CJMCU-PCA9685 16 channel 12 bit Fm+I2C bus PWM Controller is steering gear control module

Product Description

16 LED drive, each output can be programmed as follows:



Programmable LED brightness

Programmable set of fuzzy (dim)/flashing mix with independent LED brightness

1 MHZ rapidly mode Plus compatible on the SDA has 30 ma high drive capability of I2C bus interface to drive the high capacity bus

Each LED output can be achieved from the fully closed (the default) to full brightness level 4096 (12) between the linear programmable brightness

Software programming for open leak LED output option (the default is push-pull) 16 push-pull output (under 5 v can absorb 25 ma and provide 10 ma current), no input function

Programmable output state to change in response or stop command, in order to realize the update all at the same time the output section or word for word (byte by byte) to update the output (the default is "stop command changes")

Low effective output enable input pin, when the pin is high LED programmable output is 0, 1, or high impedance state (default on electricity as the high impedance state)

Six hardware address pins made the same I2C bus 62 PCA9685 devices can be connected

All LED output frequency (LED) usually is 40 hz to 1000 hz (when the oscillator is 25 MHZ, the default value is 1 eh preassigned frequency register will produce 200 hz refresh rate)

4 software programmable I2C bus address (an LED group Call address and three LED the son Call (Call) (Call) address) of equipment can be addressed in any combination at the same time (for example, a register is used to Call "All" (All Call) then All PCA9634 device on the I2C bus can be addressed at the same time, while the second register for three different addresses, so in a group devices on the bus a third of the equipment can be addressed at the same time), but the software can make and forbidden to the I2C bus address

Software reset feature (SWRST Call) makes the devices can be reset by I2C bus

25 MHZ crystals inside, without external components

Maximum allowable external input clock 50 MHZ

On the internal electric reset

The SDA/SCL input noise filter

Output pin edge generation rate control

Electricity without burr (glitch) output

Support hot access

Low standby current

Working voltage range: 2.3 V to 2.3 V

Can withstand 5.5 V input

Can work at minus 40 degrees Celsius to 85 degrees Celsius in the environment

HBM ESD protection more than 2000 v/JESD22 - A114, MM/JESD22 - A115 and 1000 v, 200 v CDM/JESD22 - C101

JESD78 beyond 100 ma when entering the lock test

Packaging: TSSOP28 and HVQFN28
