STMicroelectronics 256Kbit SPI EEPROM, SOIC-8, Surface Mount

The STMicroelectronics 256Kbit SPI EEPROM is a standard serial Electrically Erasable Programmable Memory designed for high-speed clock applications. As the most flexible type of non-volatile memory, this EEPROM is the ideal solution for parameter storage needs, particularly in environments with very heavy cycling requirements, numerous parameters, and high temperatures. It is organised as 32768 x 8 bits and is accessed through the SPI bus.

Key Features

• Compatible with the Serial Peripheral Interface (SPI) bus
• Additional write lockable page for identification purposes
• Write protect function for quarter, half, or the entire memory array
• Enhanced ESD protection for improved reliability
• Endurance of more than 4 million write cycles
• Data retention exceeding 200 years

This surface-mount memory IC operates with a supply voltage ranging from 2.5V to 5.5V and supports a maximum clock frequency of 10MHz. It is designed to function reliably across an operating temperature range of -40°C to 85°C.

Please note: This is an ESD sensitive device, and proper precautions must be taken while handling the component to prevent damage.
