Key Features
- 16 Kbit (2 KB) SPI EEPROM with 10 MHz clock support enables fast non-volatile data storage in microcontroller-based designs
- 1 million write/erase cycle endurance with 200-year data retention ensures reliable long-term parameter and calibration storage
- Wide supply range of 2.5 V to 5.5 V in an 8-pin SOIC-8 package provides easy integration across 3.3 V and 5 V embedded systems
Applications
25LC160B-I/SN is used for storing non-volatile configuration data, calibration coefficients, and user settings in embedded systems such as industrial sensors, smart meters, and consumer electronics. Its SPI interface allows daisy-chaining multiple EEPROM devices on a single bus, useful in systems that need to expand storage without additional CS lines. The 1 million cycle endurance and 200-year data retention make it suitable for field-deployed equipment requiring infrequent but reliable parameter updates.

Frequently Asked Questions
How many bytes can 25LC160B-I/SN store and what page size does it use for write operations?
25LC160B-I/SN stores 2048 bytes (16 Kbit) of data, organized as 2048 × 8-bit addressable locations. Write operations use a 32-byte page buffer, meaning up to 32 bytes can be written in a single write cycle. Writing data that spans multiple 32-byte page boundaries requires separate write operations, each followed by a write cycle time of up to 5 ms.
How does 25LC160B-I/SN compare to 25LC080 for a design that stores 1 KB of calibration data?
25LC080 provides 8 Kbit (1 KB) of storage, just enough for 1 KB of calibration data with no spare capacity. 25LC160B-I/SN doubles the capacity to 16 Kbit (2 KB) in the same SOIC-8 footprint at a marginal cost increase, providing 50% headroom for firmware version updates or additional calibration tables without a PCB respin. Both share the 10 MHz SPI interface and 2.5 V to 5.5 V supply range.
What is the write endurance and data retention of 25LC160B-I/SN?
25LC160B-I/SN is rated for 1 million write/erase cycles per memory cell and a minimum data retention of 200 years at room temperature. This endurance is suitable for applications that update stored data infrequently, such as logging calibration constants once during manufacturing or updating a device configuration a few hundred times in the field over a 10-year product lifetime.
Can 25LC160B-I/SN be used in a 3.3 V microcontroller system without level shifting?
Yes, 25LC160B-I/SN operates from 2.5 V to 5.5 V, so a 3.3 V supply is within its specified range. The SPI clock frequency at 3.3 V is 10 MHz, and the input logic thresholds are 0.8× VCC (2.64 V) high and 0.2× VCC (0.66 V) low, fully compatible with 3.3 V CMOS logic outputs from common microcontrollers such as STM32, PIC, and AVR families without any level translation.
