In choosing to put RISC-V cores on its new microcontroller – fear not, there are Arm Coretex-M33 cores too – Raspberry Pi will be helping put this architecture on the map. Proc0 and Proc1 can independently be set to be an Arm Cortex-M33 or a RISC-V core at boot Not that RISC-V is not already climbing rapidly in the instruction ...
Raspberry Pi’s RP2350, its second-generation microcontroller, will be available by the end of the year in flash-less and flash-inclusive forms, in two packages: RP2350A QFN60 no flash $0.80 RP2350B QFN80 no flash $0.90 RP2354A QFN60 2Mbyte flash $1.00 RP2354B QFN80 2Mbyte flash $1.10 QFN60 types are 7 x 7mm and have 30 GPIOs, QFN80 types are 10 x 10mm and ...
Raspberry Pi has announced its second microcontroller, the RP2350, adding two RISC-V cores alongside improved Arm cores, more ram, and security. Not initially available on its own (ETA pre-year-end), it will first ship as part of the Raspberry Pi Pico 2 single-board microcontroller (right) – which is the same 21 x 51mm size as the original Pico, and priced from ...
Nature provides the model for integrating sensors for a distributed edge AI system, say Bartosz Boryna and Zuzana Jirankova. The horseshoe crab (limulus polyphemus) is recognised by scientists as an interesting model for vision research because the animal’s body is large enough to study and its retina neurons are quite easily accessible. The crab has several compound eyes distributed over ...
Rohm has released a line of 16bit microcontrollers for power supplies with hybrid analogue-digital control loops, plus an evaluation board with software as a design stepping stone. “In recent years medium power power supplies are required to provide a level of reliability and precise control that is difficult to meet with analogue-only configurations,” said Rohm. “On the other hand, while ...
Alif Semiconductor has removed the Bluetooth transceiver from its Balletto B1 microcontroller to create an MCU with (or without) 46Gop/s of neural network processing that will be available in packages as small as a 3.9 x 3.9mm 90bump WLCSP. Dubbed E1C, the family all get a single 160MHz Arm Cortex-M55 CPU with Helium vector processing extensions, then some will also ...
Segger has introduced microcontroller security feature configuration to its in-circuit programmers, debug probes and trace probes. “Modern chips require an increasing level of customer and device-specific configuration,” according to the company. “The driving force is security, especially as more and more devices connect to the Internet. Unfortunately, there is no industry standard for provisioning device security and configuration. Options differ ...
SiPearl has revealed some details of its AI microprocessor. Rhea1, as it will be called, “will fulfill the mission entrusted by EuroHPC JU and the European Processor Initiative consortium: to bring dedicated high-performance microprocessor technologies back to Europe”, according to the company. The plan is for it to have 80 Arm Neoverse V1 cores, each with two 256bit SVEs (scalable vector ...
Infineon has introduced microcontrollers for monitoring vehicle Pb-acid batteries, that can be powered directly from the battery and include a pair of high-accuracy ADCs. Operation is over 3.6 to 28V, with reduced function up to 42V, and the drvices have been developed with functional safety in mind. “The device is developed compliant to ISO 26262, meeting all process requirements for ...
Microchip has announced its most secure 32bit microcontrollers – a series of 120MHz Cortex-M33 MCUs for connected things. “Emerging requirements make security mandatory for the majority of IoT connected devices,” said Micrchip v-p Rod Drake, claiming: “The PIC32CK makes it cost effective to provide hardware-based security to mid-range microcontroller applications.” That said, security does not come with every PIC32CK MCU ...
