Micron Technology, Inc. Memory MT25QL256BBB1EW7-CSIT

The MT25QL256BBB1EW7-CSIT is a 256Mbit (32MB) SPI NOR Flash memory device from Quarktwin Technology Ltd. It features a quad I/O interface that supports high-speed data transfer rates up to 90 MB/s. The device operates at a maximum clock frequency of 133 MHz at 3.0V and 166 MHz at 1.8V, making it suitable for applications requiring fast read and write operations. This memory device includes advanced security features such as a replay protected monotonic counter (RPMC) and an authenticated core root of trust for measurement (A-CRTM). It offers various erase capabilities, including bulk, sector (64KB), and subsector (4KB and 32KB) erases, along with a dedicated 64-byte OTP area that is user-lockable. The device is designed for high endurance, with a minimum of 100,000 erase cycles per sector and a typical data retention of 20 years. The MT25QL256BBB1EW7-CSIT is available in a RoHS-compliant package and is suitable for a wide range of applications, including those requiring robust security measures.
