Frequently Asked Questions
How does the 25AA080A-I/ST's 1,000,000 write cycle endurance affect its suitability for data-logging applications?
With 1,000,000 write/erase cycles guaranteed, the 25AA080A-I/ST can sustain a write every 31 seconds continuously for 10 years before approaching its endurance limit. For typical embedded data-logging at 1 write per minute, this translates to nearly 2 years of useful life, and using wear-leveling across the 8 Kbit address space effectively multiplies this by the ratio of total bytes to written bytes per cycle.
What SPI clock speed does the 25AA080A-I/ST support, and does it operate at 1.8 V without level shifters?
The 25AA080A-I/ST supports SPI clock frequencies up to 10 MHz and operates natively from 1.8 V supply, eliminating the need for level-shift circuitry when paired with modern 1.8 V microcontrollers such as ARM Cortex-M0+ or RISC-V MCUs. This direct interface reduces BOM cost and board complexity in low-power wearable and sensor designs.
For a space-constrained PCB, how does the 25AA080A-I/ST's TSSOP-8 package compare to a DIP-8 alternative?
The 25AA080A-I/ST's TSSOP-8 package occupies roughly 19 mm² of board area with a 0.65 mm lead pitch, compared to approximately 73 mm² for a DIP-8. This 74% footprint reduction is critical in handheld devices and wearables where every square millimeter matters. The TSSOP-8 is also compatible with standard reflow soldering, avoiding the wave-solder or hand-soldering requirements of through-hole DIP packages.
