Hi,
I have 2 LPC1857 chips with different device revision:
1. ESD14440- (initial device revision)
2. ESD16030A (second device revision)
I noticed that there is a different between the 2 device revision whereby when both are put into DeepPowerDown low power mode, the nRESET button would wake the ESD14440- up but not the ESD16030A. My workaround now is to use the event router bit 19 to detect low level of RESET_SETEN to wake the chip up (ESD16030A).
What has changed between the 2 device revisions? Is there an errata to explain the differences between the 2 device revisions?
