Description

HN58X24xx series are two-wire serial interface EEPROM (Electrically Erasable and Programmable

ROM). They realize high speed, low power consumption and a high level of reliability by employing

advanced MNOS memory technology and CMOS process and low voltage circuitry technology. They also

have a 32-byte page programming function to make their write operation faster.

Features

• Single supply: 1.8 V to 5.5 V

• Clock frequency: 400 kHz

• Power dissipation:

 Standby: 3 µA(max)

 Active (Read): 1 mA(max)

 Active (Write): 3 mA(max)

• Automatic page write: 32-byte/page

• Write cycle time: 10 ms (2.7 V to 5.5 V )/15ms (1.8 V to 2.7 V )

• Data retention: 10 Years

• Small size packages: TSSOP-8pin and SOP-8pin
