Frequently Asked Questions
What interface and maximum clock frequency does the 25AA080B-I/ST use?
The 25AA080B-I/ST uses a 4-wire SPI (Serial Peripheral Interface) with a maximum clock frequency of 10 MHz. This high-speed SPI interface allows fast sequential reads and efficient page writes from low-voltage microcontrollers in embedded systems.
What is the memory organization and page write buffer size of the 25AA080B-I/ST?
The 25AA080B-I/ST is organized as 1K x 8 bits (8Kb total) with a 32-byte page write buffer. Page writes allow up to 32 bytes to be written in a single write cycle, improving throughput when updating large blocks of configuration or calibration data.
What are the endurance and data retention characteristics of the 25AA080B-I/ST?
The 25AA080B-I/ST supports a minimum of 1,000,000 write/erase cycles per byte and guarantees data retention for at least 200 years, providing long-term reliability for applications with frequent configuration updates or data logging.
What package does the 25AA080B-I/ST use and what is its operating voltage?
The 25AA080B-I/ST is packaged in an 8-pin TSSOP (Thin Shrink Small Outline Package, JESD-30 Code R-PDSO-G8). It operates from a 1.8V supply voltage, making it directly compatible with modern low-voltage microcontrollers and SoCs without level shifting.
