Silicon Labs C8051F97x capacitive sense MCUs in stock at Mouser

TAIWAN: Mouser Electronics Inc. is now stocking the C8051F97x low-power capacitive sense microcontrollers from Silicon Labs.

Boasting a sleep current as low as 55nA, the new C8051F97x microcontroller (MCU) family is based on a high-speed pipelined 8051 core that is enhanced with the addition of a single-cycle 16x16 Multiply Accumulate (MAC) unit.

The C8051F97x family targets touch user interfaces with its capacitive sense interface, allowing the detection of virtual buttons, sliders, and wheels as well as proximity sensing.

The Silicon Labs 8051F97x Low-Power Capacitive Sense Microcontrollers, available from Mouser Electronics, are fully integrated mixed‑signal microcontrollers. The devices include up to 32KBytes of Flash that is programmable in 512Byte sectors, and up to 8.25KBytes RAM.

A 10‑bit analog to digital converter (ADC) can capture signals up to 300ksps. The chips can operate with a 1.8V to 3.6V supply voltage and have seven power modes: In Active Mode, the device draws only 200µA/MHz. In the lowest power mode, Sleep Mode, the microcontroller draws as little as 55nA and can wake up on an oscillator failure, SmarRTClock timer event, or on an I2C address match.

The capacitive sense unit uses a capacitive‑to‑digital circuit to determine the capacitance present on a port pin. An internal analog multiplexor allows the unit to take measurements from different port pins. The unit can be configured to take capacitance measurements from one port pin or a group of ports pins.

A selectable gain circuit allows the developer to adjust the maximum allowable capacitance. A 22‑bit accumulator is built into the capacitance sense unit, which can be configured to average multiple conversations from a single input pin.

For security applications, each microcontroller contains a 128‑bit unique key to specifically identify each device. The C8051F97x MCUs boast an on-chip debugging interface that provides non‑intrusive, full-speed, in‑circuit debugging of the microcontroller while operational. The debugging interface uses no on‑chip resources and does not interfere with running code.

The C8051F970 Development Kit, also available from Mouser Electronics, provides a complete evaluation and development platform for C8051F97x microcontrollers. The board supports capacitive sensing applications and contains all the hardware and software needed to begin developing projects using the C8051F970 microcontroller.

TRINAMIC motor drivers at work

HAMBURG, GERMANY: —TRINAMIC Motion Control, a leading global developer of motor and motion control technologies, revealed its patent-pending technology for stepper motors. Dubbed stealthChop, the new technology significantly reduces the noise of conventional stepper motor operation.

Motors operating at low speed exhibit a phenomenon known as magnetostriction, which causes an audible low frequency ‘hum.’ This low-frequency noise is well known as the 60Hz hum that emanates from transmission lines and transformers. Trinamic’s stealthChop minimizes magnetostriction by implementing a PWM algorithm that relies predominantly on voltage modulation for motor control at lower speeds. This technology minimizes PWM current fluctuation, which is the primary cause of low-speed hum.

“Stepper motors used in automation must respect the needs of their human overlords. The continuous noise of individual stepper motors in a laboratory environment may be rather distracting, and the din from hundreds of stepper motors in an industrial implementation can be deafening,” explained TRINAMIC R & D chief, Dr. Stephan Kubisch.

“Our customers asked Trinamic to perfect a commutation scheme for lower step frequencies that reduces noise. We made it self tuning, easy to use and added an automated switch to transition to higher frequencies.“

Noise limitations are especially desirable in applications that normally occur in close proximity to human operators, in applications where multiple stepper motors are in use, in video surveillance applications where installations near walls and ceilings amplify noise, and in consumer applications, like home automation and air conditioning, where users expect minimal noise.

FCI intros BarKlip cable I/O

SINGAPORE: FCI, a leading supplier of connectors and interconnect systems, announced the release of the BarKlip I/O Power Connector.

The BarKlip I/O connector, rated for up to 200Amps/contact per UL & CSA criteria, offers improved electrical performance and long-term reliability compared with alternative designs.

The connector is designed to connect with a system rack bar to achieve a direct pluggable connection to an uninsulated busbar. The connection generates low energy loss with a maximum resistance of only 0.2mOhms per contact.

The BarKlip I/O Connector features 14 fully independent cantilevered beams, which provide a true compliant spring to adjust for variations in busbar alignment and surface finish. In addition, the BarKlip I/O connector is a floating panel mount design.  An installed height of <34mm 1u="" and="" architectures.="" commonly="" computing="" datacenters="" enables="" equipment="" found="" hyperscale="" in="" nbsp="" new="" p="" rack-mounted="" their="" use="">
The available wire range is 14AWG to 2AWG, allowing users to define the wire gauge and length flexibly in terms of actual requirement. The BarKlip I/O Connector is designed to operate between -40°C and 125°C.

“The BarKlip I/O Connector provides a convenient, low voltage loss and highly reliable method to connect to many of FCI’s busbar power distribution solutions” says Michael Blanchfield, Portfolio director for Power Solutions at FCI.

“FCI’s proprietary plating technology adds an additional benefit to customers by providing maximum conductivity and longer-term reliability without concerns for corrosion. We are confident the BarKlip products will meet many of our customers’ demands for high reliability in direct connect busbar applications.”

Ideal Power intros 125kW power converter family

AUSTIN, USA: Ideal Power Inc. announced its 125kW converter family, including a three-port hybrid converter and two-port battery converter.

Utilizing the same award-winning technology as its 30kW hybrid converter, the 125kW converter products are expected to lower costs and improve efficiency for integrating photovoltaic (PV) and energy storage solutions up to megawatt scale, as well as provide off grid and grid resilient (grid-tied battery backup) capabilities.

Ideal Power also announced that it has received an initial order for its 125kW hybrid converter from CODA Energy, a California based manufacturer and installer of commercial and industrial energy storage products. Ideal Power will display its new 125kW hybrid converter at the Solar Power International Conference, booth #2658, in Las Vegas on October 20 - 23, 2014.

"The mutual benefits of deploying battery storage with PV are well known 'off-grid,'" stated Peter Nortman, COO, CODA Energy.

"The argument to deploy storage with PV 'on-grid' is perhaps even more compelling to a resilient and sustainable energy future. We expect Ideal Power's 3-port hybrid architecture to help us meet our customer's needs in this important market space due to its comprehensive feature set and compact, efficient design."

According to information, insight and analytics firm IHS, commercial grid-tied battery inverters co-sited with PV is forecasted to grow from 36 MW of global installations in 2014 to 643 MW by 2018 and the off grid micro-grid battery inverters co-sited with PV market is forecasted to grow from 34 MW of global installations in 2014 to 400 MW by 2018.
