There Is A Cost To Extended Lifetime Products. It’s 7.5%.

Silicon and integrated circuits come and go, but when it comes to extended lifetime support from a company, it’s very, very hard to find fault with Microchip. They’re still selling the chip — new — that was the foundation of the Basic Stamp. That’s a part that’s being sold for twenty-five years. You can hardly find that sort of product support with a company that doesn’t deal in high-tech manufacturing.

While the good times of nearly unlimited support for products that are decades old isn’t coming to an end, it now has a cost. According to a press release from …read more

Profiles in Science: Jack Kilby and the Integrated Circuit

Sixty years ago this month, an unassuming but gifted engineer sitting in a lonely lab at Texas Instruments penned a few lines in his notebook about his ideas for building complete circuits on a single slab of semiconductor. He had no way of knowing if his idea would even work; the idea that it would become one of the key technologies of the 20th century that would rapidly change everything about the world would have seemed like a fantasy to him.

We’ve covered the story of how the integrated circuit came to be, and the ensuing patent battle that would …read more

Microchip ICD4 REview

[Mike] is an avid PIC developer and replaced his ICD3 debugger for an ICD4. He made a video with his impressions and you can see it below. [Mike] found the heavy aluminum case with a sexy LED attractive, but wondered why he was paying for that in a development tool. He was also unhappy that they replaced the ICD3 cable connections with new connectors. Finally, he wished for the pin out to be printed on the case.

On the other hand, the ICD4 will also do JTAG and handle the Atmel parts (which Microchip acquired). [Mike] opens the box and …read more

Digitool Helps Debugging

Logic analyzers used to be large boxes full of high-speed logic and a display monitor. Today, they are more likely to be a small box with a USB port that feeds data to a PC application. [Juan Antonio Rubia Mena] wanted something more self-contained, so he built Digitool. Built around a PIC18F2525, the device can measure frequency up to 10 MHz and inject square waves up to 1 MHz into the circuit under test. Oh yeah. It also has a simple four-channel logic analyzer that displays on a tiny LCD.

The 500,000 sample per second rate and the 1024 sample …read more

Friday Hack Chat: 8-Bit Micros With Microchip

A few years ago, Microchip acquired Atmel for $3.56 Billion. There are plenty of manufacturers of 8-bit microcontrollers, but everyone makes 8051s, and the MSP430 isn’t as popular as it should be. Microchip’s acquisition of Atmel created what is probably the largest manufacturer of 8-bit micros, with a portfolio ranging from ATtinys smaller than a grain of rice to gigantic PICs.

This Friday, we’re hosting a Hack Chat with the Technical Marketing Engineer of 8-bitters at Microchip. If you love AVR, this is the guy to talk to. If you’re still rocking the vintage 1993 PICkit, this is the guy …read more

Microchip’s PIC32MZ DA — The Microcontroller With A GPU

When it comes to displays, there is a gap between a traditional microcontroller and a Linux system-on-a-chip (SoC). The SoC that lives in a smartphone will always have enough RAM for a framebuffer and usually has a few pins dedicated to an LCD interface. Today, Microchip has announced a microcontroller that blurs the lines between what can be done with an SoC and what can be done with a microcontroller. The PIC32MZ ‘DA’ family of microcontrollers is designed for graphics applications and comes with a boatload of RAM and a dedicated GPU.

The key feature for this chip is a …read more

Microchip Launches New Family Of PICs

Over the last few years, we’ve seen projects and products slowly move from 8-bit microcontrollers to more powerful ARM microcontrollers. The reason for this is simple — if you want to do more stuff, like an Internet-connected toaster, you need more bits, more Flash, and more processing power. This doesn’t mean 8-bit microcontrollers are dead, though. Eight bit micros are still going strong, and this week Microchip announced their latest family of 8-bit microcontrollers.

The PIC16F15386 family of microcontrollers is Microchip’s latest addition to their portfolio of 8-bit chips. This family of microcontrollers is Microchip’s ‘everything and the kitchen sink’ …read more

Arduino with a… PIC?

Before the Arduino took over the hobby market (well, at least the 8-bit segment of it), most hackers used PIC processors. They were cheap, easy to program, had a good toolchain, and were at the heart of the Basic Stamp, which was the gateway drug for many microcontroller developers.

[AXR AMR] has been working with the Pinguino, an Arduino processor based on a PIC (granted, an 18F PIC, although you can also use a 32-bit device, too). He shows you how to build a compatible circuit on a breadboard with about a dozen parts. The PIC has built-in USB. Once …read more
