increasing demands for Ethernet connectivity
in consumer and industrial applications, the
family features advanced power management
and sophisticated Quality of Service (QoS)
capabilities. Pricing and
samples are available
upon inquiry with volume
production starting in Q1,
2011.
Micrel’s new switch family
directly addresses these
needs coupled with
energy eciency enabling
compliance to important
green standards such as
ENERGY STAR. The exible
congurability of the family
allows the requirements of a
variety of applications to be
satised based on a single
foundation system platform.
Sophisticated QoS features such as tag and
port-based VLAN support and IPv6 priority
classication make these devices ideal for
today’s most demanding IP content based
applications in the digital home; IPTV, IP-STB

Micrel launched the KSZ8895/8875/8864
series. The devices are low-power, highly
integrated, 4/5-port Layer-2 switch-on-a-
chip ICs. Leveraging Micrel’s latest green
physical transceiver and switch technology,
the product family achieves a 50 percent
reduction in power consumption compared
to the previous generation. Meeting the

Automotive-microcontroller family delivers maximum safety and
value
Qorivva 32-bit microcontrollers from
Freescale Semiconductor drive Power
ArchitectureR in-car computing, oering
engineers lower development costs, faster
time to market and zero-defect capability
for engine, safety and body applications.
All devices are based on Freescale’s scalable
e200 processor core, with single-issue or twin
issue congurations providing a wide range of
performance options. Designers can also take
advantage of the single instruction set and
common peripherals to lower development
costs and accelerate time to market.
The Qorivva MPC55xx and MPC56xx families
provide variants featured for specic
application areas. Devices for use in body
and security systems prioritise low power
consumption for “always-on” systems, and
support advanced connectivity standards such
as LIN, CAN, MOST, FlexRay™ and Ethernet.
There is also encryption for advanced vehicle-
network security.
MCUs for safety and chassis applications
feature a safe computational shell providing
a market-standard safety architecture for
braking, steering and radar-based systems. The
safety architecture includes redundant cores
with fault monitoring and event recording as
well as correction systems ensuring maximum
protection.
Where high sensing and computing
capabilities are required, such as in hybrid
vehicles and power-train-control applications,
multi-core processors and advanced motor-
control peripherals are combined with
high-precision analogue interfaces and
digital communications links to analogue
sensors. A knock interface is integrated for
powertrain-control applications, bringing
a function traditionally implemented in a
custom ASIC onto the chip to further reduce
development costs. Many Qorivva powertrain
MCUs will also feature Freescale’s advanced
safety architecture. There is also an extensive
development ecosystem, including Freescale
CodeWarrior and third-party tools as well as
software enablement packages including a
motorcontrol library, powertrain and engine
functions, AUTOSAR MCAL driver suites and an
AUTOSAR RTOS for single-core and multi-core
MCUs.
and Micrel’s signature high reliability and
quality also make these devices suitable for
connectivity applications in the fast growing
industrial automation and automotive
markets.
The devices support a single 3.3V power
supply with an internal 1.2V LDO, with options
for 3.3V, 2.5V or 1.8V IO voltages. Further power
savings are supported by advanced power
management, including the device’s “Energy
Detect Power Down” mode. This mode is
activated when the cable is unplugged, and
the “slow oscillator” mode is activated when
the device is not in use.
The product family provides exible host
processor and PHY interfacing via MII or RMII.
Flexibility is also provided in terms of copper
or ber media interfaces. On-chip termination,
and internal generation of the 50MHz RMII
clock further reduces bill of materials cost and
enables a small package size (64-pin QFN for
KSZ8864RMN).
