TMS320F2811: DSP

Part Number: TMS320F2811

Tool/software:

Dear Community 

The DSP 2811 seems to be extremly sensitive, after the 3,3v  Power Supply wire was accidentelly shorted to GND the microcontroller is broken ,it is not a first 2811 who died doring the tests ,most microcontrollers doesn’t have the issue with shorted Power to ground, can anyone explain why? 

Regards Sascha

    Hello,

    There are several reasons why the TMS320F2811 might be more sensitive to power supply shorts than other microcontrollers:

    • Low-voltage design: The TMS320F2811 is designed to operate at a low voltage of 1.8V to 3.6V, which makes it more susceptible to voltage spikes and shorts. Lower voltage designs often have less margin for error and can be more sensitive to power supply disturbances.
    • High-speed digital design: The TMS320F2811 is a high-performance DSP with a clock speed of up to 150 MHz. High-speed digital designs can be more sensitive to power supply noise and voltage spikes, which can cause glitches and damage to the device.
    • Analog and digital circuitry: The TMS320F2811 has both analog and digital circuitry on the same chip, which can make it more sensitive to power supply and input/output conditions. Analog circuits can be particularly sensitive to voltage spikes and noise.

    Thank you Stevan, next time i have to be very carefull since i destroyed two DSP,s the main problem is i have to wait till the New DSP is delivered then i have to solder and Programm New one
