16-bit I²C-bus LED driver with programmable blink rates

The PCA9552 LED blinker blinks LEDs in I²C-bus and SMBus applications where it is necessary to limit bus traffic or free up the I²C-bus master's (MCU, MPU, DSP, chipset, etc.) timer. The uniqueness of this device is the internal oscillator with two programmable blink rates. To blink LEDs using norma • 16 LED drivers (on, off, flashing at a programmable rate)\n• 2 selectable, fully programmable blink rates (frequency and duty cycle) between 0.172 Hz and 44 Hz (5.82 seconds and 0.023 seconds)\n• Input/outputs not used as LED drivers can be used as regular GPIOs\n• Internal oscillator requires no ;
