Lenovo selected the NXP LPC54100 MCU to provide sensor hub functions in its upcoming VIBE X2 Pro smartphone. With as little as 3uA for always-on "sensor listening" and active mode power consumption of 55 uA/MHz for sensor data aggregation, the part is power efficient. Its ARM Cortex-M4 core...
Atmel launched its new ATECC508A, an MCU peripheral for hardware-based security integrating two modern elliptic curve algorithms. The new part implements the ECDH (elliptic curve Diffie-Hellman) security protocol, and ECDSA (elliptic curve digital signature algorithm) for sign-verify...
From the ARM 4Q14 earnings release today:
My observation: the Cortex-M7 blurred the lines in performance with the low end of the Cortex-A family. It will be very interesting where Teal and Grebe come in on the performance/power scale.

TI's line of Hercules MCUs, based on ARM Cortex-R cores running in lockstep, targets safety-critical platforms. The SafeTI software development process for these MCUs has been certified for developing ISO 26262 and IEC 61508 components.
Using LDRA's software analysis tools, TI has created...
A joint project between STMicro and YOGITECH has produced a set of STM32 safety manuals and software test libraries certified to IEC61508:2010 functional safety standards. Application designers can download the STM32 safety manuals free of charge, taking advantage of guidance in testing their...
Toshiba has announced the new TMPM036WRG microcontroller, adding to the TX00 series of microcontrollers based on the ARM Cortex-M0 core. Clocked at up to 20 MHz with 128 KB of on-chip flash, the new family expands 16-bit timer channels from 10 to 14, and adds two SIO/UART channels for a total of...
A big expansion of the Silicon Labs wireless portfolio for the IoT, buying Bluegiga for $61M cash. This is definitely the direction MCU vendors have to go, controlling their own Bluetooth and Wi-Fi technology.

Silicon Labs Acquires Bluegiga, a Leader in Bluetooth and Wi-Fi...
IC Insights has just released its 2015 edition of The McClean Report, now in its 18th year. Today, they announced an excerpt from the report on the microcontroller segment. Factoids from the release:
MCU revenues fell 3% in 2012 and were flat in 2013, mostly due to pullback in smartcards and...
Fitting in the space between a simple LCD interface and a full-up GPU found on SoCs, Spansion has introduced the FM4 S6E2DH microcontroller. It adds a 2D rendering graphics display controller backed by 512KB video RAM to an ARM Cortex-M4 core clocked at 160 MHz with 384 KB flash. Peripherals...
The entry point for ST's ARM Cortex-M4 offering is the STM32F3, clocked at 72 MHz and featuring a floating point unit and DSP extensions. Newest family members now support up to 512 KB flash, additional I2C and SPI ports, and a Flexible Memory Controller. Additional motor-control capability has...
Seeking to reduce MCU die cost by as much as 25%, Synopsys introduces the DesignWare Medium Density NVM IP family. Their approach targets the TSMC 180nm 5V CMOS and BCD process - where NVM rules and embedded flash is scarce - with a solution for up to 64 KB of on-chip memory. They claim the...
Casambi Technologies Oy, a Finnish smart lighting company, has developed a new dual-mode mesh networking solution for lighting. Using the Nordic Semi nRF51822, Casambi claims at least a 5x improvement in mesh network performance using a combination of Bluetooth Smart and proprietary 2.4 GHz...
Renesas is after higher performance industrial automation and IoT applications with their new 32-bit microcontroller family, the RX71M Group. Designed around the RXv2 core, the clock has been upped to an impressive 240 MHz, delivering a 1056 CoreMark figure. Performance has been enhanced with...
Echelon continues to build around their proprietary 80 MHz Neuron 6050 core, extending the IzoT platform for industrial IoT (IIoT) applications. At the AHR 2015 show, new support for BACnet/MS-TP and additional Wi-Fi modules was announced. Demonstrations included a converged building control and...
IP provider CAST Inc. has teamed with design shop Silesia Devices to provide a huge kick to the venerable 8-bit 8051 microcontroller. The new T8051XC3 Tiny 8051 IP core is small. 6.6K gates is all it takes to get a CPU, serial controller, timer/counter, GPIO, interrupt controller, power...
Sony (SNE), in the wake of the recent cyberattacks, says their financial and accounting systems are totally disrupted to the point where they can't count. While saying they don't think their results have been materially affected, they are requesting several weeks of relief in filing their...
Six new devices have been added to ST's ARM Cortex-M0-based STM32F0 Value Line. The changes:
The STM32F030CC and STM32F030RC now have flash of 256MB.
Four new STM32F070 devices add USB 2.0.
This line of MCUs is clocked at up to 48 MHz. They include a 12-bit A/D, 5 channel DMA controller, two...
Targeting home security detectors and motion sensors with a suite of integrated analog peripherals, Renesas introduces the RL78/I1D family of MCUs. In low-power operating mode at a frequency of 1 MHz, current draw is typically 124 uA. Snooze modes allow use of several peripherals without the CPU...
TI has reduced three-phase motor controller tuning to one parameter, plus packaged a whole set of motion control capability in their release of the TI C2000 Piccolo F2806x InstaSPIN-MOTION LaunchPad (yes, that's a mouthful for a product name). The heart of this latest LaunchPad kit is the 90 MHz...
ARM has announced a partnership with University College London (UCL) in hopes of "firing up" IoT engineering. UCL will be rolling out the ARM IoT Education Kit this September in a week-long module for post-graduate EE and continuing professional development students, with hopes of extending the...
