Product details
Overview
AT25010-10PC-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, 8-byte page write mode, and hardware/software write protection via WP pin and status register. It serves as nonvolatile configuration storage in microcontroller-based industrial control modules.
For engineers reviewing the AT25010-10PC-2.7 datasheet, AT25010-10PC-2.7 pinout, AT25010-10PC-2.7 application, or AT25010-10PC-2.7 equivalent, key selection considerations include VCC operating range compatibility, SPI mode 0/3 support, block write protection granularity, self-timed 10 ms write cycle, and PDIP/SOIC package availability for legacy board designs.
Technical Context
The AT25010-10PC-2.7 operates as an SPI slave device with dedicated SI (input), SO (output), SCK (clock), and CS (chip select) pins, requiring MSB-first 8-bit op-code + address + data framing. Its internal architecture includes a nonvolatile status register with BP1/BP0 bits enabling 1/4, 1/2, or full-array write protection independent of WP pin state.
It implements automatic address incrementing during page writes, supports HOLD pin suspension of ongoing transfers without sequence reset, and enforces write enable (WREN) and disable (WRDI) instructions - all while maintaining high-impedance SO during CS high or HOLD active states.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 1024 bits (128 × 8-bit words) - fixed capacity for compact firmware parameter or calibration storage. |
| Interface | SPI-compatible, modes 0 (CPOL=0, CPHA=0) and 3 (CPOL=1, CPHA=1) - ensures interoperability with 68HC11, PIC, and ARM Cortex-M MCUs. |
| VCC Range | 2.7V to 5.5V - enables direct integration into mixed-voltage systems without level-shifting. |
| Max Clock Rate | 2.1 MHz at 5V - supports fast read/write cycles in time-critical boot or logging applications. |
| Write Cycle Time | 10 ms max - defines minimum interval between successive write operations; no external erase needed. |
| Endurance & Retention | 1 million write cycles / 100 years data retention - suitable for field-updatable devices with long service life. |
| Protection | Hardware (WP pin) + software (status register BP bits) - allows layered security for critical configuration blocks. |
Pinout & Package
AT25010-10PC-2.7 is supplied in 8-pin PDIP (package code 8P3), 0.300" wide, through-hole compatible with legacy prototyping and industrial PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select | Active-low enable signal; must be low to accept SI data and drive SO output. |
| SCK | Serial Clock | Master-generated clock input; timing reference for SI sampling and SO output edges. |
| SI | Serial Data Input | Asynchronous data input path for op-codes, addresses, and write data (MSB first). |
| SO | Serial Data Output | Tri-state output for read data; high-impedance when CS high or HOLD active. |
| GND | Ground Reference | Return path for VCC and all I/O signals; requires low-impedance connection to system ground plane. |
| VCC | Power Supply | Single supply input (2.7–5.5V); powers internal logic and memory array. |
| WP | Write Protect | Hardware lock: low = inhibit all write operations regardless of status register or WREN state. |
| HOLD | Communication Suspend | Pauses ongoing SPI transfer without resetting address counter; requires SCK low to assert/deassert. |
Key Features
| Feature | Design Value |
|---|---|
| 8-byte page write mode | Reduces average write time per byte by batching up to eight sequential locations in one CS cycle. |
| Four-level block write protection | Enables selective locking of top quarter (60–7Fh), top half (40–7Fh), or entire array (00–7Fh) via nonvolatile BP bits. |
| Self-timed internal write cycle | Eliminates need for external delay timers or polling overhead beyond RDSR status checking. |
| HOLD pin suspend capability | Allows master MCU to temporarily halt EEPROM communication during interrupt servicing without losing context. |
| ESD protection >4000V | Meets HBM Class 3A requirements, reducing risk of damage during handling or system-level ESD events. |
Applications
| Industrial Sensor Calibration Storage | Consumer Appliance Configuration Memory |
|---|---|
Use Scenario: Storing factory-trimmed sensor offset/gain coefficients and temperature compensation tables in HVAC or pressure transmitters. IC Role / Device Role / Timing Role: Nonvolatile configuration storage accessed during power-on initialization and periodic recalibration routines. Use Value: Enables field-replaceable sensor modules with persistent calibration data across 100-year retention and 1M-cycle endurance. |
Use Scenario: Holding user preferences (e.g., cooking time, temperature presets, language settings) in microwave ovens and washing machines. IC Role / Device Role / Timing Role: Low-power, SPI-accessed parameter store updated infrequently but retained across AC power cycles. Use Value: Supports 2.7V operation during brown-out conditions and withstands repeated write cycles from menu navigation events. |
| Embedded Controller Bootloader Settings | Medical Device Usage Log Storage |
Use Scenario: Storing bootloader jump vectors, firmware version flags, and secure boot keys in programmable logic controllers (PLCs). IC Role / Device Role / Timing Role: Secure, write-protected memory segment accessed only during firmware update or cold start sequences. Use Value: Block protection prevents accidental overwrite of critical boot parameters; WP pin adds hardware-level lockdown. |
Use Scenario: Recording timestamped operational events (e.g., sterilization cycles, alarm triggers) in portable diagnostic equipment. IC Role / Device Role / Timing Role: Low-overhead, deterministic write target for real-time logging with minimal CPU intervention. Use Value: 10 ms max write time ensures log entries complete before next event, and 100-year retention meets medical device archival requirements. |
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 | 1-Kbit SPI EEPROM, 2.5–5.5V VCC, 10 MHz max clock, 5 ms write cycle, SOIC-8 only. | Higher speed and lower write latency, but lacks PDIP option and HOLD pin functionality. | Select when board space is constrained and faster write throughput is required; verify absence of HOLD does not impact host timing. |
| 25AA010A-I/P | 1-Kbit SPI EEPROM, 1.8–5.5V VCC, 10 MHz max clock, 5 ms write cycle, PDIP-8 and SOIC-8 available. | Broadest voltage range and fastest clock, but no HOLD pin and different status register bit mapping. | Prefer for new designs needing ultra-low-voltage support down to 1.8V; revalidate write protection logic against AT25010-10PC-2.7. |
Compared with AT25010-10PC-2.7, M95010-WMN6TP offers higher speed but sacrifices HOLD functionality and PDIP packaging, while 25AA010A-I/P extends voltage range and speed but requires redesign of protection and suspend logic due to architectural differences.

FAQ
What is the maximum clock frequency supported by AT25010-10PC-2.7 at 3.3V operation?
The AT25010-10PC-2.7 supports up to 2.1 MHz at 5.0V, but its AC characteristics specify 2.1 MHz only for VCC = 4.5–5.5V and 2.1 MHz for VCC = 2.7–5.5V - meaning 2.1 MHz is valid at 3.3V. This is confirmed in the AC Characteristics table (page 4), where fSCK Max = 2.1 MHz applies across the 2.7–5.5V range. The device maintains full timing compliance without derating at 3.3V.
Does AT25010-10PC-2.7 support SPI mode 1 (CPOL=0, CPHA=1) or mode 2 (CPOL=1, CPHA=0)?
No, AT25010-10PC-2.7 explicitly supports only SPI modes 0 (CPOL=0, CPHA=0) and 3 (CPOL=1, CPHA=1), as stated in the Features section. Mode 1 and mode 2 are not electrically or functionally compatible due to mismatched sampling/setting edges relative to SCK transitions. Attempting mode 1 or 2 will result in corrupted data reads/writes.
How does the HOLD pin interact with an ongoing WRITE command on AT25010-10PC-2.7?
The HOLD pin suspends serial communication but does not interrupt an internal write cycle already initiated. If HOLD is asserted during a WRITE sequence (after CS goes high to launch the write), the device completes the 10 ms self-timed write. HOLD only affects SPI signaling - it freezes SCK/CS/SI timing but leaves the internal EEPROM programming engine unaffected.
Can AT25010-10PC-2.7 be used in automotive applications?
AT25010-10PC-2.7 is rated for commercial temperature range (0°C to +70°C) and is not qualified for automotive AEC-Q100 stress testing. While the datasheet notes "Automotive Grade and Extended Temperature Devices Available" for the family, the -10PC-2.7 suffix specifically denotes commercial-grade PDIP packaging. For automotive use, select variants like AT25010-10PI-2.7 (industrial grade, –40°C to +85°C) or automotive-qualified equivalents.
What happens if the WP pin is pulled low during a WREN instruction on AT25010-10PC-2.7?
The AT25010-10PC-2.7 ignores the WREN instruction entirely when WP is low, regardless of CS or SCK state. The Write Enable Latch remains unset, and subsequent WRITE commands will be rejected. This behavior is documented in the Functional Description section: "The WP pin must be held high during a WREN instruction." No status flag change occurs; the device stays in write-disabled state.
