Balancing cybersecurity and functional safety! The memory itself protects the data within it.
The "W77Q Series" is a secure flash memory that can add security features to existing models without security functions by replacing the standard flash memory currently in use. It enables application features such as secure boot, secure OTA, and secure storage. The tamper detection feature of SPI communication improves signal quality and contributes to functional safety. Additionally, since security features can be added without changing the PCB, it helps reduce development costs and makes use of existing assets. 【Features】 ■ 100% inherits the pin configuration and instruction set of conventional SPI flash memory ■ Operates like standard memory when security features are turned off ■ Detects and protects against unauthorized access through SPI command authentication ■ Hides addresses and data flowing on the SPI bus during read/write operations using stream encryption ■ Offers products ranging from 16Mb to 128Mb with a Vcc voltage of 1.8V *For more details, please download the PDF or feel free to contact us.
