Product details
Overview
AT25080-10PI-1.8 from Atmel (now Microchip) is a 8-Kbit SPI serial EEPROM organized as 1024 words × 8 bits, supporting 1.8V to 5.5V operation with 32-byte page write, hardware/software write protection, and 5 ms typical self-timed write cycle. It targets low-power industrial control, sensor calibration storage, and embedded configuration memory in space-constrained designs.
For engineers reviewing the AT25080-10PI-1.8 datasheet, AT25080-10PI-1.8 pinout, AT25080-10PI-1.8 application, or AT25080-10PI-1.8 equivalent, key selection considerations include its 1.8V minimum supply, SPI Mode 0/3 compatibility, block-level write protection (1/4–full array), HOLD/ WP pin functionality, and PDIP-8 packaging for through-hole prototyping and legacy board compatibility.
Technical Context
The AT25080-10PI-1.8 operates as an SPI slave device with separate SI (input) and SO (output) pins, requiring CS activation and MSB-first data framing. Its instruction set includes WREN/WRDI for write enable/disable, RDSR/WRSR for status register access, and READ/WRITE for memory access - all synchronized to SCK with no external erase cycle needed.
It implements nonvolatile status register bits (BP0/BP1/WPEN) to configure block write protection and hardware write protect enable, while HOLD suspends ongoing serial transfers without resetting the sequence. The device supports full read/write operation across its entire 1024-word address space with automatic address increment during sequential reads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 8 Kbit (1024 × 8-bit words) - fixed capacity for compact firmware parameter or calibration storage |
| Supply Voltage | 1.8 V to 5.5 V - enables direct interface with 1.8V, 2.7V, 3.3V, and 5V microcontrollers without level shifting |
| Max Clock Frequency | 3.0 MHz at 5V - supports high-speed programming in production test and fast configuration loads |
| Page Write Size | 32 bytes - balances write speed and endurance by limiting per-cycle write burst size |
| Write Cycle Time | 5 ms typical - defines minimum interval between write commands; impacts system responsiveness during config updates |
| Endurance | 1 million write cycles - ensures long-term reliability in field-updatable systems with frequent parameter changes |
| Data Retention | 100 years - guarantees persistent storage of critical settings over product lifetime without refresh |
Pinout & Package
AT25080-10PI-1.8 uses an 8-lead PDIP (0.300" wide) package, suitable for breadboarding, manual soldering, and legacy PCB layouts. Pin 1 is CS (Chip Select), with standard SPI signal mapping and dedicated WP/HOLD control lines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select | Active-low enable: initiates SPI communication only when pulled low; high-Z SO when deasserted |
| SCK | Serial Clock | Master-generated clock input; timing reference for SI/SO data sampling (Mode 0/3 compatible) |
| SI | Serial Data Input | Receives op-codes, addresses, and write data; ignored unless CS is low and device is write-enabled |
| SO | Serial Data Output | Drives read data or status bits; high-impedance when CS high or during HOLD suspension |
| GND | Ground Reference | Return path for VCC and all I/O signals; must be low-impedance for stable SPI timing and noise immunity |
| VCC | Power Supply | 1.8–5.5 V supply; powers internal logic and memory array; decoupling capacitor required near pin |
| WP | Write Protect | Hardware lock: disables status register writes when low + WPEN=1; prevents accidental configuration corruption |
| HOLD | Communication Suspend | Pauses active SPI transfer without resetting state; allows master to service higher-priority interrupts |
Key Features
| Feature | Design Value |
|---|---|
| SPI Mode 0 & 3 Support | Interoperates with diverse MCUs including 68HC11, PIC, ARM Cortex-M, and ESP32 without protocol translation |
| Block Write Protection | Configurable via status register to lock 0%, 25%, 50%, or 100% of memory - secures bootloader or factory defaults |
| Hardware + Software Write Protection | Combines WP pin (physical lock) and WREN/WRDI instructions (logical control) for layered data integrity assurance |
| Self-Timed Write Cycle | No external timing circuitry needed; internal oscillator manages 5 ms erase/write - simplifies host firmware design |
| HOLD Pin Functionality | Enables deterministic pause/resume of multi-byte transfers - critical for real-time systems with interrupt latency constraints |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| M95080-DRMN3TP/K | 8-Kbit SPI EEPROM, 1.8–5.5V, but uses 8-lead SOIC (MSL3) vs. PDIP; tWC = 5 ms typical same; no HOLD pin | Lacks HOLD functionality; SOIC footprint requires rework for through-hole designs; better for automated SMT assembly | Select when board uses SOIC and HOLD is unnecessary; verify WP pin behavior matches system-level protection scheme |
| BR24G08FJ-3GE2 | 8-Kbit I²C EEPROM (not SPI); 1.7–5.5V; 400 kHz max clock; no WP/HOLD pins; different command set and addressing | Requires I²C bus instead of SPI; incompatible protocol layer; no hardware suspend or block protection granularity | Choose only if migrating from I²C architecture; redesign required for interface, timing, and protection logic |
Compared with M95080-DRMN3TP/K and BR24G08FJ-3GE2, the AT25080-10PI-1.8 uniquely delivers HOLD capability and PDIP-8 packaging for prototyping, while maintaining identical 8-Kbit density and 1.8V operation - making it optimal for legacy-compatible, interrupt-aware, or hand-soldered designs.

FAQ
What is the operating voltage range of the AT25080-10PI-1.8?
The AT25080-10PI-1.8 operates from 1.8 V to 5.5 V, enabling direct integration with 1.8V, 2.7V, 3.3V, and 5V logic families. This dual-voltage capability eliminates level-shifting requirements in mixed-supply systems and supports battery-powered applications down to 1.8V nominal.
Does the AT25080-10PI-1.8 support SPI Mode 0 and Mode 3 only?
Yes, the AT25080-10PI-1.8 explicitly supports SPI Modes 0 (CPOL=0, CPHA=0) and 3 (CPOL=1, CPHA=1), as confirmed in its official datasheet. It does not support Mode 1 or Mode 2; attempting those configurations will result in communication failure or undefined behavior.
How does the HOLD pin function during an active SPI transaction?
The HOLD pin on the AT25080-10PI-1.8 suspends serial communication when pulled low while SCK is low, preserving the current address and instruction state. Communication resumes when HOLD returns high while SCK remains low - allowing deterministic pause/resume without restarting the command sequence.
What is the maximum write endurance and data retention for the AT25080-10PI-1.8?
The AT25080-10PI-1.8 guarantees 1 million write cycles and 100 years of data retention at 25°C, as specified in its datasheet. These values are measured under standard conditions (5V, 25°C, page-mode writes) and represent minimum rated performance across the industrial temperature range.
Can the AT25080-10PI-1.8 be used in automotive applications?
The AT25080-10PI-1.8 is rated for industrial temperature (-40°C to +85°C) and is not qualified to AEC-Q100 automotive standards. While it may function in some under-hood or cabin environments, Microchip offers automotive-grade variants (e.g., AT25080-MAPI-1.8) with full qualification - use those for certified automotive deployments.
