Visão Geral
Description
The M95020-WMN6TP offers 2 Kbits of memory organized as 256 x 8 bits. It uses an SPI (Serial Peripheral Interface) for communication, which supports high-speed data transfers and allows for easy interfacing with microcontrollers and other digital devices. Key features include byte and page write capabilities, along with hardware write protection via a write-protect pin, which enhances data security.
This EEPROM is commonly used in applications requiring non-volatile storage for system configuration, calibration data, or other critical information that must be retained without power. It comes in multiple package options, including SO-8 and TSSOP-8, providing flexibility for various design requirements.
