- Internally self-timed write cycle, allowing the external clock to be stopped or left running after the start of a write cycle.
- Write protection mechanism with a Protection Register and a One Time Programming (OTP) bit to lock the Protection Register content.
- Supports Read, Write, Page Write, Write All, and other instructions for memory management.
- Low power Standby Power mode to reduce power consumption when not in use.
- Automatically increments the internal address counter for sequential data read.
Applications
- Industrial control systems requiring non-volatile memory.
- Automotive systems where data needs to be retained even after power loss.
- Consumer electronics such as set-top boxes, gaming consoles, and other devices needing serial memory access.
- Medical devices that require reliable and secure data storage.
- IoT devices and smart home appliances that need to store configuration data or user settings.
