As @GT says, it's a 12-bit ADC, made by Hybrid Systems. Logo from USPTO.
According to this website:
Company: Hybrid Systems Corporation Based: Bedford, Mass.
1967 (merged with Harris Semiconductor spin-off Data Linear in 1986 &
became Sipex Corp.)
Founders: Donald B. Bruck
Specialty: Manufacturer of hybrid integrated circuits, discrete ...
You could enable a dynamic comparator full-time but it would not be plug-compatible yet functionally equivalent as a static converter with the extra pin. Visa versa is not possible unless a flip flop is added.
Dynamic Comparators are often used in high speed ADC's, State Machines and nanotube R&D components for example.
Found it, and deleted my previous answer. How ironic was finding the IC after saying "almost impossible to find" (facepalm).
Anyway, here it is: AOZ1282
What we did wrong was to Google "BN0D" instead of BN0. A simple search for "smd marking BN0 sot-23-6" brought the result.
Could it be a RiCOH RP154?
I used this website for the SMD code:
This side has no direct match for BN0D, but for BN01 to BN09 and they are all the same part, only some variant.
The pin count does match to the photo. It being a volatage regulator makes sense.
The simulator is telling you the problem:
Warning: singular matrix: check nodes unconnected-_u1-pad4_ and unconnected-_u1-pad4_
You need to connect pin 4 to VIN. Even though the datasheet shows this pin unconnected on the first page, you can read further to the pin table to see recommended configurations.
It depends on the circuit and your goals.
If you were using an sram, it would not matter that much as it does not generate values; it only returns whatever the cpu stored in it.
If we were talking about rom devices (eprom, eeprom, flash, etc.) it matters as the cpu must access it at fixed addresses and recover the data patterns in a certain format - it ...
When any amplifier saturates the gain is zero.
When analyzing the small-signal performance of a comparator, we assume it is not saturated and thus operates in the linear region, which is rather difficult as it is not unity gain compensated to do so but may perform well in an open loop with low offset.
This means comparators are not designed for linear ...
The comparator isn't 'active' when the inputs are more than a few mV different in voltage, it's saturated to one rail or the other. The important parameters, propagation delay and input offset, are a function of how the comparator amplifier behaves when in the linear region.
This is only the input stage of a usual opamp (the differential pair) with some constant current biasing circuit around. actual opamps will have at least another stage as output stage. To achieve low output impedance throughout, it should be a push pull stage.
In practice, there is also usually at least one intermediate stage to provide sufficient open loop ...
This will damage the device, and just about any other analog switch that is not powered with VCC = 12 V. From the datasheet, this device has a VCC abs max of 6 V, and no other pin can go above VCC + 0.3 V (the 0.3 V would be the voltage drop of the ESD protection diode when it is on):
Exceeding the abs max will very likely damage the device permanently, as ...
The datasheet absolute maximum ratings table lists the DC switch voltage as -0.3 V - (Vsup + 0.3) V, regardless of operating condition. The chip is not qualified or designed to operate in the condition that you propose, even when the switch is OFF.
Your guess about ESD protection circuitry is probably a correct one - applying 12 V to the pin will cause the ...
If your design your external drivers to use the same 3.3V supply and have long traces or wires, you can reduce overshoot by adding 100R to the signal then the tiny ESD protection diodes rated for only a few mA limited by 10k resistors in two stages won't have to do any protection. But if the chip after ESD diodes gets > 1 Sh. diode drop above rail, then ...
The real purpose of the temperature sensor is to prevent damage to the chip and to make sure software running on the chip run correctly. All other uses are side-effects.
All electronics components have a maximum temperature before they start to fail. A high enough temperature will even damage a component (this is actually common sense, everything has a ...
A number of possibilities:
Marketing. It was inexpensive and could sell more MCUs; add it!
Technically possible, could be useful, inexpensive: why not?
Allows determining whether the system is within the intended operating range.
For higher-power devices, allows throttling the operating frequency.
For low-power devices, allows measuring (close to) the ...
There are a few things you can do:
Voltage reference and oscillator temperature correction.
Ambient temperature estimation, the kelvin per watt (k/w) temperature rise is reasonable stable over the entire range, so you can make a rough guess. If you don't jump into sleep modes that complicate the package power calculation.
The main objective of that sensor is to measure the temperature of the microcontroller itself when it is enclosed in the case of any equipment. It is used to check whether or not the IC is too hot either because of internal high temperature of case or may be because of high-power dissipation through microcontroller.
Moreover, it is not a reliable source for ...
Of course you can select fixed resistors instead of a potentiometer to make it non-adjustable.
The 79xx regulators are intended to be used as fixed regulators, but can be made adjustable, and the actual voltage of the regulator just sets the minimum voltage, it can be adjusted higher.
The output voltage term always includes the ground or adjust pin current, ...
I will assume that the reset operates on a high input here. If it's low to reset, just reverse high and low in the description below.
A reset signal could be edge-triggered, or not. If it's edge triggered, then the reset will happen when the MR goes from low to high, but then it will come out of reset, even if MR remains high.
By specifying that it's DC ...
Individual layers on a die provide specific things like power, wiring (often in only one direction) or transistors. For a component to exist on a single layer it would have to be composed only of power lines, only of unpowered transistors not connected by wires, etc.
Any complicated (or even not complicated) component of a CPU will use all or nearly all ...
I assume you're talking about a multi-core processor such as this one from Intel (source):
As is kind of evident from the picture, the CPU cores themselves have common logic that they all need access to. Such a component that pretty much all modern processors have is a level-3 (L3) cache ("Last Level Cache"/LLC in the picture). These connections ...
CPU cores have high trace count buses connecting them and their shared caches. They're physically arranged close to each other to keep those costly and power-hungry buses as short as possible. Distributing the cores widely across the die would make routing all of those connections harder while possibly making communication less efficient.
Generally speaking a Security or Cryptographic IC is an integrated device or SOC block which itself contains several security building blocks which implement standard cryptographic algorithms.
Some of these features require a higher order architecture to integrate into your system/application.
More and more manufacturers are providing further integration ...
I work in embedded security, but I don't know much about Arduino. So this is the "term I can browse and find" part of your question, w/o any Arduino-specific stuff.
MCUs these days, more and more, are shipping with security features like built in hash processsors, symmetric crypto accelerators (e.g. AES) and sometimes even public key acceleration (...
