Product details
Overview
AT25010AN-10SU-2.7 from Microchip Technology (formerly Atmel) is a 1-Kbit SPI serial EEPROM organized as 128 words × 8 bits, operating from 2.7V to 5.5V with 20 MHz max clock rate at 5V, 8-byte page write capability, and hardware/software write protection. It serves as nonvolatile configuration storage in microcontroller-based industrial control modules requiring low-power, space-constrained, and reliable data retention.
For engineers reviewing the AT25010AN-10SU-2.7 datasheet, AT25010AN-10SU-2.7 pinout, AT25010AN-10SU-2.7 application, or AT25010AN-10SU-2.7 equivalent, key selection criteria include VCC range compatibility (2.7–5.5 V), SPI Mode 0/3 support, 100-year data retention, 1 million write cycles, and TSSOP-8 package footprint for PCB layout verification.
Technical Context
The AT25010AN-10SU-2.7 implements a synchronous serial peripheral interface (SPI) slave architecture with dedicated SI/SO lines, CS-controlled selection, and HOLD/ WP pins for real-time communication suspension and hardware-level write inhibition. Its internal status register enables programmable block protection (1/4, 1/2, or full array) via WRSR instruction.
It uses self-timed internal write cycles (≤5 ms), requires explicit WREN before WRITE, and supports MSB-first data transfer with op-code–driven command execution (READ, WRITE, RDSR, WRSR). The device powers up in write-disabled state and maintains high-impedance SO during CS high or HOLD active.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 1024 bits (128 × 8), sufficient for firmware revision IDs, calibration coefficients, or small parameter sets in embedded systems. |
| Supply Voltage Range | 2.7 V to 5.5 V - compatible with both 3.3 V and 5 V logic domains without level shifting. |
| Max Clock Frequency | 20 MHz at VCC = 5 V - enables fast configuration reads during boot or runtime updates. |
| Write Endurance | 1 million cycles - supports frequent logging or counter updates in telemetry or metering applications. |
| Data Retention | 100 years at +25 °C - ensures long-term reliability for unattended equipment like remote sensors or infrastructure controllers. |
| Page Write Size | 8 bytes - minimizes write latency per transaction while avoiding overwriting adjacent data in partial updates. |
| Operating Temperature | −40 °C to +85 °C - qualified for industrial environments including factory automation and outdoor electronics. |
Pinout & Package
AT25010AN-10SU-2.7 is packaged in an 8-lead JEDEC SOIC (8S1), 3.9 mm × 4.9 mm body, gull-wing lead form, RoHS-compliant and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select | Active-low enable signal; must be low to accept commands; high places SO in high-impedance state. |
| SCK | Serial Clock | Input-only clock synchronized to master; defines timing for SI sampling and SO output edges. |
| SI | Serial Data Input | Command/address/data input path; MSB-first; ignored when CS is high or HOLD is active. |
| SO | Serial Data Output | Read data output; tri-stated when CS high or during HOLD; valid after tV delay from SCK edge. |
| WP | Write Protect | Hardware lock: low disables all write operations regardless of WREN status or status register settings. |
| HOLD | Communication Suspend | Pauses ongoing SPI transfer without resetting sequence; requires SCK low during assertion/deassertion. |
| VCC | Power Supply | Primary supply rail (2.7–5.5 V); powers internal logic, memory array, and I/O buffers. |
| GND | Ground Reference | Return path for VCC and all I/O signals; must be low-impedance to ensure noise immunity and timing integrity. |
Key Features
| Feature | Design Value |
|---|---|
| SPI Mode 0 & 3 Support | Interoperates with diverse MCU families (e.g., 68HC11, ARM Cortex-M) without protocol translation logic. |
| Block Write Protection | Configurable via status register to protect 0%, 25%, 50%, or 100% of memory - prevents accidental overwrite of critical firmware parameters. |
| Self-timed Write Cycle | No external erase step required; ≤5 ms internal programming eliminates need for timeout polling in host firmware. |
| Low Standby Current | 0.2 µA typical at 2.7 V - extends battery life in portable or energy-harvesting sensor nodes. |
| HOLD Pin Functionality | Enables multi-master arbitration or CPU interrupt handling without losing SPI context - avoids reinitialization overhead. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| M95128-WMN6TP | 128 Kbit capacity, same SOIC-8 package, 5 MHz max clock at 2.7 V, no HOLD pin. | Larger memory but slower interface; lacks HOLD for suspended transfers - unsuitable where multi-tasking SPI arbitration is required. | Select when higher density is needed and HOLD functionality is unused; verify timing margins for 2.7 V operation. |
| 25AA010A-I/SN | Same 1 Kbit size, SOIC-8, 10 MHz max clock at 2.7 V, identical WP/HOLD pin functions and status register layout. | Drop-in replacement with identical pinout, timing, and instruction set - validated for interoperability in existing AT25010A designs. | Preferred for new designs seeking second-source assurance; shares same Microchip manufacturing and qualification baseline. |
Compared with M95128-WMN6TP and 25AA010A-I/SN, the AT25010AN-10SU-2.7 offers optimal balance of speed (20 MHz @5 V), proven industrial reliability, and HOLD-enabled SPI flexibility - making it ideal for real-time embedded systems where deterministic communication pause/resume is essential.

FAQ
What is the maximum clock frequency supported by the AT25010AN-10SU-2.7?
The AT25010AN-10SU-2.7 supports up to 20 MHz SCK frequency at VCC = 5.0 V, 10 MHz at 2.7–3.6 V, and 5 MHz at 1.8–2.7 V. These values are specified in Table 4 of the datasheet and reflect guaranteed AC timing performance across temperature and voltage ranges. The AT25010AN-10SU-2.7 must operate within these limits to ensure reliable read/write command execution and data validity.
Does the AT25010AN-10SU-2.7 require an external erase cycle before writing?
No, the AT25010AN-10SU-2.7 performs self-timed internal erase-and-write operations automatically. Each WRITE instruction triggers a complete internal cycle (≤5 ms), eliminating the need for separate erase commands or host-managed sector erasure. This simplifies firmware design and reduces write latency compared to parallel EEPROMs - a core feature confirmed in the Functional Description section of the AT25010AN-10SU-2.7 datasheet.
How does the WP pin function on the AT25010AN-10SU-2.7?
The WP (Write Protect) pin on the AT25010AN-10SU-2.7 provides hardware-level write inhibition: when held low, it blocks all write operations-including WREN, WRITE, and WRSR-regardless of status register settings or software enable state. This hardwired protection complements software-based BP bits and is critical for safeguarding factory-programmed data. The AT25010AN-10SU-2.7 datasheet explicitly states that WP low overrides all other write controls.
Can the AT25010AN-10SU-2.7 be used in SPI Mode 3 (CPOL=1, CPHA=1)?
Yes, the AT25010AN-10SU-2.7 explicitly supports both SPI Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1), as stated in the Features section. Its bidirectional SO line and edge-triggered sampling are designed for compatibility with either polarity/phase configuration. However, the datasheet describes timing and operation only for Mode 0 - users implementing Mode 3 must validate setup/hold timing against AC specifications under inverted clock conditions.
What package type is used for the AT25010AN-10SU-2.7?
The AT25010AN-10SU-2.7 uses an 8-lead JEDEC SOIC package (ordering code suffix "SU", package code 8S1), measuring 3.9 mm × 4.9 mm with gull-wing leads. This is confirmed in the AT25010A Ordering Information table and Packaging Information drawing 8S1. The "U" suffix denotes RoHS-compliant, halogen-free construction - a verified physical and environmental attribute of the AT25010AN-10SU-2.7.
