GPIO4
This pin may be used either as input, edge sensitive
interrupt input, or output.
This pin’s function while operating from internal ROM is
shown in Table 6.3 - GPIO Usage.
This pin may be used either as input, edge sensitive
interrupt input, or output.
This pin’s function while operating from internal ROM is
shown in Table 6.3 - GPIO Usage.
This pin may be used either as input, edge sensitive
interrupt input, or output.
This pin’s function while operating from internal ROM is
shown in Table 6.3 - GPIO Usage.
These pins may be used either as input, or output.
These pins’ functions while operating from internal ROM
are shown in Table 6.3 - GPIO Usage.
This active low signal is used by the system to reset the
chip. The active low pulse should be at least 1
μ
s wide.
These signals are used for testing the chip. User should
normally tie them high externally.
DIGITAL POWER, GROUNDS, and NO CONNECTS
VDDCORE
+1.8V Core power
All VDDCORE pins must be connected together on the
circuit board.
Pin 91 MUST have a 10uf +/- 20%, (equivalent series
resistance (ESR) <0.1ohm) bypass capacitor to VSSA,
and this capacitor should be placed as close to the pin as
possible.
VDDIO
+3.3V I/O power

Note 1:
Hot-insertion capable card connectors are required for all of flash medias. It is required for SD connector to
have Write Protect switch. This allows the chip to detect MMC card.
Note 2:
nMCE is normally asserted except when the system is in standby mode.
