Product details
Overview
AT25010N-10SC from Atmel (now Microchip) is a 1-Kbit SPI serial EEPROM organized as 128 × 8-bit memory, operating from 2.7V to 5.5V, supporting 2.1 MHz clock rate at 5V, and featuring hardware write protection via WP pin and 8-byte page write capability. It serves as nonvolatile configuration storage in microcontroller-based industrial control modules requiring low-voltage operation and robust data retention.
For engineers reviewing the AT25010N-10SC datasheet, AT25010N-10SC pinout, AT25010N-10SC application, or AT25010N-10SC equivalent, key selection criteria include VCC range compatibility (2.7–5.5V), SOIC-8 package footprint, SPI Mode 0/3 timing compliance, block-level write protection granularity, and 10 ms max self-timed write cycle performance.
Technical Context
The AT25010N-10SC implements a synchronous slave SPI interface with dedicated SI/SO pins, CS-controlled selection, and HOLD pin for communication suspension without sequence reset. Its instruction set includes WREN/WRDI for software write enable/disable and RDSR/WRSR for status register access and BP1/BP0-configurable block protection (1/4, 1/2, or full array).
Internally, it uses an 8-bit instruction register with MSB-first data transfer, automatic address increment during sequential read, and page-write logic that increments the three LSBs of the address while holding the six MSBs constant-enabling 8-byte burst writes within a single page boundary.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 1024 bits (128 words × 8 bits), sufficient for firmware calibration tables or device ID storage in space-constrained designs |
| Supply Voltage Range | 2.7V to 5.5V - supports dual-rail systems and brown-out tolerant operation without external level shifters |
| Max Clock Frequency | 2.1 MHz at 5V - enables fast configuration loading in host MCU boot sequences |
| Write Cycle Time | 10 ms maximum - defines minimum interval between successive write commands; no external erase needed |
| Endurance | 1 million write cycles - ensures reliable logging or parameter update over 10+ years in field-deployed equipment |
| Data Retention | 100 years at 25°C - guarantees long-term integrity of stored calibration or security keys without refresh |
| Write Protection | Hardware (WP pin) + software (status register BP1/BP0 bits) - enables layered protection against accidental or malicious overwrite |
Pinout & Package
AT25010N-10SC is supplied in an 8-pin JEDEC SOIC (8S1) package, 0.150" wide, with standard gull-wing lead form and 1.27 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select | Active-low enable signal; must be low to accept instructions; high-Z SO when CS high |
| SCK | Serial Clock Input | Master-generated clock; defines timing for SI sampling and SO output; supports SPI Modes 0 and 3 |
| SI | Serial Data Input | Receives op-codes, addresses, and write data; MSB-first, synchronized to SCK falling edge |
| SO | Serial Data Output | Drives read data and status bits; high-impedance when CS high or HOLD active |
| GND | Ground Reference | Signal and power return path; must be low-impedance to minimize noise on SPI lines |
| VCC | Power Supply | 2.7–5.5V supply; decoupling capacitor required near pin to suppress switching transients |
| 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 internal state; requires SCK low during assertion |
Key Features
| Feature | Design Value |
|---|---|
| SPI Mode 0 & 3 Compatibility | Interoperates with common MCUs (e.g., AVR, PIC, ARM Cortex-M) without protocol translation or glue logic |
| 8-Byte Page Write | Reduces write latency by up to 8× vs. byte-wise writes; eliminates need for external buffering in firmware |
| Four-Tier Block Protection | Enables selective locking of top quarter/half or entire array via nonvolatile BP1/BP0 bits - ideal for bootloader-safe parameter zones |
| Self-Timed Write Cycle | Removes requirement for host MCU to manage erase/write timing; simplifies driver code and improves system predictability |
| 100-Year Data Retention | Validated at 25°C; ensures stored calibration coefficients, MAC addresses, or licensing tokens remain intact across product lifetime |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| M95010-WMN6TP | STMicroelectronics 1-Kbit SPI EEPROM; identical 2.7–5.5V range and SOIC-8 package but rated for 5 MHz max clock (vs. 2.1 MHz) | Higher-speed read/write suitable for time-critical boot loaders; same pinout and instruction set as AT25010N-10SC | Select when faster configuration load time is required and host MCU supports >2.1 MHz SCK |
| 25AA010A-I/P | Microchip 1-Kbit SPI EEPROM; same family origin (post-Atmel acquisition), 1.8–5.5V range, 10 ms write cycle, but only offers 1/4-array protection (no 1/2 or full) | Limited block protection scope reduces flexibility for multi-zone secure storage; otherwise drop-in compatible | Select when broader voltage headroom (down to 1.8V) is needed and full-array protection is not required |
Compared with M95010-WMN6TP and 25AA010A-I/P, the AT25010N-10SC provides finer-grained write protection (1/4, 1/2, or full array) and guaranteed 2.1 MHz operation at 5V, making it optimal for industrial systems where memory partitioning and deterministic timing outweigh raw speed or ultra-low-voltage support.

FAQ
What is the maximum clock frequency supported by the AT25010N-10SC?
The AT25010N-10SC supports up to 2.1 MHz SCK frequency when operated at 4.5–5.5V, 2.1 MHz at 2.7–5.5V, and 0.5 MHz at 1.8–3.6V. These values are specified in the AC Characteristics table and validated across the full industrial temperature range (-40°C to +85°C). The AT25010N-10SC does not guarantee operation above 2.1 MHz even at 5V.
Does the AT25010N-10SC require an external erase command before writing?
No, the AT25010N-10SC does not require a separate erase command. All programming cycles are self-timed and fully integrated: a WRITE instruction automatically handles both erase and program phases internally. The AT25010N-10SC completes the entire operation in ≤10 ms, after which the RDY bit in the status register clears to indicate readiness for the next command.
How does the WRITE PROTECT (WP) pin interact with software write protection on the AT25010N-10SC?
The WP pin provides hardware-level override protection: when pulled low, it inhibits all write operations-including WREN, WRSR, and WRITE-regardless of the status register's WEN or BP bits. If WP is high, software protection (via BP1/BP0) remains active. The AT25010N-10SC treats WP as the highest-priority lock, ensuring fail-safe data integrity in fault conditions.
Can the AT25010N-10SC be used in SPI Mode 1 or Mode 2?
No, the AT25010N-10SC explicitly supports only SPI Modes 0 (CPOL = 0, CPHA = 0) and 3 (CPOL = 1, CPHA = 1), as stated in its Features section. Attempting to use Mode 1 or Mode 2 will result in incorrect data sampling or output timing, because the device's SI setup/hold and SO valid windows are characterized only for those two modes. The AT25010N-10SC is not compatible with Mode 1 or Mode 2 clocks.
What is the purpose of the HOLD pin on the AT25010N-10SC?
The HOLD pin allows the host MCU to temporarily suspend an ongoing SPI transaction without resetting the internal address counter or instruction state. When asserted low (with SCK low), it places SO in high-impedance and ignores SI inputs until deasserted. This enables priority interrupt handling or bus arbitration in multi-master systems. The AT25010N-10SC resumes exactly where it left off upon HOLD release.
