Renesas RX140 microcontrollers double the performance of their predecessors

Published

on

Renesas Electronics has unveiled the RX140 32-bit ultra-low power microcontroller group that complements the entry-level RX100 series. The RX140 microcontrollers, built on the powerful Renesas RXv2 processor core, clocked at up to 48 MHz, perform 204 points in the CoreMark test, which is about twice the result of the RX130 group of microcontrollers. Also, the RX140 microcontrollers are more than 30% more energy efficient than their predecessors. Their current consumption is 56 μA / MHz in active mode and only 0.25 μA in standby mode. The new microcontrollers are designed for home appliances and industrial applications.

The RX140’s strengths include the latest capacitive touch input blocks to deliver an enhanced user experience. They meet the immunity requirements for touch input as outlined in IEC EN61000-4-3 and EN61000-4-6. Built-in multi-scan function and automatic input recognition allows for increased sensitivity by simultaneously measuring with multiple electrodes. This allows automatic touch detection even in standby mode, making it easy to design interfaces with touchless or proximity functions.

The manufacturer also notes expanded peripheral equipment. For example, the number of I / O ports has been increased and support for the CAN bus has been added. Built-in AES encryption accelerator and True Random Number Generator (TRNG) reduce the risks of security threats such as data leakage or manipulation.

At the pin level, the RX140 microcontrollers are compatible with the RX130, making it easy for designers and manufacturers to implement.

At the same time, the Target Board is presented, which makes it easier to familiarize yourself with the RX140 microcontrollers and evaluate them.

The RX140 microcontroller group includes 64 KB flash models in 32 to 64 pin packages. Additional configurations and larger memory models (over 128 KB) should begin mass production in February 2022. As a price reference, the manufacturer reports that the R5F51403ADFM # 30 in a 64-lead LFQFP package with 64KB of flash is priced at $ 1.02 apiece for 10,000 orders.

In the fall Roscosmos will launch a Soyuz 21b rocket

The first rocket completely on a new type of fuel – naphthyl – will be launched from the Vostochny cosmodrome in the fall. The Gonets-M and Skif-D satellites will go into orbit on it. Ruslan Mukhamedzhanov, General Director of the Center for the Operation of Ground-Based Space Infrastructure (TsENKI, part of Roscosmos), spoke about this at the Army-2022 forum.

In the fall, Roscosmos will launch a Soyuz 2.1b rocket on a new type of fuel - naphthyl

The first launch on naphthyl from the Vostochny Cosmodrome is planned for this fall“, he said.

According to Mukhamedzhanov, it will be the launch of the Soyuz 2.1b carrier rocket with three Gonets-M communication satellites and the Skif-D demonstration satellite for broadband Internet access, which will be the first device under the Sphere federal project.

The Director General of TsENKI recalled that work on the transfer of the Soyuz launch complex to naphthyl at the Vostochny cosmodrome was carried out in several stages. First, the necessary technological equipment was installed, then last fall, specialists from the Vostochny Space Center and the Research Institute of Launch Complexes named after V.P. Barmin (TsENKI branches) connected it to the operating systems.

Autonomous tests, the CEO noted, were completed in December last year. In particular, naphthyl filling systems and an automatic process equipment control system were tested. “To complete the full transition cycle, it is necessary to conduct comprehensive tests that take place directly during the preparation of the launch vehicle for launch, when it is installed in the launch system”, Mukhamedzhanov added.

SpaceX will pay to hack the Starlink network

SpaceX will pay to hack the Starlink network

SpaceX has said anyone can hack into its Starlink satellite network and is willing to pay them up to $25,000 to find specific vulnerabilities. The announcement came after cybersecurity expert Lennert Wouters revealed that he successfully hacked a Starlink terminal using a $25 chip. Wouters said his attack could render Starlink terminals unusable and allow arbitrary code to run on them.

SpaceX, in turn, congratulated Wouters on his successful hacking attempt in a six-page document entitled “Starlink Welcomes Security Researchers (Find Bugs)”. “We find the attack technically impressive, and this is the first such attack that we are aware of on our system,” the document says. However, the hack carried out by Wouters using a homemade chip should not worry Starlink users, as it will not have a direct impact on the satellites, SpaceX added.

In-house engineers are always trying to hack Starlink to improve service and make the network more secure, according to a SpaceX document. Security researchers can conduct their own testing, and if they discover a vulnerability and report it, they can receive a monetary reward, the company notes. The award ranges from $100 to $25,000. But SpaceX has conditions: bug hunting must not disrupt user services, physical attacks on large-scale infrastructure are prohibited, as well as email spoofing (forgery of the sender’s address in emails).

Brazil wants to tokenize gold and use blockchain

Member of the Brazilian Chamber of Deputies Joenia Wapichana proposed to tokenize gold and use blockchain to prevent illegal mining and sale of this precious metal.

Brazil wants to tokenize gold and use blockchain

According to Vapichana, the country should be able to account for gold mining activities on its territory. The bill introduces new legislation aimed at transactions with precious metals and their transportation.

The bill will also help fight illegal mining activities in the country.

The legislator noted that about half of the gold in the country is mined illegally. She added that illegal mining activities have worsened the environmental impact of the mining industry.

These operations are accompanied by mercury pollution, violence and deforestation, which has been frequently reported in the national and international press, as well as civil society organizations that fight to protect the forest and guarantee the rights of indigenous peoples.

Therefore, Vapishana proposed to create a single system based on the blockchain, in which information about the mined gold will be entered, and through which its sale will be carried out. To do this, it is necessary to make the necessary amendments to the legislation of the country, the deputy added.

The idea of ​​tokenizing natural resources also came up this summer with the government of the Central African Republic (CAR). It believes that this will attract funds from foreign investors and accelerate the adoption of crypto assets in the country. In 2020, Circle CEO Jeremy Allaire suggested that within a few years, asset tokenization will gain popularity as it is an effective way to increase liquidity.
