Key Features
- 1 kbit (128 bytes) SPI EEPROM operating at 1.8 V to 5.5 V, compatible with 3.3 V and 5 V microcontroller systems without level shifters
- 10 MHz maximum SPI clock enabling fast page writes and reads in time-sensitive embedded logging and configuration applications
- 1,000,000 write/erase cycle endurance with 200-year data retention in an 8-pin PDIP-8 package for through-hole prototyping and repair-friendly designs
Applications
The 25AA010A-I/P stores calibration constants, device configuration bytes, and serial number data in microcontroller-based systems that require non-volatile memory on a 3-wire SPI bus. Its 1.8 V minimum supply makes it directly compatible with low-power IoT nodes and battery-backed RTC modules operating from a single lithium cell. The 8-pin DIP package suits prototyping boards, field-replaceable modules, and legacy industrial equipment where through-hole components simplify manual rework.

Frequently Asked Questions
What supply voltage range and SPI clock speed does the 25AA010A-I/P support?
The 25AA010A-I/P operates from 1.8 V to 5.5 V and supports SPI clock frequencies up to 10 MHz at 2.5 V to 5.5 V, or up to 3 MHz at 1.8 V to 2.5 V as noted in the additional feature specification. This dual-speed behavior lets the device integrate directly with 3.3 V ARM Cortex-M microcontrollers at 10 MHz without external level translators, or with ultra-low-power MSP430 systems operating at 1.8 V core voltage.
How many write cycles can the 25AA010A-I/P endure, and what does this mean for a product with daily configuration saves?
The 25AA010A-I/P is rated for 1,000,000 write/erase cycles per byte location. A product that saves configuration data once per day would exhaust the write endurance after approximately 2,739 years, making wear leveling unnecessary for configuration and calibration storage use cases. For high-frequency logging at 100 writes per hour, endurance would last approximately 11.4 years, still sufficient for most embedded product lifetimes.
How does the 25AA010A-I/P 1 kbit capacity compare to a 25AA040A for a microcontroller with 64 bytes of calibration data?
The 25AA010A-I/P provides 128 bytes of storage, double the 64-byte calibration requirement and leaving 64 bytes free for future firmware expansion or additional trim values. The 25AA040A provides 512 bytes (4 kbit), which is 8× more storage than needed, increasing per-unit cost without functional benefit for a fixed 64-byte calibration block. The 25AA010A-I/P is therefore the more cost-effective choice for this specific 64-byte use case.
Can the 25AA010A-I/P replace an I2C EEPROM in a board redesign, and what interface changes are required?
No, the 25AA010A-I/P uses a 4-wire SPI interface (CS, SCK, SI, SO) rather than the 2-wire I2C protocol, so replacing an I2C EEPROM requires firmware changes to switch from I2C read/write transactions to SPI byte-transfer commands. The 8-pin PDIP footprint matches many 8-pin I2C EEPROM packages, but the CS pin replaces the SCL line and SO replaces SDA, meaning at least 3 PCB traces must be rerouted and the address pin configuration differs between the two protocols.
