8-bit EEPROM with LIN S08EL and S08SL MCUs

S08EL-SL

S08EL and S08SL 8-bit microcontrollers with embedded Follower LIN Interface Controller (SLIC) and EEPROM help to increase LIN follower performance and reduce development time. NXP® Semiconductors's 8-bit EL and SL families of microcontrollers (MCUs) are designed for LIN follower 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-leader, multiple-follower networking architecture originally developed for automotive sensor and actuator networking applications.
