25LC256T-I/SN serial EEPROM
The 25LC256T-I/SN from Microchip Technology is a 256-Kbit (32K x 8) serial EEPROM that utilizes the industry-standard SPI (Serial Peripheral Interface) bus for communication . Housed in a compact 8-pin SOIC package, this non-volatile memory device operates over a wide voltage range of 2.5V to 5.5V and an industrial temperature range of -40°C to +85°C . It features a maximum clock frequency of 10 MHz, enabling fast data transfer, and is organized as 32,768 bytes, making it suitable for storing configuration data, calibration constants, and event logs in various embedded systems .
The 25LC256T-I/SN is engineered for applications requiring reliable, non-volatile data storage with a simple serial interface. Its primary uses include industrial automation systems (PLCs, motor controllers) for storing parameters and operational data, and automotive electronics (infotainment, ECUs) for calibration data and event logging . It is also widely adopted in consumer electronics (smart home devices, wearables) for user settings, in medical devices for patient data and configuration, and in IoT sensor nodes for data logging and firmware updates .
Alternative SPI EEPROMs
● AT25256 (Microchip/Atmel): A directly compatible 256Kb SPI EEPROM from the same manufacturer, often considered a functional equivalent with similar specifications and pinout .
● M95M02 (STMicroelectronics): A 2-Mbit SPI EEPROM offering four times the density of the 25LC256, suitable for applications requiring larger non-volatile storage within the same SPI interface framework .
● IS25LQ256 (ISSI): A 256Kb SPI Flash memory with similar density and interface, but based on NOR Flash technology which may offer faster read speeds and different write/erase characteristics .
● W25X256 (Winbond): A 256M-bit Serial Flash memory (note: much larger capacity) with a standard SPI interface, targeting applications requiring significantly more storage, such as code execution or large data sets .
● BR25S256FJ-WE2 (ROHM): A 256Kbit SPI Bus EEPROM from ROHM, featuring a wide voltage range (1.7V to 5.5V) and automotive-grade qualifications, making it a robust alternative for automotive and industrial uses .
