Microchip’s first ARM processor with cryptographic engine

In Production The CEC1302 incorporates a high-performance 32-bit ARM® Cortex®-M4 embedded microcontroller with 128 Kilobytes of SRAM and 32 Kilobytes of Boot ROM. It communicates with the system host using the I2C bus. The CEC1302 has two SPI memory interfaces that allow the EC to read its code from external SPI flash memory: private SPI and/or shared SPI. The Shared SPI interface allows for EC code to be s ...

Chip firm puts 3D sensing devices technology into first

Description The AS5410 allows absolute position sensing of a simple two-pole magnet immediately after starting up the device without the need for a prior reference run within the application. Position sensing is possible over large mechanical travel distances even with very small magnets: a travel distance of 40mm does not pose a problem for a small, 4 x 4 x 3 mm sized NeFeB magnet, for example. Moreover, t ...

Windows 95 on an Apple Watch

I installed Windows 95 on my Apple Watch With a 520 MHz processor, 512 MB of RAM, and 8GB of internal storage, the Apple Watch packs a lot of computing horsepower into a very small package. On paper, its processor alone is about twenty-five times faster than the average 386, and 512 MB was the size of a hard drive in the mid nineties, not memory. As a result, I was feeling confident that the Apple Watch had ...

Off-line LED controllers get dimming and PFC

Description The LT3799 is an isolated flyback controller with power factor correction specifically designed for driving LEDs. The controller operates using critical conduction mode allowing the use of a small transformer. Using a novel current sensing scheme, the controller is able to deliver a well regulated current to the secondary side without using an opto-coupler. A strong gate driver is included to dr ...

Narrow beam angles from small LED packages

Following research at Sheffield-based LED packaging firm Litecool, narrow beam angles from LED packages without secondary optics or reflectors look closer. The proof-of-concept device produced a beam with 50% of light in 36 degrees, and over 90% efficiency. “Most package manufacturers design their LED packages for maximum light extraction. This means as little manipulation of the light as possible and just ...
