NAND Flash Controller (NFC) Timing
The i.MX25 NFC supports normal timing mode, using two Flash clock cycles for one access of RE and
WE. AC timings are provided as multiplications of the clock cycle and fixed delay. Figure 34 through
Figure 37 depicts the relative timing between NFC signals at the module level for different operations
under normal mode. Table 55 describes the timing parameters (NF1–NF17) that are shown in the figures.

2 SDRAM CLK and DQS-related parameters are measured from the 50% point. That is, high is defined as 50% of the signal
value, and low is defined as 50% of the signal value. DDR SDRAM CLK parameters are measured at the crossing point of
SDCLK and SDCLK (inverted clock).
3 The value was calculated for an SDCLK frequency of 133 MHz, by the formula tQH = tHP – tQHS = min. (tCL,tCH) – tQHS =
0.45*tCK – tQHS = 0.45 * 7.5 – 0.45 = 2.925 ns
