Microchip is aiming at automotive single-pair Ethernet links up to 40m long with a 7 x 7mm transceiver ICs called LAN8870B. Single-pair Ethernet is also being used in avionics, robotics and automation, it said. “For interoperability across industries, LAN887x PHYs are designed to be compliant with IEEE 802.3bp for the 1000BASE-T1 specification, and IEEE 802bw-2015 for the 100BASE-T1 specification*,” according ...

A 2Gbyte Raspberry Pi 5 has been launched, priced at $50 compared with $60 for the 4Gbyte version. As well as reduced memory size, cost-saving comes from changing the main processor IC. 4 and 8Gbyte models have the 16nm Broadcom BCM2712C1, which has quad 2.4GHz Arm Cortex-A76 cores. “Alongside the features required to power a Raspberry Pi, it also contains ...

Richardson RFPD, an Arrow Electronics company, has announced  a featured lineup of Ka-band, GaN-on-SiC MMIC power amplifiers from United Monolithic Semiconductors. Offered in die and plastic QFN packaging, the devices are available in a variety of power levels to support Ka-band SATCOM uplink and 5G FR2 bands n257, n258, n259 (partial), n260 and n261. UMS’ proprietary GH15 GaN process is ...

Farnell is now shipping the new high-power SPDT (Single-Pole Double-Throw) RF antenna switch from Toshiba. The SPDT RF (TCWA1225G) switch is important for the expansion of 5G networks. This is because the expansion requires antennae that are increasingly composed of complex signal transmission paths that need RF switching with low insertion loss and high input power, but in a compact ...

Microchip Technology has added the three more ICs to its TrustFlex secure key provisioning service. Secure key provisioning is putting secret information into ICs at a protected facility. Aimed at companies that do not want to handle their own provisioning, TrustFlex is Microchip’s mid-tier secure provisioning service, for 2,000 units and upwards. The most flexible tier starts at 4,000 units, and ...

Toshiba has just released a 700MHz to 5GHz single-pole, double-throw antenna switch in a 1.9 x 1.9mm WCSP package. “TCWA1225G offers an input peak power of 46dBm – at 8dB PAR,” the company said. “This has been achieved by adopting Toshiba’s original CMOS process and optimising the internal switching circuitry.” The process also reduces insertion loss, typically to 0.6dB at ...

SemiQ has put 1,200V silicon carbide mosfet and Schottky diode half-bridges into standard ’62mm’ industrial power modules. There are four parts, each measuring 62 x 106.5 x 17mm (plus terminals): two mosfet hald-bridges and two Schottky half-bridges, aimed at new designs as well as efficiency-boosting replacements in legacy systems. 1.2kV 62mm power modules  Configuration Current Rds(on) GCMX003A120S7B1 SiC mosfet half-bridge ...

Richardson RFPD is stocking 0402 (1005 metric) glass sandwich resistors designed to work from dc to 40GHz. Made by Kyocera AVX, and called the UBR series, they measure 1 x 0.5 x 0.5mm and have a flexible termination. “‘Flexiterm’ is a surface-mountable, automotive-qualified termination that adds an extra margin of protection against damage due to flexure during installation,” according to ...

Bourns is offering IEC-grade surge protection for ac or dc power rails with four DIN rail mount device series. 1270 series AC surge protection to IEC/EN 61643-11 Class I + Class II / T1+T2 1280 series the same, plus a thermal disconnector “that eliminates the need for up-stream over-current protection”, said Bourns. 1430 series DC surge protection to IEC/EN 61643-31 ...

SiFive has announced RISC-V core intellectual property for data centre processors. Called P870-D, it is an update of the non-data centre P870, with support added for AMBA CHI protocol. “By harnessing a standard CHI bus,” said SiFive, “the P870-D enables SiFive’s customers to scale up to 256 cores while harnessing industry-standard protocols including CXL [Compute Express Link] and CHI C2C [chip ...
