AT25080B-XHL-T 58BL Serial EEPROM - Memory for Industrial and Commercial Applications

AT25080B-XHL-T 58BL Serial EEPROM | High-Reliability 8 Kbit (1024 × 8) SPI Serial EEPROM with 32-Byte Page Mode and 20 MHz Clock Rate for Industrial and Commercial Embedded Applications and ASIC Configuration Storage

The AT25080B-XHL-T 58BL is a high-reliability serial Electrically Erasable Programmable Read-Only Memory (EEPROM) designed for industrial and commercial embedded applications. With an organization of 8,192 bits (8 Kbit) split into 1,024 words of 8 bits each, the AT25080B provides ample storage for critical configuration data, calibration constants, serial numbers, and other non-volatile parameters that must survive power cycles.

Optimised for low power consumption and low-voltage operation — well-suited to battery-backed and power-sensitive embedded designs. Communicates via a standard 3-wire SPI interface (SI / SO / SCK) plus chip-select, integrating cleanly with any SPI-equipped microcontroller (STM32, PIC, AVR, ESP32, etc.). Supports SPI modes 0 and 3, with clock rates up to 20 MHz at 5V for fast read / write operations. 32-byte page mode enables efficient bulk writes vs single-byte operations.

Typical Applications

• ASIC miner configuration storage — calibration constants, hashboard serial numbers, factory parameters.
• Industrial control systems — PLC parameter storage, drive configurations.
• Embedded device serial numbers — non-volatile device identity for product traceability.
• Sensor calibration storage — non-volatile cal tables for industrial sensors.
• Boot configuration storage — boot loader parameters for microcontroller-based systems.
• Battery-backed RAM replacement — non-volatile storage without backup battery complexity.

FAQ — AT25080B-XHL-T Serial EEPROM

Q: AT25080B vs I²C-based EEPROM — which to choose?
A: SPI EEPROMs like AT25080B offer faster clock rates (20 MHz vs typical 1 MHz for I²C) and cleaner pin separation (SI/SO/SCK/CS) at the cost of more pins. For high-bandwidth or system-bus-shared designs, SPI wins. For simple low-bandwidth use with many devices on one bus, I²C is more practical. The AT25080B fits SPI-equipped embedded systems where speed and pin separation matter.

Q: How many write cycles does it tolerate?
A: Standard EEPROM endurance is ~1 million write cycles per byte (typical for AT25080B family). For high-frequency-write applications (>1 write/second 24/7), consider FRAM or other higher-endurance non-volatile memory. For configuration storage (write occasionally, read frequently), EEPROM is the standard choice.

Q: Will my SPI library handle the 32-byte page mode automatically?
A: Most SPI EEPROM libraries (Arduino, STM32 HAL, etc.) handle page-mode writes natively, splitting writes that cross page boundaries automatically. For custom firmware, ensure your write routine respects the 32-byte page boundary — writes that cross boundaries silently wrap, corrupting unrelated data.
