u-blox ALMA-B1 and NORA-B2, Bluetooth 5.4 LE modules are based on Nordic nRF54H20 and nRF54L15 SoCs

Wireless communication solutions provider, u-blox has added two new modules to its Bluetooth LE portfolio with the ALMA-B1 and NORA-B2 modules built upon the latest low-power wireless nRF54 chips from Nordic Semiconductor. Both modules come in a portable, power-efficient layout and support Bluetooth 5.4 and 802.15.4 (Thread, Matter, Zigbee). The ALMA-B1 and NORA-B2 BLE modules are powered by the low-power nRF54H20 and nRF54L15 SoCs, respectively. This enables them to provide IoT devices with sufficient processing power for edge computing and machine learning without the need for external components. u-blox claims that the ALMA-B1 module provides “more than twice the processing power of previous Bluetooth LE modules” and can replace general-purpose microcontrollers in compact solutions. Also, the NORA-B2 reportedly “consumes up to 50% less current compared to previous generations of Bluetooth LE modules,” leading to longer battery life or smaller batteries in end products. Both modules are classified as open CPU […]

Toshiba M4K Group microcontrollers for motor control get expanded flash & memory capacity

Toshiba has included eight new products with 512KB/1MB flash storage capacity and four packages in its M4K Group of Arm Cortex-M4-powered microcontrollers. The M4K Group is part of Toshiba’s TXZ+ Family Advanced Class, consisting of five groups of low-power, high-performance 32-bit microcontrollers. The new microcontrollers expand code flash memory to 512KB/1MB from the 256KB maximum supported by current products, and RAM capacity to 64KB from 24KB. They retain the Arm Cortex-M4 core, integrated code flash, and 32KB data flash memory (with 100K program/erase cycles). With different motor control options such as advanced programmable motor circuits, advanced 32-bit encoders, advanced vector engine plus, and three units of high-speed, high-resolution 12-bit analog/digital converters, these class of microcontrollers are quite capable of 3-motor control, even in small scale applications (64-pin). The new products with 1MB code flash separate the memory into two distinct 512KB areas, enabling memory swap and seamless over-the-air firmware updates, […]
