CHIPS (ELECTRONICS)CONTROLLERSCOUNTERSA pipeline binary updown counter with many bits is developed which can be used in a variety of applications. One such application includes the design of a digital correlator for very long baseline interferometry (VLBI). The advantage of the presently conceived ...
down converter regulator to directly supply VCORE or an external circuitry • Embedded regulator (LDO) with configurable scalable output to supply the digital circuitry • Voltage scaling in Run and Stop mode • Backup regulator (~0.9 V) • Low-power modes: Sleep, Stop and Standby • ...
The internal power-on reset (POR) / power-down reset (PDR) circuitry is disabled through the PDR_ON pin. An external power supply supervisor should monitor VDD and maintain the device in reset mode as long as VDD is below a specified threshold. PDR_ON must be connected to VSS, to let...
TK Stealth isn't a particularly expensive keyboard, doesn't have hot-swappable switches and needed me to dismantle it and soak the outer shell in petrol to strip off all the soft-touch finish that broke down into sticky tar after 5-6 years of exposure to the UV light in normal daylight...
This 43-range one below was pretty special to me in the late 1970's when I was making under $4/hour and Radio Shack had them for $49.95 IIRC (which would be somewhere near $200 in 2014 dollars) and then they brought them down under $30 on sale, and I grabbed one! It was much...
If you did that it would make the day of the people on the security part of check in, with the type of gear you are talking about their faces would be a picture. I once knew someone who used to go over to the US a few times a year and would strip down a telescope (tripod and...
“number crunching” is completed, it still comes down to analog electronics. This is especially true with ever-increasing speeds now employed — not to mention I/O ports to the real world such as sensors, etc. In reality, there is only one wave shape in the physics of electronics: the ...
STM32H725xE/G devices operate in the –40 to +125 °C ambient temperature range from a 1.62 to 3.6 V power supply. The supply voltage can drop down to 1.62 V by using an external power supervisor (see Section 3.7.2: Power supply supervisor) and connecting the PDR_ON pin to VSS. ...
a plurality of up/down counters, each operable to count in a first direction during said first sampling interval and in an opposite direction during said second sampling interval, each of said up/down counters being responsive to an output of one of said comparators to stop counting during each...
