Product details
Overview
AT25080A-10TI-1.8 from Microchip Technology (formerly Atmel) is an 8-Kbit SPI serial EEPROM organized as 1024 × 8 bits, supporting 1.8V–5.5V operation, 20 MHz clock rate at 5V, 32-byte page write, and hardware/software write protection via WP pin and status register. It serves as nonvolatile configuration storage in industrial controllers, sensor nodes, and power management ICs.
For engineers reviewing the AT25080A-10TI-1.8 datasheet, AT25080A-10TI-1.8 pinout, AT25080A-10TI-1.8 application, or AT25080A-10TI-1.8 equivalent, key selection criteria include low-voltage compatibility (1.8V min), automotive-grade temperature range (−40°C to +85°C), TSSOP-8 packaging, block write protection granularity, and self-timed 5 ms max write cycle.
Technical Context
The AT25080A-10TI-1.8 operates as a SPI slave device with dedicated SI/SO pins, supports Modes 0 and 3, and uses MSB-first transmission. Its internal architecture includes an 8-bit instruction register handling WREN, WRITE, RDSR, WRSR, and READ op-codes.
Block write protection is implemented via nonvolatile BP0/BP1 bits in the status register, enabling protection of 0%, 25%, 50%, or 100% of the memory array. The HOLD pin suspends ongoing serial communication without resetting the sequence, while WP enables hardware-level inhibition of status register writes when WPEN = 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 8 Kbit (1024 × 8), sufficient for firmware patch storage or calibration data in compact embedded systems |
| Supply Voltage Range | 1.8 V to 5.5 V - enables direct interface with 1.8V logic and mixed-voltage microcontrollers |
| Max Clock Frequency | 20 MHz at 5V - supports high-throughput configuration reads in real-time control loops |
| Write Cycle Time | 5 ms maximum - defines minimum interval between successive page writes in logging applications |
| Endurance | 1 million write cycles - ensures >10 years of daily reconfiguration in industrial field devices |
| Data Retention | 100 years at 25°C - guarantees long-term integrity of stored calibration coefficients or security keys |
| Operating Temperature | −40°C to +85°C - meets industrial grade requirements for deployment in harsh ambient environments |
Pinout & Package
AT25080A-10TI-1.8 is housed in an 8-lead Thin Shrink Small Outline Package (TSSOP), 0.170" wide, with 0.65 mm pitch, optimized for space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select | Active-low enable signal; must be low to accept SPI commands and data |
| SCK | Serial Clock | Input-only clock; synchronizes all SI/SO data transfers per SPI protocol |
| SI | Serial Data Input | Receives op-codes, addresses, and write data; ignored when CS is high |
| SO | Serial Data Output | Drives read data and status bits; enters high-impedance state when CS is high or HOLD is active |
| WP | Write Protect | Hardware lock for status register writes when WPEN = 1; prevents accidental configuration corruption |
| HOLD | Communication Suspend | Pauses ongoing SPI transfer without resetting address counter; requires SCK low to assert |
| VCC | Power Supply | 1.8–5.5 V supply; powers internal logic and memory array; decoupling capacitor required |
| GND | Ground Reference | Return path for all I/O and core circuitry; must be low-impedance connection to system ground plane |
Key Features
| Feature | Design Value |
|---|---|
| 32-byte Page Write | Enables efficient burst programming of configuration blocks without per-byte overhead |
| Four-Level Block Protection | Allows selective locking of 0%, 25%, 50%, or 100% of memory via BP0/BP1 bits |
| Hardware + Software Write Protection | Combines WP pin control with WRSR-configurable protection for defense-in-depth data security |

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 | STMicroelectronics 8-Kbit SPI EEPROM; identical 1.8–5.5 V range, 20 MHz max, TSSOP-8 package, but uses different status register bit mapping and lacks HOLD pin | Supports same industrial temperature range but requires firmware adaptation for status register access and no suspend capability | Select when HOLD functionality is unused and ST's qualification ecosystem is preferred |
| BR24G08FJ-3GE2 | Rohm 8-Kbit SPI EEPROM; 1.7–5.5 V range, 10 MHz max clock, TSSOP-8, integrated write protect logic but no separate WP pin | Lower speed limits use in high-bandwidth logging; integrated WP reduces BOM count but removes hardware-level status register lock | Select for cost-sensitive designs where 10 MHz suffices and simplified board layout outweighs flexibility loss |
Compared with M95080-DRMN3TP/K and BR24G08FJ-3GE2, the AT25080A-10TI-1.8 uniquely combines 20 MHz performance, explicit HOLD pin for real-time interrupt handling, and independent WP pin control over status register writes-critical for robust field-upgradeable systems.

FAQ
What is the operating voltage range of the AT25080A-10TI-1.8?
The AT25080A-10TI-1.8 operates from 1.8 V to 5.5 V, making it compatible with both 1.8V logic families and legacy 3.3V/5V systems. This dual-range capability eliminates level-shifting requirements in mixed-voltage designs and ensures stable operation across varying input conditions encountered in industrial power rails.
Does the AT25080A-10TI-1.8 support hardware write protection?
Yes, the AT25080A-10TI-1.8 supports hardware write protection via its dedicated WP (Write Protect) pin. When the WPEN bit in the status register is set to "1", pulling WP low disables all writes to the status register-including BP0/BP1 bits-preventing accidental modification of memory protection settings during system operation.
What package type is used for the AT25080A-10TI-1.8?
The AT25080A-10TI-1.8 uses an 8-lead Thin Shrink Small Outline Package (TSSOP), designated as 8A2 in Microchip's ordering nomenclature. This surface-mount package measures 3.0 mm × 4.4 mm with 0.65 mm lead pitch, offering high-density placement and thermal performance suitable for compact industrial PCBs.
How many write cycles can the AT25080A-10TI-1.8 endure?
The AT25080A-10TI-1.8 guarantees 1 million write cycles per memory location under specified conditions (5.0 V, 25°C, page mode). This endurance rating ensures reliable operation in applications requiring frequent reconfiguration, such as adaptive control systems or field-upgradable firmware storage, over multi-year deployments.
Is the AT25080A-10TI-1.8 qualified for automotive applications?
The AT25080A-10TI-1.8 is rated for industrial temperature (−40°C to +85°C) and offered in lead-free/halogen-free variants, but it is not AEC-Q100 qualified. For automotive applications requiring formal qualification, Microchip offers the AT25080B-MAHL-T (AEC-Q100 Grade 3) as a drop-in alternative with identical pinout and electrical behavior.
