Product details
Overview
AT24C01-10SC-1.8 from Microchip Technology (formerly Atmel) is a 1K-bit (128 × 8) I²C-compatible serial EEPROM optimized for ultra-low-voltage embedded systems. It operates from 1.8V to 5.5V, supports 100 kHz I²C communication at 1.8V, features 4-byte page write mode, and delivers 1 million write cycles with 100-year data retention - used in battery-powered sensors, smart meters, and firmware configuration storage.
For engineers reviewing the AT24C01-10SC-1.8 datasheet, AT24C01-10SC-1.8 pinout, AT24C01-10SC-1.8 application, or AT24C01-10SC-1.8 equivalent, key selection considerations include its 1.8V minimum supply, JEDEC SOIC-8 package, 10 ms max write cycle time, and compatibility with microcontroller I²C peripherals requiring low-power nonvolatile memory with guaranteed endurance.
Technical Context
The AT24C01-10SC-1.8 implements a standard two-wire I²C interface with open-drain SDA and Schmitt-triggered SCL inputs, supporting standard-mode (100 kHz) timing at 1.8V. Its internal architecture uses a 7-bit word address space mapped across 128 bytes of nonvolatile storage, with automatic address incrementing during page writes.
It employs self-timed internal write cycles with no external polling required beyond ACK polling, and includes hardware-level ESD protection (>3000V HBM). The device enters standby mode after STOP condition receipt, drawing only 3 µA typical at 1.8V - critical for always-on edge nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 1024 bits (128 × 8), sufficient for calibration data, device IDs, or small configuration tables |
| Supply Voltage Range | 1.8V to 5.5V - enables direct interfacing with 1.8V logic families without level shifters |
| I²C Clock Frequency | 100 kHz max at 1.8V - matches standard-mode I²C timing budgets for low-power MCU peripherals |
| Write Cycle Time | 10 ms maximum - defines minimum interval between successive write operations |
| Endurance | 1 million write cycles - supports frequent recalibration or logging in industrial monitoring |
| Data Retention | 100 years at +25°C - ensures long-term validity of stored firmware parameters or security keys |
| Standby Current | 3 µA typical at 1.8V - minimizes quiescent power in battery-backed real-time clock modules |
Pinout & Package
AT24C01-10SC-1.8 is supplied in an 8-pin JEDEC SOIC package (package code 8S1), 3.90 mm × 4.90 mm body, 1.27 mm lead pitch, gull-wing leads. Pin 1 marked by notch or bevel; pin 1 corner located at top-left when notch faces up.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0, A1, A2 | Device Address Inputs | Hardwired logic levels set 3-bit I²C slave address (0x50–0x57); unused pins must be tied to VCC or GND |
| SDA | Serial Data I/O | Open-drain bidirectional bus line - requires external pull-up resistor (typically 2.2–10 kΩ) |
| SCL | Serial Clock Input | Input-only clock line with Schmitt trigger - tolerant of slow rise/fall times on noisy boards |
| VCC | Power Supply | 1.8V–5.5V input; decoupling capacitor (0.1 µF) required within 10 mm of pin |
| GND | Ground Reference | Return path for all internal circuitry and I/O; must connect to system ground plane |
| TEST | Factory Test Input | Internally connected to GND or VCC during production test; must be externally tied to GND or VCC in application |
| NC | No Connect | Three pins (1, 2, 3 in SOIC) are unconnected - no routing or soldering required |
Key Features
| Feature | Design Value |
|---|---|
| 1.8V Operation | Enables direct integration into 1.8V FPGA I/O banks or ultra-low-power microcontrollers without voltage translation |
| 4-Byte Page Write | Reduces I²C transaction overhead by up to 75% vs. byte writes when storing consecutive configuration registers |
| ACK Polling Support | Allows host MCU to detect write completion without fixed delays - improves system responsiveness and power efficiency |
| Industrial Temp Range | -40°C to +85°C operation (per ordering code suffix 'I'; this part is commercial grade 0°C to +70°C) |
| ESD Protection >3000V | Meets IEC 61000-4-2 Level 3 for contact discharge - reduces need for external TVS on I²C lines |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| M24C01-RMN6TP | STMicroelectronics 1K I²C EEPROM; 1.7V–5.5V range; 400 kHz @ 5V only; 5 ms write cycle | Higher speed at 5V but no 100 kHz guarantee below 2.5V; different pinout (no TEST/NC pins) | Select if system operates ≥2.5V and requires faster writes; verify I²C timing margins at target VCC |
| BR24G01FJ-3GE2 | Rohm 1K I²C EEPROM; 1.6V–5.5V; 1 MHz max @ 5V; 5 ms write cycle; built-in write protect | Includes software write protection register; smaller 2.9 mm × 2.8 mm TSSOP8 package | Choose for enhanced data security in firmware update paths or space-constrained layouts |
Compared with AT24C01-10SC-1.8, M24C01-RMN6TP offers faster write timing but lacks guaranteed 100 kHz operation at 1.8V, while BR24G01FJ-3GE2 adds write protection and smaller footprint at the cost of different address mapping and control register implementation.

FAQ
What is the minimum operating voltage for AT24C01-10SC-1.8?
The AT24C01-10SC-1.8 is rated for operation down to 1.8V, with full functionality including 100 kHz I²C communication, 4-byte page writes, and guaranteed 1 million write cycles. Below 1.8V, timing parameters and reliability are not specified - design margin should maintain VCC ≥1.8V across temperature and load conditions. The AT24C01-10SC-1.8 datasheet explicitly defines 1.8V as the lower limit of its operational range.
Does AT24C01-10SC-1.8 support standard-mode or fast-mode I²C?
The AT24C01-10SC-1.8 supports standard-mode I²C (100 kHz) across its entire 1.8V–5.5V supply range. At 5.0V, it also supports fast-mode (400 kHz), but that speed is not guaranteed below 2.5V. For designs using 1.8V logic, only 100 kHz operation is assured - confirmed by AC Characteristics table in the AT24C01-10SC-1.8 datasheet with tLOW/tHIGH min/max values specified for "1.8-volt" column.
How many write cycles can AT24C01-10SC-1.8 endure?
The AT24C01-10SC-1.8 guarantees 1 million write cycles per memory location, validated per JEDEC JESD22-A117 standard. This endurance applies to both byte and page writes, and is specified at 25°C with VCC = 1.8V–5.5V. Endurance remains valid across the commercial temperature range (0°C to +70°C), making AT24C01-10SC-1.8 suitable for applications requiring daily updates over 10+ years.
What package type does AT24C01-10SC-1.8 use?
AT24C01-10SC-1.8 uses an 8-pin JEDEC-standard SOIC package (package code 8S1), measuring 3.90 mm × 4.90 mm with 1.27 mm lead pitch. The 'SC' in the part number explicitly denotes SOIC; pin 1 is located at the top-left corner adjacent to the package notch. This package is compatible with standard reflow profiles and automated optical inspection (AOI) systems.
Is AT24C01-10SC-1.8 qualified for automotive applications?
No - AT24C01-10SC-1.8 is rated for commercial temperature range (0°C to +70°C) and is not AEC-Q200 qualified. For automotive use, Microchip offers the AT24C01-10SI-1.8 variant ('I' suffix), which is tested and qualified for -40°C to +85°C operation. The AT24C01-10SC-1.8 datasheet specifies only commercial-grade reliability testing and thermal limits.
