Product details
Overview
AT24C08N-10SC-2.7 from Microchip Technology (formerly Atmel) is an 8K-bit (1024 × 8) two-wire serial EEPROM optimized for low-voltage embedded systems. It operates from 2.7V to 5.5V, supports 100 kHz I²C bus timing, features hardware write protection via the WP pin, and delivers 1 million write cycles with 100-year data retention - deployed in industrial sensor nodes, power meter firmware storage, and automotive body control modules.
For engineers reviewing the AT24C08N-10SC-2.7 datasheet, AT24C08N-10SC-2.7 pinout, AT24C08N-10SC-2.7 application, or AT24C08N-10SC-2.7 equivalent, key selection criteria include its 2.7V–5.5V supply range, 16-byte page write capability, SOIC-8 JEDEC package, and compatibility with standard I²C controllers requiring Schmitt-trigger noise immunity and ACK polling support.
Technical Context
The AT24C08N-10SC-2.7 implements a fixed 8K-bit memory array organized as 64 pages of 16 bytes each, requiring a 10-bit data word address for random access. Its I²C interface uses open-drain SDA with internal pull-up compatibility and supports START/STOP/ACK protocols per NXP UM10204 specification.
Device addressing uses only the A2 pin (A0 and A1 are NC), enabling up to two AT24C08 devices on a single bus. Write protection is controlled solely by the WP pin: tied to VCC for full-array lock, GND for read/write enable - no software lock required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 8 Kbit (1024 × 8 bits), organized in 64 pages of 16 bytes - enables efficient firmware parameter storage with page-aligned updates. |
| Supply Voltage Range | 2.7 V to 5.5 V - supports direct interfacing with 3.3 V microcontrollers and legacy 5 V systems without level shifting. |
| I²C Clock Frequency | 100 kHz max (at 2.7 V) - ensures reliable operation under noisy industrial conditions with sufficient timing margin. |
| Write Cycle Time | 10 ms maximum - defines minimum interval between write commands; requires ACK polling or timeout handling in host firmware. |
| Endurance & Retention | 1,000,000 write cycles / 100 years data retention - validated for long-life applications like utility meter calibration storage. |
| Operating Temperature | -40°C to +85°C - qualified for industrial and automotive under-hood environments per AEC-Q100 stress test alignment. |
| Package | 8-lead JEDEC SOIC (8S1), 3.9 mm × 4.9 mm footprint - compatible with standard reflow profiles and automated PCB assembly. |
Pinout & Package
AT24C08N-10SC-2.7 is housed in an 8-lead JEDEC-standard SOIC package (8S1), 0.150" wide, with gull-wing leads and 1.27 mm pitch. Pin 1 is marked by a beveled corner or dot; device orientation follows JEDEC MS-001BA.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0 | No Connect | Not bonded internally; must be left floating or tied to GND/VCC - no effect on device addressing. |
| A1 | No Connect | Not bonded internally; no electrical function - unused in AT24C08 family addressing scheme. |
| A2 | Device Address Input | Hardwired address bit: determines one of two possible I²C slave addresses (0x50 or 0x51) on shared bus. |
| GND | Ground Reference | Return path for all internal circuitry and I²C bus; must connect to system ground plane with low impedance. |
| VCC | Power Supply | Primary supply input (2.7–5.5 V); requires local 100 nF ceramic decoupling capacitor placed within 5 mm. |
| WP | Write Protect Control | Active-high hardware lock: logic high (VCC) disables all write operations to entire memory array. |
| SCL | Serial Clock Input | Positive-edge clock for data transfer; requires external pull-up resistor (typically 2.2–10 kΩ) to VCC. |
| SDA | Serial Data I/O | Open-drain bidirectional bus line; shares pull-up with SCL; supports multi-master arbitration and ACK signaling. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Enables robust I²C communication in electrically noisy environments (e.g., motor drives, power supplies) without external filtering. |
| 16-byte page write mode | Reduces firmware overhead by allowing burst writes across one memory page - cuts write transaction count by up to 16× vs. byte-write. |
| Partial page write support | Permits writing fewer than 16 bytes into a page without corrupting existing data - simplifies non-aligned configuration updates. |
| Self-timed write cycle | Eliminates need for host-controlled timing delays; internal state machine manages erase/write/verify - improves system predictability. |
| Hardware write protection | Prevents accidental overwrites during power brownouts or firmware glitches - critical for calibration and security-critical data. |

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, 2.7–5.5 V, SOIC-8; differs in marking (D suffix), tape-and-reel packaging, and RoHS-compliant finish. | No functional difference; identical timing, pinout, and AC/DC specs - drop-in replacement for volume production. | Select when sourcing from Microchip's current standard production line with full traceability and extended lifecycle support. |
| BR24G08NUX-10 | 8K-bit I²C EEPROM from ROHM; supports 1.7–5.5 V, 400 kHz @ 5 V, but only 100 kHz @ 1.7–1.95 V - narrower low-Vcc timing margin. | Lacks dedicated WP pin; write protection implemented via software lock bits - less robust against power failure corruption. | Choose for cost-sensitive designs where 1.7 V operation is mandatory and hardware WP is not required. |
Compared with AT24C08N-10SC-2.7, AT24C08D-SSHM-T offers identical functionality with updated packaging and compliance, while BR24G08NUX-10 trades hardware write protection and guaranteed 100 kHz operation down to 2.7 V for broader ultra-low-voltage support - making AT24C08N-10SC-2.7 optimal for industrial reliability-critical use cases.

FAQ
What is the memory organization of the AT24C08N-10SC-2.7?
The AT24C08N-10SC-2.7 contains 8,192 bits of EEPROM memory organized as 1,024 words of 8 bits each (1024 × 8). Internally, it is structured into 64 pages of 16 bytes each, requiring a 10-bit data word address for random access. This layout supports both byte-write and 16-byte page-write operations, with automatic address incrementing within each page.
Does the AT24C08N-10SC-2.7 support I²C standard-mode or fast-mode timing?
The AT24C08N-10SC-2.7 supports I²C standard-mode operation at up to 100 kHz when powered from 2.7 V to 5.5 V. It does not support fast-mode (400 kHz) at 2.7 V - that speed is only guaranteed for 5.0 V operation (4.5–5.5 V) per the AT24C08 datasheet AC characteristics table. For 2.7 V systems, 100 kHz is the validated maximum clock frequency.
How is device addressing configured on the AT24C08N-10SC-2.7?
The AT24C08N-10SC-2.7 uses only the A2 pin for hardware device addressing; A0 and A1 are no-connect pins. With A2 tied to GND or VCC, the device responds to I²C slave addresses 0x50 or 0x51 respectively. This allows up to two AT24C08 devices on the same I²C bus - a key constraint distinguishing it from the 1K/2K variants that use all three address pins.
What is the function of the WP pin on the AT24C08N-10SC-2.7?
The WP (Write Protect) pin on the AT24C08N-10SC-2.7 provides hardware-level write inhibition. When WP is driven high (to VCC), all write operations - including byte, page, and sequential writes - are blocked across the entire 8K-bit memory array. When WP is low (GND), normal read and write functions operate. This feature prevents accidental or malicious overwrites during power transitions or firmware faults.
Is the AT24C08N-10SC-2.7 compatible with 1.8 V I²C buses?
No, the AT24C08N-10SC-2.7 is not rated for 1.8 V operation. Its "-2.7" suffix specifies a minimum operating voltage of 2.7 V (range: 2.7 V to 5.5 V). For 1.8 V systems, Microchip offers the AT24C08-10SC-1.8 variant - which has different DC and AC specifications, including reduced maximum clock frequency (100 kHz) and adjusted input thresholds. Using AT24C08N-10SC-2.7 below 2.7 V risks functional failure or data corruption.
