Description

Renesas Technology’s HN58V65A series and HN58V66A series are electrically erasable and programmable EEPROM’s organized as 8192-word × 8-bit. They have realized high speed, low power consumption and high reliability by employing advanced MNOS memory technology and CMOS process and circuitry technology. They also have a 64-byte page programming function to make their write operations faster.
