Description
The ACE25AA400G is 4M-bit Serial flash supports the standard Serial Peripheral Interface (SPI). and supports the Dual/Quad SPI: Serial Clock, Chip Select, Serial Data I/O0 (SI), I/O1 (SO), I/O2 (WP#), and I/O3 (HOLD#). The Dual I/O data is transferred with speed of 216Mbits/s and the Quad I/O & Quad output data is transferred with speed of 432Mbits/s.
