This 8-bit I/O expander for the two-line bidirectional bus (I
2C) is designed for 2.3-V to 5.5-V VCC operation. It
provides general-purpose remote I/O expansion for most microcontroller families via the I
2C interface [serial
clock (SCL), serial data (SDA)].
The PCA9538 consists of one 8-bit Configuration (input or output selection), Input Port, Output Port, and Polarity
Inversion (active high or active low) registers. At power on, the I/Os are configured as inputs. However, the
system master can enable the I/Os as either inputs or outputs by writing to the I/O configuration bits. The data
for each input or output is kept in the corresponding Input Port or Output Port register. The polarity of the Input
Port register can be inverted with the Polarity Inversion register. All registers can be read by the system master.
The system master can reset the PCA9538 in the event of a timeout or other improper operation by asserting a
low in the RESET input. The power-on reset puts the registers in their default state and initializes the I
2C/SMBus
state machine. The RESET pin causes the same reset/initialization to occur without powering down the part.
The PCA9538 open-drain interrupt (INT) output is activated when any input state differs from its corresponding
Input Port register state and is used to indicate to the system master that an input state has changed.
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 I
2C bus. Thus, the PCA9538 can remain a simple slave device.
The device outputs (latched) have high-current drive capability for directly driving LEDs. It has low current
consumption.
