Part Number:MSP430FR2000
In our project, we wanna use wiegand sensor to count the times while it activated when system is out of power.
Wiegand sensor could generate a 10us width regulatered pluse after it activated, we wanna using this pluse to power the chip and read --> increase/decrease --> store the counter, and when the system is powered-on, other mcu could read the counter register from this chip.
So, we need fram to achieve this, and MSP430FR series already embeded fram, I wanna know is there exists a type of mcu in TI could achieve power on then do above procedure in 10us?
If you got some information, please let me know and thanks for your help.
