Functional Overview
The CY7C66013C and CY7C66113C are compound devices
with a full speed USB microcontroller in combination with a USB
hub. Each device is well suited for combination peripheral
functions with hubs such as a keyboard hub function. The 8-bit
one time programmable microcontroller with a 12 Mbps USB
Hub supports as many as four downstream ports.

GPIO
The CY7C66013C features 29 GPIO pins to support USB and
other applications. The IO pins are grouped into four ports
(P0[7:0], P1[7:0], P2[7:0], P3[4:0]) where each port is configured
as inputs with internal pull ups, open drain outputs, or traditional
CMOS outputs. Ports 0 to 2 are rated at 8 mA per pin (typical)
sink current. Port 3 pins are rated at 12 mA per pin (typical) sink
current, which allows these pins to drive LEDs. Multiple GPIO
pins are connected together to drive a single output for more
drive current capacity. Additionally, each IO pin is used to
generate a GPIO interrupt to the microcontroller. All of the GPIO
interrupts all share the same “GPIO” interrupt vector.
The CY7C66113C has 31 GPIO pins (P0[7:0], P1[7:0], P2[7:0],
P3[6:0]).

DAC
The CY7C66113C has an additional port P4[7:0] that features an
additional eight programmable sink current IO pins (DAC). Every
DAC pin includes an integrated 14-kΩ pull up resistor. When a
‘1’ is written to a DAC IO pin, the output current sink is disabled
and the output pin is driven HIGH by the internal pull up resistor.
When a ‘0’ is written to a DAC IO pin, the internal pull up is
disabled and the output pin provides the programmed amount of
sink current. A DAC IO pin is used as an input with an internal
pull up by writing a ‘1’ to the pin.
The sink current for each DAC IO pin is individually programmed
to one of sixteen values using dedicated Isink registers. DAC bits
DAC[1:0] is used as high current outputs with a programmable
sink current range of 3.2 to 16 mA (typical). DAC bits DAC[7:2]
have a programmable current sink range of 0.2 to 1.0 mA
(typical). Multiple DAC pins are connected together to drive a
single output that requires more sink current capacity. Each IO
pin is used to generate a DAC interrupt to the microcontroller.
Also, the interrupt polarity for each DAC IO pin is individually
programmable.
