Features and benefits
400 kHz I2C-bus serial interface
Compliant with I2C-bus Standard-mode (100 kHz)
Separate supply rails for core logic and I/O bank provides voltage level shifting
1.1 V to 3.6 V operation with level shifting feature
Very low standby current: < 1
μA
8 configurable I/O pins that default to inputs at power-up
Outputs:
Totem pole: 1 mA source and 3 mA sink
Independently programmable 100 k
Ω pull-up or pull-down for each I/O pin
Open-drain active LOW interrupt (INT) output pin allows monitoring of logic level
change of pins programmed as inputs
Inputs:
Programmable bus hold provides valid logic level when inputs are not actively
driven
Programmable Interrupt Mask Control for input pins that do not require an interrupt
when their states change or to prevent spurious interrupts default to mask at
power-up
Polarity inversion register allows inversion of the polarity of the I/O pins when read
Active LOW reset (RESET) input pin resets device to power-up default state
GPIO All Call address allows programming of more than one device at the same time
with the same parameters
2 programmable slave addresses using 1 address pin
40 °C to +85 °C operation
ESD protection exceeds 7000 V HBM per JESD22-A114 and 1000 V CDM per
JESD22-C101
Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA
Packages offered: TSSOP16, HVQFN16 and XQFN16
