CY8C22x13 Errata Summary

The following table defines the errata applicability to available CY8C22x13 family devices. An "X" indicates that the

errata pertains to the selected device.

Note Errata items, in the table below, are hyperlinked. Click on any item entry to jump to its description.

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.
