The GreenPAK is a cost effective programmable mixed signal FPGA that can integrate many discrete ICs into a single device. It can be configured by the user and programmed in minutes using design software. GreenPAK is ideal for replacing microcontrollers and integrating various functions like logic, voltage monitoring, and resets, reducing component count. It comes in small 2x2mm or 2.5x2.5mm packages and over 45 million have shipped since 2009.
