GreenPak comparator comes with I2C interface
The SLG46811 integrates traditional GreenPAK programmable logic with shift register macrocells, a multichannel sampling analog comparator and a 92 by 8bit pattern generator, all within a small 1.6mm by 1.6mm package.
Generally GreenPak devices are programmable devices that combine analog, mixed-signal and power circuits with status and configuration stored in non-volatile memory. Where the SLG46811 fits the application, it will consume less power and occupy less PCB than a solution made of multiple components.
