What are the key features of 25AA160B-I/MS?
- 16 Kbit (2K x 8) SPI EEPROM with 32-byte page write buffer, minimizing host write transactions
- Low 1.8 V minimum operating voltage supporting battery-powered and low-voltage embedded systems
- 1,000,000 write/erase cycle endurance with 200-year minimum data retention for high-reliability storage
What is 25AA160B-I/MS used for?
The 25AA160B-I/MS is ideal for storing non-volatile configuration data, calibration parameters, and event logs in space-constrained embedded systems. Its 1.8 V operation and 8-pin MSOP package make it a popular choice for wearable devices, IoT sensor nodes, and portable medical equipment where board area and power budget are tightly managed. The 10 MHz SPI interface allows fast sequential reads, well suited to boot-parameter loading or firmware version storage in microcontroller-based designs.

Frequently Asked Questions
What is the maximum SPI clock frequency supported by the 25AA160B-I/MS, and how does it affect throughput?
The 25AA160B-I/MS supports a maximum SPI clock frequency of 10 MHz, allowing a peak sequential read throughput of approximately 10 Mbit/s when using Mode 0,0 or Mode 1,1 SPI. For a 16 Kbit (2,048-byte) array, a full sequential read completes in about 1.6 ms at 10 MHz, making it practical for firmware parameter loading during system startup.
How does the 25AA160B-I/MS perform in high-write-cycle applications such as data logging?
The 25AA160B-I/MS is rated for 1,000,000 write/erase cycles per address location, providing excellent endurance for frequent-write data logging applications. Its 32-byte page write capability reduces the number of write operations needed, further extending effective memory life. Data retention is guaranteed for a minimum of 200 years at room temperature, ensuring long-term data integrity even after the maximum write cycle count is reached.
When should a designer choose the 25AA160B-I/MS over a larger-density SPI EEPROM?
The 25AA160B-I/MS is the preferred choice when the non-volatile storage requirement fits within 16 Kbit (2,048 bytes), such as storing MAC addresses, device serial numbers, factory calibration coefficients, or boot configuration tables. Its 8-pin MSOP package occupies minimal PCB area, and its 1.8 V minimum supply voltage avoids the need for level translation when interfaced directly to modern low-voltage microcontrollers operating at 1.8 V to 3.3 V.
