Overview
S08EL and SL 8-bit microcontrollers with
embedded slave Local Interconnect Network
(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.
Typical Applications of the EL
and SL Families
An application focus area of the EL and SL
families is LIN. LIN is a UART-based, single-
master, multiple-slave networking architecture
originally developed for automotive sensor
and actuator networking applications.

Features
The EL and SL families offer up to 40 MHz
of CPU performance using Freescale’s 0.25µ
flash to push the boundaries of 8-bit into the
range of 16-bit MCU performance. The EL
and SL families are scalable and offer pin
compatibility across packages.
The EL and SL families provide on-chip
EEPROM and a unique, embedded SLIC
module. SLIC automates message handling
to help increase performance, shorten
development time and reduce cost.
SLIC Increases Performance
• Trueautosynchronizationandautobauding
finds LIN frames and adjusts baud rate
without CPU intervention
• Numberofinterruptsreducedbyupto83
percent over UART solutions—only two
interrupts per LIN message
• Remaininginterruptsareserviced
much more efficiently due to interrupt
handling technology
• OutstandingLINbusnoisesuppression
to UART—SLIC blocks noise instead of
passing it on
• CanuseSYNCHdatafromLINmessages
to trim oscillator
• SLICeliminatesmanystepsnormally
required by UART solutions (trim oscillator,
detect break, measure sync signal, adjust
baud rate, calculate and verify checksum,
handle individual data bytes, detect
LIN errors)
SLIC Shortens Development Time
• Byeliminatingmessageprocessingsteps,
SLIC minimizes and simplifies driver code
• SLICdrivercodeassmallas120bytes
possible (refer to AN2633)
• Simplerdrivercodemeansshortened
debug and development time—use your
engineering time to debug the application,
not LIN communication
SLIC Helps Reduce Cost
• SLICcanhandleanyLINspeedonanyLIN
bus with only one software driver required,
which allows for:
Code reuse for many applications,
regardless of LIN bus speed—no
reprogramming required to change bus
speeds means fewer part numbers to
track and stock
High-speed (up to 120 kpbs), end-of-line
programming through LIN allows faster
module manufacturing times and field
reprogrammability
• Smallerdrivercodemeanslessflash
required for given application—use flash for
your application, not LIN communication
• SLICdoesnotrequireoscillatortrimming,
unlike UART or bit-banged LIN solutions,
eliminating a manufacturing step
