Intel Unveils Three New Micro-controllers for IoT: Quark D1000, Quark D2000, and Quark SE

Intel’s subsidiary, Wind River, has recently announced two operating systems for the Internet of things with Rocket RTOS and Pulsar Linux supported respectively by Quark MCUs, and Intel Atom processors, as well as some ARM SoCs. But it’s not the only “IoT” announcement made by Intel in the last week, as I found out via EETimes that the company also unveiled three new Quark SoCs, namely Quark D1000, and Quark D2000, and Quark SE.

Intel Quark D1000

Contrary to previous Quark processor and the upcoming D2000 and SE processors, D1000 is not compatible with x86 instructions set, and features the following:

• 32-bit Harvard CISC CPU @ 33 MHz with single cycle barrel shifter, two cycle multiplier, multi-cycle divider, integrated 32-bit timer, programmable interrupt controller, and JTAG debugger.
• 128-bit wide 32 kB code flash and 8 kB ROM

Intel Quark D1000 product page is up, where you can read a shorter features summary, and access the datasheet and a user guide. Intel still publishes TDP for Quark, and it might be the first true low power Intel micro-controller with 0.025W TDP @ 33MHz, and 1.6mW configurable TDP @ 1 MHz. Intel expects D1000 MCU to target “battery-powered and line-powered sensors to provide secure, intelligent processing for wired and wireless real-world  applications at the edge”.

Intel Quark D2000 product page provides access to a product brief, but the datasheet is only available to holders of “Intel Embedded Design Center (Intel EDC) Privileged account”. D2000 micro-controllers are expected to be used in industrial applications (smart readers), medical applications (sensor and device controllers), for display controllers in the retail space, and motor controllers in buildings.

Intel Quark SE product page also only has the product brief currently publicly available, and Intel targets the same applications as Intel Quark D2000.

All three platforms will be supported by Intel System Studio for Microcontrollers, an Eclipse-based suite, but I could not find much details about this tool so far, and it’s unclear if it is the same, and if not, how much it differs from Intel System Studio for IoT.

The Intel Quark D1000 MCU is available right now, while Intel Quark  D2000 will be available by the end of the year, and Intel Quark SE SoC is scheduled for H1 2016. Beside product pages on Intel website listed above, you could also find some more info on Mouser’s Quark D1000, Quark D2000, and Quark SE pages where I found some block diagrams. [Update: Quark D1000 price is $3.9 for one piece, and $2.6 per unit for 1k order on Mouser]
