16-bit I2C LED driver with programmable blink rates

DESCRIPTION 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 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

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 ;
