Product details
Overview
AT24C08AN-10SC-2.7 from Microchip Technology (formerly Atmel) is an 8K-bit (1024 × 8) I²C-compatible serial EEPROM with hardware write protection, low-voltage operation (2.7V–5.5V), and 100 kHz maximum clock frequency at 2.7V. It features 16-byte page write capability, 1 million write cycles endurance, and 100-year data retention-used for configuration storage in embedded controllers, power management units, and sensor calibration modules.
For engineers reviewing the AT24C08AN-10SC-2.7 datasheet, AT24C08AN-10SC-2.7 pinout, AT24C08AN-10SC-2.7 application, or AT24C08AN-10SC-2.7 equivalent, key selection criteria include VCC operating range (2.7V–5.5V), WP pin functionality for hardware-level memory protection, 16-byte page write mode, Schmitt-triggered SDA/SCL inputs for noise immunity, and JEDEC SOIC-8 package compatibility with industrial temperature support.
Technical Context
The AT24C08AN-10SC-2.7 implements a 2-wire I²C interface with bidirectional open-drain SDA and edge-triggered SCL, supporting standard-mode (100 kHz) timing at 2.7V. Its internal address space is organized into four 256-page blocks, requiring a 10-bit word address for random access.
Write protection is enforced via the WP pin: when tied to VCC, the full 8K array is locked against writes; when grounded, full read/write access is enabled. Addressing uses only the A2 pin (A0/A1 are NC), allowing up to two AT24C08A devices on a single bus.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 8192 bits (1024 × 8), enabling storage of firmware flags, calibration coefficients, or device ID strings |
| Supply Voltage Range | 2.7V to 5.5V - supports direct interfacing with 3.3V microcontrollers without level shifters |
| Max Clock Frequency | 100 kHz at 2.7V - ensures reliable I²C communication under low-power brownout conditions |
| Page Write Size | 16 bytes - reduces write transaction overhead vs. byte-write-only EEPROMs |
| Endurance | 1 million write cycles - suitable for systems requiring frequent parameter updates (e.g., energy meter logs) |
| Data Retention | 100 years at +25°C - guarantees long-term validity of stored calibration or security keys |
| Write Cycle Time | 10 ms max - defines minimum interval between successive write commands |
Pinout & Package
AT24C08AN-10SC-2.7 is housed in an 8-pin JEDEC SOIC package (8S1), 0.150" wide, with gull-wing leads and RoHS-compliant finish. Pin 1 is marked by a beveled corner or dot; the package supports reflow soldering per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0 | Device Address Input | No-connect (NC) for AT24C08A - unused in address decoding |
| A1 | Device Address Input | No-connect (NC) for AT24C08A - unused in address decoding |
| A2 | Device Address Input | Hardwired address bit - selects one of two possible I²C addresses (0x50 or 0x51) |
| GND | Ground Reference | Return path for VCC and signal currents; must be low-impedance for noise immunity |
| VCC | Power Supply | Primary supply input (2.7V–5.5V); decoupling capacitor required within 10 mm |
| WP | Write Protect Control | Hardware lock: high = full-array write disable; low = normal read/write operation |
| SCL | Serial Clock Input | Positive-edge sampled clock - synchronizes all I²C data transfers |
| SDA | Serial Data I/O | Bidirectional open-drain line - requires external pull-up resistor (typically 2.2–10 kΩ) |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Enables robust I²C operation in electrically noisy environments (e.g., motor drives, power supplies) |
| Partial page writes | Allows writing fewer than 16 bytes per transaction without corrupting adjacent data in the same page |
| Self-timed write cycle | Eliminates need for external write-complete polling delay - host can proceed after STOP condition |
| ESD protection >3000V | Meets HBM Class 2 requirements - reduces risk of field failure during handling or system integration |
| Industrial temperature range | -40°C to +85°C operation - validated for use in automotive body control modules and industrial PLCs |
Applications
| Smart Energy Meter | Industrial PLC I/O Module |
|---|---|
Use Scenario: Storing tariff schedules, pulse-count history, and tamper-event timestamps across power outages. IC Role / Device Role / Timing Role: Nonvolatile configuration and event-log storage with guaranteed 100-year data retention.

IC Role / Device Role / Timing Role: Secure, traceable configuration storage with write-protection enforced at hardware level. Use Value: Meets FDA design controls for permanent record retention - 1M endurance supports >10 years of daily usage at 300 cycles/year. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| M95M01-RDW6TP | 1 Mbit SPI interface (vs. I²C), 5V-only supply (4.5–5.5V), no WP pin - requires software-controlled write enable | Requires SPI-capable MCU; unsuitable for I²C-bus-constrained designs or low-voltage systems | Select only if existing design uses SPI and operates strictly at 5V with no need for hardware write lock. |
| BR24G08NUX-10 | 8K-bit I²C EEPROM, 1.7–5.5V range, 400 kHz max at 2.7V+, built-in write protect register (not pin-based) | Higher speed at same voltage; software-configurable protection replaces WP pin logic | Prefer when dynamic protection control is needed - but verify MCU firmware supports register-based lock/unlock sequence. |
Compared with M95M01-RDW6TP and BR24G08NUX-10, AT24C08AN-10SC-2.7 offers deterministic hardware write protection via WP pin, guaranteed 100 kHz operation at 2.7V, and JEDEC SOIC-8 footprint compatibility - making it optimal for cost-sensitive, low-voltage I²C systems requiring fail-safe memory locking.

FAQ
What is the maximum I²C clock frequency supported by AT24C08AN-10SC-2.7?
The AT24C08AN-10SC-2.7 supports up to 100 kHz I²C clock frequency when operated at 2.7V–5.5V. This is specified in the AC Characteristics table under fSCL for 2.7V/2.5V/1.8V versions. It does not support 400 kHz - that rating applies only to the 5.0V version (e.g., AT24C08A-10SC).
How does the WP pin function on AT24C08AN-10SC-2.7?
On AT24C08AN-10SC-2.7, the WP pin provides hardware-level write protection: when pulled high to VCC, the entire 8K memory array is write-protected; when grounded, full read/write access is enabled. This behavior is confirmed in the Pin Description and WP Pin Status table in the datasheet.
Which pins are unused (NC) on AT24C08AN-10SC-2.7?
A0 and A1 are no-connect (NC) pins on AT24C08AN-10SC-2.7. As stated in the Pin Description section, only A2 is used for device addressing - enabling two possible I²C addresses (0x50 or 0x51) - while A0 and A1 are internally disconnected and must be left unconnected.
What package type is used for AT24C08AN-10SC-2.7?
AT24C08AN-10SC-2.7 uses an 8-pin JEDEC SOIC package (designated 8S1), 0.150" wide, with gull-wing leads. This is explicitly listed in the AT24C08A Ordering Information table and Packaging Information section, confirming compatibility with standard SOIC-8 footprints and reflow profiles.
Does AT24C08AN-10SC-2.7 support partial page writes?
Yes, AT24C08AN-10SC-2.7 supports partial page writes: up to 16 bytes may be written in a single transaction, and fewer than 16 bytes may be sent without affecting data outside the addressed page boundaries. This is documented in the "Page Write" subsection under Device Operation.
