HC08 QC Family
Overview
Freescale Semiconductor’s QC family of
microcontrollers (MCUs) is positioned to
support HC08 core small-package 8-bit
microcontrollers for general market use.
The QC family is ideal for the low-end
Local Interconnect Network (LIN) market.
The functionality is completed with strong
analog capabilities, a complete set of serial
modules and robust memory options.
These products are fully LIN 2.0 and J2602
compliant. They are intended to be used as
LIN slaves where the application requires
cost-effective hardware solutions. A variety of
small packages (16-, 20- and 28-pin), together
with the optimized peripheral sets, and the
powerful HC08 CPU, make this an ideal
low-end controller.
Cost-Effective LIN Family
Features
• Embedded, fully automotive flash
• Range of memory from 4 KB to 16 KB
• 10K write/erase cycles at -40°C to +125°C
Benefits
• Qualified for high temperatures, shock,
vibrations and humidity as required by the
automotive industry
• Cost-reduction path for high-volume stable
programs
• Reduced production programming costs through
ultra-fast programming at operating voltage
• Helps protect code from unauthorized reading
and to guard against unintentional writing/
erasing of user-programmable segments of code
• Allows real-time flash updates
• Eliminates the cost of all external clock
components
• Helps to reduce board space
• Eliminates or reduces EMI generated from
external clocks
• Allows option of external RC and external crystal
• Full-duplex operation allows simultaneous
transmission and reception of data
• ESCI arbiter allows measurement of LIN
synchronization data without separate timer
hardware
• Finely adjustable baud rate prescalers allow
extremely precise control of baud rate
• Enhanced detection of LIN break symbols to
prevent false interrupts
• ESCI arbiter allows measurement of LIN
synchronization data without separate timer
hardware
• Finely adjustable baud rate prescalers allow
extremely precise control of baud rate
• Enhanced detection of LIN break symbols to
prevent false interrupts
Second-Generation Flash or Cost-Effective ROM Memory Options
• Ultra-fast programming: 64 bytes in 2 ms
• Flash block protection
• Flash reprogrammable in circuit
Internal Clock Oscillator
• 1 MHz, 2 MHz and 3.2 MHz nominal bus
frequencies
• Fully trimmable internal oscillator
• Less than 0.4 percent oscillator accuracy within
a LIN frame
Typical Applications of the QC Family
An application focus area of the QC family
is the LIN. LIN is a UART-based, single-
master, multiple-slave networking architecture
originally developed for automotive sensor
and actuator networking applications.

Periodic Wake-Up Module
• Selectable timeout periods (40 µs to three
minutes)
• Exit from low-power stop mode without external
signals
• Dedicated low-power 32 kHz internal oscillator
separate from the main system clock sources
• Accessible in all modes of operation (run,
wait and stop)
• Full-duplex operation allows simultaneous
transmission and reception of data
