Functional Overview
The CY7C63413C/513C/613C are 8-bit RISC One Time
Programmable (OTP) microcontrollers. The instruction set has
been optimized specifically for USB operations, although the
microcontrollers can be used for a variety of non-USB
embedded applications.
The CY7C63413C/513C features 32 General-Purpose I/O
(GPIO) pins to support USB and other applications. The I/O
pins are grouped into four ports (Port 0 to 3) where each port
can be configured as inputs with internal pull-ups, open drain
outputs, or traditional CMOS outputs. The CY7C63413C/513C
have 24 GPIO pins (Ports 0 to 2) that are rated at 7 mA typical
sink current. The CY7C63413C/513C has 8 GPIO pins (Port
3) that are rated at 12 mA typical sink current, which allows
these pins to drive LEDs.
The CY7C63613C features 16 General-Purpose I/O (GPIO)
pins to support USB and other applications. The I/O pins are
grouped into four ports (Port 0 to 3) where each port can be
configured as inputs with internal pull-ups, open drain outputs,
or traditional CMOS outputs. The CY7C63613C has 12 GPIO
pins (Ports 0 to 2) that are rated at 7 mA typical sink current.
The CY7C63613C has 4 GPIO pins (Port 3) that are rated at
12 mA typical sink current, which allows these pins to drive
LEDs.
Multiple GPIO pins can be connected together to drive a single
output for more drive current capacity. Additionally, each I/O
pin can be used to generate a GPIO interrupt to the microcon-
troller. Note the GPIO interrupts all share the same “GPIO”
interrupt vector.
The CY7C63513C features an additional 8 I/O pins in the DAC
port. Every DAC pin includes an integrated 14-Kohm 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 can
be used as an input with an
internal pull-up by writing a
“1” to the pin.
