Description

HN58X24xxI 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.

Note: Hitachi’s serial EEPROM are authorized for using consumer applications such as cellular phone,

camcorders, audio equipment. Therefore, please contact Hitachi’s sales office before using
industrial applications such as automotive systems, embedded controllers, and meters.

Pin Function

Serial Clock (SCL)

The SCL pin is used to control serial input/output data timing. The SCL input is used to positive edge
clock data into EEPROM device and negative edge clock data out of each device. Maximum clock rate is
400 kHz.

Serial Input/Output Data (SDA)

The SDA pin is bidirectional for serial data transfer. The SDA pin needs to be pulled up by resistor as that
pin is open-drain driven structure. Use proper resistor value for your system by considering VOL, IOL and
the SDA pin capacitance. Except for a start condition and a stop condition which will be discussed later,
the SDA transition needs to be completed during SCL low period.

Note: High-to-low and low-to-high chang of SDA should be done during SCL low periods.
