Temperature Measurement with PSoC CY8C27643 and DS18B20 sensor is based on PSoC Express.
Since PSoC Express has been obsoleted, I request you to kindly use AN2163 - Interfacing to 1-Wire/Two-Wire Digital Temperature Sensors using PSoC® 1. This Application Note uses two GPIOs of PSoC to interface with the Dallas 1-wire sensor DS18X20.
Best regards,
