General-purpose media interface (GPMI) timing

The i.MX 8M Plus GPMI controller is a flexible interface NAND Flash controller with 8-bit data width,

up to 200 MB/s I/O speed and individual chip select.

It supports Asynchronous Timing mode, Source Synchronous Timing mode and Toggle Timing mode

separately, as described in the following subsections.

3.8.5.1

Asynchronous mode AC timing (ONFI 1.0 compatible)

Asynchronous mode AC timings are provided as multiplications of the clock cycle and fixed delay. The

maximum I/O speed of GPMI in Asynchronous mode is about 50 MB/s. Figure 28 through Figure 31

depicts the relative timing between GPMI signals at the module level for different operations under

Asynchronous mode. Table 50 describes the timing parameters (NF1–NF17) that are shown in the figures.
