PCA9553 4-bit I2C LED driver

The PCA9553 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, chip set, etc.) timer. The uniqueness of this device is the internal oscillator with two programmable blink rates. To blink LEDs using norma.

PCA9553 Features

* I 4 LED drivers (on, off, flashing at a programmable rate) I 2 selectable, fully programmable blink rates (frequency and duty cycle) between 0.172 Hz and 44 Hz (5.82 seconds and 0.023 seconds) I Input/outputs not used as LED drivers can be used as regular GPIOs I Internal oscillator requires no exter
