both read and write cycles, eliminating the need for external components. Furthermore, it boasts a 64-byte page register, allowing for the simultaneous writing of up to 64 bytes, enhancing efficiency even further. The optional Software Data Protection mechanism adds an extra layer of security, preventing unintended writes. Moreover, the device includes an additional 64 bytes of EEPROM memory, perfect for device identification or tracking purposes
