Product details
Overview
AT24C01-10SC-2.7 from Microchip Technology (formerly Atmel) is a 1K-bit (128 × 8) serial EEPROM with 2-wire I²C-compatible interface, optimized for low-voltage embedded systems operating from 2.7V to 5.5V. It supports 100 kHz clock frequency, 4-byte page write mode, and delivers 1 million write cycles with 100-year data retention - used in industrial sensor calibration storage, printer consumable identification, and power meter firmware parameter backup.
For engineers reviewing the AT24C01-10SC-2.7 datasheet, AT24C01-10SC-2.7 pinout, AT24C01-10SC-2.7 application, or AT24C01-10SC-2.7 equivalent, key selection factors include its 2.7V–5.5V supply range, JEDEC SOIC-8 package, 10 ms max write cycle time, and compatibility with standard I²C bus timing at 100 kHz under low-voltage conditions.
Technical Context
The AT24C01-10SC-2.7 implements a fixed 7-bit slave address with three hardware address inputs (A0–A2), enabling up to eight devices on a single I²C bus. Its memory is organized as 128 individually addressable 8-bit words, accessed via byte or 4-byte page write operations.
It uses open-drain SDA/SCL signaling with internal pull-up requirements, supports START/STOP condition generation, ACK polling for write completion detection, and features automatic address rollover during sequential reads - all compliant with standard I²C protocol semantics at VCC = 2.7V–5.5V.

FAQ
What is the operating voltage range for AT24C01-10SC-2.7?
The AT24C01-10SC-2.7 operates from 2.7V to 5.5V DC. This "-2.7" suffix explicitly denotes the 2.7V minimum supply rating, distinguishing it from 5.0V-only (e.g., AT24C01-10SC) or 1.8V variants. Operation below 2.7V is not guaranteed and may result in data corruption or communication failure.
Does AT24C01-10SC-2.7 support 400 kHz I²C communication?
No, AT24C01-10SC-2.7 supports up to 100 kHz I²C clock frequency when operating at 2.7V–5.5V. The 400 kHz rating applies only to the 5.0V-specific variants (e.g., AT24C01-10SC). Attempting 400 kHz operation with AT24C01-10SC-2.7 will violate AC timing specifications and likely cause communication errors.
How many devices can share the same I²C bus with AT24C01-10SC-2.7?
Up to eight AT24C01-10SC-2.7 devices can coexist on a single I²C bus. This is enabled by the three hardware address pins (A0, A1, A2), each configurable as HIGH or LOW to generate unique 3-bit address codes - forming part of the 7-bit I²C slave address.
What is the function of the TEST pin on AT24C01-10SC-2.7?
The TEST pin on AT24C01-10SC-2.7 is reserved for factory testing and must be externally tied to either GND or VCC during normal operation. Leaving it floating violates the absolute maximum ratings and may cause unpredictable behavior. It has no user-accessible function in application circuits.
Is AT24C01-10SC-2.7 suitable for automotive applications?
AT24C01-10SC-2.7 is rated for commercial temperature range (0°C to +70°C) and is not qualified for automotive use. Automotive-grade equivalents (e.g., AT24C01C-SSHM-T) undergo AEC-Q100 stress testing and operate from -40°C to +125°C - these are distinct part numbers with different qualification status and packaging.
