3 Device Comparison

Table 1 and Table 2 do not provide an all-encompassing feature list. It is intended to show differences between the devices in order to know which sections of this document apply to your specific device. Features common to all devices such as EMIF16, 1GbE Switch, general-purpose input/output (GPIO), inter-integrated circuit (I2C), serial peripheral interface (SPI), universal asynchronous receiver/transmitter (UART), and so forth are not shown. The chart is color coded to emphasize the groups of devices that are pin-for-pin compatible.
