Applications
The 25AA160B-I/P is well-suited for storing calibration coefficients, configuration parameters, and event logs in microcontroller-based systems such as industrial sensors, medical monitors, and consumer appliances. Its 4-wire SPI interface requires minimal MCU pins, making it easy to add non-volatile memory to pin-constrained designs. The through-hole PDIP package makes it a popular choice for prototyping and educational projects before transitioning to SMT alternatives.

Frequently Asked Questions
What is the memory size and SPI clock speed of the 25AA160B-I/P?
The 25AA160B-I/P provides 16 Kbit (2 KB) of EEPROM storage accessible over a 4-wire SPI interface at up to 10 MHz clock frequency. This allows rapid sequential byte or page reads at speeds that are compatible with virtually all microcontroller SPI masters operating at 5 V or 3.3 V supply levels.
How many write cycles can the 25AA160B-I/P endure and how long does it retain data?
The 25AA160B-I/P is rated for a minimum of 1,000,000 write/erase cycles per byte, which is sufficient for frequent configuration updates in industrial and consumer devices. Data retention is guaranteed for a minimum of 200 years at room temperature, ensuring that stored calibration coefficients, product serial numbers, and event logs remain intact over the entire product lifecycle.
When is the through-hole PDIP package of the 25AA160B-I/P preferred over an SMT EEPROM variant?
The 8-pin PDIP package on a 2.54 mm through-hole pitch is preferred during hardware prototyping, in educational lab boards, and in low-volume hand-assembled products where SMT soldering equipment is unavailable. It also fits directly into standard DIP-8 IC sockets, allowing the 25AA160B-I/P to be swapped without soldering during development and testing, which speeds up firmware iteration.
Is the 25AA160B-I/P compatible with 3.3 V and 5 V microcontroller systems?
Yes, the 25AA160B-I/P operates over a supply voltage range compatible with both 3.3 V and 5 V systems (check the datasheet for the exact VCC range, typically 1.8 V to 5.5 V for the 25AA series). At 10 MHz SPI clock, it interfaces directly with PIC, AVR, and ARM MCUs without level-shifting in 3.3 V designs, reducing BOM cost and design complexity for dual-voltage embedded boards.
