Full Universe, 512 Channels
The IS3715 is an I2C DMX Controller chip. You write values to its internal memory map via I2C and it continuously outputs them as DMX data at 44 Hz.
The chip features 512 8-bit RAM registers to store DMX channel values, which can be written to like a typical I2C EEPROM. It continuously outputs all memory as DMX data, so you only need to write via I2C when values change, keeping your microcontroller relaxed.
The I2C-Serial interface operates as a slave and supports 100 kHz, 400 kHz, and 1 MHz communication speeds.
The IS3715 frees your microcontroller from the DMX protocol timing constraints, memory requirements, and ISR load associated with generating DMX data, reducing the need for timers, flash, and RAM. It also eliminates the need for dedicated pins by operating over a shared I2C.
The device operates at 3.3 V, with 5 V-tolerant I2C, enabling compatibility with 3.3 V or 5 V microcontrollers. It is offered in Industrial (–40 °C to +85 °C) and Extended (–40 °C to +125 °C) temperature ranges.
