Frequently Asked Questions
What interface does the 11AA020-I/SN use?
The 11AA020-I/SN uses Microchip's UNI/O single-wire serial interface operating at up to 1MHz maximum clock frequency. This proprietary protocol requires only a single I/O pin for both data and clock, significantly reducing pin count requirements compared to traditional SPI or I2C memory interfaces.
What is the memory density of the 11AA020-I/SN?
The 11AA020-I/SN has a total memory density of 2048 bits (2Kbit), providing sufficient storage for configuration parameters, device identification numbers, and calibration data in embedded system designs where a small non-volatile memory footprint is needed.
How durable is the 11AA020-I/SN in terms of write cycles?
The 11AA020-I/SN is rated for 1,000,000 write/erase cycles minimum, offering outstanding endurance for applications requiring frequent data updates. It also provides a minimum data retention time of 200 years, ensuring long-term reliability of stored data throughout the product lifetime.
What package does the 11AA020-I/SN come in?
The 11AA020-I/SN is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package, a widely-used surface-mount format that offers a good balance between compact size and ease of PCB assembly. The package is Pb-free (RoHS compliant) with JESD-609 e3 moisture sensitivity rating.
