Description: characteristic 16 LED drivers, each output programmable as: turn off programmable LED brightness programmable group dim/flicker and independent LED brightness mixing 1MHz fast mode Plus is compatible with I2C bus interface with 30mA high drive capability on SDA to drive high capacity bus Each LED output can achieve 4096 levels (12 bits) of linear programmable brightness from full off (default) to brightness 16 push-pull outputs that can be programmed as open-drain LED output selection (default is push-pull) (can absorb 25mA draw current and provide 10mA draw current at 5V), without input function The output status can be programmed to change when answering or stopping the command to realize simultaneous update of all outputs or byte-by-byte update of output (the default is "stop command change") Low effective output enable input pin. When the pin is high, LED output can be programmed to 0, 1 or high resistance state (power-on defaults to high resistance state) Six hardware address pins enable 62 PCA9685 devices to be connected on the same I2C bus LED output frequency (all LEDs) is usually 40Hz to 1000Hz (when the oscillator is 25MHz, the default value of the prescaler register is 1EH, which will generate a refresh frequency of 200Hz) Four software-programmable I2C bus addresses (one LED group call address and three LED sub-call address) enable the device group to be addressed at the same time in any combination (for example, if a register is used for "All Calls", then all PCA9634 devices on the I2C bus can be addressed at the same time, and the second register is used for three different addresses, Then 1/3 of the devices on the bus in a device group can be addressed at the same time), and I2C bus address can be enabled and disabled by software Software reset feature (SWRST Call) enables the device to be reset via I2C bus 25MHz internal crystal oscillator without external devices Allow 50MHz external input clock Internal power-on reset With noise filter at SDA/SCL input Output pin has edge generation rate control No glitch output when powered on Support hot access Low standby current Working voltage range: 2.3V to 5.5V Can withstand 5.5V input It can work in the environment from minus 40 ℃ to 85 ℃
