Brief Description
KTS1620 is a 24-bit general-purpose I/O expander via the
I2C bus for microcontrollers when additional I/Os are
needed while keeping interconnections to the minimum.
KTS1620 has separate power rails (VDD_I2C and VDD_P)
for I2C bus and I/O ports, both ranging from 1.65V to 5.5V,
allowing mixed power system where I2C bus power is not
compatible with I/O port power.
KTS1620 meets the I2C Fast-mode Plus spec up to 1MHz.
External reset input, internal power-on reset and I2C
software reset provide flexible ways to reset the IC. Four
adjustable I2C slave addresses allow multiple KTS1620s in
one I2C bus system.
KTS1620 provides multiple ways to program the 24-bit I/O
ports. When the port works as input, it can program the
polarity, latch, pull-up, pull-down and interrupt functions.
The interrupt function includes the level/edge trigger,
mask, clear, status features. For system with noisy input,
KTS1620 also provides debounce function with
programmable debounce time. When the port works as
output, it can program output stage with bank/pin
selectable push-pull or open-drain options, it can also
program four drive strengths of the output stage to optimize
the rise/fall times.
KTS1620 is available in a RoHS compliant 36-ball 2.6mm
x 2.6mm FO-WLP66 and a 32-lead 5mm x 5mm x
0.75mm Thin-QFN package.
