PCA9552 Description
PCA9552 16-bit I2C-bus LED driver with programmable blink rates Rev.5.1 * 25 May 2023 Product data sheet 1 General .
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 controller's (.
PCA9552 Features
* 16 LED drivers (on, off, flashing at a programmable rate)
* 2 selectable, fully programmable blink rates (frequency and duty cycle) between 0.172 Hz and 44 Hz (5.82
seconds and 0.023 seconds)
* Input/outputs not used as LED drivers can be used as regular GPIOs
* Int
PCA9552 Applications
* where it is necessary to limit bus traffic or free up the I2C-bus controller'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 normal I/O expanders like the PCF8574 or PCA9554, the bus controller m
