>5ns pulse detection with mcu

Burak Güvelioglu

Can any Mcu detect a 5ns wide pulse? Is MCU clock speed important in this case? Or are MCU pin speeds important?

Are MCUs capable of detecting such a low amplitude signal?

Many thanks for any guidance provided...

Hi Burak,

In HRCAP mode, min pulse width is 110 ns. We do not have any MCU in C2000 device family which can measure 5ns pulse width.

TMS320F2838x device or TMS320F2837xD device can run at 200 MHz, and can measure 10ns pulse in regular eCAP mode.

Well, Can I measure 10ns pulse width?

Yes, with device running at 200 MHz (F2837xD, F2838x) using regular eCAP.
