More cores in XMOS’ MCUs address complex audio XMOS’latest family of multicore microcontrollers, the xCORE-200 packs up to 16 independent 32-bit RISC processor cores for the XE216 device. With multiple processing cores executing completely independently, tasks are guaranteed to complete within a strict timing budget. Because the cores are tightly interconnected through a dedicated switch, responding to events triggered by I/O pins, timers and tasks, rather than interrupts, response times are measured in nanoseconds. That’s three orders of magnitude faster than traditional microcontrollers and the main claim of XMOS xCORE architecture. The XE216 can deliver up to up to 2000MIPs for general purpose and DSP processing and supporting up to 512Kbytes of embedded SRAM memory. Already shipping to selected customers, the multicore microcontroller family also supports 10/100/1000 Gigabit Ethernet with a programmable MAC layer and Internet webserver support, opening up Gigabit-speed Internet-of-Things applications. Offering top MCU performance with flexible core processing power allocation (transparently configured through the companys xTIME-Composer Studio development tools), the new devices are said to deliver twice the performance and four times the on-chip SRAM memory of the companys first generation xCORE multicore microcontrollers. They add a flexible Gigabit Ethernet port alongside a high performance and programmable XMOS USB 2.0 interface, and devices will be available with up to 2Mbytes of on-chip Flash memory for system-level integration and security. Delivered in a 128-pin TQFP package, the XE216-512-TQ128 will cost less than USD4.75 in high volume and a complete family of devices will become available over the next few months ranging from products with 8 high-performance 32bit-RISC-processors, up to devices with 10, 12 and 16 cores. The companys roadmap for the second half of 2015 includes xCORE-200 products with 24 and 32 high-performance 32-bit-processor cores XMOS www.xmos.com Next-generation PMBus controller for FPGA, ASIC and processor power Powervation’s latest high-performance digital DC/DC controller for FPGA, ASIC, and point-of-load power for communications and computing applications is designed for key rails that demand precision output voltage regulation and tight control during transient conditions. The PV3105 digital controller provides low jitter and low output voltage ripple, and improved transient response, suiting it for powering low-voltage, high current rails on leading process nodes for ASICs/FPGAs. Additional hardware and firmware features have been implemented to further improve the control of the output voltage under static and dynamic conditions. The device provides up to 1.25 MHz switching frequency and implements new digital loop techniques to reduce output voltage setting time. To meet the power needs of advanced ASICs, PV3105 provides support for latest senseFET power stages, precision telemetry and reporting, and includes features such as voltage tracking, margining, and sequencing. The PV3105 provides temperature compensated fault protection, more flexible protection feature settings, and alerts over PMBus are fully configurable and selectable. Fully scalable, PV3105 can be used in single phase mode or can power multi-phase high power loads using Powervation’s DSS current sharing bus. The PV3105 is designed to flexibly operate with all leading FET power stages, to give the designer maximum flexibility for powering the latest FPGAs, ASICs, processors, and POL. The PV3105 comes in a 4x4mm QFN package.
