POR & Brown-Out Reset Voltage Levels
EPM1270 devices have POR circuits to monitor V
levels during power-up. The POR circuit monitors these voltages
triggering download from the non-volatile configuration flash memory
(CFM) block to the SRAM logic maintaining tri-state of the I/O pins
before and during this process. When the EPM1270 device enters user
mode, the POR circuit releases the I/O pins to user functionality and
continues to monitor the V
brown-out condition. If there is a V
operational level during user mode, the POR circuit resets the device and
re-triggers an SRAM download. For EPM1270 ES devices, the POR re-
trigger voltage level for a V
high as 2.1 V, allowing for 275 mV of V
minimum. EPM1270 ES device users should ensure that the power
supply noise does not lead V
