[1]. Internal Main Oscillator (IMO) Tolerance Deviation at Temperature Extremes
1. Internal Main Oscillator (IMO) Tolerance Deviation at Temperature Extremes
PROBLEM DEFINITION
Asynchronous Digital Communications Interfaces may fail framing beyond 0 to 70°C. This problem does not affect end-product usage between 0 and 70°C.
PARAMETERS AFFECTED
The IMO frequency tolerance. The worst case deviation when operated below 0°C and above +70°C and within the upper and lower datasheet temperature range is ±5%.

TRIGGER CONDITION(S)
The asynchronous Rx/Tx clock source IMO frequency tolerance may deviate beyond the data sheet limit of ±2.5% when operated beyond the temperature range of 0 to +70°C.
SCOPE OF IMPACT
This problem may affect UART, IrDA, and FSK implementations.
WORKAROUND
Implement a quartz crystal stabilized clock source on at least one end of the asynchronous digital communications interface.
FIX STATUS
The cause of this problem and its solution has been identified. Silicon fix is planned to correct the deficiency in silicon.
