Frequently Asked Questions
What is the storage capacity and interface of the 25AA020A-I/MS?
The 25AA020A-I/MS provides 2K bits (2048 bits) of EEPROM storage organized as 256 bytes (256 x 8). It uses a 4-wire SPI interface with a maximum clock frequency of 10MHz at 2.5V to 5.5V, enabling fast read and write access with minimal host processor overhead.
What voltage range does the 25AA020A-I/MS support?
The 25AA020A-I/MS operates from 1.8V to 5.5V supply voltage, making it compatible with 1.8V, 2.5V, 3.3V, and 5V microcontroller platforms. This wide voltage range is particularly valuable for ultra-low-power designs using 1.8V core voltage processors common in IoT and wearable applications.
What are the write endurance and data retention ratings of the 25AA020A-I/MS?
The 25AA020A-I/MS is rated for a minimum of 1,000,000 erase/write cycles per byte, ensuring reliable operation even in applications with frequent memory updates such as data logging or parameter adjustment. Data retention is guaranteed for a minimum of 200 years after the last write operation.
What package is the 25AA020A-I/MS available in?
The 25AA020A-I/MS is available in an MSOP-8 package (JESD-30 code S-PDSO-G8), which is significantly smaller than a standard SOIC-8. This makes it one of the most compact surface-mount EEPROM options available, suitable for miniaturized PCBs in wearables, hearing aids, and tiny sensor modules.
How does the 25AA020A-I/MS compare to the 25AA010A for application selection?
The 25AA020A-I/MS offers twice the storage capacity (2K bits, 256 bytes) compared to the 25AA010A (1K bits, 128 bytes), in the same MSOP-8 package with identical voltage and speed specifications. It is the preferred choice when more than 128 bytes of non-volatile storage are needed without changing the board footprint or interface design.
