Product details
Overview
AT24C16N-10SC-1.8 from Microchip Technology (formerly Atmel) is a 16-Kbit (2048 × 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 AT24C16N-10SC-1.8 datasheet, AT24C16N-10SC-1.8 pinout, AT24C16N-10SC-1.8 application, or AT24C16N-10SC-1.8 equivalent, key selection considerations include its 1.8V minimum supply, 16-byte page write capability, JEDEC SOIC-8 package, and absence of device address pins (A0–A2 are NC), enabling single-device I²C bus deployment without address conflict.
Technical Context
The AT24C16N-10SC-1.8 implements a two-wire I²C interface with Schmitt-triggered, noise-filtered SDA/SCL inputs and open-drain SDA output compatible with standard I²C bus topology. Its internal memory is organized as 128 pages × 16 bytes, requiring an 11-bit word address for random access.
Write protection is enforced exclusively through the WP pin: tied to VCC, it locks the entire 16K array; tied to GND, full read/write access is enabled. The device enters low-power standby mode after STOP condition receipt or power-up, drawing only 3 µA typical at 1.8V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 16 Kbit (2048 × 8 bits), sufficient for storing firmware calibration tables or device identity parameters |
| Supply Voltage Range | 1.8V to 5.5V - enables direct interfacing with 1.8V logic microcontrollers without level shifting |
| I²C Clock Frequency | 100 kHz max at 1.8V - ensures reliable timing margin in low-power, noise-prone environments |
| Page Write Size | 16-byte pages - reduces I²C transaction count when updating multi-byte configuration blocks |
| Write Endurance | 1 million cycles - supports frequent runtime parameter logging in industrial monitoring nodes |
| Data Retention | 100 years at +25°C - guarantees long-term validity of stored cryptographic keys or calibration coefficients |
| Standby Current | 3 µA typical at 1.8V - minimizes quiescent power in always-on edge devices |
Pinout & Package
AT24C16N-10SC-1.8 is housed in an 8-lead JEDEC SOIC package (8S1), 0.150" wide, with standard gull-wing leads and 1.27 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0, A1, A2 | Device Address Inputs | No-connect (NC) - eliminates external pull-up/down resistors and simplifies single-device bus design |
| SDA | Serial Data I/O | Open-drain bidirectional line - requires external pull-up; supports wired-AND with other I²C peripherals |
| SCL | Serial Clock Input | Input-only clock line - synchronizes all data transfers; Schmitt trigger ensures noise immunity |
| WP | Write Protect | Hardware lock control - VCC = full-array protection; GND = full read/write access |
| VCC | Power Supply | 1.8V–5.5V input - powers internal logic and memory array; no separate VIO required |
| GND | Ground Reference | Return path for all internal circuits and I/O - must be low-impedance for stable I²C signaling |
Key Features
| Feature | Design Value |
|---|---|
| 1.8V operation support | Enables direct integration with modern ultra-low-power MCUs (e.g., ARM Cortex-M0+), eliminating voltage translation circuitry |
| 16-byte page write | Reduces I²C overhead by up to 94% vs. byte-write for 16-byte updates, improving system responsiveness |
| Hardware write protection (WP) | Prevents accidental overwrites during firmware updates or brown-out conditions without software intervention |
| 100-year data retention | Ensures persistent storage of critical device identifiers or security credentials across product lifetime without refresh |
| Schmitt-trigger inputs | Rejects fast transient noise on SDA/SCL lines, increasing robustness in electrically noisy industrial enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C16D-SSHM-T | Same 16K capacity, 1.7V–5.5V range, TSSOP-8 package; A0–A2 pins functional (supports multi-device bus) | Requires address pin configuration; suited for systems needing >1 EEPROM on same I²C bus | Select if bus scalability is required; not drop-in due to pin function and package difference |
| M24C16-WMN6TP | 16K I²C EEPROM, 1.8V–5.5V, SOIC-8, but rated for automotive AEC-Q100 Grade 2 (−40°C to +105°C) | Higher temperature rating and qualification - appropriate for under-hood or dashboard modules | Choose for automotive-critical applications where extended temperature validation is mandatory |
Compared with AT24C16N-10SC-1.8, AT24C16D-SSHM-T adds device addressing flexibility at the cost of pin compatibility, while M24C16-WMN6TP trades broader industrial qualification for automotive-grade reliability - both require layout review and firmware address mapping updates.

FAQ
What is the minimum operating voltage for AT24C16N-10SC-1.8?
The AT24C16N-10SC-1.8 supports true 1.8V operation, with a specified minimum supply voltage of 1.8V and maximum of 5.5V. This allows direct connection to 1.8V I/O domains of modern microcontrollers without level-shifting circuitry, and its 100 kHz I²C speed is guaranteed across this full voltage range.
Does AT24C16N-10SC-1.8 support multi-device I²C bus configurations?
No - AT24C16N-10SC-1.8 has A0, A1, and A2 pins designated as no-connect (NC), meaning it uses a fixed I²C device address and supports only one instance per bus. For multi-device configurations, consider AT24C16D-SSHM-T, which implements functional address pins and supports up to eight devices on the same bus.
How does the WP pin function on AT24C16N-10SC-1.8?
On AT24C16N-10SC-1.8, the WP pin provides hardware-level write protection: when pulled high to VCC, the entire 16K memory array is locked against writes; when pulled low to GND, full read and write access is enabled. This behavior is independent of I²C commands and remains active during power transitions.
What is the page write size and maximum write cycle time for AT24C16N-10SC-1.8?
AT24C16N-10SC-1.8 supports 16-byte page writes, allowing up to 16 bytes to be written in a single I²C transaction. Its maximum self-timed write cycle duration is 10 ms, during which all inputs are disabled and the device does not acknowledge I²C traffic until completion.
Is AT24C16N-10SC-1.8 qualified for automotive applications?
AT24C16N-10SC-1.8 is rated for industrial temperature range (−40°C to +85°C) and is not AEC-Q100 qualified. For automotive applications requiring formal qualification, Microchip offers the AT24C16C variant, and STMicroelectronics provides the AEC-Q100-certified M24C16-WMN6TP as a verified alternative to AT24C16N-10SC-1.8.
