Product details
Overview
AT24C16-10TI-2.7 from Microchip Technology (formerly Atmel) is a 16-Kbit (2048 × 8) two-wire serial EEPROM optimized for low-voltage industrial applications. It operates from 2.7V to 5.5V, supports 400 kHz I²C bus speed at ≥2.7V, features hardware write protection via the WP pin, and delivers 1 million write cycles with 100-year data retention. It is used in embedded system configuration storage, sensor calibration data logging, and power-management parameter backup.
For engineers reviewing the AT24C16-10TI-2.7 datasheet, AT24C16-10TI-2.7 pinout, AT24C16-10TI-2.7 application, or AT24C16-10TI-2.7 equivalent, key selection considerations include its 16-byte page write capability, absence of device address pins (A0–A2 are NC), TSSOP-8 package footprint, automotive-grade temperature range (−40°C to +85°C), and compatibility with standard I²C protocol timing requirements.
Technical Context
The AT24C16-10TI-2.7 implements a fixed 16K-bit memory array organized as 128 pages × 16 bytes, requiring an 11-bit data word address. Its I²C interface uses open-drain SDA and edge-triggered SCL with Schmitt-trigger inputs for noise immunity, and supports standard-mode (100 kHz) and fast-mode (400 kHz) operation depending on VCC level.
Unlike smaller family members (e.g., AT24C01A/02), the AT24C16 does not use A0–A2 for device addressing - those pins are no-connect - limiting bus topology to one device per I²C segment. Write protection is implemented exclusively via the WP pin, which disables all writes when pulled high.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 16 Kbit (2048 × 8 bits), enabling storage of firmware flags, calibration coefficients, or user settings across 128 pages |
| Supply Voltage Range | 2.7V to 5.5V - compatible with 3.3V and 5V logic systems without level shifting |
| I²C Clock Frequency | 400 kHz maximum at VCC ≥ 2.7V - supports faster configuration reads/writes than 100 kHz legacy devices |
| Page Write Capacity | 16-byte page writes - reduces I²C transaction count vs. byte writes, improving efficiency in burst data updates |
| Endurance & Retention | 1 million write cycles / 100 years data retention - suitable for field-updatable systems with infrequent but critical writes |
| Operating Temperature | −40°C to +85°C - qualified for industrial and automotive under-hood control modules |
| Write Protect Function | Hardware-enabled via WP pin - prevents accidental overwrites during power transitions or firmware glitches |
Pinout & Package
AT24C16-10TI-2.7 is housed in an 8-lead Thin Shrink Small Outline Package (TSSOP), 3.0 mm × 4.4 mm body, 0.65 mm pitch, lead-free/halogen-free, compliant with JEDEC MO-153 Variation AA.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0 | No Connect | Not bonded; must be left floating or tied to GND/VCC - no effect on addressing or operation |
| A1 | No Connect | Not bonded; no impact on device behavior or I²C communication |
| A2 | No Connect | Not bonded; eliminates need for external address resistors in multi-device designs |
| GND | Ground Reference | Return path for VCC and I/O signals; requires low-impedance connection to system ground plane |
| VCC | Power Supply | 2.7V–5.5V supply input; decoupling capacitor (0.1 µF) recommended within 1 cm of pin |
| WP | Write Protect Input | Active-high enable: tied to VCC to lock memory; tied to GND for normal read/write access |
| SCL | I²C Clock Input | Positive-edge sampled clock; requires external pull-up resistor (typically 2.2–10 kΩ) |
| SDA | I²C Bidirectional Data | Open-drain output/input; shares bus with other I²C devices; requires same pull-up as SCL |
Key Features
| Feature | Design Value |
|---|---|
| 16-byte Page Write | Reduces I²C bus overhead by up to 94% vs. single-byte writes for block updates (e.g., sensor calibration tables) |
| Schmitt-trigger Inputs | Suppresses noise-induced false clock/data transitions in electrically noisy industrial environments |
| Hardware Write Protection | Eliminates software-based lock mechanisms, preventing corruption during brown-out or reset conditions |
| 11-bit Addressing | Supports full 2048-word random access without external address latching or bank switching logic |
| Low Standby Current | 1.6 µA typical at 2.7V - extends battery life in always-on IoT edge nodes and portable instrumentation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C16A-SSHM-T | Successor part with enhanced ESD rating (4 kV HBM), same 16K-bit organization and TSSOP-8 package | Preferred for new designs targeting long-term supply continuity and higher robustness in handling-sensitive environments | Select when designing for production beyond 2026; AT24C16-10TI-2.7 remains valid for legacy repair or existing BOMs |
| M24C16-WMN6TP | STMicroelectronics 16K I²C EEPROM in TSSOP-8; supports 1 MHz fast-mode plus, 1.7–5.5V operation | Better suited for mixed-voltage systems (e.g., 1.8V microcontrollers) and higher-speed polling scenarios | Choose if system requires 1.8V compatibility or >400 kHz throughput; pinout matches but WP functionality differs (active-low) |
Compared with AT24C16-10TI-2.7, the AT24C16A offers extended lifecycle assurance and improved ESD tolerance, while the M24C16-WMN6TP enables lower-voltage operation and faster bus speeds - both require validation of WP pin polarity and timing margins in existing firmware.

FAQ
What is the memory organization of the AT24C16-10TI-2.7?
The AT24C16-10TI-2.7 contains 16,384 bits organized as 2048 words × 8 bits, internally segmented into 128 pages of 16 bytes each. It uses an 11-bit data word address for random access, and page boundaries align to 16-byte offsets - essential for optimizing write efficiency in firmware that stores structured configuration data.
Does the AT24C16-10TI-2.7 support multi-device I²C bus configurations?
No - the AT24C16-10TI-2.7 has no functional device address pins (A0–A2 are NC), so only one instance can reside on a given I²C bus segment. This simplifies routing but requires bus isolation or multiplexing when multiple 16K EEPROMs are needed in a single system.
What is the function of the WP pin on the AT24C16-10TI-2.7?
The WP (Write Protect) pin on the AT24C16-10TI-2.7 is an active-high hardware lock: when pulled to VCC, it disables all write operations including byte, page, and erase commands; when grounded, full read/write access is enabled. This provides fail-safe protection against unintended memory modification.
Can the AT24C16-10TI-2.7 operate at 1.8V?
No - the AT24C16-10TI-2.7 is specified for 2.7V to 5.5V operation only. For 1.8V systems, Microchip recommends the AT24C16-10TI-1.8 variant, which shares identical pinout and functionality but is characterized down to 1.8V with reduced maximum clock frequency (100 kHz).
Is the AT24C16-10TI-2.7 suitable for automotive applications?
Yes - the AT24C16-10TI-2.7 is rated for −40°C to +85°C operation and meets automotive-grade reliability standards, including 1 million write cycles and 100-year data retention. It is commonly used in body control modules, infotainment configuration storage, and ADAS subsystem parameter backup.
