Easy-to-Use Evaluation Kit Combines Hardware and Development Tools
for System Manufacturers Developing Blood Pressure Monitor Applications

TOKYO–(BUSINESS WIRE)–Renesas Electronics Corporation (TSE: 6723), a premier supplier of
advanced semiconductor solutions, today announced an expansion of its
healthcare solution lineup with the launch of a new blood pressure
monitoring evaluation kit. The new blood
pressure monitoring evaluation kit
comprises hardware and software
elements needed to jump start blood pressure measurement design. The kit
includes a pressure sensor, arm cuff, pump, electronically controlled
valve, LCD panel, and a reference board that incorporates an RL78
Microcontroller (MCU)-based ASSP (application specific standard product)
that includes analog functions required for blood pressure measurement.
Reference software and graphical user interface (GUI) development tools
are also part of the new evaluation kit. Using the new evaluation kit,
system manufacturers can immediately begin their system evaluations and
significantly reduce their development time.


The Internet of Things offers consumers connected tools with which to
manage their personal healthcare more efficiently. For instance, blood
pressure monitors are already popular personal medical devices and the
market is expected to grow further as blood pressure monitoring
functions are incorporated into wearable devices. The growth of this
market offers new business opportunities, but can also be challenging,
particularly for system manufacturers who are new to the connected
healthcare device ecosystem and may not have the built-in
application-specific expertise. Blood pressure measurement requires a
specific expertise, including filtering functions for extracting the
waveforms required for measurement, making it extremely time consuming
to start studying this area from the very beginning.

Renesas has developed the new blood pressure monitoring evaluation kit
to alleviate the development pain points, providing functions close to
those used in actual blood pressure monitors thus accelerating blood
pressure measurement system development.

Key features of the blood pressure monitoring evaluation kit

  • One-stop solution that enables immediate
    evaluation at the system level

    The new blood pressure
    monitoring evaluation kit comprises hardware and software elements
    needed to jump start blood pressure measurement design, including:

    -A
    full range of hardware components, including a pressure sensor, arm
    cuff, pump, electronically controlled valve, LCD panel, and a
    reference board that incorporates the newly-developed RL78/H1D
    ASSP with the analog functions required for blood pressure measurement.

    -Reference
    software that provides the algorithms required for blood pressure
    measurement and that can be easily modified, as well as access to
    smartphone applications, and a graphical user interface (GUI) tool.

    -A
    Bluetooth Low Energy (BLE) module, which enables the measured data to
    be transmitted to a smartphone under the Continua standard blood
    pressure monitoring (BPM) profile is also provided in the new
    evaluation kit.

  • Development support with GUI tool,
    specialized for blood pressure measurement

    -The
    pressure sensor, pump, electronically controlled valve components, and
    pulse width modulation control can be set from the GUI tool. If the
    system structure is the same, the GUI tool can also be used for system
    evaluation of the actual application the system manufacturer is
    developing.

    -The IIR digital filter calculations required
    for extracting the pulse waveform from the cuff pressure output
    waveform during blood pressure measurement can also be simulated using
    the GUI tool. The digital filter constants calculated based on this
    simulation can be written from the GUI tool to the RL78/H1D firmware
    and verified in the actual application being developed. This
    significantly reduces the number of steps in the development process.

  • RL78/H1D ASSP with optimized analog functions
    for healthcare applications

    -The RL78/H1D is a new
    ASSP of the RL78 Family of MCU. The RL78/H1D is designed to control
    systems required for blood pressure measurement with a single chip. It
    incorporates rich analog functions including high-resolution delta
    sigma A/D converters, programmable gain instrumentation amplifiers,
    D/A converters, operational amplifiers, and other circuits required
    for blood pressure measurement, as well as timers for PWM (pulse-width
    modulation) control.

    -In addition to the delta sigma 24-bit
    A/D converters, the RL78/H1D also provides 10-bit sequential
    comparison A/D converters that operate asynchronously. This simplifies
    implementation of systems providing temperature measurement and
    battery voltage monitoring while measuring the blood pressure.

    -The
    Rich analog functions make the new ASSP ideal not only for blood
    pressure monitoring systems but also for a wide array healthcare
    application including biosensors.

    -Samples of the RL78/H1D
    ASSP are available now. Pricing varies depending on the memory
    capacity, package and number of pins. For example, the R5F11NMG 80-pin
    LQFP package type with 128 KB flash ROM capacity is priced at US$3.50.
    The R5F11NMG includes an LCD controller for arm- and wrist-type blood
    pressure monitors, and a 4mm x 4mm miniature ball grid array (BGA)
    package for use in wearable devices. (Pricing and availability are
    subject to change without notice.)

Renesas plans to expand its range of solutions for the healthcare field
and will continue to contribute to the realization of a safe and secure
smart society, including the development of smart connected devices for
the industrial and healthcare industries.

Pricing and availability

The new blood pressure monitoring evaluation kit can be ordered now
priced at US$600.00 per unit. (Pricing and availability are subject to
change without notice.)

(Note) The blood pressure monitoring evaluation kit cannot be used as
medical equipment.
