S08EL and S08SL 8-bit microcontrollers with embedded Slave LIN Interface Controller (SLIC) and EEPROM help to increase LIN slave performance and reduce development time. Freescale Semiconductor’s 8-bit EL and SL families of microcontrollers (MCUs) are designed for LIN slave and general market applications. The EL family is positioned as higher end, offering higher memory and more peripherals, while the SL family is intended for more cost-sensitive applications. An application focus area of the EL and SL families is Local Interconnect Network (LIN). LIN is a UART-based, single-master, multiple-slave networking architecture originally developed for automotive sensor and actuator networking applications.
