AUSTIN, Texas -- April 3, 2014

Continuing to expand one of the industry’s broadest portfolios of ARM-based
microcontrollers (MCUs), Freescale Semiconductor (NYSE: FSL) introduces the
lead families of the new Kinetis V series, optimized for motor control and
digital power conversion applications. To complement the Kinetis V series,
Freescale also introduces the Kinetis Motor Suite, a bundled enablement tool
that helps to maximize motor efficiency while reducing development cost and
time to market.

Modern sensored and sensorless motor control is demanding on the MCU and
requires precise speed and position measurement in parallel with general
application task processing. The MCU must be able to support a range of
control algorithms – from entry level BLDC to advanced PMSM and ACIM control
loops – as well as offer high speed/resolution ADCs and PWMs for fast,
accurate signal capture and response. Developers must also have access to
intuitive software tools that allow them to create, tune and implement their
control algorithms quickly and efficiently.

The Kinetis V series’ fast signal acquisition and processing capabilities,
combined with the intuitive Kinetis Motor Suite, provide a unified hardware
and software platform for developing scalable, cost-effective motor control
systems. With the Kinetis V series, designers of products ranging from low-end
pool pumps to advanced robotics can now leverage the increased efficiency,
quieter operation, and improved reliability benefits of the latest motor
technologies.

“With Freescale’s more than 20 years of motor control processor expertise, and
our exceptionally strong reputation in these markets, motor control and
digital power were the logical next steps for the Kinetis roadmap,” saidGeoff
Lees, senior vice president and general manager for Freescale’s
Microcontroller business. “Kinetis V series’ excellent price/performance
ratio, tailored peripheral set and bundled Kinetis Motor Suite allow
developers to create highly efficient designs faster and easier than ever
before.”

Kinetis V series MCUs and the new Kinetis Motor Suite software will be on
display during the Freescale Technology Forum (FTF) Americas from April 8-11
in Dallas, Texas.

Kinetis KV4x, KV3x and KV1x MCUs

The KV4x family is the flagship of the existing V series, targeting digital
power conversion designs, as well as PMSM and ACIM applications requiring high
dynamic control. Engineered for optimal performance, KV4x MCUs incorporate a
150 MHz ARM Cortex-M4 processor with floating-point unit executing from up to
256 KB of Flash memory via a 128-bit wide interface that minimizes CPU wait
states. With up to 30 timer channels – twelve provided by the highly flexible
eFlexPWM – KV4x family devices provide multiple three-phase motor drive
capabilities supporting dead time insertion, complementary pairing of PWMs,
half cycle reload and fault detection. For sensorless motor control
speed/position detection, two 12-bit ADCs support sample rates of up to 1.9
Msps and can be triggered by any module connected to the MCU’s internal
peripheral crossbar, including timers, analog comparators or GPIO. For
switched mode power supply applications, an eFlexPWM module provides 300
picosecond resolution, while the ADCs sample at 4.1Msps. This improves
real-time control, ensuring that critical timing windows for data gathering
and system updates are met. In addition, the KV4x family’s high degree of
feature integration enables up to 30 PWM outputs, 38 ADC channel inputs, as
well as CAN, UART and SPI interfaces to be housed in a 100-pin LQFP package.

The KV3x family, also Cortex-M4 based, targets intermediate PMSM applications
with CPU frequencies of 100-120 MHz, up to 512/96 KB of Flash/SRAM and an
optional external bus interface for off-chip system expansion.

The KV1x family represents the entry-level of the series and integrates the
industry’s fastest Cortex-M0+ MCU core. With a CPU frequency of 75 MHz, plus
hardware divide and square root block, KV1x devices offer a performance
increase of more than 25 percent in math-intensive applications compared to
other MCUs in the family’s class. Packing this high processing efficiency into
a small, 32 KB solution positions KV1x MCUs as cost-effective options for BLDC
and PMSM designs that currently rely on larger, more expensive 32-bit MCUs.

Kinetis Motor Suite and additional motor control enablement

Traditionally, PID loop tuning is trial and error based, requires in-depth
motor control expertise and results in non-optimal system performance that can
degrade over time. Kinetis Motor Suite addresses these issues, simplifying the
development cycle, delivering more predictable system response and reducing
time to market.

The Kinetis Motor Suite consists of three software components for tuning,
observing and managing motor control system operation: the Kinetis Motor
Tuner, a GUI for motor parameter configuration that enables fast, precise PID
loop tuning in minutes rather than months; Kinetis Motor Observer, advanced
software pre-programmed into the MCU that enables tuning of control loops and
estimation blocks to regulate motor and inverter efficiency, power factor,
current/torque ripple and noise, and; the Kinetis Motor Manager, which
provides a real-time, non-intrusive display of system variables and the MCU
memory map. The motor manager includes a software oscilloscope with debugging
and data logging capability. Kinetis V series MCUs pre-programmed with Kinetis
Motor Suite software will be available to order in the third quarter of 2014.

Freescale also provides a range of GUI-based motor configuration and debug
tools, software libraries and Tower System development modules.

Availability

Production-qualified Kinetis KV1x MCUs are now available with suggested resale
pricing from $0.99 (USD) in 10k unit quantities. Kinetis KV3x MCUs are
currently sampling, and Kinetis KV4x MCUs are planned to sample in Q3 2014.
