Product details
Overview
AT24C08-10PC-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 communication, features hardware write protection via the WP pin, and delivers 1 million write cycles with 100-year data retention - used in industrial sensor calibration storage and power-meter firmware parameter backup.
For engineers reviewing the AT24C08-10PC-2.7 datasheet, AT24C08-10PC-2.7 pinout, AT24C08-10PC-2.7 application, or AT24C08-10PC-2.7 equivalent, key selection criteria include its 2.7V–5.5V supply range, 16-byte page write capability, SOIC-8 package compatibility, and I²C address configuration using A2 only (A0/A1 = NC).
Technical Context
The AT24C08-10PC-2.7 implements a standard I²C-compatible 2-wire interface with Schmitt-triggered, noise-filtered SDA/SCL inputs. Its internal architecture organizes memory as 64 pages of 16 bytes each, requiring a 10-bit data word address for random access.
Device addressing uses only the A2 pin (A0 and A1 are no-connect), enabling up to two AT24C08 devices on a single bus. Write protection is controlled exclusively by the WP pin: tied to VCC for full-array lock, GND for normal read/write operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 8 Kbit (1024 × 8 bits), organized as 64 pages × 16 bytes - enables efficient parameter block storage without external address latching. |
| Supply Voltage Range | 2.7V to 5.5V - supports direct interfacing with 3.3V microcontrollers and legacy 5V systems without level shifting. |
| I²C Clock Frequency | 100 kHz max at 2.7V - ensures reliable timing margin in noisy industrial environments with long trace runs. |
| Write Cycle Time | 10 ms maximum - defines minimum delay between write commands; impacts firmware update latency in host software. |
| Endurance & Retention | 1 million write cycles / 100 years data retention - qualifies for decade-long field deployment in utility metering and automotive subsystems. |
| Standby Current | 4 µA max at 2.7V - enables ultra-low-power operation in battery-backed real-time clock (RTC) modules and portable diagnostics tools. |
| Package | 8-lead JEDEC SOIC (8S1) - industry-standard footprint compatible with automated PCB assembly and thermal reflow profiles. |
Pinout & Package
AT24C08-10PC-2.7 is supplied in an 8-lead JEDEC SOIC package (8S1), measuring 3.99 mm × 4.98 mm × 1.73 mm, with gull-wing leads and 1.27 mm pitch. Pin 1 is marked by a beveled corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0 | No Connect | Not bonded internally; must be left unconnected - eliminates address ambiguity in multi-device I²C networks. |
| A1 | No Connect | Not bonded internally; floating or tied does not affect device behavior - simplifies PCB layout routing. |
| A2 | Device Address Input | Hardwired input determining LSB of 7-bit I²C slave address (0x50 or 0x51); enables dual-device addressing on one bus. |
| GND | Ground Reference | Return path for VCC and signal currents; requires low-impedance connection to system ground plane to minimize I²C noise coupling. |
| VCC | Power Supply | Primary DC supply (2.7–5.5V); decoupling capacitor (0.1 µF ceramic) required within 5 mm for stable I²C operation. |
| WP | Write Protect Control | Active-high hardware lock: VCC = full-array write disable; GND = full read/write access - critical for firmware integrity during field updates. |
| SCL | Serial Clock Input | Open-drain input synchronized to master clock; requires external pull-up (typically 4.7 kΩ) to VCC for proper I²C timing compliance. |
| SDA | Serial Data I/O | Bi-directional open-drain data line shared across I²C bus; same pull-up requirement as SCL; supports multi-master arbitration. |
Key Features
| Feature | Design Value |
|---|---|
| 16-byte Page Write Mode | Enables burst programming of calibration coefficients or configuration blocks with single I²C transaction - reduces host CPU overhead by 87% vs. byte-wise writes. |
| Schmitt Trigger Inputs | Provides >0.4V hysteresis on SDA/SCL - rejects EMI-induced glitches in motor-drive or switching-power-supply adjacent layouts. |
| Hardware Write Protection | WP pin disables all write operations when pulled high - prevents accidental overwrites during brown-out or reset sequences in safety-critical systems. |
| 100-Year Data Retention | Validated at 85°C operating temperature - guarantees parameter persistence across full product lifecycle without refresh logic. |
| Industrial Temperature Range | Specified from –40°C to +85°C (Commercial version rated 0°C to +70°C; this part is Commercial) - suitable for indoor industrial controllers and HVAC management units. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C08-10PI-2.7 | Identical electrical specs but rated for –40°C to +85°C industrial temperature range; same SOIC-8 package. | Required for outdoor or under-hood automotive/industrial deployments where ambient exceeds 70°C. | Select when extended temperature qualification is mandated - no PCB or firmware changes needed. |
| M24C08-RMN6TP | STMicroelectronics 8K I²C EEPROM; 1.7–5.5V supply; 400 kHz max clock at 5V; 16-byte page; WP pin; SOIC-8. | Higher speed at 5V (400 kHz vs. 100 kHz), but reduced noise immunity due to lack of Schmitt triggers on SDA/SCL. | Prefer for high-throughput data logging in 5V systems; verify timing margins if operating below 4.5V. |
Compared with AT24C08-10PC-2.7, the AT24C08-10PI-2.7 extends thermal reliability without altering design, while M24C08-RMN6TP trades noise robustness for higher bandwidth - both require validation of WP logic polarity and I²C address mapping in existing firmware.

FAQ
What is the I²C slave address of AT24C08-10PC-2.7?
The AT24C08-10PC-2.7 uses a 7-bit I²C address where the base is 0x50. The A2 pin determines the LSB: A2 = low → 0x50, A2 = high → 0x51. A0 and A1 are no-connect and do not affect addressing. This two-address capability allows two AT24C08-10PC-2.7 devices to coexist on the same I²C bus without conflict.
Can AT24C08-10PC-2.7 operate reliably at 3.3V?
Yes, AT24C08-10PC-2.7 is fully specified for 2.7V to 5.5V operation, including 3.3V nominal systems. At 3.3V, it supports 100 kHz I²C communication, draws ≤4 µA standby current, and maintains full 1 million write cycle endurance - making it ideal for 3.3V microcontroller interfaces without level shifters.
How does the WP pin function on AT24C08-10PC-2.7?
On AT24C08-10PC-2.7, the WP (Write Protect) pin is active-high: when tied to VCC, it disables all write operations to the entire memory array; when grounded, full read/write access is enabled. This hardware lock prevents accidental writes during power transitions or firmware errors - critical for preserving calibration data.
What is the maximum page write size for AT24C08-10PC-2.7?
AT24C08-10PC-2.7 supports 16-byte page writes. After sending the starting address and first byte, the internal address counter auto-increments for up to 15 additional bytes within the same 16-byte page boundary. Exceeding the page causes wraparound to the page start - a key constraint for firmware buffer management.
Is AT24C08-10PC-2.7 RoHS compliant and lead-free?
Yes, AT24C08-10PC-2.7 is RoHS compliant and manufactured with lead-free terminations per Microchip's standard specifications. The SOIC-8 package (8S1) uses matte tin plating and meets JEDEC J-STD-020 moisture sensitivity level 1 - suitable for standard reflow soldering without special handling.
