8-bit I2C LED driver with programmable blink rates

DESCRIPTION The PCA9551 LED Blinker blinks LEDs in I2C-bus and SMBus applications where it is necessary to limit bus traffic or free up the I2 C Master’s (MCU, MPU, DSP, chipset, etc.) timer. The uniqueness of this device is the internal oscillator with two programmable blink rates. FEATUR

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

The PCA9551 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 ? 8 LED drivers (on, off, flashing at a programmable rate)\n? 2 selectable, fully programmable blink rates (frequency and duty cycle) between 0.148 Hz and 38 Hz (6.74 seconds and 0.026 seconds)\n? Input/outputs not used as LED drivers can be used as regular GPIOs\n? Internal oscillator requires no e;
