25LC256T-E/SM

25LC256T-E/SM Description

The 25LC256T-E/SM is a high-performance 256Kbit (32K x 8) SPI serial EEPROM from Microchip Technology, designed for reliable non-volatile data storage in demanding applications. This surface-mount device operates over a wide voltage range (2.5V–5.5V), making it suitable for both low-power and standard-voltage systems. With a 10 MHz clock frequency and SPI interface, it ensures fast data transfer and seamless integration with microcontrollers and embedded systems. The 5ms write cycle time (word/page) and unlimited write endurance (typical for EEPROMs) make it ideal for frequent data updates. Packaged in an 8-SOIJ tape & reel (TR), it is RoHS3 compliant and REACH unaffected, meeting stringent environmental standards.
