Product details
Overview
AT25010AN-10SU-1.8 from Microchip Technology (formerly Atmel) is a 1-Kbit SPI serial EEPROM organized as 128 words × 8 bits, operating from 1.8 V to 5.5 V with 20 MHz clock support at 5 V, 8-byte page write capability, and hardware/software write protection. It serves as nonvolatile configuration storage in microcontroller-based industrial control modules requiring low-voltage operation and high data retention.
For engineers reviewing the AT25010AN-10SU-1.8 datasheet, AT25010AN-10SU-1.8 pinout, AT25010AN-10SU-1.8 application, or AT25010AN-10SU-1.8 equivalent, this device delivers verified 1.8 V–5.5 V supply compatibility, 5 ms max self-timed write cycle, 1 million endurance cycles, 100-year data retention, and SPI Mode 0/3 interoperability with host MCUs such as PIC, AVR, and ARM Cortex-M series.
Technical Context
The AT25010AN-10SU-1.8 implements a synchronous slave SPI interface with dedicated SI/SO pins, CS-controlled selection, and HOLD/ WP pins for suspend and hardware write inhibit functions. Its status register supports four block protection levels (none, 1/4, 1/2, or full array), programmable via WRSR instruction.
Internally, it uses an 8-bit instruction register with MSB-first transmission, supports continuous read with automatic address increment, and enforces write enable (WREN) before programming. All write cycles are self-timed with no external erase required, and the SO pin enters high-impedance state when deselected or during HOLD assertion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 1024 bits (128 × 8), sufficient for firmware boot flags, calibration coefficients, or device ID storage in space-constrained designs. |
| Supply Voltage Range | 1.8 V to 5.5 V - enables direct interfacing with 1.8 V logic families and backward compatibility with 3.3 V/5 V systems without level shifters. |
| Max Clock Frequency | 20 MHz at VCC = 5 V - supports high-throughput configuration loading in real-time embedded applications. |
| Write Cycle Time | 5 ms maximum - deterministic timing simplifies host MCU firmware wait-state handling and avoids polling overhead. |
| Endurance & Retention | 1 million write cycles / 100 years data retention - meets long-life requirements for industrial logging, metering, and automotive body electronics. |
| Interface Protocol | SPI Modes 0 (CPOL=0, CPHA=0) and 3 (CPOL=1, CPHA=1) - ensures interoperability with diverse microcontrollers including legacy 68HC11 and modern ARM-based SoCs. |
| Operating Temperature | −40°C to +85°C - qualified for industrial-grade operation in factory automation, HVAC controllers, and outdoor sensor nodes. |
Pinout & Package
AT25010AN-10SU-1.8 is packaged in an 8-lead JEDEC SOIC (package code 8S1), 3.9 mm × 4.9 mm body, gull-wing leads, RoHS-compliant green plastic housing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select | Active-low enable: asserts device selection; deassertion places SO in high-impedance state and halts serial communication. |
| SCK | Serial Clock | Input-only master-generated clock; defines timing for SI sampling and SO output; supports up to 20 MHz at 5 V. |
| SI | Serial Data Input | Accepts op-codes (e.g., READ, WRITE, WREN), addresses, and data; MSB-first, sampled on SCK rising edge in Mode 0. |
| SO | Serial Data Output | Tri-state output delivering memory contents; high-impedance when CS high or HOLD active; driven only during valid read sequences. |
| GND | Ground Reference | Primary return path for VCC and all I/O signals; must be low-impedance connection to minimize noise coupling into SPI lines. |
| VCC | Power Supply | Single-supply input supporting 1.8–5.5 V; internal regulation enables stable core operation across voltage range without external LDO. |
| WP | Write Protect | Hardware lock: pulling low disables all write operations regardless of status register settings or WREN state. |
| HOLD | Communication Suspend | Pauses ongoing SPI transfer without resetting sequence; requires SCK low during assertion; resumes on rising edge while SCK remains low. |
Key Features
| Feature | Design Value |
|---|---|
| 8-byte Page Write | Enables burst writes within a single 8-byte boundary, reducing total transaction time vs. byte-wise programming and minimizing host CPU intervention. |
| Block Write Protection | Four configurable protection levels (none, 1/4, 1/2, full array) via nonvolatile BP0/BP1 bits - prevents accidental overwrites of critical calibration or security data. |
| Low-Voltage Operation | Guaranteed functionality down to 1.8 V allows integration into battery-powered IoT sensors and energy-harvesting systems without voltage boosting. |
| Self-Timed Internal Write | Eliminates need for external write-cycle timing control; host initiates write and polls RDSR RDY bit (bit 0) to detect completion. |
| Industrial Temp Range | Rated for −40°C to +85°C ambient operation - suitable for deployment in uncontrolled environments like motor drives, power supplies, and building controls. |
Applications

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 8-lead SOIC package, 1.8–5.5 V, but supports 20 MHz only up to 5.5 V; lacks HOLD pin. | Higher density for multi-parameter storage; unsuitable where HOLD-based SPI pause is required for shared bus arbitration. | Select when >1 Kbit memory is needed and HOLD functionality is not used in the system architecture. |
| BR24G01FJ-3GE2 | 1 Kbit, 1.7–5.5 V, 10 MHz max clock, 8-lead TSSOP (8A2), includes built-in error correction (ECC) and write-cycle suspend. | Lower speed but enhanced reliability for safety-critical logging; different footprint requires PCB redesign. | Prefer where functional safety (IEC 61508 SIL-2) or extended write endurance under voltage droop is mandated. |
Compared with M95128-WMN6TP and BR24G01FJ-3GE2, the AT25010AN-10SU-1.8 offers optimal balance of speed (20 MHz @ 5 V), compact 8S1 footprint, HOLD/ WP dual-protection, and proven industrial qualification - making it ideal for cost-sensitive, high-volume embedded control applications where 1 Kbit suffices and bus arbitration is required.

FAQ
What is the minimum supply voltage required for reliable operation of the AT25010AN-10SU-1.8?
The AT25010AN-10SU-1.8 is rated for operation from 1.8 V to 5.5 V. At 1.8 V, it supports SPI communication up to 5 MHz (per AC Characteristics Table 4), maintains full read/write functionality, and guarantees 1 million endurance cycles. Below 1.8 V, operation is not characterized or guaranteed.
Does the AT25010AN-10SU-1.8 support SPI Mode 0 exclusively, or are other modes compatible?
The AT25010AN-10SU-1.8 supports both SPI Mode 0 (CPOL = 0, CPHA = 0) and Mode 3 (CPOL = 1, CPHA = 1), as explicitly stated in its Features section. The datasheet describes Mode 0 operation in detail, but Mode 3 is fully functional and validated for interoperability with microcontrollers requiring inverted clock polarity.
How does the HOLD pin function during an active SPI transaction on the AT25010AN-10SU-1.8?
During an active SPI transaction, asserting HOLD low (while SCK is low) suspends communication without resetting the internal address counter or command state. The SO pin enters high-impedance, and SI inputs are ignored. Resuming requires bringing HOLD high while SCK remains low - the transaction continues from the exact bit position where it paused.
Can the AT25010AN-10SU-1.8 be used in automotive applications?
The AT25010AN-10SU-1.8 is specified for industrial temperature range (−40°C to +85°C) and is not qualified to AEC-Q100 automotive standards. While it may function in some automotive cabin environments, Microchip explicitly states in its disclaimer that "Atmel's products are not intended, authorized, or warranted for use as components in applications intended to support or sustain life." Automotive use requires AEC-Q100-qualified alternatives.
What is the purpose of the Write Enable Latch (WEN) bit in the status register of the AT25010AN-10SU-1.8?
The WEN bit (bit 1 of the status register) indicates whether the device is write-enabled. It is cleared on power-up and after WRDI or successful WRITE/WRSR execution. A WREN instruction must be issued and confirmed via RDSR before any write operation - this two-step protocol prevents accidental writes due to noise or software glitches, enhancing data integrity in the AT25010AN-10SU-1.8.
