| Two Microchip Controller Families
Boast eSPI Bus Support Microhip Technology has made available its MEC17XX and MEC14XX families of embedded controllers with enhanced Serial Peripheral Interface (eSPI). The eSPI bus is the host interface supported by the latest PC computing chip sets and is required for new, upcoming computing applications. The MEC17XX family is based on an ARM Cortex-M4F core and has advanced hardware-accelerated cryptography algorithms to efficiently support the secure boot of a computer. The family offers several additional features including two UARTS and an extended industrial operating temperature range that make the family ideal for industrial computing. In addition, Microchip's MIPS-based MEC14XX family has been expanded to include functionality for supporting the new eSPI Slave Attached Flash (SAF) feature, which allows the Microchip embedded controller to be directly connected to an SPI flash memory using an on-board master controller. CONTINUE READING Tool Solutions Emerge for Cypress Semi's PSoC BLE 6 Microcontroller Cypress Semiconductor has announced the public release of the PSoC 6 BLE Pioneer Kit and PSoC Creator Integrated Design Environment (IDE) software version 4.2 that enables designers to begin development with the PSoC 6 microcontroller (MCU) for IoT applications. PSoC BLE 6 is a low power, flexible MCU with built-in Bluetooth Low Energy (BLE) wireless connectivity and integrated hardware-based security in a single device.
Early adopters are already using the flexible dual-core architecture of PSoC 6, using the ARM Cortex-M4 core as a host processor and the Cortex-M0+ core to manage peripheral functions such as capacitive sensing, BLE connectivity and sensor aggregation. Early adopter applications include wearables, personal medical devices, and wireless speakers. Designers are also exploiting the built-in security features in PSoC 6 to help guard against unwanted access to data. The PSoC BLE Pioneer Kit features a PSoC 63 MCU with BLE connectivity. The kit enables development of modern touch and gesture-based interfaces that are robust and reliable with a linear slider, touch buttons, and proximity sensors based on the latest generation of Cypress' CapSense capacitive-sensing technology. Designers can also use the board to add USB Power Delivery (PD) with its Cypress EZ-PD CCG3 USB-C controller. The kit also includes a 2.7" E-ink Display Shield add-on board (CY8CKIT-028-EPD) with thermistor, digital mic., and 9-axes motion sensor. CONTINUE READING |

Ultrasonic Sensing MCUs Target Smart Water Meters Texas Instruments (TI) has unveiled a new family of MSP430 microcontrollers with an integrated ultrasonic sensing analog front end that enables smart water meters to deliver higher accuracy and lower power consumption. In addition, TI introduced two new reference designs that make it easier to design modules for adding automated meter reading (AMR) capabilities to existing mechanical water meters. The new MCUs and reference designs support the growing demand for more accurate water meters and remote meter reading to enable efficient water resource management, accurate measurement, and timely billing.
As part of the ultra-low-power MSP430 MCU portfolio for sensing and measurement, the new MSP430FR6047 MCU family lets developers add more intelligence to flow meters by taking advantage of a complete waveform capture feature and analog-to-digital converter (ADC)-based signal processing. This technique enables more accurate measurement than competitive devices, with precision of 25 ps or better, even at flow rates of less than 1 liter per hour. In addition, the integrated MSP430FR6047 devices reduce water meter system component count by 50% and power consumption by 25%, enabling a meter to operate without having to charge the battery for 10 or more years.

Multicore ARM-based SoC Targets Secure Net Acceleration
NXP Semiconductors has announced the highest performance member of its Layerscape family, the LX2160A SoC. The LX2160A is specifically designed to enable challenging high-performance network applications, network edge computing, and data center offloads. Trusted and secure execution of virtualized cloud workloads at the edge is driving new distributed computing paradigms.
The LX2160A features sixteen high-performance ARM Cortex-A72 cores running at over 2 GHz in a sub 30 W power envelope, supporting both the 100 Gbit/s Ethernet and PCIe Gen4 interconnect standards. In addition, it provides L2 switching at wire rate and includes acceleration for data compression and 50 Gbit/s IPSec cryptography. CONTINUE READING
