Using a Desktop Laser Engraver to Probe into Chip Silicon

Laser fault injection is a common method of attacking devices, but sometimes we want to first understand what a device looks like or what certain blocks on the surface of the device die are. This article shows how you can use a low-cost laser engraver to map out these blocks, even without more advanced fault injection equipment.

STMicroelectronics' New Automotive Linear Voltage Regulator Preserves Battery Energy in Challenging Conditions

The TL99VR03 300mA low-dropout (LDO) regulator provides resilient and efficient power, with a wide input-voltage range and very low quiescent current consumption, only 3.5µA at no load. The IC has an enable pin for turning the regulator off, which reduces the idle current to 800nA, and integrates soft-start circuitry to limit current during power-up and fault recovery.
