68HC08EYxx Family Introduction
Specifically designed for LIN applications
that require an internal clock generator
without the cost of additional external
components, EY devices are also suited for
applications in which the flexibility of
automotive Flash or low-cost ROM is
required in memory sizes from 4K鈥?6K. This
family is offered in the small 7mm x 7mm
32QFP package, ideal when available board
space for the MCU is minimal.
ENHANCED SCI鈥擫IN SCI CONTROLLER
Programmable 8-bit or 9-bit character length
Programmable baud rates
Separately enabled transmitter and receiver
Interrupt-driven operation with eight
interrupt flags
鈥?Capable of communication rates up to
115,000 bps, encompassing all LIN baud rates

鈥?Full-duplex operation allows simultaneous
transmission and reception of data
鈥?ESCI arbiter allows measurement of LIN
synchronization data without separate timer
hardware
鈥?Finely adjustable baud rate prescalers allow
extremely precise control of baud rate
鈥?Enhanced detection of LIN break symbols
to prevent false interrupts
INTERNAL CLOCK GENERATOR
鈥?< 0.4% oscillator accuracy within a LIN frame
鈥?Fully trimmable oscillator from -40擄C
to 125擄C
鈥?Software-selectable bus frequencies up
to 8 MHz
鈥?Clock monitor
鈥?Eliminates the cost of external clock
components (crystal or resonator)
鈥?Reduces board space
鈥?Minimizes or reduces EMI generated from
external clocks
