MEMORY IC

Serial EEPROM

HT93LCxx 

The HT93LCxx family is a serial EEPROM with 3-wire interface.^. Advance CMOS floating gate non-volatile memory process is used to design the reliable device. The memory capacity range from 1K to 4K^. and the memory organization can be configured in 8 bits or 16 bits^. data word selected by the ORG pin. These devices offer the best^. features including low power consumption, over 1M rewrite cycles per^. word, 10-year data retention,  0^oC ~ +70^oC wide range operating temperature. Available in 8-pin DIP and SOP package types ...^. Memory programmer information
