I am using Internal RTC of LPC1768 but is lagging by 4 & half minutes for 1 hour. Is there any solution to make it accurate or this is the problem of LPC1768 internal RTC?
Which silicon revision is your MCU? Please notice that Revision A does not suffer from the RTC.1 erratum. The RTC oscillator is expected to work fine on rev A silicon.
Hope it helps!

The LPC176x devices typically have the following top-side marking:
The last/second to last letter in the third line (field ‘R’) will identify the device revision.
there is "LPC1768FBD100
so it is revision A?
