Two-wire serial interface
512k EEPROM (64-kword × 8-bit)
ADE-203-1239 (Z)
Preliminary
Rev. 0.0
Jan. 10, 2001
Description
HN58X24512I is the two-wire serial interface EEPROM (Electrically Erasable and Programmable ROM).
It realizes 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. It also has a 128-
byte page programming function to make it’s 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.
Features
• Single supply: 1.8 V to 5.5 V
• Two-wire serial interface (I2CTM serial bus*1)
• Clock frequency: 1 MHz (2.5 V to 5.5 V)/400 kHz (1.8 V to 2.5 V)
• Power dissipation:
Standby: 3 µA (max)
Active (Read): 2 mA (max)
Active (Write): 5 mA (max)
• Automatic page write: 128-byte/page
• Write cycle time: 10 ms (2.5 V to 5.5 V)/15 ms (1.8 V to 2.5 V)
• Endurance: 105 Cycles (Page write mode)
• Data retention: 10 Years
Preliminary: The specification of this device are subject to change without notice. Please contact your
nearest Hitachi’s Sales Dept. regarding specification.

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 1
MHz.
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.

High-to-low and low-to-high change of SDA should be done during SCL low periods.
