General description
The NCA9539-Q100 provides 16 bits of General Purpose Input/Output (GPIO) expansion with
interrupt and reset for I²C-bus/SMBus applications. It is designed for a wide voltage range of
1.65 V to 5.5 V. Nexperia GPIO expanders provide an elegant solution when additional IOs are
needed while keeping the interconnections to a minimum, for example, in ACPI power switches,
sensors, push buttons, LEDs and fan control. The NCA9539-Q100 contains a set of 8 bit input,
output, configuration and polarity inversion registers. At power up all IOs default to inputs. Each IO
can be configured as either input or output by changing the corresponding bit in the configuration
register. The data for each input or output is stored in the corresponding input or output register.
The polarity inversion register can be programmed to invert the polarity of the read register. The
NCA9539-Q100 has an open-drain interrupt output which is activated when any one of the GPIO
changes from its corresponding input port register state. INT can be connected to the interrupt
input of a microcontroller. By sending an interrupt signal on this line, the remote I/O can inform the
microcontroller if there is incoming data on its ports without having to communicate via the I²Cbus.
Thus, NCA9539-Q100 can remain a simple slave. The power on reset sets the registers to
default values and initializes the device state machine. The RESET pin can be used to achieve
same reset functionality without power down/up cycling by keeping active low. The state machine
and the registers are in their default state until the RESET input is once again HIGH. This input
requires pull up to VCC. The NCA9539-Q100 has two address pins A0 and A1 which can be used
to configure the I²C bus slave address of the device. It allows up-to four devices to share the same
I²C-bus/SMBus.
This product has been qualified to the Automotive Electronics Council (AEC) standard Q100
(Grade 1) and is suitable for use in automotive applications.
