Level Translator Simm Card
NVT4555
The NVT4555 device is built for interfacing a SIM card with a single low-voltage host side interface. The NVT4555 contains an LDO that can deliver two different voltages, 1.8 V or 2.95 V from typical mobile phone battery voltages up to 5.25 V and three level translators to convert the data, RSTn and CLKn signals between a SIM card and a host microcontroller.

Temp Sensor
PCT2075
The PCT2075 is a temperature-to-digital converter featuring ±1 °C accuracy over ‑25 °C to +100 °C range. It uses an on-chip band gap temperature sensor and Sigma-Delta A‑to‑D conversion technique with an overtemperature detection output that is a drop-in replacement for other LM75 series thermal sensors. The device contains a number of data registers: Configuration register (Conf) to store the device settings such as device operation mode, OS operation mode, OS polarity and OS fault queue; temperature register (Temp) to store the digital temp reading, set-point registers (Tos and Thyst) to store programmable overtemperature shutdown and hysteresis limits, and programmable temperature sensor sampling time Tidle, that can be communicated by a controller via the 2-wire serial I²C-bus Fast-mode Plus interface.
