Product details
Overview
AT25080N-10SC-2.7 from Atmel (now Microchip Technology) is a 8-Kbit SPI serial EEPROM organized as 1024 × 8 bits, supporting 2.7V–5.5V operation, 32-byte page writes, and hardware/software write protection via WP pin and status register. It delivers 1 million endurance cycles and 100-year data retention for nonvolatile storage in microcontroller-based embedded systems requiring low-voltage configuration or calibration data retention.
For engineers reviewing the AT25080N-10SC-2.7 datasheet, AT25080N-10SC-2.7 pinout, AT25080N-10SC-2.7 application, or AT25080N-10SC-2.7 equivalent, this device serves as a drop-in serial memory solution compatible with SPI Mode 0 and Mode 3 interfaces, offering block-level write protection, HOLD suspend capability, and industrial-grade reliability across commercial temperature range (0°C to +70°C).
Technical Context
The AT25080N-10SC-2.7 implements a synchronous SPI slave interface with dedicated SI/SO pins, CS-driven selection, and self-timed internal write cycles (5 ms typical). Its instruction set includes WREN/WRDI for write enable/disable control and RDSR/WRSR for status and protection register access.
It supports four block write protection levels (none, 1/4, 1/2, or full array) via BP0/BP1 bits in the nonvolatile status register, and hardware write protection is enabled only when both WPEN = 1 and WP = low - allowing flexible system-level security without sacrificing field programmability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 8 Kbit (1024 words × 8 bits), sufficient for firmware parameter tables or sensor calibration coefficients in space-constrained designs. |
| Supply Voltage Range | 2.7 V to 5.5 V - enables direct interfacing with 3.3 V and 5 V microcontrollers without level-shifting. |
| Max Clock Frequency | 3.0 MHz at 5 V - supports high-throughput configuration reads and fast page writes in real-time systems. |
| Write Cycle Time | 5 ms typical - defines minimum interval between successive write commands; critical for timing-critical logging or state-save operations. |
| Endurance & Retention | 1 million write cycles / 100 years data retention - ensures long-term reliability in infrequently updated but mission-critical storage applications. |
| Operating Temperature | 0°C to +70°C - validated for commercial-grade industrial control panels, consumer electronics, and automotive body modules. |
| Package | 8-lead JEDEC SOIC (8S1), 3.9 mm × 4.9 mm footprint - compatible with standard reflow assembly and PCB layout practices. |
Pinout & Package
AT25080N-10SC-2.7 is housed in an 8-lead JEDEC SOIC package (8S1), measuring 3.9 mm × 4.9 mm with 1.27 mm lead pitch. The package supports automated pick-and-place and reflow soldering per IPC-J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select | Active-low enable signal; must be held low during entire SPI transaction to assert device on bus. |
| SCK | Serial Clock Input | Provides synchronous timing for data transfer; supports SPI Modes 0 and 3 (CPOL=0/1, CPHA=0/1). |
| SI | Serial Data Input | Receives op-codes, addresses, and write data MSB-first; ignored unless CS is low and device is write-enabled. |
| SO | Serial Data Output | Drives read data MSB-first; enters high-impedance state when CS is high or HOLD is asserted. |
| GND | Ground Reference | Primary return path for all digital I/O and supply current; requires low-impedance connection to system ground plane. |
| VCC | Power Supply | Accepts 2.7–5.5 V; decoupling capacitor (0.1 µF ceramic) required within 5 mm of pin for noise immunity. |
| WP | Write Protect Input | Hardware lock for status register writes when WPEN=1; tied high for full programmability or grounded for factory-locked protection. |
| HOLD | Communication Suspend | Pauses ongoing SPI transfer without resetting sequence; requires SCK low during assertion/deassertion. |
Key Features
| Feature | Design Value |
|---|---|
| 32-byte Page Write | Enables burst programming of up to 32 bytes per CS cycle, reducing total write time by >75% vs. byte-wise writes. |
| Four-Level Block Protection | Configurable via status register (BP1/BP0) to lock 0%, 25%, 50%, or 100% of memory - ideal for safeguarding bootloader or calibration sectors. |
| Independent Hardware/Software Protection | WP pin blocks status register writes when WPEN=1; WRDI instruction disables all writes regardless of WP state - dual-layer security. |
| HOLD Pin Functionality | Allows master MCU to pause EEPROM communication mid-transfer (e.g., during interrupt servicing), preserving address counter state. |
| Low Standby Current | 0.2 µA max at 2.7 V - extends battery life in always-on IoT sensors or portable medical devices with infrequent memory access. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| M95080-DRMN3TP/K | STMicroelectronics 8-Kbit SPI EEPROM; identical 8-lead SOIC package, 2.5–5.5 V range, but rated for -40°C to +125°C and features enhanced ESD protection (4 kV HBM). | Preferred for under-hood automotive use or harsh industrial environments where extended temperature and ESD robustness are mandatory. | Select M95080-DRMN3TP/K when operating beyond 70°C ambient or requiring higher immunity to board-level ESD events. |
| 25AA080C-I/MS | Microchip 8-Kbit SPI EEPROM; same pinout and command set, but supports 1.8–5.5 V operation and offers 10 µA standby current at 1.8 V (vs. 0.2 µA at 2.7 V for AT25080N-10SC-2.7). | Better suited for ultra-low-power battery-powered devices needing sub-2 V operation, such as wearable health monitors. | Choose 25AA080C-I/MS if system VCC can dip below 2.7 V or if lowest possible quiescent current at 1.8 V is required. |
Compared with M95080-DRMN3TP/K and 25AA080C-I/MS, the AT25080N-10SC-2.7 provides optimal balance of commercial-temperature reliability, proven 2.7–5.5 V interoperability with legacy 3.3 V MCUs, and cost-effective JEDEC SOIC packaging - making it ideal for high-volume consumer and industrial control applications where extended temp or sub-2 V operation is not required.

FAQ
What is the maximum clock frequency supported by AT25080N-10SC-2.7?
The AT25080N-10SC-2.7 supports up to 3.0 MHz SCK frequency at 5.0 V, 2.1 MHz at 2.7–5.5 V, and 0.5 MHz at 1.8–3.6 V. For the AT25080N-10SC-2.7 variant (2.7–5.5 V operation), the guaranteed maximum is 2.1 MHz per AC characteristics table - exceeding this may cause read/write failures or timing violations.
Does AT25080N-10SC-2.7 require an external pull-up resistor on the SO pin?
No, the AT25080N-10SC-2.7 drives SO actively during read operations and places it in high-impedance state otherwise; no external pull-up is needed. However, a 10 kΩ pull-up on CS is recommended to prevent spurious selection during power-up or reset sequences involving the AT25080N-10SC-2.7.
How does the HOLD function interact with the AT25080N-10SC-2.7 write cycle?
HOLD suspends serial communication but does not interrupt an active internal write cycle. Once initiated by CS high transition, the AT25080N-10SC-2.7 write completes autonomously in ~5 ms. HOLD only affects ongoing SPI transfers - not the self-timed write process already executing inside the AT25080N-10SC-2.7.
Can AT25080N-10SC-2.7 be used with SPI Mode 1 or Mode 2?
No - the AT25080N-10SC-2.7 explicitly supports only SPI Modes 0 (CPOL=0, CPHA=0) and 3 (CPOL=1, CPHA=1), as stated in its Features section. Using Mode 1 or Mode 2 will result in incorrect data sampling and failed communications with the AT25080N-10SC-2.7.
What happens if the WP pin is held low while WPEN = 0 in AT25080N-10SC-2.7?
When WPEN = 0, the WP pin is disabled and has no effect on write protection - all memory and status register writes remain fully functional even if WP is grounded. This allows safe factory programming of the AT25080N-10SC-2.7 before enabling hardware lock via WRSR instruction.
