Cypress CY8C22x13 Errata Document, References, Trigger Conditions, Scope Of Impact, Workaround

Errata Document CY8C22x13

■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.
