The last devices to be discussed in the Lx series are the L38x and L3Ax groups. The L38x supports up to 352 segments in a 44x8 configuration and adds four extra A/D inputs compared to the L36x 64-pin version. The L3Ax is the largest option in the Lx Series. It supports up to 416 segments, offers 20 A/D inputs and up to 88 GPIO. Both groups also offer Data Flash as an option. As with all R8C/Lx groups, these devices include timer functionality (8- and 16-bit) and multiple serial interfaces including UART, clock synchronous, SPI, and I²C.
