256K MPS µPort Saver EEPROM is a high-performance EEPROM launched by Xicor. It features 25ns read time, 10MHz data transfer rate, low power consumption and small package.
The Xicor X84256 is a 256K MPS EEPROM designed for direct interface with microprocessors and microcontrollers. It eliminates the need for I/O ports, interface glue logic, or parallel-to-serial converters, thereby saving board space and power. The device supports data transfer rates up to 10MHz with a read access time of 25ns, enabling no-wait-state operation for most host systems.
