Technical Details & Description

512 Kbit SPI Flash in an 8-SOIC — what it fits

The Microchip SST25VF512-20-4C-SAE-T is a 512 Kbit serial Flash memory using the SPI interface, organized as 64K x 8.

20 MHz SPI — throughput for code shadowing

The 20 MHz SPI clock delivers a raw serial read rate of 20 Mbit/s, enough to shadow a small firmware image into an MCU's RAM or serve configuration data to a display controller. The 20 µs page write time keeps the programming window short for the 512 Kbit array — useful when the host processor has a tight polling loop.

Frequently asked questions

What is the difference between SST25VF512-20-4C-SAE-T and SST25VF512-20-4C-SAE?

The -T suffix indicates Tape & Reel packaging for automated pick-and-place assembly; the non-T variant ships in tube or tray. The die, performance, and pinout are identical.

Can SST25VF512-20-4C-SAE-T replace SST25VF512-20-4C-SAE?

Yes — the -T suffix is purely a packaging indicator (Tape & Reel). The electrical and mechanical specifications are the same, so it is a drop-in replacement for the tube version in a reel-fed assembly line.

What is the closest functional second-source for SST25VF512-20-4C-SAE-T?

It is pin-compatible in the same 8-SOIC footprint but offers higher speed and wider temperature — check your firmware image size before substituting.
