miths Interconnect has been enlisted by Mitsubishi Electric
Corporation to jointly develop a G- band satellite for the Japan Aerospace Exploration Agency
cycle (GOSAT-GW). These microwave radiation
measurements will assist in preventing disasters attributed to global warming and climate
change, and to advance scientific and technological methods that enable more accurate prediction of climate change. The fully integrated antenna and receiver is an integral part of the system which will provide the frequency and the bandwidth that the GOSAT-GW mission requires. Among very few companies with
both millimetre wave component and subsystem expertise combined with a background in both space applications and antenna system design, Smiths Interconnect is well positioned to provide technical support and a reliable, lightweight, and compact system solution.

FASTER DEBUGGING
Percepio and Lauterbach are aiming to achieve faster debugging through closer integration between Percepio Tracealyzer and Lauterbach’s series of TRACE32 tracing tools. Lauterbach users will be able to use
RENESAS RELEASES 16-BIT GENERAL-PURPOSE RL78/G23
Renesas Electronics Corporation has started mass production of its 16-bit general- purpose RL78/G23 microcontroller (MCU). Compatible with its current general- purpose RL78 MCUs, such as the RL78/G13, the RL78/G23 increases the on-chip flash memory capacity to 768KB and substantially expands on-chip peripheral functions. By adopting a new process, the
RL78/G23 realises 44µA/MHz at CPU operation and 210nA during STOP (with
4KB of SRAM retention), an even lower power consumption compared to current RL78 MCUs. In addition, the newly implemented SNOOZE mode sequencer (SMS) makes it unnecessary to activate the CPU while any peripheral operations are operating in snooze mode, reducing power consumption for applications that utilise intermittent operation. Furthermore, the logic and event link controller (ELCL) adds logic functionality to the capabilities of a conventional event link controller (ELC). /

Arm Cortex-M microprocessors to live stream software trace data into Percepio Tracealyser, providing visual trace diagnostics for accelerated debugging and verification. The solution is described in a recent application note from Percepio and leverages the Percepio trace recorder library, supporting e.g. FreeRTOS and SAFERTOS. Lauterbach’s integration allows
Tracealyzer users to record runtime data at unprecedented speeds using the Lauterbach µTrace for Arm Cortex-M,” said Johan Kraft, CEO, Percepio. “The next step is to leverage hardware trace data in Tracealyzer to show more detailed information. We have a working solution in development, and we have been collaborating with Lauterbach on that for some time.” Ultimately, the goal is to enable all
Lauterbach customers to use visual trace diagnostics with Percepio Tracealyzer based on hardware trace data. The two companies have joint customers asking for this capability and will be announcing further products.

POWER FACTOR CORRECTION IC DELIVERS 98% FULL-LOAD EFFICIENCY
Power Integrations’ HiperPFS-4 power factor correction (PFC) controller IC now comes with an integrated Qspeed low reverse recovery charge (Qrr) boost diode. Resulting in more than 98% full-load efficiency in PC, TV, and similar applications between 75W and 400W. The HiperPFS-4 IC combines continuous conduction mode (CCM) PFC
control circuitry, the boost diode and a 600V MOSFET in one device. Including the boost diode reduces heatsink mounting, leading to a simpler design and better thermal performance. Furthermore, the built-in Qspeed diode also provides greater robustness against AC line surges since parasitic trace inductances are minimised, which in turn reduces voltage spikes seen by the power switch during transients by up to 50V. The integrated 600V MOSFET is therefore easily able to meet the 80% de-rating requirement when delivering a 385 VDC constant-voltage bus. HiperPFS-4 ICs achieve a power factor of greater than 0.95 at above 20%
load. The Qspeed boost diode is optimised for continuous conduction mode PFC operation featuring very low reverse recovery losses that approach the performance of silicon carbide devices without the financial penalty.
