Microchip to Buy Atmel for Nearly $3.6 Billion

 

MicroAtMelChipMicrochip Technology to Buy Atmel for Nearly $3.6 Billion @ The New York Times.

Microchip Technology agreed to acquire a fellow chipmaker, the Atmel Corporation, for about $3.6 billion, part of a wave of mergers and acquisitions within the semiconductor industry.

Chip makers have been combining to cut costs and build scale for their customers. Microchip agreed to acquire the 37-year-old chipmaker Micrel in May for about $839 million. Microchip purchased Supertex for $394 million in 2014, and the year before that, bought the closely held Brussels-based EqcoLogic for an undisclosed amount.

Microchip joins larger peers in this round of consolidation, including Avago Technologies, which agreed to acquire Broadcom for $37 billion, one of the biggest deals ever within the semiconductor industry.

by Graham Prophet @ edn-europe.com:

Atmel ATmegaS128 AVR microcontrollers are now produced in space-grade quality, including latch-up immunity, ceramic packaging and extended temperature range for next-generation of space applications.

AtmegaS128 – the first µC Rad Tolerant device for Atmel – delivers full wafer lot traceability, 64-lead ceramic package (CQFP), space screening, space qualification according to QML and ESCC flow and total ionising dose up to 30 krad (300 Gy Si) for space applications. The ATMegaS128 is “latch up” immune thanks to a dedicated silicon process: SEL LET > 62.5Mev at 125°C, 8 MHz/3.3V. SEU to heavy ions is estimated to 10-3 error/device/day for Low Earth Orbit applications.

AC energy metering board using an Atmel 90E24 energy metering chip

Here’s my latest project. Its an AC energy metering board using an Atmel 90E24 energy metering chip. The board can either take an ESP8266-12 and run a native C application, or the ESP8266-12 can be omitted, and an external microcontroller can be used to talk to the Atmel 90E24 energy metering chip. I have firmware to support both the AVR and the ESP8266. I built a really nice energy monitoring box using the AVR and a 12864 display.

by Martin Cooke @ elektormagazine.com:

Atmel has announced a new series of Atmel | SMART ARM® Cortex®-A5-based microprocessors (MPUs). Firmly targeted at IoT applications they are said to deliver the world’s lowest power consumption for all MPUs in their class. They deliver sub 200 µA in retention mode with context preserved, 30 µs ultra-fast wake-up and a new backup mode with DDR in self-refresh at only 50 µA. Among the built-in features of the Atmel | SMART SAMA5D2 series includes a complete audio subsystem, lower pin-count and ultra-small package. The integrated PCI-level security capabilities will find applications in IoT devices, wearables and point of sale (POS) equipment.

DIY USB Line Power Meter Stick

DIY-USB-Line-Power-Meter-Stick-Connected-to-Laptop-620x503

a new project is published on electro-labs.com, check it out:

Another DIY project designed with FabStream’s SoloPCB tool is ready to be shared with Electro-Labs community. This is an USB stick which measures the supply voltage of the USB port and current drawn by the device connected to the port over the stick. Then it calculates the power consumption of the device and displays the whole information with the help of the small OLED display on the board. The stick itself is also powered from the USB port.

The board is built around an Atmel ATMEGA328 microcontroller. To make the circuit as small as possible, the MCU is used in minimal configuration. Internal 8MHz oscillator is used. The voltage and the current are measured by the internal 10 bit ADC. To make the measurements more accurate, an external 2.5V voltage reference IC, Microchip MCP1525 is included. The current is converted to voltage on a 0.01R sense resistor and precisely amplified by LT6106 before read. The stick can measure up to 2.5A. Since the OLED display requires 3.3V supply voltage, L78L33ACUTR linear voltage regulator is used.

by Martin Cooke @ elektormagazine.com:

Atmel has recently announced the addition of the SAM L22 series to its family of secure, ARM® Cortex® M0+-based MCUs. These new devices offer a built-in, ultra-low power capacitive touch interface with a segment LCD controller that can deliver up to 320 segments. Typical applications for these controllers would include low-power devices such as thermostats, electric/gas/water meters, home control, medical and access systems.

Their inbuilt features make them suited to IoT applications and the SAM L22 series includes security capabilities to deliver 256-bit AES, cyclic redundancy check (CRC), true random number generator, Flash protection and tamper detection to ensure information is securely stored, delivered and accessible. The devices use Atmel’s proprietary picoPower® technologies for low power consumption and smart low-power peripherals that work independently of the CPU in sleep modes.

Wino… like Arduino, only smaller

20150624024339_Winoby Martin Cooke:

The Wino board is an Arduino-like stackable development system which is both smaller and cheaper than Arduino units and features built-in WiFi as standard.

The main Wino controller board measures 26.5 x 18.5 mm and fitted with an Atmel ATSAMD21 running at 48 MHz with 128 kB Flash storage and 16 kB RAM. The board uses the ESP8266EX WiFi module which supports all the 802.11 b/g/n standards offering P2P and soft-AP modes and TCP-IP / UDP, static IP and DHCP networking. The 27-pin stackable connections around the board periphery provide connections for 15 digital GPIO pins, 6 x 12-bit ADCs and a 1 x 10-bit DAC.
