ATTiny85 board A First Look and review

educ8s.tv wanted to take a look at this tiny board for a long time. It is very small size, it is low cost and it uses a different processor than the Arduino boards. It uses the ATTiny 85 microcontroller chip, which can operate at a frequency up to 20Mhz. It has 8Kb of flash memory, 512bytes of RAM memory and 6 I/O pins 2 of which can implement the I2C protocol. It is very small in size and has low power requirements. We can program it using the Arduino IDE, which makes things so much easier! I got this tiny board with a USB interface in order to be easier to program. You can find a link for this ATtiny85 board in the description of the video.

educ8s.tv wanted to test if the ATtiny85 board is a good option for simple projects and if we achieve longer battery life with this board that a standard Arduino mini. Let’s find out together.

Atmel SAM D09 Development board

samd09brk1-600

Dan Watson has designed a development board for the Atmel SAM D09 microcontroller:

The Atmel SAM D series of 32-bit microcontrollers includes several devices, each with a long list of features at great prices. Perhaps the best known of the series in the maker community is the SAM D21 due to its use on the Arduino Zero. However, there are several other devices in the product line that are worth taking a look at. The smallest of the bunch is the SAM D09 that comes in a 14-pin SOIC package. The 14SOIC package is one of my favorites. It is easy to solder, easy to break out on a PCB, and takes up little board space. I decided to order some SAM D09C chips and design a small development board in order to learn more about the capabilities of the device.

ATtiny10 Mini Breakout Board

ATtiny10-MiniBreakoutBoard

Dan Watson has designed a tiny breakout board for the Atmel ATtiny10. The board includes a bypass capacitor, a power LED and a user LED:

This breakout board is for the ATtiny10 microcontroller. The PCB is 0.25×0.325″ and uses 0.050″ header pins. The board could actually be made smaller, but I ran into the minimum PCB size limit on OSHPark. Despite the tiny size, I was able to include a 100nF bypass capacitor, power LED, and a user LED on pin PB1. That pin is also the clock pin for the programming interface, so it flashed when the board is being programmed.

mavroOBD – Arduino based OBD port module

mavroOBD-rev3-1-650x452

Danny Mavromatis has designed an Arduino based OBD port module using Atmel 328P MCU and Microchip MCP2515 CAN Bus controller with SPI interface and MCP2551 CAN transceiver.

The goal of this project it to create an Arduino based OBD port module that can be used to enhance a vehicles capabilites. For example, if you want door locks to close when moving faster than 5mph or to invoke/emulate certain CANbus buttons automatically at start up.

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.
