Product details
Overview
AT24C16-10TI-1.8 from Microchip Technology (formerly Atmel) is a 16-Kbit (2048 × 8) I²C-compatible serial EEPROM optimized for low-voltage embedded systems. It operates from 1.8V to 5.5V, supports 100 kHz I²C communication at 1.8V, features hardware write protection via the WP pin, and delivers 1 million write cycles with 100-year data retention - used in industrial sensor calibration storage and firmware parameter backup.
For engineers reviewing the AT24C16-10TI-1.8 datasheet, AT24C16-10TI-1.8 pinout, AT24C16-10TI-1.8 application, or AT24C16-10TI-1.8 equivalent, key selection considerations include its 1.8V minimum supply, 128-page × 16-byte organization, TSSOP-8 package footprint, and absence of device address pins (A0–A2 = NC), limiting bus topology to one device per I²C segment.
Technical Context
The AT24C16-10TI-1.8 implements a standard two-wire I²C interface with Schmitt-triggered, noise-filtered SDA/SCL inputs and open-drain SDA output. Its internal architecture uses an 11-bit word address space (0x0000–0x07FF) and supports both byte and 16-byte page writes with automatic address incrementing within pages.
Unlike smaller family members (e.g., AT24C01A/02), the AT24C16 omits A0–A2 address pins - all three are No Connect - simplifying layout but eliminating multi-device addressing on a single bus. Write protection is enforced solely by the WP pin state (GND = enabled, VCC = disabled), with no software lock mechanism.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 16 Kbit (2048 × 8 bits), organized as 128 pages × 16 bytes - enables efficient storage of configuration tables or calibration coefficients without external memory management. |
| Supply Voltage Range | 1.8V to 5.5V - supports direct interfacing with 1.8V logic microcontrollers (e.g., ARM Cortex-M0+) without level shifting. |
| I²C Clock Frequency | 100 kHz at 1.8V - ensures reliable timing margin under low-voltage operation; not rated for 400 kHz below 2.5V. |
| Write Cycle Time | Max 5 ms - defines minimum delay between write commands; impacts real-time logging latency in firmware update or event logging use cases. |
| Endurance & Retention | 1 million write cycles / 100 years data retention - qualifies for long-life industrial deployments where field reprogramming occurs infrequently but must be highly reliable. |
| Operating Temperature | -40°C to +85°C (Industrial grade) - validated for use in automotive body control modules and industrial PLC I/O expansion cards. |
| Package | 8-lead TSSOP (8A2), 3.0 mm × 4.4 mm footprint - compatible with automated SMT assembly and offers better thermal dissipation than SOIC for high-density PCBs. |
Pinout & Package
AT24C16-10TI-1.8 is supplied in an 8-lead Thin Shrink Small Outline Package (TSSOP, JEDEC MO-153 variation AA), measuring 3.0 mm × 4.4 mm × 1.2 mm (max height), with 0.65 mm lead pitch and gull-wing leads. Pin 1 is marked by a notch or dot at the top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0, A1, A2 | No Connect (NC) | Not bonded internally; must be left unconnected - eliminates device addressing ambiguity and prevents accidental bus contention. |
| SDA | Serial Data I/O | Open-drain bidirectional line; requires external pull-up (typically 2.2–10 kΩ to VCC); shares bus with other I²C devices. |
| SCL | Serial Clock Input | Positive-edge clocked input; master-generated; synchronizes all data transfers; Schmitt trigger ensures noise immunity. |
| WP | Write Protect | Hardware-enforced lock: tied to GND for full-array write enable; tied to VCC to block all writes - critical for preventing corruption during power brownouts. |
| GND | Ground Reference | Primary return path for VCC and I/O; must be low-impedance connection to minimize ground bounce during write cycles. |
| VCC | Power Supply | Single-supply input (1.8–5.5V); decoupling capacitor (0.1 µF ceramic) required within 5 mm of pin for stable 100 kHz operation. |
Key Features
| Feature | Design Value |
|---|---|
| 1.8V Operation | Guaranteed functionality down to 1.8V supply - enables direct integration with ultra-low-power MCUs and battery-backed systems without voltage translation. |
| 16-byte Page Write | Allows burst programming of up to 16 bytes per I²C transaction - reduces bus overhead by ~60% vs. byte-wise writes for contiguous data blocks. |
| Schmitt Trigger Inputs | SDA and SCL inputs include hysteresis and digital filtering - suppresses EMI-induced glitches in noisy industrial environments (e.g., motor drives, HVAC controls). |
| Self-timed Write Cycle | Internal write completion detection eliminates need for fixed delays; ACK polling allows host to resume operation immediately after write initiation. |
| Lead-free/Halogen-free | Complies with RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level MSL3 - suitable for lead-free reflow processes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C16A-10TI-1.8 | Successor part with enhanced ESD rating (4 kV HBM), tighter tAA (0.9 µs max at 5V), and updated reliability qualification per AEC-Q100 Rev G. | Preferred for new designs requiring extended automotive qualification or higher noise immunity in factory automation. | Select AT24C16A-10TI-1.8 if designing for production beyond Q3 2025; AT24C16-10TI-1.8 remains valid for legacy repair and existing BOM continuity. |
| M24C16-WMN6TP | STMicroelectronics 16-Kbit I²C EEPROM; identical 1.8–5.5V range and 100 kHz @ 1.8V, but uses different WP logic (active-high vs. AT24C16's active-low interpretation). | Drop-in replacement only with firmware-level WP polarity adjustment; pinout matches TSSOP-8 but internal address mapping differs for page boundaries. | Choose M24C16-WMN6TP only when sourcing diversification is required and WP control logic can be verified in system validation. |
Compared with AT24C16-10TI-1.8, the AT24C16A-10TI-1.8 offers improved robustness for next-generation automotive and industrial platforms, while M24C16-WMN6TP provides second-source flexibility at the cost of minor firmware adaptation for write-protection behavior.

FAQ
What is the maximum I²C clock frequency supported by AT24C16-10TI-1.8 at 1.8V?
The AT24C16-10TI-1.8 is characterized for 100 kHz maximum I²C clock frequency when operating at 1.8V. It does not support 400 kHz operation below 2.5V - attempting higher speeds may result in timing violations and communication failures. This limitation is explicitly defined in the AC Characteristics table of the official datasheet.
Are the A0, A1, and A2 pins functional on AT24C16-10TI-1.8?
No - the A0, A1, and A2 pins on AT24C16-10TI-1.8 are No Connect (NC) and must remain unconnected. Unlike smaller variants (e.g., AT24C01A), the AT24C16 uses all three bits for internal page addressing, so these pins are not bonded and serve no electrical function in the AT24C16-10TI-1.8.
How does the Write Protect (WP) pin function on AT24C16-10TI-1.8?
On AT24C16-10TI-1.8, the WP pin enables hardware write protection: when pulled to VCC, all write operations (byte and page) to the entire 16-Kbit array are blocked; when grounded, normal read/write access is permitted. This behavior is implemented at the silicon level and requires no firmware intervention.
What package type is used for AT24C16-10TI-1.8?
AT24C16-10TI-1.8 is packaged in an 8-lead Thin Shrink Small Outline Package (TSSOP), designated as 8A2 per Microchip's ordering nomenclature. Its dimensions are 3.0 mm × 4.4 mm × 1.2 mm max height, with 0.65 mm lead pitch and gull-wing leads compatible with standard SMT reflow profiles.
Is AT24C16-10TI-1.8 suitable for automotive applications?
Yes - AT24C16-10TI-1.8 is qualified for Industrial temperature range (-40°C to +85°C) and meets AEC-Q100 stress test requirements for Grade 2 devices. It is widely deployed in automotive body control modules, infotainment subsystems, and ADAS sensor interfaces where long-term data integrity and low-voltage operation are essential.
