Freescale Announces Availability of Kinetis L Series Cortex M0+ MCU and Freedom Devkit

ARM unveiled its ultra-low power Cortex-M0+ core back in March, and Freescale and NXP also announced their plans to use this new core in some of their micro-controllers destined to power the internet of things. Yesterday at Freescale Technology Forum (FTF), Freescale announced the availability of alpha samples of its Kinetis L series. This new low power MCU family will allow existing 8-bit and 16-bit architecture to be replaced by 32-bit architecture without increasing power consumption, cost or size, and the company expects them to be used in devices such as small appliances, gaming accessories, portable medical systems, audio systems, smart meters, lighting and power control. The ARM Cortex-M0+ processor is said to consume about a third of the energy of any 8- or 16-bit processor, while delivering between two to 40 times more performance. Kinetis L series MCU can consume as low as 50 uA/MHz in very-low-power run (VLPR) […]

Texas Instruments Launchpad MSP-EXP430G2 & Capacitive Touch Booster

This is a guest post about the low cost Launchpad MCU devkit. This kit was unveiled in 2010, but since I’d never written about this $4.30 development kit previously, I’ve accepted to publish the post below with slight modifications and amendments. You may be itching to get started with a micro-controller based project but held back because of the high cost of the development boards, and the complex nature of tools required. The good news is that Texas Instruments have come up with a development kit – including a board and the required development software tools. This tool is intended for beginners as well as experienced users. In fact, at under $5, the Texas Instruments’ LaunchPad gives you a complete environment in which you can get started with your projects. This LaunchPad Development Kit is a part of the Texas Instruments MSP430 Value Line series of micro-controllers. You can program, […]

Freescale Announces Kinetis KW20 Cortex M4 MCU with Built-in Zigbee Transceiver

Freescale announced the addition of the Kinetis KW20 to its Kinetis microcontroller portfolio. The Kinetis KW20 is based on ARMCortex-M4 core and MC13242 RF transceiver to deliver a single chip Zigbee solution for the Internet of Things and power applications such as smart energy, smart metering and building control. The company explains that their new wireless MCU family aims to “address the increased processing and memory requirements associated with future ZigBee Smart Energy 2.0 and Internet Protocol specifications”. The KW20 supports dual personal area network (PAN) to enable a single device to communicate wirelessly on two ZigBee networks. This feature eliminates the need for multiple radios required to connect different home automation and smart energy networks. Kinetis KW20 wireless MCU features: ARM Cortex-M4 processor core Up to 512 KB of flash memory and 64 KB of RAM Cryptology accelerator and sophisticated tamper detect Integrated IEEE 802.15.4-compliant radio (MC13242 RF transceiver) Low […]

Toshiba Unveils TMPM061 Cortex-M0 MCU for Smart Meters

Toshiba America Electronic Components (TAEC) has announced the TMPM061, a new 32-bit ARM Cortex-M0 MCU specifically designed for smart metering applications. This new micro-controller provides a single chip solution for smart meters, eliminating the need for the two-chip approach with an analog front end (AFE) and a MCU, delivering a smaller footprint and lower costs. In order to simplify smart meter power measurement, the TMPM061 features an onboard power calculation engine that can calculate active energy, reactive energy and power factor as well as monitoring voltage and frequency fluctuation. In addition, the TMPM061 features up to 128KB on-chip Flash ROM and 8KB on-chip RAM, as well as on-board peripherals including: 3-channel 24-bit Delta-Sigma analog-to-digital converter (ADC) supporting sampling up to 6 kHz 10-bit ADC Temperature-compensated real-time clock (RTC). 9-channel 16-bit timer LCD display controller Temperature sensor Voltage detection circuit Watchdog timer 5-channel general-purpose serial interface Serial bus interface (I2C bus mode or […]

Energy Micro EFM32 Tiny Gecko (Cortex-M3) Starter Kit Unboxing

I’ve been lucky recently, after winning a TI Piccolo controlStick last month, I’ve just received Energy Micro EFM32 Starter Kit (EFM32-TG-STK3300) based on EFM32 Tiny Gecko MCU. This development board include: EFM32 Tiny Gecko Cortex-M3 MCU 8×20 LCD A light sensor A touch slider A battery compartment SEGGER J-Link mini USB port 2 Button + 1 reset button 1 User LEDs 2 expansion ports. Lots of through holes to access the different pins of the MCU Today, I’ll just show the content of the kit and next time, I’ll post more about the things I’ve done with it. Here’s the package of the EFM32 Starter Kit. The 2 gecko eggs were not included… Actually, those are house geckos eggs which are smaller than real geckos. We’ve got those here as well, but there are very shy, whereas house geckos just run around the walls and ceilings all day. Well, it’s […]
