Product details
Overview
AT24C08N-10SI-2.7 from Microchip Technology is an 8K-bit (1024 × 8) I²C-compatible serial EEPROM optimized for low-voltage industrial applications. It operates from 2.7V to 5.5V, supports 400 kHz I²C clock frequency at 2.7V+, features hardware write protection via WP pin, and delivers 1 million write cycles with 100-year data retention. It is used in embedded systems for parameter storage, calibration data logging, and configuration backup.
For engineers reviewing the AT24C08N-10SI-2.7 datasheet, AT24C08N-10SI-2.7 pinout, AT24C08N-10SI-2.7 application, or AT24C08N-10SI-2.7 equivalent, key selection criteria include I²C timing compliance at 2.7V, page-write capability (16-byte pages), WP pin behavior, SOIC-8 package compatibility, and extended temperature support (–40°C to +85°C).
Technical Context
The AT24C08N-10SI-2.7 implements a standard two-wire I²C interface with open-drain SDA and active-high SCL, supporting standard-mode (100 kHz) and fast-mode (400 kHz) operation under VCC ≥ 2.7V. Its internal address space is organized as 64 pages of 16 bytes each, requiring a 10-bit word address for random access.
It uses Schmitt-trigger inputs on SCL, SDA, and WP for noise immunity, includes built-in address decoding (A2 only active; A0/A1 are NC), and enters standby mode automatically after STOP condition or power-up. Write cycles are self-timed with max 5 ms duration and disable all inputs until completion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 8192 bits (1024 words × 8 bits), enabling storage of firmware config, sensor offsets, or device IDs |
| Supply Voltage Range | 2.7V to 5.5V - compatible with 3.3V and 5V logic domains without level shifting |
| I²C Clock Frequency | Up to 400 kHz at VCC ≥ 2.7V - supports faster parameter updates vs. 100 kHz legacy designs |
| Page Write Size | 16-byte pages - reduces I²C transaction count when writing multi-byte records like timestamps or calibration tables |
| Write Endurance | 1 million cycles - suitable for daily field calibration or event-logging applications over 10+ years |
| Data Retention | 100 years at +25°C - ensures long-term reliability in unpowered storage scenarios (e.g., battery-backed modules) |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade embedded control and automotive body electronics |
Pinout & Package
AT24C08N-10SI-2.7 is supplied in an 8-lead JEDEC-standard SOIC package (8S1), 0.150" wide, with gull-wing leads and 1.27 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0 | Device Address Input | No-connect for AT24C08; unused in address decoding - must be left floating or tied to GND/VCC per layout constraints |
| A1 | Device Address Input | No-connect for AT24C08; unused - no impact on I²C addressing or bus loading |
| A2 | Device Address Input | Hard-wired address bit - determines one of two possible I²C addresses (0x50 or 0x51) on shared bus |
| GND | Ground Reference | Return path for VCC and I/O signals; requires low-impedance connection to system ground plane |
| VCC | Power Supply | 2.7–5.5V supply input; decoupling capacitor (0.1 µF ceramic) required within 5 mm of pin |
| WP | Write Protect Control | Active-high hardware lock - ties to VCC to block all writes; ties to GND for normal read/write operation |
| SCL | I²C Clock Input | Positive-edge sampled clock; requires external pull-up (typically 2.2–10 kΩ) to VCC |
| SDA | I²C Data I/O | Open-drain bidirectional line; shares pull-up with other I²C devices on same bus segment |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Enables robust operation in noisy industrial environments by rejecting sub-threshold voltage transients on SCL/SDA/WP |
| 16-byte page write | Reduces I²C overhead by up to 87% vs. byte-wise writes when storing structured data (e.g., 12-byte sensor packet) |
| Hardware write protection | Prevents accidental overwrites during firmware updates or brown-out conditions without software intervention |
| 100-year data retention | Eliminates need for periodic refresh or backup power in maintenance-free deployments (e.g., smart meters, remote sensors) |
| Extended temperature range | Validated operation from –40°C to +85°C supports deployment in harsh enclosures or under-hood automotive locations |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C08A-SSHM-T | Same 8K-bit capacity, SOIC-8, 2.7–5.5V, but newer revision with improved ESD rating (4 kV HBM) and tighter tWR spec (max 4.5 ms) | Preferred for new designs per Microchip's notice; identical pinout and protocol compatibility | Select when designing new products requiring latest qualification and enhanced robustness |
| 24LC08BT-I/SN | Microchip 8K EEPROM in SOIC-8, 2.5–5.5V, 400 kHz, but rated only to +85°C (not extended temp); WP pin functional | Lacks extended temperature validation; not qualified for automotive or industrial high-temp zones | Acceptable for commercial-grade applications where ambient stays below 70°C |
Compared with AT24C08N-10SI-2.7, AT24C08A-SSHM-T offers improved reliability for new designs, while 24LC08BT-I/SN provides cost parity but sacrifices extended temperature assurance - choose based on qualification scope and lifecycle stage.

FAQ
What is the maximum I²C clock frequency supported by AT24C08N-10SI-2.7?
The AT24C08N-10SI-2.7 supports up to 400 kHz I²C clock frequency when VCC is 2.7V or higher. At 1.8V operation (not applicable to this -2.7 variant), it is limited to 100 kHz. The 400 kHz capability enables faster configuration loads and reduces bus occupancy time in multi-device systems.
Does AT24C08N-10SI-2.7 require external pull-up resistors on SDA and SCL lines?
Yes, AT24C08N-10SI-2.7 requires external pull-up resistors on both SDA and SCL lines because its I²C interface uses open-drain outputs. Typical values range from 2.2 kΩ to 10 kΩ to VCC, selected based on bus capacitance and desired rise time - critical for meeting tR/tF timing requirements in 400 kHz operation.
How many unique I²C addresses can be assigned to AT24C08N-10SI-2.7 on a shared bus?
AT24C08N-10SI-2.7 supports two unique I²C addresses: 0x50 and 0x51. Only the A2 pin is used for device addressing (A0 and A1 are no-connect), allowing two devices on the same bus. This simplifies multi-EEPROM architectures while avoiding address conflicts in compact designs.
What happens to AT24C08N-10SI-2.7 during a power interruption mid-write cycle?
If power fails during an AT24C08N-10SI-2.7 write cycle, the internal state is undefined and the affected byte or page may contain invalid data. The device includes a memory reset procedure (clock 9 cycles, detect SDA high, issue START) to recover bus communication - but data integrity requires external supervision or write-verify protocols.
Is AT24C08N-10SI-2.7 pin-compatible with AT24C08A-SSHM-T?
Yes, AT24C08N-10SI-2.7 is pin-compatible with AT24C08A-SSHM-T: both use 8-lead SOIC packages with identical pinout (A0/A1/NC, A2, GND, VCC, WP, SCL, SDA). They share the same footprint, solder profile, and PCB layout - enabling drop-in replacement where qualification allows.
