Product details
Overview
AT24C08-10TI-1.8 from Microchip Technology (formerly Atmel) is an 8K-bit (1024 × 8) I²C-compatible serial EEPROM optimized for low-voltage embedded systems. It operates from 1.8V to 5.5V, supports 100 kHz I²C clocking 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 power-management configuration memory.
For engineers reviewing the AT24C08-10TI-1.8 datasheet, AT24C08-10TI-1.8 pinout, AT24C08-10TI-1.8 application, or AT24C08-10TI-1.8 equivalent, key selection criteria include 1.8V minimum supply compatibility, 16-byte page write capability, TSSOP-8 package footprint, Schmitt-trigger noise immunity on SDA/SCL, and automotive-grade temperature range (-40°C to +85°C).
Technical Context
The AT24C08-10TI-1.8 implements a standard two-wire I²C interface with open-drain SDA and active-high SCL, supporting standard-mode (100 kHz) operation at 1.8V supply. Its internal architecture organizes 8192 bits into 64 pages of 16 bytes each, with automatic address incrementing during page writes and wraparound behavior at page boundaries.
Device addressing uses only the A2 pin (A0 and A1 are NC), enabling up to two AT24C08 devices on a single I²C bus. The WP pin provides hardware-level write protection: tied to VCC disables all writes to the full array, while grounded enables normal read/write operations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 8 Kbit (1024 × 8 bits), organized as 64 pages × 16 bytes - supports compact firmware parameter storage without external address latches. |
| Supply Voltage Range | 1.8V to 5.5V - enables direct interfacing with 1.8V logic families and mixed-voltage systems without level shifters. |
| I²C Clock Frequency | 100 kHz max at 1.8V - ensures reliable timing margin in low-power microcontroller applications with limited drive strength. |
| Page Write Capacity | 16-byte page writes - reduces I²C transaction overhead by up to 15× vs. byte-wise writes for burst configuration updates. |
| Endurance & Retention | 1 million write cycles / 100 years data retention - suitable for field-updatable calibration tables in industrial equipment. |
| Operating Temperature | -40°C to +85°C - qualified for use in automotive body control modules and industrial PLC I/O expansion cards. |
| Write Protect Function | Hardware-enabled via WP pin - prevents accidental overwrites during power transitions or firmware glitches without software intervention. |
Pinout & Package
AT24C08-10TI-1.8 is supplied in an 8-lead Thin Shrink Small Outline Package (TSSOP), 4.4 mm body width, JEDEC MO-153 compliant, with 0.65 mm lead pitch. Pin 1 is marked by a notch or dot; device orientation follows standard JEDEC top-view labeling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0 | No-connect (NC) | Not bonded internally; must be left unconnected - omission avoids unintended device addressing conflicts. |
| A1 | No-connect (NC) | Not bonded internally; floating or tied to any potential has no effect on operation or addressing. |
| A2 | Device Address Input | Hardwired input determining LSB of 7-bit I²C slave address; enables dual-device bus configuration (0 or 1). |
| GND | Ground Reference | Return path for VCC and signal currents; requires low-impedance connection to system ground plane. |
| VCC | Power Supply | 1.8–5.5V main supply; decoupling capacitor (0.1 µF ceramic) required within 5 mm of pin for noise immunity. |
| WP | Write Protect Control | Active-high enable: VCC = full-array write lock; GND = normal read/write - used for factory programming lockout. |
| SCL | Serial Clock Input | Positive-edge sampled clock; requires external pull-up; max 100 kHz at 1.8V - defines I²C transaction timing. |
| SDA | Serial Data I/O | Open-drain bidirectional bus line; requires external pull-up; Schmitt-trigger inputs suppress EMI-induced glitches. |
Key Features
| Feature | Design Value |
|---|---|
| 1.8V-compatible I²C interface | Guaranteed 100 kHz operation down to 1.8V supply - eliminates need for voltage translators in ultra-low-power designs. |
| 16-byte page write mode | Reduces I²C bus occupancy by minimizing START/STOP overhead - accelerates bulk parameter saves in real-time systems. |
| Schmitt-trigger inputs on SDA/SCL | Suppresses noise-induced false clock/data transitions in electrically noisy environments like motor drives or power supplies. |
| Hardware write protection (WP) | Prevents corruption during brown-out, reset, or firmware faults - critical for preserving calibration or security keys. |
| Automotive-grade qualification | Rated for -40°C to +85°C operation with lead-free/halogen-free packaging - meets AEC-Q200 stress test requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C08A-10TI-1.8 | Successor with enhanced ESD robustness (4 kV HBM), same pinout and electrical specs; recommended for new designs per Microchip documentation. | Identical use cases but preferred for production ramp due to extended lifecycle support and improved manufacturing yield. | Select AT24C08A-10TI-1.8 for new designs requiring long-term availability and higher reliability margins. |
| M24C08-RMN6TP | STMicroelectronics 8K I²C EEPROM; 1.7–5.5V range, 400 kHz @ 2.5V+, 16-byte page write, SO8/TSSOP8 compatible. | Same footprint and protocol but lacks 100 kHz guarantee at 1.8V - requires validation if operating below 2.5V. | Choose M24C08-RMN6TP only if system operates ≥2.5V and ST's qualification profile better matches your supply chain needs. |
Compared with AT24C08-10TI-1.8, the AT24C08A-10TI-1.8 offers identical functionality with documented longevity improvements, while M24C08-RMN6TP provides second-source flexibility but requires voltage-margin verification for 1.8V operation.

FAQ
What is the maximum I²C clock frequency supported by AT24C08-10TI-1.8 at 1.8V?
The AT24C08-10TI-1.8 supports a maximum I²C clock frequency of 100 kHz when operated at 1.8V supply. This is explicitly characterized and guaranteed in the AC Electrical Characteristics table of the official datasheet. Higher frequencies (e.g., 400 kHz) require VCC ≥ 2.5V and are not valid for AT24C08-10TI-1.8 at 1.8V operation.
Does AT24C08-10TI-1.8 support partial page writes?
Yes, AT24C08-10TI-1.8 supports partial page writes: up to 16 bytes can be written in a single transaction, starting at any byte offset within a 16-byte page boundary. If more than 16 bytes are sent, the address wraps to the start of the same page, overwriting prior data - a behavior confirmed in the "Page Write" section of the datasheet.
What is the function of pins A0 and A1 on AT24C08-10TI-1.8?
On AT24C08-10TI-1.8, both A0 and A1 are designated as No Connect (NC) pins - they are not bonded internally and have no functional role. Only A2 serves as the device address bit, allowing two AT24C08 devices on one I²C bus. Leaving A0/A1 unconnected avoids addressing ambiguity.
How does the WP pin protect memory on AT24C08-10TI-1.8?
When the WP pin of AT24C08-10TI-1.8 is driven high (tied to VCC), all write operations - including byte, page, and sequential writes - are disabled across the entire 8K-bit array. When WP is grounded, normal read and write functions operate. This hardware lock operates independently of I²C commands and persists through power cycles.
Is AT24C08-10TI-1.8 suitable for automotive applications?
Yes, AT24C08-10TI-1.8 is qualified for automotive-grade use with an operating temperature range of -40°C to +85°C and lead-free/halogen-free packaging. It meets industrial and extended-temperature requirements referenced in the "Automotive Grade" feature list and ordering information - though formal AEC-Q200 certification status should be verified per lot documentation.
