Functional Overview
The CY7C66013C and CY7C66113C are compound devices
with a full speed USB microcontroller in combination with a USB
hub. Each device is 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 I/O 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 I/O 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 I/O pins (DAC).
Every DAC pin includes an integrated 14 k pull up resistor.
When a ‘1’ is written to a DAC I/O 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 I/O pin, the internal pull
up is disabled and the output pin provides the programmed
amount of sink current. A DAC I/O pin is used as an input with
an internal pull up by writing a ‘1’ to the pin.
The sink current for each DAC I/O 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 I/O
pin is used to generate a DAC interrupt to the microcontroller.
Also, the interrupt polarity for each DAC I/O pin is individually
programmable.
