Product details
Overview
AT24C16N-10SI-2.7 from Microchip Technology (formerly Atmel) is a 16-kbit serial EEPROM IC with I²C-compatible 2-wire interface, organized as 2048 × 8-bit memory, operating from 2.7V to 5.5V, featuring 16-byte page write capability, 100-year data retention, and 1 million write cycles. It serves as nonvolatile configuration storage in embedded controllers, power management units, and sensor calibration modules.
For engineers reviewing the AT24C16N-10SI-2.7 datasheet, AT24C16N-10SI-2.7 pinout, AT24C16N-10SI-2.7 application, or AT24C16N-10SI-2.7 equivalent, key selection criteria include industrial temperature range (–40°C to +85°C), JEDEC SOIC-8 package compatibility, hardware write protection via WP pin, and 400 kHz I²C speed at ≥2.7V supply.
Technical Context
The AT24C16N-10SI-2.7 implements a standard I²C protocol with Schmitt-triggered, noise-filtered SDA/SCL inputs, supporting bidirectional data transfer and acknowledge polling during internal write cycles. Its memory architecture uses 128 pages of 16 bytes each, requiring an 11-bit word address for random access.
Unlike smaller family members, the AT24C16N-10SI-2.7 omits A0–A2 device address pins (NC), limiting bus addressing to a single instance per I²C segment; WP pin enables full-array hardware write protection when tied to VCC, and standby current is 1.6 µA typical at 2.7V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 16 Kbit (2048 × 8-bit), sufficient for firmware revision logs, calibration coefficients, and device identity storage in resource-constrained systems. |
| Supply Voltage Range | 2.7V to 5.5V - supports direct interfacing with 3.3V and 5V microcontrollers without level shifting. |
| I²C Clock Frequency | Up to 400 kHz at 2.7V+ - enables faster configuration writes versus 100 kHz legacy mode, reducing boot-time latency. |
| Write Cycle Time | Max 5 ms - defines minimum interval between successive write commands; impacts real-time logging throughput. |
| Data Retention | 100 years at 25°C - ensures long-term reliability for infrequently updated settings in industrial equipment. |
| Endurance | 1 million write cycles per byte - supports frequent recalibration or event logging in monitoring applications. |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade deployment in motor drives, PLCs, and outdoor IoT nodes. |
Pinout & Package
AT24C16N-10SI-2.7 is housed in an 8-lead JEDEC SOIC (8S1) package, 0.150" wide, with gull-wing leads, RoHS-compliant and halogen-free. Pin 1 is marked by a notch or dot; package dimensions: 4.90 mm × 3.90 mm × 1.75 mm max height.
| 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 buses. |
| SDA | Serial Data I/O | Open-drain bidirectional line; requires external pull-up resistor (typically 2.2–10 kΩ) to VCC for proper I²C signaling. |
| SCL | Serial Clock Input | Positive-edge clock input controlling data sampling; tolerant of noise due to integrated Schmitt trigger and filtering. |
| WP | Write Protect | Hardware lock: tied to VCC → full-array write disable; tied to GND → normal read/write operation. |
| GND | Ground Reference | System ground return path; must be low-impedance and co-located with MCU ground for noise immunity. |
| VCC | Power Supply | Primary supply input (2.7–5.5V); decoupling capacitor (0.1 µF ceramic) required within 5 mm of pin for stable operation. |
Key Features
| Feature | Design Value |
|---|---|
| 16-byte page write mode | Reduces I²C transaction overhead by up to 16× vs. byte writes, accelerating bulk configuration updates. |
| Schmitt-triggered, filtered inputs | Enables reliable operation in electrically noisy environments (e.g., motor control boards) without external RC filters. |
| Hardware write protection (WP pin) | Prevents accidental overwrites during firmware updates or brown-out conditions without software intervention. |
| Self-timed write cycle (5 ms max) | Eliminates need for host MCU to poll status registers - simplifies driver code and improves deterministic timing. |
| 100-year data retention | Guarantees persistent storage integrity across product lifecycle without battery backup or refresh mechanisms. |

FAQ
What is the maximum I²C clock frequency supported by AT24C16N-10SI-2.7?
The AT24C16N-10SI-2.7 supports up to 400 kHz I²C clock frequency when operated at VCC ≥ 2.7V. At 1.8V operation (not applicable to this -2.7 suffix variant), it is rated for 100 kHz. This 400 kHz capability enables faster configuration writes compared to legacy 100 kHz EEPROMs, reducing system initialization time in AT24C16N-10SI-2.7-based designs.
Does AT24C16N-10SI-2.7 require external pull-up resistors on SDA and SCL lines?
Yes, AT24C16N-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 depending on bus capacitance and desired rise time; 4.7 kΩ is commonly used with 3.3V VCC and ≤400 pF total bus load in AT24C16N-10SI-2.7 implementations.
How does the Write Protect (WP) pin function on AT24C16N-10SI-2.7?
On AT24C16N-10SI-2.7, the WP pin provides hardware-level write protection: when tied to VCC, all write operations (byte and page) to the entire 16K memory array are disabled; when tied to GND, normal read/write functionality is enabled. This feature prevents accidental corruption during power transients or software errors in AT24C16N-10SI-2.7 deployments.
What is the memory organization of AT24C16N-10SI-2.7?
The AT24C16N-10SI-2.7 is internally organized as 2048 words of 8 bits each (16,384 total bits), structured into 128 pages of 16 bytes. This arrangement supports efficient 16-byte page writes and requires an 11-bit data word address for random access - a key architectural detail affecting address pointer handling in AT24C16N-10SI-2.7 firmware drivers.
Is AT24C16N-10SI-2.7 compatible with newer AT24C16A variants?
Yes, AT24C16N-10SI-2.7 is pin-compatible and functionally equivalent to AT24C16A-10SI-2.7, with identical SOIC-8 footprint, electrical specifications, and command set. However, Microchip recommends AT24C16A-10SI-2.7 for new designs due to enhanced ESD performance (4 kV HBM) and extended qualification - both parts operate identically in existing AT24C16N-10SI-2.7 circuits.
