Product details
Overview
AT24C08-10TI-2.7 from Microchip Technology (formerly Atmel) is an 8K-bit (1024 × 8) I²C-compatible serial EEPROM optimized for low-voltage embedded systems. It operates from 2.7V to 5.5V, supports 400 kHz I²C bus speed at ≥2.5V, features hardware write protection via 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 AT24C08-10TI-2.7 datasheet, AT24C08-10TI-2.7 pinout, AT24C08-10TI-2.7 application, or AT24C08-10TI-2.7 equivalent, key selection criteria include I²C timing compliance at 2.7V, 16-byte page write capability, A2-only device addressing, TSSOP-8 package footprint, and automotive-grade temperature range (-40°C to +85°C).
Technical Context
The AT24C08-10TI-2.7 implements a standard two-wire I²C interface with open-drain SDA and Schmitt-triggered SCL inputs for noise immunity. Its internal architecture organizes memory into 64 pages of 16 bytes each, requiring a 10-bit word address for random access and supporting both byte and page write modes.
Device addressing uses only the A2 pin (A1 and A0 are NC), enabling up to two AT24C08 devices on a single I²C bus. Write protection is controlled solely by the WP pin: tied to VCC for upper-half array protection (4K), tied to GND for full read/write operation - no software lock required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 8192 bits (1024 × 8), organized as 64 pages × 16 bytes - enables efficient parameter storage without external address latches. |
| Supply Voltage Range | 2.7V to 5.5V - compatible with 3.3V and 5V microcontroller I/O domains without level shifting. |
| I²C Clock Frequency | 400 kHz (at VCC ≥ 2.5V); 100 kHz (at VCC = 1.8V) - ensures fast configuration writes in 3.3V systems while maintaining robustness at lower voltages. |
| Page Write Capacity | 16-byte page writes - reduces I²C transaction count for bulk updates (e.g., logging 16 sensor readings per burst). |
| Write Endurance | 1,000,000 write cycles - supports frequent recalibration or runtime parameter adjustment in industrial controllers. |
| Data Retention | 100 years at +25°C - guarantees long-term validity of stored calibration coefficients or security keys across product lifetime. |
| Operating Temperature | -40°C to +85°C - qualified for industrial and automotive under-hood applications where thermal stability is critical. |
Pinout & Package
AT24C08-10TI-2.7 is supplied in an 8-lead Thin Shrink Small Outline Package (TSSOP), 0.170" wide body, with 0.65 mm lead pitch. Pin 1 is marked by a notch or dot; package meets JEDEC MO-153, Variation AA.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0 | No Connect | Not bonded internally; must be left unconnected - eliminates ambiguity in device addressing logic. |
| A1 | No Connect | Not bonded internally; must be left unconnected - ensures deterministic A2-only addressing behavior. |
| A2 | Device Address Input | Hard-wired input determining LSB of 7-bit I²C slave address (0x50 or 0x51); enables dual-device bus topology. |
| GND | Ground Reference | Return path for all internal circuitry and I²C pull-up currents; requires low-impedance connection to system ground plane. |
| VCC | Power Supply | Primary supply for EEPROM core and I²C interface; decoupling capacitor (0.1 µF) recommended within 10 mm. |
| WP | Write Protect Control | Active-high hardware lock: VCC = upper-half (4K) protection; GND = full read/write - no firmware overhead needed. |
| SCL | I²C Clock Input | Positive-edge clock for data sampling; Schmitt-trigger input rejects noise spikes up to 50 ns duration. |
| SDA | I²C Bidirectional Data | Open-drain output with 8 pF max capacitance; requires external pull-up (typically 2.2–10 kΩ) to VCC. |
Key Features
| Feature | Design Value |
|---|---|
| 16-byte page write mode | Reduces I²C bus occupancy by 87% vs. eight separate byte writes - critical for real-time systems with tight timing budgets. |
| Schmitt-trigger SCL input | Enables reliable operation in electrically noisy environments (e.g., motor drives) with >100 ns noise suppression window. |
| Self-timed write cycle | Fixed 5 ms max internal erase/program time - simplifies host firmware by eliminating polling or timeout tuning. |
| Hardware write protection (WP) | Prevents accidental overwrites during power transients or firmware faults - no software vulnerability surface. |
| 100-year data retention | Validates long-term integrity of stored cryptographic keys or calibration offsets without periodic refresh routines. |

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-2.7 | Successor part with enhanced ESD rating (4 kV HBM), same pinout, identical timing and memory map. | Preferred for new designs per Microchip documentation; identical functional behavior in existing circuits. | Select AT24C08A-10TI-2.7 for new designs requiring extended reliability; AT24C08-10TI-2.7 remains valid for legacy repair or continuity. |
| 24LC08BT-I/OT | Microchip 8K I²C EEPROM in SOT-23-5 package; 1.8–5.5V operation; 400 kHz @ 2.5V+; A0/A1/A2 pins fully implemented. | Smaller footprint but different pinout (5-pin vs. 8-pin) and 3-address-bit addressing - requires PCB redesign. | Choose 24LC08BT-I/OT only when board space is constrained and layout revision is acceptable. |
Compared with AT24C08A-10TI-2.7, the AT24C08-10TI-2.7 lacks updated ESD hardening but maintains full electrical and functional equivalence; versus 24LC08BT-I/OT, it offers TSSOP-8 compatibility and simplified A2-only addressing but occupies more PCB area.

FAQ
What is the maximum I²C clock frequency supported by AT24C08-10TI-2.7?
The AT24C08-10TI-2.7 supports up to 400 kHz I²C clock frequency when VCC is 2.5V or higher, and 100 kHz when operating at 1.8V. At its rated 2.7V–5.5V range, the 400 kHz mode is fully guaranteed per AC characteristics table - enabling faster configuration writes than legacy 100 kHz EEPROMs without compromising signal integrity.
Does AT24C08-10TI-2.7 require external pull-up resistors on SDA and SCL lines?
Yes, AT24C08-10TI-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 for 3.3V systems with ≤400 pF total bus capacitance.
How does the Write Protect (WP) pin function on AT24C08-10TI-2.7?
On AT24C08-10TI-2.7, the WP pin provides hardware-level write protection: when tied to VCC, it locks the upper half (4K) of memory (addresses 0x200–0x3FF); when tied to GND, full read/write access is enabled. This behavior is fixed and requires no software configuration - protecting critical data against accidental overwrite during firmware execution.
What package type is used for AT24C08-10TI-2.7?
AT24C08-10TI-2.7 uses an 8-lead Thin Shrink Small Outline Package (TSSOP), designated as 8A2 in Microchip's ordering nomenclature. It measures 3.00 mm × 4.40 mm with 0.65 mm lead pitch and complies with JEDEC MO-153, Variation AA - offering compact size and gull-wing leads suitable for automated assembly.
Is AT24C08-10TI-2.7 suitable for automotive applications?
Yes, AT24C08-10TI-2.7 is qualified for industrial temperature range (-40°C to +85°C) and specified for automotive-grade reliability, including 1 million write cycles and 100-year data retention. While not AEC-Q100 certified, its extended temperature rating and robust construction make it suitable for non-safety-critical automotive subsystems like body control modules and infotainment configuration storage.
