Electrical Characteristics

This section provides the relative timing requirements among various signals of NFC at the module level,
in each operational mode.
Timing parameters in
NFC mode (asymmetric mode) using two Flash clock cycles per one access of RE_B and WE_B.
Timing parameters in
NFC mode using one Flash clock cycle per one access of RE_B and WE_B.
With reference to the timing diagrams, a high is defined as 80% of signal value and low is defined as 20%
of signal value. All parameters are given in nanoseconds. The BGA contact load used in calculations is
20 pF (except for NF16 - 40 pF) and there is maximum drive strength on all contacts.
All timing parameters are a function of T, which is the period of the flash_clk clock (“enfc_clk” at system
level). This clock frequency can be controlled by the user, configuring CCM (SoC clock controller). The
clock is derived from emi_slow_clk after single divider.

For RBB_MODE=1, using NANDF_RB0 signal for ready/busy indication. This mode require setting the delay line. See the
Reference Manual for details.
T
mode is 398 cycles of divided reference clock when DPLL starts after full reset.
Tdck is the time period of the output clock, dpdck_2.
emi_slow_clk (MHz)
dpdref
100 (Boot mode)
is the time period of the reference clock after predivider. According to the specification, the maximum lock time in FOL
demonstrates several examples of clock frequency settings.

NAND Flash Controller (NFC) Parameters
A potential limitation for minimum clock frequency may exist for some
devices. When the clock frequency is too low, the data bus capturing might
occur after the specified t
clock frequency above 25.6 MHz (that is, T = 39 ns) guaranties a proper
operation for devices having t
NFC_FREQ_SEL Fuse be set accordingly to initiate the boot with
33.33 MHz clock.
