Product details
Overview
AT25010N-10SI from Atmel (now Microchip) is a 1-Kbit SPI serial EEPROM organized as 128 words × 8 bits, operating from 2.7V to 5.5V, supporting SPI modes 0 and 3, with 2.1 MHz max clock rate at 5V, and integrated hardware write protection via WP pin - used for nonvolatile configuration storage in industrial microcontroller systems.
For engineers reviewing the AT25010N-10SI datasheet, AT25010N-10SI pinout, AT25010N-10SI application, or AT25010N-10SI equivalent, key selection criteria include industrial temperature range (−40°C to +85°C), 8-byte page write capability, self-timed 10 ms write cycle, block write protection (1/4, 1/2, or full array), and JEDEC SOIC-8 package compatibility.
Technical Context
The AT25010N-10SI implements a synchronous SPI slave interface with dedicated SI (input), SO (output), SCK (clock), and CS (chip select) pins, requiring MSB-first data transfer and op-code–driven instruction execution (e.g., READ, WRITE, WREN, RDSR). It uses an 8-bit instruction register and supports HOLD pin suspension without sequence reset.
Its status register (BP1/BP0 bits) controls nonvolatile block write protection across four memory segments; write enable state (WEN bit) must be set before programming, and RDY bit indicates internal write cycle completion. All writes are self-timed with no external erase step required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 1024 bits (128 × 8), sufficient for small firmware config tables or calibration data storage |
| Supply Voltage Range | 2.7V to 5.5V - enables direct interfacing with 3.3V and 5V microcontrollers without level shifting |
| Max Clock Frequency | 2.1 MHz at 5V - supports fast read/write in time-critical boot or logging sequences |
| Write Cycle Time | 10 ms maximum - deterministic timing for host software timeout handling |
| Endurance | 1 million write cycles - suitable for frequent parameter updates in field-deployed equipment |
| Data Retention | 100 years at 25°C - ensures long-term reliability in unattended industrial installations |

Pinout & Package
AT25010N-10SI is supplied in an 8-pin JEDEC-standard SOIC package (8S1), 0.150" wide, surface-mount compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select | Active-low enable: initiates SPI communication only when low; high-Z SO during CS high |
| SCK | Serial Clock | Master-generated clock input; device operates as SPI slave with no internal clock generation |
| SI | Serial Data Input | Receives op-codes, addresses, and write data; sampled on SCK rising edge (mode 0) |
| SO | Serial Data Output | Drives read data and status bits; tri-stated when CS high or during HOLD assertion |
| WP | Write Protect | Hardware lock: disables all write operations when pulled low, independent of status register |
| HOLD | Communication Suspend | Pauses ongoing SPI transfer without resetting address counter or losing context |
| VCC | Power Supply | 2.7–5.5V operation; decoupling capacitor required per layout guidelines |
| GND | Ground Reference | Return path for all I/O and supply currents; must be low-impedance connection |
Key Features
| Feature | Design Value |
|---|---|
| SPI Mode 0 & 3 Compatibility | Interoperates with 68HC11, PIC, ARM Cortex-M, and other common MCU SPI peripherals without mode translation logic |
| 8-Byte Page Write | Reduces total write time vs. byte-by-byte programming - critical for minimizing host CPU blocking duration |
| Block Write Protection (BP1/BP0) | Enables selective locking of top quarter (0x60–0x7F), top half, or full 128-word array via nonvolatile status register |
| Hardware + Software Write Protection | WP pin provides immediate physical lockout; WREN/WRDI instructions add runtime control granularity |
| HOLD Pin Functionality | Allows real-time interruption of SPI transfers (e.g., during interrupt servicing) without losing command state or address pointer |
Applications
| Industrial PLC Configuration Storage | Medical Device Calibration Data |
|---|---|

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, 20 MHz SPI, 1.8–5.5V, built-in write cycle counter, no HOLD pin | Higher density and speed; lacks HOLD functionality needed for interrupt-safe transfers | Select when larger storage or faster throughput is required and HOLD is not used in design |
| 25AA1024-I/P | 1 Mbit capacity, 10 MHz SPI, 1.8–5.5V, 5 ms typical write cycle, no WP pin - relies solely on software protection | Greater memory depth but missing hardware write lock; requires additional firmware safeguards | Choose for cost-sensitive designs where hardware WP is not mandated by safety or security policy |
Compared with AT25010N-10SI, M95128-WMN6TP offers higher bandwidth and density but removes HOLD support essential for deterministic interrupt handling, while 25AA1024-I/P trades hardware write protection for increased capacity and reduced write latency - making AT25010N-10SI optimal for resource-constrained industrial systems needing guaranteed hardware-level data integrity.

FAQ
What is the operating voltage range of the AT25010N-10SI?
The AT25010N-10SI operates from 2.7V to 5.5V, supporting both 3.3V and 5V logic systems without level shifters. This dual-voltage capability is confirmed in the DC Characteristics table (VCC2 min/max), and the "-2.7" suffix in the part number explicitly denotes this low-voltage variant. The device maintains full functionality-including 2.1 MHz SPI clock rate and 10 ms write cycle-across the entire range.
Does the AT25010N-10SI support hardware write protection?
Yes, the AT25010N-10SI includes a dedicated Write Protect (WP) pin that, when driven low, disables all write operations regardless of status register settings or WREN instruction state. This hardware lock is active even during power-up and provides fail-safe protection against unintended writes due to noise or firmware errors - a feature explicitly documented in the "WRITE PROTECT" section and Pin Configurations diagram.
What package type is used for the AT25010N-10SI?
The AT25010N-10SI uses an 8-lead JEDEC-standard SOIC package (designated 8S1), 0.150" wide, with gull-wing leads. This is confirmed in the "Package Type" section and "AT25010 Ordering Information" table, where "AT25010N-10SI" maps to the 8S1 option. The "N" in the part number denotes the SOIC variant, distinguishing it from the PDIP version (AT25010-10PI).
Can the AT25010N-10SI be used in automotive applications?
The AT25010N-10SI is rated for industrial temperature (−40°C to +85°C) and features automotive-grade qualification per the datasheet's "Automotive Grade and Extended Temperature Devices Available" statement. While not AEC-Q100 certified out-of-box, its electrical specs - including ESD >4000V, robust VCC tolerance, and HOLD/WP functionality - align with common automotive subsystem requirements such as body control and infotainment configuration storage.
How does the HOLD pin function on the AT25010N-10SI?
The HOLD pin on the AT25010N-10SI suspends ongoing SPI communication without resetting the internal address counter or command state. When asserted low while SCK is low, it places SO in high-impedance and ignores SI inputs; resuming requires bringing HOLD high while SCK remains low. This behavior is fully specified in the "HOLD" subsection of "Serial Interface Description" and enables safe interrupt handling in real-time systems using AT25010N-10SI.
