Product details
Overview
AT24C08N-10SC-2.5 from Microchip Technology (formerly Atmel) is an 8K-bit (1024 × 8) serial EEPROM IC optimized for low-voltage embedded systems. It operates from 2.5V to 5.5V, supports 100 kHz I²C bus speed, features hardware write protection via WP pin, and delivers 1 million write cycles with 100-year data retention. It serves as nonvolatile configuration storage in microcontroller-based industrial controllers.
For engineers reviewing the AT24C08N-10SC-2.5 datasheet, AT24C08N-10SC-2.5 pinout, AT24C08N-10SC-2.5 application, or AT24C08N-10SC-2.5 equivalent, key selection criteria include its 2.5V minimum supply, 8-lead SOIC package, 16-byte page write capability, and compatibility with standard 2-wire I²C protocol in space-constrained, power-sensitive designs.
Technical Context
The AT24C08N-10SC-2.5 implements a true 2-wire (I²C-compatible) serial interface with open-drain SDA and edge-triggered SCL, supporting standard-mode (100 kHz) timing at 2.5V–5.5V. Its internal memory is organized into 64 pages of 16 bytes each, requiring a 10-bit word address for random access.
Device addressing uses only the A2 pin (A0 and A1 are NC), enabling up to two AT24C08 devices on a single bus. The WP pin provides hardware-level write protection for the entire 8K array when pulled high, while Schmitt-trigger inputs and noise filtering ensure robust operation in electrically noisy environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 8 Kbit (1024 × 8 bits), sufficient for firmware calibration tables or device-specific configuration data |
| Supply Voltage Range | 2.5V to 5.5V - enables direct interfacing with 2.5V/3.3V logic without level shifters |
| I²C Clock Frequency | 100 kHz max at 2.5V - ensures timing compliance in low-power, battery-backed systems |
| Write Cycle Time | 10 ms max - defines minimum interval between successive byte/page writes |
| Endurance | 1 million write cycles - supports frequent parameter updates in field-deployed equipment |
| Data Retention | 100 years at +25°C - guarantees long-term storage integrity without refresh |

Pinout & Package
AT24C08N-10SC-2.5 is housed in an 8-lead JEDEC SOIC (8S1) package, 0.150" wide, with standard gull-wing leads and 1.27 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0 | No Connect | Not used for device addressing; must be left unconnected or tied to GND/VCC (no functional impact) |
| A1 | No Connect | Not used for device addressing; no electrical connection required |
| A2 | Device Address Input | Hard-wired address bit enabling up to two AT24C08 devices on one I²C bus |
| GND | Ground Reference | System return path for VCC and signal references; requires low-impedance PCB connection |
| VCC | Power Supply | 2.5V–5.5V main supply; bypass capacitor (0.1 µF) recommended near pin |
| WP | Write Protect Control | Active-high hardware lock: high = full-array write disable, low = normal read/write |
| SCL | Serial Clock Input | Positive-edge clock for I²C transactions; requires external pull-up resistor (typically 4.7 kΩ) |
| SDA | Serial Data I/O | Open-drain bidirectional bus line; shared across multiple I²C devices with single pull-up |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C08D-SSHM-T | Same 8K-bit capacity, 2.5V–5.5V range, but in 8-lead TSSOP (8T) package; identical pinout except physical footprint | TSSOP offers smaller board area and better thermal performance; not drop-in compatible due to different land pattern | Select for space-constrained designs where SOIC footprint is unavailable |
| M24C08-RMN6TP | STMicroelectronics 8K-bit EEPROM; supports 1 MHz I²C at 5V but only 400 kHz at 2.5V; same SOIC-8 package and pinout | Higher speed at 5V enables faster boot-time config loading; lower 2.5V speed may limit throughput in low-VCC systems | Select when 5V system speed is critical and ST's qualification pedigree is preferred |
Compared with AT24C08N-10SC-2.5, AT24C08D-SSHM-T offers identical functionality in a smaller TSSOP package, while M24C08-RMN6TP provides higher 5V I²C bandwidth but reduced 2.5V timing margin - both require layout review for mechanical fit or timing validation.

FAQ
What is the maximum I²C clock frequency supported by AT24C08N-10SC-2.5 at 2.5V?
The AT24C08N-10SC-2.5 supports a maximum I²C clock frequency of 100 kHz when operating at 2.5V. This is specified in the AC Characteristics table under "2.7-, 2.5-, 1.8-volt" conditions. At 5.0V, it supports up to 400 kHz, but the -2.5 suffix denotes optimization for the lower-voltage range where 100 kHz is the guaranteed timing limit for reliable communication. AT24C08N-10SC-2.5 must be configured accordingly in host firmware.
How many AT24C08N-10SC-2.5 devices can share the same I²C bus?
Up to two AT24C08N-10SC-2.5 devices can be addressed on a single I²C bus. This is because the AT24C08 uses only the A2 pin for hardware device addressing (A0 and A1 are no-connect), providing one binary address bit. The device address word includes three configurable bits (A2, A1, A0), but for AT24C08, only A2 is functional - yielding two possible addresses (0b1010000 and 0b1010001). AT24C08N-10SC-2.5 thus supports dual-device configurations without address conflict.
Does AT24C08N-10SC-2.5 support partial page writes?
Yes, AT24C08N-10SC-2.5 supports partial page writes: up to 16 bytes can be written in a single page-write transaction, and fewer than 16 bytes may be sent - the internal address counter increments automatically, wrapping within the current 16-byte page boundary. This allows efficient updates of non-aligned data blocks without requiring full-page erasure. AT24C08N-10SC-2.5 retains this behavior across all supported supply voltages and temperature ranges.
What is the function of the WP pin on AT24C08N-10SC-2.5?
The WP (Write Protect) pin on AT24C08N-10SC-2.5 is an active-high hardware control that disables all write operations to the entire 8K-bit memory array when driven to VCC. When WP is grounded, normal read and write functions operate. This feature prevents inadvertent writes during power transitions or firmware errors. AT24C08N-10SC-2.5 does not support selective sector protection - WP affects the full memory space.
Is AT24C08N-10SC-2.5 qualified for industrial temperature range?
Yes, AT24C08N-10SC-2.5 is rated for the industrial temperature range of –40°C to +85°C. The "-10" in the part number denotes 10 ms max write cycle time, "SC" specifies the 8-lead SOIC package, and "-2.5" indicates 2.5V–5.5V operation - all consistent with Microchip's industrial-grade AT24C08N variants. Absolute maximum ratings confirm operation up to +125°C, and DC/AC characteristics are fully specified across –40°C to +85°C. AT24C08N-10SC-2.5 is suitable for harsh-environment deployments.
