Product details
Overview
AT24C16N-10SC-2.7 from Microchip Technology (formerly Atmel) is a 16-kbit I²C-compatible serial EEPROM organized as 2048 × 8 bits, operating from 2.7V to 5.5V, with 100 kHz clock support, 16-byte page write capability, and hardware write protection via the WP pin. It serves as nonvolatile configuration storage in embedded controllers, power management units, and sensor calibration modules.
For engineers reviewing the AT24C16N-10SC-2.7 datasheet, AT24C16N-10SC-2.7 pinout, AT24C16N-10SC-2.7 application, or AT24C16N-10SC-2.7 equivalent, key selection criteria include low-voltage operation down to 2.7V, 100-year data retention, 1 million write cycles, JEDEC SOIC-8 packaging, and I²C bus compatibility with Schmitt-trigger noise filtering.
Technical Context
The AT24C16N-10SC-2.7 implements a two-wire I²C interface with open-drain SDA/SCL pins, supports standard-mode (100 kHz) timing at 2.7V–5.5V, and uses address-less device addressing-A0/A1/A2 are NC, limiting bus topology to one AT24C16 per I²C segment. Its internal architecture features 128 pages of 16 bytes each, requiring an 11-bit word address for random access.
Write operations include byte and 16-byte page modes with self-timed internal write cycles (≤10 ms), while read modes support current-address, random-address, and sequential reads. Standby current is 1.6 µA max at 2.7V, and inputs include Schmitt-triggered, noise-filtered logic with 100 ns suppression time.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 16 Kbit (2048 × 8 bits), enabling storage of firmware flags, calibration coefficients, or device IDs in space-constrained systems |
| 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 maximum at 2.7V - ensures reliable communication in electrically noisy industrial environments |
| Page Write Size | 16 bytes per page - reduces I²C transaction overhead when updating parameter blocks or lookup tables |
| Data Retention | 100 years - guarantees long-term integrity of stored settings across product lifecycles without refresh |
| Endurance | 1 million write cycles - accommodates frequent logging or runtime configuration updates in telemetry or control applications |
| Standby Current | 1.6 µA max at 2.7V - minimizes quiescent power in battery-backed or energy-harvesting systems |
Pinout & Package
AT24C16N-10SC-2.7 is housed in an 8-lead JEDEC-standard SOIC package (8S1), 3.9mm × 4.9mm body, 1.27mm lead pitch, gull-wing leads, RoHS-compliant matte tin finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0, A1, A2 | No Connect (NC) | Not used for device addressing - eliminates external pull-up/down resistors and simplifies PCB layout for single-device I²C nodes |
| GND | Ground Reference | Common return path for VCC and I/O signals; must be low-impedance to maintain noise immunity on SDA/SCL lines |
| VCC | Power Supply | Primary supply input (2.7–5.5V); decoupling capacitor (0.1 µF ceramic) required within 5 mm of pin |
| WP | Write Protect Control | Hardware-enforced write lock: tied to GND for normal operation, VCC to disable all writes including page and byte modes |
| SCL | Serial Clock Input | Positive-edge sampled clock; requires external pull-up resistor (typically 4.7 kΩ) to VCC for I²C bus compliance |
| SDA | Serial Data I/O | Open-drain bidirectional line; shares pull-up with SCL; supports multi-master arbitration and wire-OR logic |
Key Features
| Feature | Design Value |
|---|---|
| Low-voltage operation (2.7V–5.5V) | Enables direct integration with 3.3V logic families and mixed-voltage systems without voltage translators |
| 16-byte page write mode | Reduces I²C bus occupancy by up to 87% vs. byte writes when storing contiguous data such as sensor calibration arrays |
| Schmitt-trigger, filtered inputs | Rejects >100 ns noise spikes on SDA/SCL, eliminating external RC filters in industrial motor-control or power-supply designs |
| Hardware write protection (WP pin) | Prevents accidental overwrites during firmware updates or brown-out conditions - no software dependency required |
| 100-year data retention | Eliminates need for periodic refresh or backup power in infrastructure monitoring devices deployed for decades |

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 16Kbit capacity, 2.5V–5.5V range, TSSOP-8 package, 100 kHz max at 2.5V; A0/A1/A2 remain NC | TSSOP-8 footprint requires PCB redesign; slightly lower standby current (1.4 µA @ 2.5V) but identical timing and endurance | Select when board space is constrained and TSSOP assembly is already supported in production. |
| M24C16-WMN6TP | 16Kbit, 1.7V–5.5V range, SOIC-8, 400 kHz I²C at ≥2.5V; A0/A1/A2 functional for multi-device addressing | Supports up to 8 devices on same bus; higher speed at 3.3V/5V but incompatible pin-level addressing scheme with AT24C16N-10SC-2.7 | Choose for scalable multi-node I²C topologies where bus expansion is anticipated, accepting minor firmware adaptation. |
Compared with AT24C16D-SSHM-T and M24C16-WMN6TP, the AT24C16N-10SC-2.7 offers guaranteed 2.7V–5.5V operation with fixed single-device addressing - ideal for cost-sensitive, single-EEPROM designs where layout simplicity and voltage margin outweigh bus scalability or ultra-low-power needs.

FAQ
What is the maximum I²C clock frequency supported by the AT24C16N-10SC-2.7?
The AT24C16N-10SC-2.7 supports up to 100 kHz I²C clock frequency when operated within its 2.7V–5.5V supply range. This is specified in the AC Characteristics table under fSCL for 2.7V, 2.5V, and 1.8V versions. It does not support 400 kHz operation - that rating applies only to the 5.0V variant (e.g., AT24C16-10SC).
Is the AT24C16N-10SC-2.7 pin-compatible with other AT24Cxx EEPROMs in SOIC-8 packages?
Yes, the AT24C16N-10SC-2.7 shares the same 8-lead JEDEC SOIC (8S1) package and pinout as AT24C01A/02/04/08/16 variants. However, A0/A1/A2 are NC on AT24C16N-10SC-2.7, whereas they serve as address inputs on smaller-density parts - firmware must account for this difference in device addressing.
Does the AT24C16N-10SC-2.7 require external pull-up resistors on SDA and SCL lines?
Yes, the AT24C16N-10SC-2.7 requires external pull-up resistors on both SDA and SCL lines, as both pins are open-drain. Typical values are 4.7 kΩ to VCC; exact value depends on bus capacitance and desired rise time - refer to I²C bus specification guidelines for your system's trace length and node count.
How does the Write Protect (WP) pin function on the AT24C16N-10SC-2.7?
When the WP pin is tied to VCC, all write operations (byte and page) to the AT24C16N-10SC-2.7 are disabled - only read operations are permitted. When WP is grounded, full read/write functionality is enabled. No internal pull-up or pull-down exists; the pin must be actively driven.
What is the endurance and data retention specification for the AT24C16N-10SC-2.7?
The AT24C16N-10SC-2.7 is rated for 1 million write/erase cycles per memory location and guarantees 100 years of data retention at +25°C ambient. These values are characterized and documented in the DC Characteristics and Endurance sections of the official Microchip datasheet (Rev. 0180F).
