External Capacitors for Power Supplies
– High quality 2.2 μF capacitors must be
connected to CEXT1 and 2 for proper operation of the chip.
CEXTA
Power Supply/Ground
External Capacitor for Analog Power Supply
– A high quality 0.33 μF capacitor
must be connected to CEXTA for proper operation of the chip.
XTAL1
Input
Oscillator Input
– Input to the inverting oscillator amplifier.
XTAL2
Output
Oscillator Output
– Output of the inverting oscillator amplifier.
CPUSEL
Input
CPU Speed Select
– This pin selects the CPU clock frequency. If high, the CPU
runs at 12 MHz, if low it runs at 24 MHz.
LFT
Input
PLL Filter
– For proper operation of the PLL, this pin should be connected through
a 0.01 μF capacitor in parallel with a 100
resistor in series with a 0.1 μF capacitor
to ground (VSS). Both capacitors must be high quality ceramic.
DPO
Bi-directional
Upstream Plus USB I/O
– This pin should be connected to CEXT1 through an
external 1.5 k

DMO
Bi-directional
Upstream Minus USB I/O
DP[2,3]
Bi-directional
Downstream Plus USB I/O
– Each of these pins should be connected to VSS
through an external 15 k
resistor. DP[2,3] and DM[2,3] are the differential signal
pin pairs to connect downstream USB devices.
DM[2,3]
Bi-directional
Downstream Minus USB I/O
– Each of these pins should be connected to VSS
through an external 15 k
resistor.
PA[0:7]
Bi-directional
Port A[0:7]
– Bi-directional 8-bit I/O port with 2 mA drive strength and a
programmable pull-up resistor.
PD[0:6]
Bi-directional
Port D[0:6]
– Bi-directional I/O ports with 2 mA drive strength and a programmable
pull-up resistor. PortD[2,3,5,6] have dual functions as shown below:
