Key Features
- 128Kbit (32K x 8) SPI EEPROM with 10MHz high-speed clock interface enables fast non-volatile data access in embedded systems
- 1,000,000 write/erase cycle endurance with 200-year minimum data retention ensures long service life in write-intensive applications
- 2.5V low-voltage operation in an 8-pin SOIC-8 package with standard SPI interface for simple microcontroller integration
Applications
The 25LC128-I/SN is well-suited for embedded systems requiring fast, reliable SPI-connected non-volatile memory, such as automotive ECUs, industrial controllers, and IoT devices storing configuration data, calibration parameters, and event logs. Its 10MHz SPI clock enables significantly faster data access than I2C-based EEPROMs, reducing latency in applications with frequent non-volatile read operations. The 8-pin SOIC package and standard SPI interface make it a drop-in replacement in designs already using SPI peripherals.

Frequently Asked Questions
What interface does the 25LC128-I/SN use and how fast is it?
The 25LC128-I/SN uses a 4-wire SPI (Serial Peripheral Interface) with a maximum clock frequency of 10MHz. SPI is significantly faster than I2C EEPROMs (typically 400kHz or 1MHz), enabling rapid data access in applications that require frequent reads of large data blocks, such as firmware parameter tables or lookup tables.
What is the storage capacity of the 25LC128-I/SN?
The 25LC128-I/SN provides 128Kbit (131,072 bits) of non-volatile EEPROM storage, organized as 32,768 x 8-bit (32K bytes). This capacity is suitable for storing configuration data, calibration coefficients, serial numbers, event logs, and small data tables in microcontroller-based embedded systems.
How long does the 25LC128-I/SN retain data and how many write cycles does it support?
The 25LC128-I/SN guarantees a minimum data retention time of 200 years and supports 1,000,000 write/erase cycles per memory location. This combination of high endurance and long retention makes it suitable for applications with frequent updates, including runtime counters, odometer storage, and real-time configuration updates.
What package does the 25LC128-I/SN come in?
The 25LC128-I/SN comes in an 8-pin SOIC (Small Outline Integrated Circuit) package with manufacturer code SOIC-8 and JESD-30 code R-PDSO-G8. This widely available surface-mount package is compatible with standard PCB assembly processes and is easy to hand-solder for prototyping.
