85 MHz clock and write timings — what they mean on the bench
The 85 MHz clock is the SPI bus speed. Page program time is 8 µs for a word, 6 ms for a full page.
No end-of-life notice, no last-time-buy deadline.
Package and mounting — 8-SOIC wide body
The 8-SOIC package (0.209" body width, 5.30 mm) is the wide-body SOIC. It is a surface-mount part, so it goes through reflow. The wide body gives better thermal dissipation than the narrow SOIC if you are running it at high temperature. Cut Tape works for prototype or small-run builds.
