Product details
Overview
AT24C08N-10SC-1.8 from Microchip Technology (formerly Atmel) is an 8K-bit (1024 × 8) I²C-compatible serial EEPROM optimized for ultra-low-voltage embedded systems. It operates from 1.8V to 5.5V, supports 100 kHz I²C bus speed at 1.8V, features hardware write protection via WP pin, and delivers 1 million write cycles with 100-year data retention. It is used in battery-powered IoT sensors for nonvolatile configuration storage.
For engineers reviewing the AT24C08N-10SC-1.8 datasheet, AT24C08N-10SC-1.8 pinout, AT24C08N-10SC-1.8 application, or AT24C08N-10SC-1.8 equivalent, key selection factors include its 1.8V minimum supply, 16-byte page write capability, SOIC-8 package compatibility, and industrial temperature range (−40°C to +85°C).
Technical Context
The AT24C08N-10SC-1.8 implements a standard two-wire I²C interface with open-drain SDA/SCL pins, Schmitt-trigger inputs for noise immunity, and bi-directional data transfer protocol. Its internal architecture organizes memory 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 I²C bus. Write protection is controlled exclusively by the WP pin - tied to VCC to lock the full 8K array, or 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 firmware parameter storage in resource-constrained microcontrollers. |
| Supply Voltage Range | 1.8V to 5.5V - supports direct interfacing with 1.8V logic families and mixed-voltage systems without level shifters. |
| I²C Clock Frequency | 100 kHz max at 1.8V - ensures reliable communication in low-power sleep modes while maintaining timing margin per I²C spec. |
| Write Cycle Time | 10 ms maximum - defines worst-case latency for persistent state updates; requires polling or timeout handling in host firmware. |
| Endurance & Retention | 1 million write cycles / 100 years data retention - qualifies for long-life deployments in field-upgradable industrial controllers. |
| Operating Temperature | −40°C to +85°C - certified for use in automotive body electronics and outdoor environmental monitoring nodes. |
| Package | 8-lead JEDEC SOIC (8S1), 3.9mm × 4.9mm footprint - compatible with standard reflow profiles and automated PCB assembly. |
Pinout & Package
AT24C08N-10SC-1.8 is housed in an 8-lead JEDEC-standard SOIC package (package code 8S1), measuring 3.9 mm × 4.9 mm × 1.75 mm, with gull-wing leads and 1.27 mm pitch. Pin 1 is marked by a beveled corner or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0 | No Connect (NC) | Not bonded internally; must be left floating or tied to GND/VCC - no effect on device addressing. |
| A1 | No Connect (NC) | Not bonded internally; no electrical function - eliminates routing complexity in multi-device I²C networks. |
| A2 | Device Address Input | Hardwired address bit; selects one of two possible addresses (0x50 or 0x51) on shared I²C bus. |
| GND | Ground Reference | Return path for all internal circuitry; must be low-impedance connection to system ground plane. |
| VCC | Power Supply | Accepts 1.8–5.5V; bypass capacitor (0.1 µF ceramic) required within 5 mm for stable I²C timing. |
| WP | Write Protect Control | Active-high hardware lock: VCC = full-array protection; GND = full read/write access. |
| SCL | Serial Clock Input | Open-drain input synchronized to host MCU clock; requires external pull-up (typically 4.7 kΩ to VCC). |
| SDA | Serial Data I/O | Open-drain bidirectional line; shares pull-up with SCL; supports multi-master arbitration per I²C standard. |
Key Features
| Feature | Design Value |
|---|---|
| 1.8V Operation | Enables direct integration with 1.8V SoCs and ultra-low-power MCUs without voltage translation circuitry. |
| 16-byte Page Write | Reduces I²C transaction overhead by up to 15× vs. byte-write mode - critical for rapid calibration data logging. |
| Schmitt-trigger Inputs | Rejects >100 ns noise pulses on SDA/SCL lines - improves robustness in electrically noisy motor-control or power-supply environments. |
| Hardware Write Protection | Prevents accidental overwrites during brown-out or firmware glitches - eliminates need for software-based lock mechanisms. |
| Industrial Temperature Range | Validated operation from −40°C to +85°C - supports deployment in under-hood automotive modules and outdoor edge gateways. |

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, 1.7V–5.5V supply, but TSSOP-8 package (8T) and −40°C to +125°C grade. | Targeted for under-hood automotive use where extended temperature is mandatory. | Select when operating beyond +85°C or requiring smaller 3mm × 4.4mm footprint. |
| M24C08-RMN6TP | 8K-bit STMicro EEPROM; 1.8V–5.5V, 100 kHz @ 1.8V, SOIC-8, but only 400k write cycles and 40-year retention. | Suitable for cost-sensitive consumer products with shorter service life expectations. | Choose for lower-cost alternatives where 1M/100y specs are not required. |
Compared with AT24C08N-10SC-1.8, AT24C08D-SSHM-T offers wider temperature tolerance and smaller size but lacks the same industrial-grade qualification documentation, while M24C08-RMN6TP trades endurance and retention for unit cost reduction - making AT24C08N-10SC-1.8 optimal for long-life, mission-critical industrial designs.

FAQ
What is the minimum operating voltage for AT24C08N-10SC-1.8?
The AT24C08N-10SC-1.8 supports true 1.8V operation, with guaranteed functionality down to 1.8V across the full industrial temperature range (−40°C to +85°C). Its DC characteristics - including 100 kHz I²C timing and 10 ms write cycle - are fully specified at VCC = 1.8V, eliminating need for voltage boosting in ultra-low-power designs.
How many devices can share the same I²C bus with AT24C08N-10SC-1.8?
Up to two AT24C08N-10SC-1.8 devices can operate on a single I²C bus. This is because only the A2 pin is functional for device addressing (A0 and A1 are NC), yielding two possible 7-bit addresses: 0x50 and 0x51. Each device must have A2 hardwired uniquely (GND or VCC) to avoid address collision.
Does AT24C08N-10SC-1.8 support partial page writes?
Yes, AT24C08N-10SC-1.8 supports partial page writes: the host may transmit 1–16 bytes within a single page boundary (16-byte alignment), and the EEPROM automatically increments the internal address pointer. Bytes beyond the current page boundary wrap to the start of the same page - a behavior explicitly documented in the datasheet's Page Write section.
What is the function of the WP pin on AT24C08N-10SC-1.8?
The WP (Write Protect) pin on AT24C08N-10SC-1.8 is an active-high hardware lock. When pulled to VCC, it disables all write operations to the entire 8K-bit memory array. When tied to GND, full read/write access is enabled. No software command or I²C transaction can override this physical protection - critical for safeguarding calibration or security keys.
Is AT24C08N-10SC-1.8 RoHS compliant and lead-free?
Yes, AT24C08N-10SC-1.8 is RoHS compliant and lead-free. The "N" suffix in the part number denotes lead-free (Pb-free) packaging per Microchip's standard product marking convention, and the SOIC-8 (8S1) package uses matte tin lead finish. Full compliance documentation is available in Microchip's official PCN and material declarations.
