Energy Micro Unveils 2 New Gecko Cortex M3 Starter Kits: EFM32LG-STK3600 and EFM32GG-STK3700

Energy Micro introduced two starter kits (STK) for complex battery-powered products such as portable health and fitness devices and smart accessories: EFM32LG-STK3600 – Based on the EFM32LG990F256 MCU (Cortex M3 ) with 256KB on-chip flash and 32KB RAM. EFM32GG-STK3700 – Based on the EFM32GG990F1024 MCU (Cortex M3 ) with 1MB on-chip Flash and 128KB RAM Both the Leopard Gecko and Giant Gecko MCU can directly control a TFT display and feature a USB driver that supports the Host, Device and On-the-Go (OTG) protocols. The new STKs are also equipped with light, metal and touch sensors which allow designers to work with the LESENSE Low Energy Sensor interface allowing passive sensing of 16 sensors without host CPU intervention. The hardware feature set is completed by a USB plug, 32MB on-board NAND Flash, LCD and a variety of LEDs and push-buttons. The two EFM32 starter kits includes debugging support with a  full […]

Qualcomm Atheros AR4100P Provides WiFi Connectivity to the Internet of Things

In January, Texas Instruments was the first company (to my knowledge) to release a WiFi chip for the internet of things, the SimpleLink Wi-Fi CC3000, where WiFi is mostly implemented in hardware to lower power consumption. Now, the company has some competition with the announcement of Qualcomm Atheros AR4100P, an improved version of its AP4100 WiFi chipset, including IPv4/IPv6 support. The AR4100 targets the home, enterprise, smart grid and home automation and control applications that have lower data rates and transmit or receive data on an infrequent basis. The AR4100 system-in-package (SIP) features the following: Low energy Power saving modes as low as 5 µA Wake-up times as low as 2.2 ms Support for Quad SPI flash for faster wake times Low system resource requirements Low footprint host driver (25K Flash and 8K RAM) Simple, low-cost wireless system integration LGA package simplifies 2- or 4-layer PCB design Near zero RBOM […]

Energy Micro Announces EFM32G-DK3550 Gecko (Cortex-M3) Development Kit

Energy Micro has just announced the availability of the EFM32G-DK3550 development kit based on ARM Cortex-M3 EFM32G890F128 MCU. The kit (pictured below) is based on the main board from the bigger Leopard and Giant Gecko kits and supports SEGGER J-Trace and J-Link in order to reduce the need for additional debugging tools. Here are the development kit specifications: EFM32G890F128 Gecko Cortex-M3 MCU 4MB PSRAM 16MB NOR-Flash 320 x 240 RGB resistive touch TFT display Ethernet MAC/PHY microSD slot audio I/O and I2S DAC USB debug interface, SEGGER J-Link debugger Advanced Energy Monitoring (AEM) system to monitor the prototype’s energy consumption. 2x RS232,  IrDA Switches, Joystick, LEDs, potentiometer… EXP32 Prototyping area (right side of the picture) For software development, Energy Micro provides Simplicity Studio suite, which includes energyAware Profiler that can interface with the AEM system via USB, gather all relevant system data, and display real-time graphs of current consumption on a […]

Energy Micro Introduces Cortex-M4F EFM32 Wonder Gecko MCU Series

Energy Micro has just announced the EFM32 Wonder Gecko series with the addition of 60 ARM Cortex-M4F  based MCU to its Gecko offering or a total of 240 MCUs. The new controllers are highly energy efficient and minimize energy consumption by including a flexible range of standby and sleep modes, intelligent peripherals that allow designers to implement many functions without CPU wake-up, and ultra-low standby current. Wonder Gecko MCUs come with 256KB Flash memory and 32KB RAM and can achieve active mode current consumption of just 180µA/MHz. Devices provide a deep sleep mode that consumes just 400nA with RTC running, a shut-off mode requiring only 20nA and wake-up time as short as 2µs. The company explains that the LESENSE function block, a generic low energy sensor interface, enables monitoring of a mix of up to 16 capacitive, inductive or resistive sensors while the MCU core is in sleep or shut-off […]
