Product details
Overview
AT24C16A-10TI-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, featuring 128-page × 16-byte write architecture, 400 kHz clock rate at 2.7V, and hardware write protection via WP pin. It serves as nonvolatile configuration storage in microcontroller-based industrial control modules.
For engineers reviewing the AT24C16A-10TI-2.7 datasheet, AT24C16A-10TI-2.7 pinout, AT24C16A-10TI-2.7 application, or AT24C16A-10TI-2.7 equivalent, key selection criteria include 2.7V–5.5V supply compatibility, 16-byte page write capability, WP-enabled hardware data lock, 100-year data retention, and TSSOP-8 packaging for space-constrained PCB layouts.
Technical Context
The AT24C16A-10TI-2.7 implements a two-wire I²C interface with open-drain SDA and Schmitt-triggered SCL inputs for noise immunity. Its address decoding logic disables A0–A2 pins-making it single-device-per-bus-while supporting standard 7-bit device addressing with R/W bit.
Internally, it uses self-timed 5 ms write cycles with acknowledge polling support and supports byte-write, page-write (16-byte), current-address read, random-address read, and sequential read modes-all compliant with I²C protocol timing requirements at 400 kHz (2.7V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 16 Kbit (2048 × 8 bits), enabling storage of firmware calibration tables or device configuration profiles |
| Supply Voltage | 2.7V to 5.5V - compatible with 3.3V and 5V logic systems without level-shifting |
| Interface | I²C (2-wire serial) - reduces PCB routing complexity and pin count vs parallel EEPROMs |
| Write Cycle Time | Max 5 ms - defines minimum interval between successive writes; enables predictable timing in real-time systems |
| Endurance | 1 million write cycles - supports frequent parameter updates in logging or adaptive control applications |
| Data Retention | 100 years - ensures long-term reliability in unattended or maintenance-free deployments |
| Operating Temp | −40°C to +85°C - qualified for industrial ambient environments including factory automation equipment |
Pinout & Package
AT24C16A-10TI-2.7 is supplied in an 8-lead TSSOP package (JEDEC MO-153, variation AA), measuring 3.0 mm × 4.4 mm × 1.05 mm, with gull-wing leads and pin 1 indicator in bottom-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0, A1, A2 | No-connect (NC) | Not used for device addressing - limits bus to one AT24C16A per I²C segment |
| GND | Ground reference | Common return path for VCC and signal currents; must be low-impedance for noise immunity |
| VCC | Power supply input | Accepts 2.7V–5.5V; decoupling capacitor required within 10 mm for stable operation |
| WP | Write Protect control | Pulled high to VCC to lock full 16K array; grounded for normal read/write access |
| SCL | Serial Clock input | Positive-edge sampled clock; requires external pull-up; supports 400 kHz max at 2.7V |
| SDA | Serial Data bidirectional I/O | Open-drain output; shared across multiple I²C devices; requires external pull-up resistor |
Key Features
| Feature | Design Value |
|---|---|
| Hardware Write Protection | WP pin disables all writes when tied to VCC - prevents accidental overwrites during power transients or firmware bugs |
| 16-byte Page Write | Enables efficient bulk storage of sensor calibration blocks or parameter sets without inter-byte delays |
| Schmitt Trigger Inputs | Filters noise on SCL/SDA lines - improves robustness in electrically noisy industrial enclosures |
| 100-Year Data Retention | Eliminates need for periodic refresh or backup power in battery-less embedded systems |
| Industrial Temperature Range | Validated operation from −40°C to +85°C - suitable for DIN-rail mounted PLC I/O modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STMicroelectronics M24C16-WMN6TP | Same 16Kbit size, 2.5–5.5V range, TSSOP-8, but rated for 400 kHz only at ≥2.5V; no 2.7V-specific timing guarantee | Requires validation at 2.7V operation; lacks explicit 2.7V AC characterization in datasheet | Prefer AT24C16A-10TI-2.7 when guaranteed 400 kHz performance at 2.7V is required |
| ON Semiconductor CAT24C16WI-GT3 | 16Kbit, 1.7–5.5V, TSSOP-8, 400 kHz at 2.7V; endurance rated at 1M cycles but data retention specified as 40 years | Lower retention spec may impact long-life deployments; wider voltage range adds flexibility in mixed-supply systems | Select CAT24C16WI-GT3 only if 1.7–2.7V operation is needed; otherwise AT24C16A-10TI-2.7 offers superior longevity assurance |
Compared with M24C16-WMN6TP and CAT24C16WI-GT3, AT24C16A-10TI-2.7 uniquely guarantees 400 kHz I²C operation at 2.7V and delivers 100-year data retention - critical for industrial infrastructure and medical devices where field replacement is costly or impractical.

FAQ
What is the maximum I²C clock frequency supported by AT24C16A-10TI-2.7 at 2.7V?
AT24C16A-10TI-2.7 supports up to 400 kHz I²C clock frequency at 2.7V, as explicitly characterized in the AC Electrical Characteristics table. This is confirmed for both standard-mode and fast-mode timing compliance under VCC = 2.7V conditions, unlike some competing 16K EEPROMs that only guarantee 400 kHz above 2.5V.
Does AT24C16A-10TI-2.7 require external pull-up resistors on SDA and SCL lines?
Yes, AT24C16A-10TI-2.7 requires external pull-up resistors on both SDA and SCL lines because its SDA pin is open-drain and SCL is a CMOS input. Typical values range from 1.8 kΩ to 10 kΩ depending on bus capacitance and desired rise time; Microchip recommends 4.7 kΩ for standard 100 kHz operation with ≤400 pF total bus load.
How does the Write Protect (WP) pin function on AT24C16A-10TI-2.7?
On AT24C16A-10TI-2.7, the WP pin provides hardware-level write protection: when tied to VCC, it locks the entire 16K array against writes; when grounded, full read/write access is enabled. Unlike earlier AT24Cxx variants, AT24C16A applies protection to the full memory space rather than partial segments.
What package type is used for AT24C16A-10TI-2.7, and what are its key mechanical dimensions?
AT24C16A-10TI-2.7 uses an 8-lead TSSOP package (JEDEC MO-153, variation AA), with body dimensions of 3.0 mm × 4.4 mm × 1.05 mm, 0.65 mm lead pitch, and gull-wing leads. Pin 1 is marked by a corner chamfer on the bottom-left side of the package footprint.
Is AT24C16A-10TI-2.7 compatible with 1.8V I²C systems?
No, AT24C16A-10TI-2.7 is specifically rated for 2.7V to 5.5V operation. For 1.8V systems, the correct variant is AT24C16A-10TI-1.8, which guarantees 100 kHz I²C operation down to 1.8V and features different DC/AC characterization. Using AT24C16A-10TI-2.7 below 2.7V risks functional failure or undefined behavior.
