Hi does anyone know if there is a philips micro (8051), which will work at a voltage level below 2.7 Volts...maybe 1.5V? Currently I am using the LPC932A1, but with the Brown Out Detection peripheral the mcu stops working at a voltage of 3.2 Volts. When I say it stops working I mean it enters the ISR interrupt 5 (BOD) and executes the code in it. I thougth with the (BOD) peripheral the micro could work/execute down to 2.7V. Why would it be entering BOD at 3.2 Volts instead...are there any tolerances?
I had checked these results with 2 AA batteries and with a power supply. Is there any way to force it to enter BOD at 2.7Volts and not at 3.2V? Erik I believe you can help me here.

Thank you,

Caleno
