Freescale 8-bit microcontrollers enhance performance and accuracy for automotive and industrial designs

EL and SL MCU families designed for higher performance and reduced development cost and time-to-market for LIN applications

PARIS (Freescale Technology Forum) – Oct. 7, 2008 – Freescale Semiconductor has introduced the EL and SL microcontroller (MCU) families to help embedded designers improve system performance in automotive Local Interconnect Network (LIN) and general market applications. Based on Freescale’s widely used S08 core, the EL and SL families provide a highly integrated 8-bit solution designed to reduce development time and cost.

The EL family offers increased memory and peripherals, while the SL family targets cost-sensitive applications. The 8-bit devices are ideal for developers requiring higher performance for a wide range of automotive LIN applications, such as light sensors, sunroofs, seat position motors, control panels and door locks.

The EL and SL devices feature embedded EEPROM, on-chip emulation/debug and an advanced embedded slave LIN interface controller (SLIC) module. Unique to Freescale, SLIC technology enhances system performance by automating message handling and is designed to outperform other MCU implementations for LIN slave applications. On-chip EEPROM helps reduce system cost and development time by enabling developers to manipulate diagnostic data at byte level, which provides finer granularity with smaller sector sizes than flash memory implementations.

Operating at up to 40 MHz, the EL and SL devices offer exceptional 8-bit performance with the fewest CPU interrupts of any comparable 8-bit LIN solution. The EL and SL MCUs offer scalable performance and pin compatibility across space-saving TSSOP packages.
