What is eFuse in IC?
eFuse IC (electronic fuse) controls the on and off of the power supply by built-in MOSFETs, that solves the disadvantages of conventional fuses. It can be used in the same way as a conventional fuse, and has variety of built-in protection functions by taking advantage of the fact that it is a semiconductor.
Is eFuse real?
In computing, an eFuse (electronic fuse) is a microscopic fuse put into a computer chip. This technology was invented by IBM to allow for the dynamic real-time reprogramming of chips. By utilizing a set of eFuses, a chip manufacturer can allow for the circuits on a chip to change while it is in operation. …
What does an eFuse do?
An eFuse is an “active circuit protection device with an integrated FET used to limit currents, voltages to safe levels during fault conditions”. It embeds various functions to protect system against inrush current, overcurrent, overvoltage, reverse current, reverse polarity and short circuit faults.
What is eFuse memory?
Electrically Programmable Fuse (eFUSE): From Memory Redundancy to Autonomic Chips. Abstract: Electrical fuse (eFUSE) has become a popular choice to enable memory redundancy, chip identification and authentication, analog device trimming, and other applications.
What is eFuse in ESP32?
The ESP32 has a number of eFuses which can store system and user parameters. Each eFuse is a one-bit field which can be programmed to 1 after which it cannot be reverted back to 0. Some of system parameters are using these eFuse bits directly by hardware modules and have special place (for example EFUSE_BLK0).
How do you eFuse HP blade server?
To eFUSE server reset the server blade, perform the following:
- SSH to OA.
- Enter below command. (X is server bay number.) > reset server X.
- Type ‘YES’ when confirmation popup.
- The server will reboot several times during the Power-On Self-Test (POST) to reapply VC settings.
Is eFuse safe?
The Texas Instruments (TI) Power Switches portfolio provides multiple options for safety- certified devices. Specifically, TI’s electronic fuses (eFuses) portfolio are robust power path protection devices that are UL 2367 Recognized and IEC 62368- 1 Certified.
Who owns eFuse?

How do you do eFuse?
To perform an e-fuse reset:
- Telnet to OA IP Address.
- Login to Onboard Administrator with Administrator privileges using the OA CLI.
- Enter the command RESET SERVER X where [X = bay number].
- Confirm that the user wants to reset the server blade.
What is eFuse OTP?
One-time programmable (OTP) memory is a type of non-volatile memory (NVM) that commonly comprises of electrical fuse (eFuse) and antifuse. In contrast, an eFuse is programmed by electrically blowing a strip of metal or poly with a flow of high-density current using I/O voltage.
What is eFuse gaming?
eFuse is a web and mobile application that provides validated opportunities and candidates for the esports and Video Game industry. Website http://efuse.gg. Industries Internet Publishing.
How do I find my MAC address ESP32?
uint8_t newMACAddress[] = {0x32, 0xAE, 0xA4, 0x07, 0x0D, 0x66}; After uploading the code, open the Serial Monitor at a baud rate of 115200. Restart the ESP32 and you should get its old and new MAC Address.
What is an eFUSE IP core?
An eFuse IP core has the ability to detect and react to irregular voltage and current influxes in very rapid time, reverting the value back to the safe range that has been determined beforehand by the user. This function of the fuse allows the chip manufacturers to alter the performance of the chip while it is in operation.
What is an eFUSE and how does it work?
eFuse stands for electronic fuse. Developed by IBM in the early 2000s, the purpose of an eFuse is to allow you to change and modify functions or performance of a chip and allow designer to tune it to perform better. Normally, it is not possible to alter chip hardware because the design or logic of the chip is etched onto the chip permanently.
What is the function of an eFUSE in a chip?
This function of the fuse allows the chip manufacturers to alter the performance of the chip while it is in operation. If a particular subsystem of the chip is not performing the way it is supposed to or is consuming too much power, it can be disconnected from the rest of the chip by simply blowing out the connecting eFuse.
How many bits of fuses are there in an eFUSE?
TI FPD-Link SERDES for a variety of different settings. eFuses known to be used for hardware restriction : IBM/Microsoft Xenon CPU in the Xbox 360 game console. 768 bits of fuses. NVidia Tegra X1 SoC used in the Nintendo Switch hybrid video game console. 256 bits of reserved fuse.
