Product details
Overview
AT25010N-10SC-2.7 from Atmel (now Microchip) is a 1-Kbit SPI serial EEPROM organized as 128 × 8-bit memory, supporting 2.7V–5.5V operation, 2.1 MHz clock rate at 5V, and hardware/software write protection via WP pin and status register. It serves as nonvolatile configuration storage in microcontroller-based industrial sensors and embedded control modules.
For engineers reviewing the AT25010N-10SC-2.7 datasheet, AT25010N-10SC-2.7 pinout, AT25010N-10SC-2.7 application, or AT25010N-10SC-2.7 equivalent, key selection criteria include low-voltage compatibility (2.7V min), 8-byte page write capability, block-level write protection (1/4, 1/2, or full array), HOLD pin for communication suspension, and JEDEC SOIC-8 packaging for space-constrained PCBs.
Technical Context
The AT25010N-10SC-2.7 operates exclusively as an SPI slave device with separate SI/SO lines, MSB-first data framing, and op-code-driven instruction set (WREN, READ, WRITE, RDSR, WRSR). Its internal architecture includes an 8-bit instruction register and nonvolatile BP1/BP0 bits controlling block write protection levels.
It features dual protection mechanisms: hardware-level inhibition via the WP pin (low = all writes blocked) and software-configurable protection through the status register, enabling selective locking of top quarter (0x60–0x7F), top half (0x40–0x7F), or entire 128-word array. All write cycles are self-timed with ≤10 ms duration and require explicit WREN prior to WRITE.
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 |
| Supply Voltage Range | 2.7V to 5.5V - enables direct interface with 3.3V and 5V microcontrollers without level shifting |
| Max Clock Frequency | 2.1 MHz at 5V - supports fast configuration reads in time-critical boot sequences |
| Write Cycle Time | ≤10 ms - deterministic latency for nonblocking firmware update routines |
| Endurance | 1 million write cycles - suitable for logging applications with frequent parameter updates |
| Data Retention | 100 years - ensures long-term reliability in unpowered industrial deployments |
| ESD Protection | >4000V HBM - robust against handling and board-level electrostatic discharge events |
Pinout & Package
AT25010N-10SC-2.7 is supplied in an 8-pin JEDEC-standard SOIC package (8S1), 0.150" wide, with gull-wing leads and standard surface-mount footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select | Active-low enable signal; must be low to accept SPI commands and drive SO output |
| SCK | Serial Clock Input | Master-generated clock synchronizing all SI/SO data transfers; supports SPI modes 0 and 3 |
| SI | Serial Data Input | Receives op-codes, addresses, and write data; ignored when CS is high or HOLD is active |
| SO | Serial Data Output | Drives read data and status register bits; enters high-impedance state when CS is high or during HOLD |
| WP | Write Protect | Hardware lock: low = all write instructions (WRITE, WRSR) rejected regardless of status register state |
| HOLD | Communication Suspend | Pauses ongoing SPI transfer without resetting address counter; requires SCK low to assert/deassert |
| VCC | Power Supply | Primary supply input (2.7–5.5V); powers internal logic and memory array |
| GND | Ground Reference | Return path for VCC and all I/O signals; must be low-impedance for reliable timing and noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| 8-byte Page Write Mode | Enables burst programming of up to 8 consecutive bytes per CS cycle, reducing total write time vs. byte-by-byte writes |
| Four-Level Block Write Protection | Status register BP1/BP0 bits allow locking 0%, 25%, 50%, or 100% of memory - prevents accidental overwrites of critical calibration data |
| Dual Write Enable Control | Combines volatile WEN bit (cleared after each write) with nonvolatile BP bits - ensures layered security for factory-programmed parameters |
| HOLD Pin Functionality | Permits pausing SPI communication mid-transfer (e.g., during MCU interrupt servicing) without losing byte alignment or address state |
| Industrial Temperature Range | -40°C to +85°C operation - validated for use in motor drives, HVAC controllers, and outdoor instrumentation |
Applications
| Industrial Sensor Calibration Storage | Medical Device Configuration Memory |
|---|---|

IC Role / Device Role / Timing Role: Low-power configuration store accessed infrequently via SPI; leverages standby current ≤100 µA at 2.7V to minimize battery drain in backup mode. Use Value: 2.7V minimum VCC allows direct connection to meter's 3.3V rail without regulator, reducing BOM cost and board area. |
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 max clock, 5ms write cycle; same SOIC-8 package and 2.5–5.5V range | Higher density and speed suit firmware patch storage; not drop-in due to different op-code set and status register layout | Select when >1Kbit memory or faster writes are required; verify SPI timing margins and command compatibility |
| 25AA010A-I/P | 1 Kbit, 10 MHz max clock, 5ms write cycle; PDIP-8 only, 1.8–5.5V range, no HOLD pin | Lacks HOLD functionality and SOIC option; better for cost-sensitive through-hole designs with simpler suspend needs | Choose for legacy through-hole assembly or where HOLD is unused; confirm absence of HOLD does not impact system interrupt handling |
Compared with M95128-WMN6TP and 25AA010A-I/P, the AT25010N-10SC-2.7 offers optimal balance of JEDEC SOIC-8 compatibility, HOLD support for real-time systems, and verified 2.7V operation - making it preferred for compact, interrupt-aware embedded designs requiring guaranteed low-voltage startup.

FAQ
What voltage range does the AT25010N-10SC-2.7 support, and how does it affect system design?
The AT25010N-10SC-2.7 supports 2.7V to 5.5V operation, enabling direct integration with both 3.3V and 5V microcontroller I/O rails without level shifters. This simplifies power architecture in mixed-voltage systems and ensures reliable startup even under brown-out conditions down to 2.7V. The device maintains full SPI functionality and write capability across this entire range, as confirmed by DC and AC characterization data in the official datasheet.
Does the AT25010N-10SC-2.7 support SPI Mode 0 and Mode 3, and how is this implemented?
Yes, the AT25010N-10SC-2.7 explicitly supports SPI Modes 0 (CPOL=0, CPHA=0) and 3 (CPOL=1, CPHA=1), as stated in its Features section. It achieves this through internal clock polarity and phase detection logic synchronized to the SCK input. The device always operates as a slave, with SI and SO pins strictly dedicated to input and output respectively - eliminating bidirectional bus contention and simplifying host driver implementation.
How does the HOLD pin function on the AT25010N-10SC-2.7, and what are its timing constraints?
The HOLD pin on the AT25010N-10SC-2.7 suspends ongoing SPI communication without resetting the internal address counter or command state. To activate HOLD, the pin must be driven low while SCK is low; to resume, it must be returned high while SCK remains low. During HOLD, SI is ignored and SO enters high-impedance. This behavior is fully characterized in the HOLD Timing diagram and enables safe MCU interrupt handling mid-transfer.
What write protection mechanisms does the AT25010N-10SC-2.7 provide, and how do they interact?
The AT25010N-10SC-2.7 provides two independent write protection layers: hardware-based inhibition via the WP pin (low = all writes blocked), and software-configurable block protection via BP1/BP0 bits in the status register. These operate orthogonally - WP overrides all software settings, while BP bits define which memory segments remain writable when WP is high. Both mechanisms are validated in functional testing and documented in Tables 3 and 4 of the datasheet.
Is the AT25010N-10SC-2.7 compatible with modern Microchip development tools and documentation?
Yes, the AT25010N-10SC-2.7 is fully supported under Microchip's product portfolio following their acquisition of Atmel. Its datasheet (document ID 0606E) remains published on microchip.com, and it is compatible with Microchip's MPLAB® ecosystem for memory testing and programming. Cross-reference tools such as Microchip's Product Selector Guide list AT25010N-10SC-2.7 under "Serial EEPROMs" with identical parametric filters and replacement guidance.
