Analog VCC. Connect this pin to 3.3 V power source. This signal provides
power to the analog section of the chip.
Provide an appropriate bulk/bypass capacitance for this supply rail.
Analog VCC. Connect this pin to 3.3 V power source. This signal provides
power to the analog section of the chip.
Analog Ground. Connect this pin to ground with as short a path as possible.
Analog Ground. Connect to this pin ground with as short a path as possible.
USB D– Signal. Connect this pin to the USB D– signal.
USB D+ Signal. Connect this pin to the USB D+ signal.
Active LOW Reset. This pin resets the entire chip. See
page 6
Crystal Input. Connect this signal to a 24 MHz parallel resonant, fundamental
mode crystal and load capacitor to GND.
It is also correct to drive XTALIN with an external 24 MHz square wave derived
from another clock source.
Crystal Output. Connect this signal to a 24 MHz parallel resonant, funda-
mental mode crystal and load capacitor to GND.
If an external clock is used to drive XTALIN, leave this pin open.
CLKOUT. 12, 24, or 48 MHz clock, phase locked to the 24 MHz input clock.
The 8051 defaults to 12 MHz operation. The 8051 may tri-state this output by
setting CPUCS.1 = 1.
Multiplexed pin whose function is selected by PORTACFG.0
PA0 is a bidirectional I/O port pin.
INT0# is the active LOW 8051 INT0 interrupt input signal, which is either edge
triggered (IT0 = 1) or level triggered (IT0 = 0).
Multiplexed pin whose function is selected by PORTACFG.1
PA1 is a bidirectional I/O port pin.
INT1# is the active LOW 8051 INT1 interrupt input signal, which is either edge
triggered (IT1 = 1) or level triggered (IT1 = 0).
Multiplexed pin whose function is selected by two bits: IFCONFIG[1:0].
PA2 is a bidirectional I/O port pin.
SLOE is an input-only output enable with programmable polarity (FIFOPIN-
POLAR.4) for the slave FIFO’s connected to FD[7:0] or FD[15:0].
Multiplexed pin whose function is selected by: WAKEUP.7 and OEA.3
PA3 is a bidirectional I/O port pin.
WU2 is an alternate source for USB Wakeup, enabled by WU2EN bit
(WAKEUP.1) and polarity set by WU2POL (WAKEUP.4). If the 8051 is in
suspend and WU2EN = 1, a transition on this pin starts up the oscillator and
interrupts the 8051 to allow it to exit the suspend mode. Asserting this pin
inhibits the chip from suspending, if WU2EN = 1.
