FutureWatch: Sophisticated & Smart Surveillance Electronics To Become Smaller and Cheaper

Texas Instruments says it has shrunk the size of the smallest microcontroller unit in its industry with a new MCU the size of a black pepper flake.

The MCU packaging is only 1.38 square millimeters in size... TI says the product is aimed at small products including medical wearables, earbuds, stylus pens and electric toothbrushes. The product includes a 12-bit analog-to-digital converter and has 16KB of flash memory and 1KB of SRAM and runs at 24MHz...

TI says the microcontroller costs 20 cents per unit in quantities of 1,000, which means a company could get an army of robot spiders project started for as little as $200.

Vinay Agarwal, vice president and general manager of MSP Microcontrollers at TI: "With the addition of the world's smallest MCU, our MSPM0 MCU portfolio provides unlimited possibilities to enable smarter, more connected experiences in our day-to-day lives."

William Luk, a consultant and technology expert at Quandary Peak Research, said the MCU shrinkage opens up opportunities in areas where miniature devices weren't previously possible.

"One of the important verticals for micro-devices is in healthcare and surgical: smart pills, embedded sensors, or even surgical devices that can reach places like never before," Luk said. more
