Just last week, there was considerable speculation that Microchip would buy Atmel. The deal wasn’t done, and there was precedent that this deal wouldn’t happen – earlier this year, Dialog made an approach at Atmel. Now, though, the deal is done: Microchip will acquire Atmel for $3.56 Billion.
There are three main companies out there making microcontrollers that are neither ancient 8051 clones or ARM devices: TI’s MSP430 series, Microchip and Atmel. Microchip has the very, very popular PIC series microcontrollers, which can be found in everything. Atmel’s portfolio includes the AVR line of microcontrollers, which are also found in everything. From phones to computers to toasters, there’s a very high probablitiy you’re going to find something produced by either Atmel or Microchip somewhere within 15 feet of your person right now.
For the hobbyist electronic enthusiast, this has led to the closest thing we have to a holy war. Atmel chips were a little easier (and cheaper) to program, but were a little more expensive. Microchip’s chips have a very long history and proportionally more proper engineers who are advocates. PIC isn’t Arduino, though, a community that has built a large and widely used code base around the AVR family.
Microchip’s acquisition of Atmel follows several mergers and acquisitions in recent months: NXP and Freescale, Intel and Altera, Avago and Broadcom, and On Semiconductor and Fairchild. The semiconductor industry has cash and wants to spend it. What this means for the Atmel product line is left to be seen. The most popular micros probably won’t be discontinued, but if you’re using unpopular Atmel micros such as the ATtiny10 you might want to grab a reel or two before they’re EOL’d.
A proposal from Microchip to acquire Atmel has been deemed a ‘superior proposal’ by Atmel’s board of directors (PDF). This is the first step in the acquisition of a merger between Microchip and Atmel, both leading semiconductor companies that have had a tremendous impact in the electronics industry.
Microchip is a leading manufacturer of microcontrollers, most famously the PIC series of micros that can be found in any and every type of electronic device. Atmel, likewise, also has a large portfolio of microcontrollers and memory devices that are found in every type of electronic device. Engineers, hackers, and electronic hobbyists are frequently sided with Microchip’s PIC line or Atmel’s AVR line of microcontrollers. It’s the closest thing we have to a holy war in electronics.
Last September, Dialog
acquired announced plans to acquire Atmel for $4.6 Billion. Today’s news of a possible acquisition of Atmel by Microchip follows even larger mergers such as NXP and Freescale, Intel and Altera, Avago and Broadcom, On Semiconductor and Fairchild, and TI and Maxim. The semiconductor industry has cash on hand and costs to cut, these mergers and acquisitions are the natural order of things.
While the deal is not done, the money is on the table, and Atmel’s board is apparently interested.
A few years ago [Serge Vakulenko] started the RetroBSD project–a 16-bit port of the old 2.11BSD operating system to the Microchip PIC32 microcontroller. This was impressive, but version 2 of BSD is, to most people, old news and somewhat difficult to use compared to modern BSD and Linux operating systems.
[Serge] has been at it again, however, and now has a port of 4.4BSD–LiteBSD–running on the PIC32MZ. According to [Alexandru Voica] there is about 200K of user space memory in the basic build, and by removing some OS features, you could double or triple that figure.

Microchip has unveiled a new dev board called the Curiosity Development Board. I had my first look at this at Bay Area Maker Faire back in May but was asked not to publicize the hardware since it wasn’t officially released yet. Yesterday I got my hands on one of the first “pilot program” demo units and spent some time working with it.
I requested a sample board out of my own curiosity. As you may know, Microchip is one of the sponsors of the 2015 Hackaday Prize, but that partnership does not include this review. However, since we do have this relationship we asked if they would throw in a few extra boards that we could give away and they obliged. More about that at the end of the post.

While development boards for micro controllers are nothing ground breaking, they can be expensive, and often times overkill for what you’re doing when they try to put everything you might use … including the kitchen sink. when [Brian] noticed his projects were starting to use Microchip PIC24 more and more, the time came to have a dev board on hand.
The result is a small board with breakouts for USB, UART (via FTDI), of course tons of GPIO pins, and a socket which mates with a daughter board to swap out either a PIC24FJ128GC006, or a DSPIC33EP256MU806, with the potential for more. Also packed on the board is a power regulator system and dual crystals allowing full speed operation or power sipping modes.
Schematics and PCB layout are available (in Diptrace format) along with a board template file to use with MPLAB on github.com. Once you have everything together you will need a PIC programmer, [Brian] is using a trusty Microchip MPLAB ICD 3 programmer, but naturally, others are available.
Microchip recently announced a new development board of their own for the PIC16F series. The Curiosity board has built-in support for programming and debugging (no chipKIT needed). The engineer who designed that board, [John Mouton] is going to join us on July 30th for a live chat about the design process. We’re also going to be giving away some of the first boards to come off the production line… more about that this coming week.
For the last few weeks we’ve been celebrating builds that use parts from our manufacturer sponsors of the 2015 Hackaday Prize. Today we are happy to announce 50 winners who used Microchip parts in their builds. Making the cut is one thing, but rising to the top is another. These builds show off some amazing work from those who entered them. In addition to the prizes which we’ll be sending out, we’d like these projects to receive the recognition they deserve. Please take the time to click through to the projects, explore what has been accomplished, and leave congratulations a comment on the project page.
Still Time to Win!
We’re far from the end of the line. We’ll be giving roughly $17,000 more in prizes before the entry round closes in the middle of August. Enter your build now for a chance in these weekly contests! This week we’re looking for things that move in our Wings, Wheels, and Propellers Contest.
One voter will win $1000 from the Hackaday Store this week as well! Anyone is welcome to vote in Astronaut or Not. Vote Now! The drawing is tomorrow afternoon.

[Rui] enjoys his remote-controlled helicopter hobby and he was looking for a way to better track the temperature of the helicopter’s engine. According to [Rui], engine temperature can affect the performance of the craft, as well as the longevity and durability of the engine. He ended up building his own temperature logger from scratch.
The data logger runs from a PIC 16F88 microcontroller mounted to a circuit board. The PIC reads temperature data from a LM35 temperature sensor. This device can detect temperatures up to 140 degrees Celsius. The temperature sensor is mounted to the engine using Arctic Alumina Silver paste. The paste acts as a glue, holding the sensor in place. The circuit also contains a Microchip 24LC512 EEPROM separated into four blocks. This allows [Rui] to easily make four separate data recordings. His data logger can record up to 15 minutes of data per memory block at two samples per second.
Three buttons on the circuit allow for control over the memory. One button selects which of the four memory banks are being accessed. A second button changes modes between reading, writing, and erasing. The third button actually starts or stops the reading or writing action. The board contains an RS232 port to read the data onto a computer. The circuit is powered via two AA batteries. Combined, these batteries don’t put out the full 5V required for the circuit. [Rui] included a DC-DC converter in order to boost the voltage up high enough.
