To all our customers
Regarding the change of names mentioned in the document, such as Hitachi
Electric and Hitachi XX, to Renesas Technology Corp.
The semiconductor operations of Mitsubishi Electric and Hitachi were transferred to Renesas
Technology Corporation on April 1st 2003. These operations include microcomputer, logic, analog
and discrete devices, and memory chips other than DRAMs (flash memory, SRAMs etc.)
Accordingly, although Hitachi, Hitachi, Ltd., Hitachi Semiconductors, and other Hitachi brand
names are mentioned in the document, these names have in fact all been changed to Renesas
Technology Corp. Thank you for your understanding. Except for our corporate trademark, logo and
corporate statement, no changes whatsoever have been made to the contents of the document, and
these changes do not constitute any alteration to the contents of the document itself.

Cautions
Keep safety first in your circuit designs!
1. Renesas Technology Corporation puts the maximum effort into making semiconductor products better
and more reliable, but there is always the possibility that trouble may occur with them. Trouble with
semiconductors may lead to personal injury, fire or property damage.
Remember to give due consideration to safety when making your circuit designs, with appropriate
measures such as (i) placement of substitutive, auxiliary circuits, (ii) use of nonflammable material or
(iii) prevention against any malfunction or mishap.

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.
