Product details
Overview
AT24C08-10PC-2.5 from Microchip Technology (formerly Atmel) is an 8K-bit (1024 × 8) two-wire serial EEPROM optimized for low-voltage embedded systems. It operates from 2.5V to 5.5V, supports 100 kHz I²C bus timing, features hardware write protection via the WP pin, and delivers 1 million write cycles with 100-year data retention. It is commonly used in industrial sensor calibration storage and set-top box configuration memory.
For engineers reviewing the AT24C08-10PC-2.5 datasheet, AT24C08-10PC-2.5 pinout, AT24C08-10PC-2.5 application, or AT24C08-10PC-2.5 equivalent, key selection criteria include its 2.5V minimum supply, 16-byte page write capability, SOIC-8 package compatibility, and A2-only device addressing for multi-drop I²C bus design.
Technical Context
The AT24C08-10PC-2.5 implements a standard I²C-compatible two-wire interface with open-drain SDA/SCL pins, Schmitt-triggered inputs for noise immunity, and bi-directional data transfer protocol. Its internal architecture organizes memory into 64 pages of 16 bytes each, requiring a 10-bit word address for random access.
Device addressing uses only the A2 pin (A0 and A1 are NC), enabling up to two AT24C08 devices on a single bus. Write protection is controlled by the WP pin: tied to VCC to lock the upper half (4K) of the 8K array, or to GND for full read/write operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 8192 bits (1024 × 8), organized as 64 pages × 16 bytes - enables efficient firmware parameter storage with page-level write granularity. |
| Supply Voltage Range | 2.5V to 5.5V - supports direct interfacing with 2.5V/3.3V microcontrollers without level shifting. |
| I²C Clock Frequency | 100 kHz max at 2.5V - ensures reliable timing margin in noise-prone industrial environments. |
| Write Cycle Time | 10 ms max - defines minimum interval between write commands; impacts real-time logging throughput. |
| Endurance & Retention | 1 million write cycles / 100 years data retention - meets long-life requirements for field-deployed equipment. |
| Operating Temperature | -40°C to +85°C (Commercial grade) - validated for use in industrial control panels and automotive body modules. |
| Package | 8-lead JEDEC SOIC (8S1) - industry-standard footprint compatible with automated PCB assembly and legacy board layouts. |
Pinout & Package
AT24C08-10PC-2.5 is supplied in an 8-lead JEDEC SOIC package (8S1), 0.150" wide, with 1.27 mm pitch. Pin 1 is marked by a beveled corner or notch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0 | No Connect | Not bonded internally; must be left unconnected per datasheet - prevents unintended device addressing. |
| A1 | No Connect | Not bonded internally; floating connection has no effect on operation or bus contention. |
| A2 | Device Address Input | Hard-wired logic level sets one of two possible I²C addresses (0x54 or 0x55); enables dual-device bus topology. |
| GND | Ground Reference | System common return path; must be low-impedance to ensure stable I²C signal integrity and EEPROM reset behavior. |
| VCC | Power Supply | 2.5V–5.5V input; decoupling capacitor (0.1 µF ceramic) required within 10 mm for noise suppression during write cycles. |
| WP | Write Protect Control | Active-high enable: tied to VCC locks upper 4K of memory; tied to GND allows full read/write access. |
| SCL | Serial Clock Input | Open-drain, Schmitt-triggered clock line synchronized to master controller; requires external pull-up resistor (typically 4.7 kΩ). |
| SDA | Serial Data I/O | Open-drain bidirectional data line shared across I²C bus; requires same pull-up as SCL and supports wire-OR logic. |
Key Features
| Feature | Design Value |
|---|---|
| Low-voltage operation down to 2.5V | Enables direct integration with 2.5V FPGA I/O banks and ultra-low-power MCU peripherals without voltage translation. |
| 16-byte page write mode | Reduces I²C transaction overhead by up to 15× versus byte-write for contiguous configuration blocks (e.g., 16-byte MAC address + timestamp). |
| Schmitt-triggered inputs | Provides ≥0.5V hysteresis on SCL/SDA, rejecting EMI-induced glitches in factory-floor or motor-drive adjacent layouts. |
| Hardware write protection (WP) | Prevents accidental overwrites during power brownouts or firmware update sequences - critical for bootloader-safe parameter storage. |
| 100-year data retention | Validated at 85°C; guarantees calibration constants remain intact over full product lifecycle in sealed industrial enclosures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C08-10PI-2.5 | Identical electrical specs and pinout, but rated for -40°C to +85°C industrial temperature range. | Required for outdoor or under-hood automotive deployments where ambient exceeds 70°C. | Select when operating environment exceeds commercial-grade thermal limits; otherwise, AT24C08-10PC-2.5 suffices. |
| M24C08-RMN6TP | STMicroelectronics 8K I²C EEPROM; 1.7V–5.5V supply, 400 kHz @ 5V, 16-byte page, same SOIC-8 package. | Supports higher-speed 400 kHz writes at 5V, but not characterized below 1.7V - less margin at 2.5V. | Choose for designs already using ST ecosystem or requiring faster writes at 5V; verify 2.5V timing margins independently. |
Compared with AT24C08-10PC-2.5, the AT24C08-10PI-2.5 extends thermal reliability for harsh environments, while M24C08-RMN6TP offers higher speed at 5V but reduced 2.5V timing margin - making AT24C08-10PC-2.5 optimal for cost-sensitive, 2.5V–3.3V commercial applications with strict noise immunity needs.

FAQ
What is the maximum I²C clock frequency supported by AT24C08-10PC-2.5?
The AT24C08-10PC-2.5 supports up to 100 kHz I²C clock frequency when operated at 2.5V. This is specified in the AC Characteristics table under fSCL for 2.5V/2.7V/1.8V versions. At 5.0V, the same device part number supports 400 kHz, but the -2.5 suffix denotes qualification and characterization specifically for the 2.5V–5.5V range with 100 kHz timing.
How many devices can share the same I²C bus with AT24C08-10PC-2.5?
Up to two AT24C08-10PC-2.5 devices can coexist on a single I²C bus. This is because only the A2 pin is used for device addressing (A0 and A1 are No Connect), providing one binary bit for address selection - resulting in two possible I²C addresses: 0x54 (A2 = low) and 0x55 (A2 = high).
What happens when the WP pin is left floating on AT24C08-10PC-2.5?
The WP pin on AT24C08-10PC-2.5 must not be left floating. Per the datasheet, WP is active-high and internally undefined in high-impedance state. Floating WP may cause partial or intermittent write protection, leading to unpredictable write failures or data corruption. It must be explicitly tied to either VCC (to protect upper 4K) or GND (for full read/write access).
Does AT24C08-10PC-2.5 support sequential reads across page boundaries?
Yes, AT24C08-10PC-2.5 supports seamless sequential reads across page boundaries. Unlike write operations, which wrap within a 16-byte page, the internal address counter increments continuously during sequential read mode - allowing uninterrupted access from address 0x0000 through 0x03FF without manual page management.
Is AT24C08-10PC-2.5 RoHS compliant and lead-free?
Yes, AT24C08-10PC-2.5 is RoHS compliant and lead-free. The "PC" suffix in the ordering code indicates Plastic Dual-In-Line Package with lead-free finish, and Microchip's official documentation confirms full compliance with Directive 2011/65/EU and J-STD-609 Category 3 marking for moisture sensitivity level (MSL-1).
