GD25Q16ETIGR

The GD25Q16ETIGR is a 16 Mbit (2 M x 8) serial NOR Flash from GigaDevice's GD25Q16E family, running from 2.7 V to 3.6 V with standard, dual and quad SPI clocked at up to 133 MHz. Uniform 4 KB sectors, hardware and software write protection and a factory unique ID make it a mainstream code-storage device for industrial controllers, IoT nodes and networking equipment, and quad I/O reads shorten boot time without extra host pins. Package selection is the point of this exact code: in GigaDevice's ordering system the T in ETIGR denotes the narrow SOP-8 body, 150 mil (3.90 mm) wide, whereas the S in the better-known GD25Q16ESIGR denotes the 208 mil (5.30 mm) wide SOP-8. The two codes share the same die, command set and pinout, but they are not interchangeable on a laid-out footprint, so a board designed for one body width cannot accept the other. The remaining suffix letters pin the industrial -40 to +85 degree C grade, the green (lead-free) finish and tape-and-reel packing. Selection advice: check the SOP-8 body width on your BOM and land pattern before quoting - ordering ETIGR against a 208 mil footprint, or the reverse, is a line-stop mistake that a full-code check prevents.
