23S08E-3DCGI

Overview

The Renesas 23S08E-3DCGI is an 8-bit serial EEPROM with a capacity of 1 kilobit (128 x 8 bits). It operates within a voltage range of 2.5V to 5.5V and supports standard I2C bus communication protocols. The device features a page write buffer of 8 bytes and includes hardware write protection capabilities. It offers high endurance with 1 million write cycles and data retention exceeding 40 years. The component is available in compact packages such as the 8-pin SOP, suitable for space-constrained embedded applications requiring non-volatile memory storage.

Feature Summary

• I2C compatible serial interface with support for multiple slave addresses
• Hardware write protect pin for enhanced data security
• Page write mode with 8-byte buffer for efficient data transfer
• Wide operating voltage range from 2.5V to 5.5V

Applications

• Consumer electronics configuration storage
• Industrial control system parameter logging
• Smart metering devices for usage data retention
• Embedded systems requiring small non-volatile memory

Procurement Notes

Verify the specific suffix '3DCGI' against official Renesas documentation to confirm package type, temperature grade, and tape/reel specifications. Ensure compatibility with existing PCB footprint and voltage levels before procurement. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when an 8-bit serial EEPROM with I2C interface is required. Consider the 1M cycle endurance and 40-year data retention for long-life applications. Verify that the operating voltage range matches the system power supply. Check package availability if space constraints are critical.

Part Context

This part belongs to the Renesas 23S series of serial EEPROMs. It shares architectural similarities with other members like the 23LCxxx or 24xxx series but uses I2C instead of SPI or parallel interfaces. The 23S08E variant specifically denotes the 1Kbit density within this family.

Replacement Considerations

Direct substitutes may include other 1Kbit I2C EEPROMs from vendors like Microchip or STMicroelectronics, provided pinouts and command sets are compatible. Verify electrical characteristics and timing parameters carefully. No officially confirmed substitute part numbers are listed in public documentation.
