Input Write protect signal
FC_RESET Input
Reset processor. RESET# low resets the processor to the
initial state and halts all activity. RESET# must be low for
at least one cycle. On a transition from low to high, a Reset
exception occurs and the processor starts execution at the
Reset entry determined by the INT4 state. The transition
may occur asynchronously to the clock. We recommend
connecting this pin to a voltage monitoring circuit with
open-drain output (e.g. Torex XC61A) supplying a reset
signal for supply voltages less than 2.6 or 2.7V, connected
to a R/C combination of 100 kΩ and 100 nF giving an
additional reset delay in the order of 10 ms.
FC_LED\ Output Operation LED signal
FC_MODE
FC_IDEEN Output Master/Slave select and connect to IDE_CSEL for Cable
select option
XTALR Output R/C Clock Oscillator Resistor Output. The resistor
connected between this pin and XTALI determines the
operating clock frequency. Use a 470Ω resistor to obtain a
frequency of about 20 MHz
XTALC Output R/C Clock Oscillator Capacitor Output. Connect a 22pF
capacitor between this pin and XTALI.
XTALI Input R/C Clock Oscillator Input. This input connects to the other
side of the resisors and the capacitor connected to XTALR1,
XTALR2 and XTALC. Connect a 22pF capacitor from this pin
to ground.

Vcc_R Supply Power Supply Voltage, Regulator
Vcc_F Supply Power Supply Voltage, Flash Memory
Vcc_P Supply Power Supply Voltage, controller
FADJ Input 3.3V Flash Memory Power Supply Adjustment. Connect a
270pF capacitor from this pin to FOUT.
FOUT Output 3.3V Flash Memory Power Supply. This output provides a
regulated 3.3V supply if the power supply voltage is above
3.3V. This supply voltage must also be connected to the
VCC_F pins.
CADJ Input 2.5V Core Power Supply Adjustment. Connect a 220kΩ
resistor from this pin to GND, a 220kΩ resistor from this
pin to COUT, and a 270pF capacitor from this pin to COUT.
COUT Output 2.5V Core Power Supply. This output provides a regulated
2.5V supply if the power supply voltage is above 3.3V. This
supply voltage must be connected to the VCC_C pins.
VccNAND_IN Supply 3.3V Flash Memory Power Supply
VccPLN_IN Supply Supply to the controller
GndPLN Supply Supply ground
