Product details
Overview
AT25010AN-10SI-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-voltage operation and automotive-grade reliability.
For engineers reviewing the AT25010AN-10SI-2.7 datasheet, AT25010AN-10SI-2.7 pinout, AT25010AN-10SI-2.7 application, or AT25010AN-10SI-2.7 equivalent, key selection criteria include VCC range (2.7–5.5V), SPI Mode 0/3 compatibility, 1M write endurance, 100-year data retention, and TSSOP-8 packaging for space-constrained PCBs.
Technical Context
The AT25010AN-10SI-2.7 implements a synchronous serial peripheral interface (SPI) slave architecture with separate SI/SO pins, MSB-first data transfer, and chip-select–driven command sequencing. Its internal status register controls block write protection (BP1/BP0) and write-enable state (WEN), enabling selective 1/4-, 1/2-, or full-array locking.
All operations-including READ, WRITE, WREN, WRDI, RDSR, and WRSR-are initiated by CS falling edge followed by op-code transmission. The device supports HOLD pin suspension of ongoing transfers without sequence reset and self-timed internal write cycles completing in ≤5 ms, eliminating external erase steps.
Key Specifications

| Memory Size | 1024 bits (128 × 8-bit words) - sufficient for firmware boot flags, calibration coefficients, or device ID storage |
| Interface | SPI slave with Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1) support - interoperable with diverse MCU SPI peripherals |
| Supply Voltage | 2.7V to 5.5V - enables direct integration into 3.3V and 5V systems without level-shifting |
| Max Clock Rate | 20 MHz at VCC = 5V - supports high-throughput configuration loading in time-critical applications |
| Write Endurance | 1 million cycles - ensures long-term reliability in field-updatable embedded devices |

Pinout & Package
AT25010AN-10SI-2.7 is packaged in an 8-lead JEDEC SOIC (8S1), 0.150" wide, gull-wing surface-mount package measuring 5.00 mm × 3.99 mm × 1.75 mm (L × W × H), compatible with standard reflow profiles and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select | Active-low enable signal; initiates all serial commands and places SO in high-impedance when deasserted |
| SCK | Serial Clock | Input-only clock synchronized to master; defines timing for SI sampling and SO output edges |
| SI | Serial Data Input | Command/op-code/address/data input path; ignored during HOLD or when CS is high |
| SO | Serial Data Output | Read data output; tri-stated when CS is high or during HOLD assertion |
| GND | Ground Reference | Primary return path for VCC and I/O signals; requires low-impedance PCB connection |
| VCC | Power Supply | Single 2.7–5.5V supply powering logic and memory array; decoupling capacitor required near pin |
| WP | Write Protect | Hardware lock: low disables all writes regardless of WREN status or status register settings |
| HOLD | Communication Suspend | Pauses active SPI transaction without resetting address counter; requires SCK low to assert/deassert |
Key Features
| Feature | Design Value |
|---|---|
| Block Write Protection | Configurable via status register to lock 0%, 25%, 50%, or 100% of memory - prevents accidental overwrite of critical firmware parameters |
| Page Write Mode | 8-byte burst programming - reduces total write time vs. byte-by-byte writes and minimizes MCU intervention overhead |
| Self-timed Write Cycle | ≤5 ms maximum duration with no external timing control needed - simplifies firmware design and eliminates polling complexity |
| HOLD Pin Functionality | Non-disruptive pause/resume of SPI transfers - enables priority interrupt handling without losing communication context |
| Automotive-Grade Qualification | Rated −40°C to +85°C with lead-free/halogen-free construction - meets AEC-Q100 stress test requirements for automotive ECUs |

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 (16× larger), same 2.7–5.5V supply, but 5 MHz max clock at 5V (vs. 20 MHz) | Higher density for multi-parameter logging; lower speed limits real-time config updates | Select when >1Kbit storage is required and SPI bandwidth <5 MHz suffices |
| BR24G01NUX-5TR | I²C interface (not SPI), 1-Kbit size, 1.7–5.5V supply, 400 kHz max clock, 1M endurance, same TSSOP-8 footprint | Requires I²C-capable MCU; incompatible with SPI-only host designs | Choose for I²C-based systems needing identical density and package but different protocol stack |
Compared with M95128-WMN6TP and BR24G01NUX-5TR, the AT25010AN-10SI-2.7 delivers optimal balance of SPI speed (20 MHz), industrial temperature range, and compact TSSOP-8 footprint-making it ideal for resource-constrained, high-speed configuration storage where protocol and voltage compatibility are fixed constraints.

FAQ
What is the maximum SPI clock frequency supported by the AT25010AN-10SI-2.7?
The AT25010AN-10SI-2.7 supports up to 20 MHz SCK frequency when operated at VCC = 5.0V. At lower supply voltages (2.7V), the maximum clock rate decreases to 10 MHz per AC characteristics table. This ensures reliable timing margin across its full 2.7–5.5V operating range while maintaining compatibility with high-speed microcontroller SPI peripherals.
Does the AT25010AN-10SI-2.7 require an external erase cycle before writing?
No, the AT25010AN-10SI-2.7 does not require a separate erase cycle. All write operations are self-timed and automatically erase and program the target memory location within the ≤5 ms write cycle. This simplifies firmware implementation and eliminates the need for erase-status polling or additional timing overhead before each write.
How is write protection implemented on the AT25010AN-10SI-2.7?
The AT25010AN-10SI-2.7 provides dual-layer write protection: hardware-level via the WP pin (low disables all writes instantly), and software-level via BP1/BP0 bits in the status register, which can lock 0%, 25%, 50%, or 100% of the memory array. Both mechanisms operate independently-WP overrides status register settings, ensuring fail-safe data integrity.
What package type is used for the AT25010AN-10SI-2.7?
The AT25010AN-10SI-2.7 uses an 8-lead JEDEC SOIC package (8S1), 0.150" wide, with gull-wing leads. Its dimensions are 5.00 mm × 3.99 mm × 1.75 mm (L × W × H), making it compatible with standard surface-mount assembly processes and PCB footprints defined in JEDEC MS-012, Variation AA.
Can the AT25010AN-10SI-2.7 be used in automotive applications?
Yes, the AT25010AN-10SI-2.7 is qualified for automotive-grade operation across −40°C to +85°C and offered in lead-free/halogen-free variants. Its 1M write endurance, 100-year data retention, and hardware write protect (WP) pin meet functional safety requirements for noncritical automotive subsystems such as body control modules and infotainment configuration storage.
