The SAM4L comes in to two series; the LC and LS series. Both series are available in 48-, 64- and 100-pin options. The two series offer a slight difference in peripherals. The LC series features the LCD controller, USB Host as well as a hardware crypto module. The LS series features a USB device, but in addition offers five additional GPIO pins in all pin count options. Both series offer 128 k and 256 k Flash options for all package types. The number of I2C ports available increases with the pin count. All the other user peripherals discussed earlier not mentioned in this table are available in all devices.
