AT24C01A-10SC-2.5

Memory IC Overview

The AT24C01A-10SC-2.5 is a 1K-bit (128 x 8) serial electrically erasable and programmable read-only memory (EEPROM) manufactured by Microchip Technology. It operates within a supply voltage range of 2.5V to 5.5V and supports I²C bus frequencies up to 100 kHz at this voltage level. The device is housed in an 8-lead JEDEC SOIC package and is rated for commercial operation temperatures from 0°C to +70°C.

Memory IC Feature Summary

• Features a hardware write protect pin that enables full array protection when connected to VCC, preventing unintended data modification.
• Supports bidirectional data transfer via a two-wire serial interface with Schmitt trigger filtered inputs for noise suppression.
• Includes self-timed write cycles with automatic erase capabilities and allows partial page writes for flexible data management.

Memory IC Applications

• Industrial control systems requiring low-power non-volatile storage
• Commercial embedded applications needing configuration parameter retention
• Systems utilizing I²C buses for sensor data logging

Memory IC Procurement Notes

Verify the specific ordering suffix matches the required voltage and temperature grade. Confirm the package type corresponds to the design footprint. Ensure the component meets RoHS compliance requirements for the target assembly process. Cross-reference the manufacturer date code with project specifications.

Memory IC Selection Notes

Select this variant for designs requiring 2.5V minimum operation with standard voltage tolerance. The 10 ns access time designation indicates performance suitable for general-purpose microcontroller interfacing. Consider the 8-lead SOIC form factor for space-constrained PCB layouts compared to larger packages.
