3 Description
The TCAL9539R device provides general purpose
parallel input/output (I/O) expansion for the two-line
bidirectional I2C bus (or SMBus) protocol and is
designed for 1.08V to 3.6V VCC operation.
The device supports 100kHz (Standard-mode),
400kHz (Fast-mode), and 1MHz (fast-mode-plus)
I2C clock frequencies. I/O expanders such as the
TCAL9539R provide a simple solution when additional
I/Os are needed for switches, sensors, push-buttons,
LEDs, fans, and so on.
The TCAL9539R has Agile I/O ports which include
additional features designed to enhance the I/O
performance in terms of speed, power consumption
and EMI. The additional features are: programmable
output drive strength, programmable pull-up and pulldown
resistors, latchable inputs, maskable interrupt,
interrupt status register, and programmable opendrain
or push-pull outputs.
The RESET pin only resets the I2C state machine
when stuck to regain access to the I2C. I/O pins and
sticky registers retain the last configured state while
the I2C is being re-initialized.
