GD25Q21BxIGx Uniform Sector Dual and Quad Serial Flash
2. GENERAL DESCRIPTION
http://www.elm-tech.com
The GD25Q21B Serial flash supports the standard Serial Peripheral Interface (SPI), and a high performance
Dual/Quad output as well as Dual/Quad SPI: Serial Clock, Chip Select, Serial Data I/O0 (SI), I/O1 (SO), I/O2
(WP#), and I/O3 (HOLD#). SPI clock frequencies of up to 104MHz are supported allowing equivalent clock
rates of 208MHz for Dual Output & Dual I/O read command, and 416MHz for Quad output & Quad I/O read
command.
