Product details

64 Mbit SPI NOR Flash for firmware and data-logging storage

The S25FS064SAGBHI020: Organized as 8M x 8 bits, the 64 Mbit density suits firmware images, parameter storage, and boot code for MCU-based designs where NOR Flash provides reliable random-access read performance.

Interface speed and memory organization — what they mean for throughput

At this speed, the effective read throughput reaches approximately 66 MB/s in quad-output mode, sufficient for fast boot and execute-in-place (XIP) code execution without external RAM caching. The 8M x 8 organization means the memory is byte-addressable in 8-bit words, matching the bus width of most MCU SPI peripherals. The 64 Mbit capacity leaves headroom for a firmware image plus a small file system or calibration data table.

Supply voltage and temperature grade — deployment envelope

Rated for a 1.7 V supply, this part operates from a single low-voltage rail, making it suitable for battery-powered portable devices and 1.8 V logic systems.

Frequently asked questions

What is the closest functional alternative to S25FS064SAGBHI020?

The S25FL064LABNFI010 is a 64 Mbit SPI NOR Flash from the FL-L series with the same 8M x 8 organization and -40°C to +85°C temperature range, but it operates at 2.7 V supply and 108 MHz clock, versus the FS-S part's 1.7 V and 133 MHz. None are pin-compatible drop-in replacements without checking the supply voltage and temperature requirements of the design.
