18-GPIO, 6 ACMPs, 3 DCMPs/PWMs, 2 DACs, 26 LUTs (max.), 10 CNT/DLY (max.), 12 DFF/LATCH (max.) and other Macrocells
The SLG46620 provides a small, low power component for commonly used mixed-signal functions. The user creates their circuit design by programming the one time Non-Volatile Memory (NVM) to configure the interconnect logic, the I/O Pins and the macro cells of the SLG46620. This highly versatile device allows a wide variety of mixed-signal functions to be designed within a very small, low power single integrated circuit.
