Product details
Overview
AT25080AN-10SU-2.7-T from Microchip Technology (formerly Atmel) is an 8-Kbit SPI serial EEPROM organized as 1024 × 8 bits, supporting 2.7–5.5 V operation, 20 MHz clock rate at 5 V, 32-byte page write, and hardware/software write protection via WP pin and status register. It serves as nonvolatile configuration storage in industrial control modules, power supply supervisors, and embedded sensor nodes.
For engineers reviewing the AT25080AN-10SU-2.7-T datasheet, AT25080AN-10SU-2.7-T pinout, AT25080AN-10SU-2.7-T application, or AT25080AN-10SU-2.7-T equivalent, key selection criteria include SPI Mode 0/3 compatibility, 1 million write cycles endurance, 100-year data retention, block-level write protection (1/4, 1/2, or full array), and JEDEC SOIC-8 packaging with RoHS-compliant green finish.
Technical Context
The AT25080AN-10SU-2.7-T operates as a slave device on a three-wire SPI bus (CS, SCK, SI/SO), requiring WREN instruction before any write and supporting MSB-first transmission. Its internal architecture includes an 8-bit instruction register and nonvolatile status register with BP0/BP1 for memory segmentation and WPEN for hardware write protect enable/disable.
Timing is governed by strict AC parameters: tWH/tWL ≤ 20 ns (5 V), tSU/tH ≥ 5 ns (1.8 V), and tWC = 5 ms max self-timed write cycle. HOLD pin suspends communication without resetting the sequence, while WP pin blocks status register writes when WPEN = 1 and WP = low - enabling robust field-programmable protection.
Key Specifications

AT25080AN-10SU-2.7-T is supplied in an 8-lead JEDEC SOIC package (8S1), 0.150" wide body, RoHS-compliant green finish (U suffix), with standard gull-wing lead form and 1.27 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select | Active-low enable; must be low to accept instructions; high impedance SO when CS high |
| SCK | Serial Clock | Input only; defines timing for SI/SO data transfer; supports up to 20 MHz at 5 V |
| SI | Serial Data Input | Receives op-codes, addresses, and data; MSB-first protocol; ignored during HOLD or write cycle |
| SO | Serial Data Output | Tri-state output; drives data during READ; high-Z when CS high or during internal write |
| GND | Ground Reference | Signal and power return path; must be low-impedance for stable SPI signaling |
| VCC | Power Supply | 2.7–5.5 V input; powers internal logic and charge pump; decoupling capacitor required |
| WP | Write Protect | Hardware lock for status register; active low only when WPEN = 1; prevents accidental BP/WPEN changes |
| HOLD | Communication Suspend | Pauses ongoing SPI transfer without resetting address counter; requires SCK low to assert |
Key Features
| Feature | Design Value |
|---|---|
| Block Write Protection | Configurable via status register to protect 0%, 25%, 50%, or 100% of memory - enables secure boot code partitioning |
| Hardware + Software Write Protection | WP pin (hardware) and WRSR/WREN instructions (software) provide layered data integrity - critical for field-upgradable systems |
| Self-timed Write Cycle | No external erase step required; 5 ms max duration; RDSR polling confirms completion - simplifies host firmware design |
| Low-Voltage Operation | Functional down to 2.7 V - supports brown-out tolerant operation in battery-backed or energy-harvesting applications |
| HOLD Pin Functionality | Enables multi-master arbitration or CPU interrupt handling without losing SPI context - preserves sequential read/write continuity |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| M95080-DRMN6TP/K | STMicroelectronics 8-Kbit SPI EEPROM; identical 8-lead SOIC-8 package; supports 1.8–5.5 V but rated for 10 MHz max at 1.8 V vs. AT25080AN-10SU-2.7-T's 20 MHz at 5 V | Limited to lower-speed interfaces; lacks HOLD pin - unsuitable for multi-master or interrupt-driven hosts | Select when cost sensitivity outweighs speed/HOLD requirements and ST ecosystem alignment is preferred |
| BR24G08NUX-10 | Rohm 8-Kbit SPI EEPROM; 8-lead TSSOP-8 (4.4 mm body); supports 1.7–5.5 V; 10 MHz max clock; no HOLD pin; write protection limited to software-only | Smaller footprint than SOIC but no hardware suspend capability; lower endurance (400k cycles) | Choose for compact PCB layouts where HOLD is unused and moderate write frequency suffices |
Compared with M95080-DRMN6TP/K and BR24G08NUX-10, the AT25080AN-10SU-2.7-T delivers higher SPI throughput, integrated HOLD functionality for deterministic host control, and superior endurance - making it optimal for industrial and medical applications demanding reliability and real-time responsiveness.

FAQ
What is the maximum SPI clock frequency supported by the AT25080AN-10SU-2.7-T?
The AT25080AN-10SU-2.7-T supports up to 20 MHz SCK frequency when operated at VCC = 5.0 V. At 2.7 V, the maximum clock rate is 10 MHz, and at 1.8 V it drops to 5 MHz - all specified in the AC Characteristics table. This graded performance allows designers to optimize speed versus power consumption based on system voltage rails.
Does the AT25080AN-10SU-2.7-T require an external erase command before writing?
No, the AT25080AN-10SU-2.7-T does not require a separate erase command. All write operations - including byte and 32-byte page writes - are self-timed and automatically erase the target location prior to programming. The internal write cycle completes in ≤5 ms, and readiness is confirmed via the RDY bit in the status register using RDSR.
How is write protection implemented on the AT25080AN-10SU-2.7-T?
The AT25080AN-10SU-2.7-T implements dual-layer write protection: hardware-based via the WP pin (active low when WPEN = 1) and software-based via status register bits BP0/BP1. These bits configure protection for 0%, 25%, 50%, or 100% of the memory array. WP blocks status register writes; BP bits define protected address ranges - enabling granular, field-updatable security policies.
What package type is used for the AT25080AN-10SU-2.7-T?
The AT25080AN-10SU-2.7-T uses an 8-lead JEDEC SOIC package (8S1), 0.150" wide body, with gull-wing leads, 1.27 mm pitch, and RoHS-compliant green finish (U suffix). It is pin-compatible with industry-standard SOIC-8 footprints and supports reflow soldering per J-STD-020.
Can the AT25080AN-10SU-2.7-T operate reliably at -40°C?
Yes, the AT25080AN-10SU-2.7-T is rated for industrial temperature range (-40°C to +85°C) per its ordering code suffix and DC/AC specifications. All parameters - including ICC, ISB, tWC, and VIL/VIH - are guaranteed across this range, and the device undergoes 100% testing at temperature extremes during manufacturing.
