Using the API DieTemperature on PSOC5 (CY8C5588AX*-060) returns a temperature with an offset of app. -42Deg. E.g. the Chip has 25°C, the funktion returns -17°C. Anyone to help me ? The API returns no Error.

I've found the same issue - die @ about 30C reading -10. The temperature does go up when the chip is warmed so it may just be a offset error.

 Hi all,

Please refer to the PSoC5 ES1 Silicon Errata document over here - http://www.cypress.com/?rID=43758

According to the Errata No - 2, Temperature sensor is not factory trimmed. That is why you are getting a very big variations in the output. This fix will be available in ES2.

Regards,

Kishore.
