Errata Summary
The following table defines the errata applicability to available CY8CTxx120 family devices.
[1]. Internal Main Oscillator
(IMO) tolerance deviation at
temperature extremes
[2]. The DP line of the USB
interface may pulse low when
the PSoC device wakes from
sleep, causing an unexpected
wakeup of the host computer
[3]. Invalid Flash reads may
occur if Vdd is pulled to -0.5V
just before power on
[4]. PMA Index Register fails
to auto increment with
CPU_Clock set to SysClk/1
(24 MHz)
