Infineon XMC4500 ARM Cortex-M4F Demo

The modular design kit for the XMC4500 series. Up to three additional application boards - for actuators and sensors (top), for human-machine interface (HMI) functions (right), and for communication with other systems (left) - can be connected to the basic design board with XMC4500 (middle), depending on the respective application requirements.

Infineon XMC4500 ARM Cortex-M4F Demo

This page documents a demo application that uses the FreeRTOS GCC ARM Cortex-M4F port. It targets the Infineon XMC4000 Hexagon Development Kit CPU board, which is populated with an XMC4500 microcontroller.

Infineon Technologies - Wikipedia

Infineon Technologies was founded in April 1999 when the semiconductor operations of parent company, Siemens AG, were spun off to form a separate entity.

LM335 - Precision Temperature Sensor

The LM135, LM235, LM335 are precision temperature sensors which can be easily calibrated. They operate as a 2-terminal Zener and the breakdown voltage is directly proportional to the absolute temperature at 10mV/°K.

LM335 - Precision Temperature Sensor

Precautions should be taken to ensure good sensing accuracy. As in the case of all temperatures sensors, self-heating can decrease accuracy. The LM135, LM235, and LM335 should operate with a low current but sufficient to drive the sensor and its calibration circuit to their maximum operating temperature.

LM335 - Precision Temperature Sensor

Above data from STMicro - Circuit shows a design using LM335 for Temperature Control.

LM335 Cold Junction Compensation

Temperature Sensors like Thermocouples need cold junction compensation as a part of front end signal conditioning, this is done at the terminal block where the Thermocouple wires are terminated. This design has to be more accurate and broad, if the design we make has to work well in both Tropical and Temperate Climate Zones.

Thermocouple Temperature using DPM or DMM

Temperature measurement and control uses the Thermocouple and the Seebeck Effect for measurement. The most common is J Type as it is affordable. K is better and works well even at higher temperatures too.

4-20mA Conditioning - XTR101 TI BB

These are Burr Brown Devices from TI. The BB Chips are excellent devices and High Precision, but a bit more expensive. These can be used when customer demands a Higher Quality and Precision. These are good for High Reliability Industrial Instrumentation. - delabs

4-20mA Conditioning - XTR101 TI BB

The XTR101 is a microcircuit, 4-20mA, two-wire transmitter containing a high accuracy instrumentation amplifier (IA), a voltage-controlled output current source, and dual-matched precision current reference.

4-20mA Conditioning - XTR101 TI BB

The two-wire transmitter allows signal and power to be supplied on a single wire pair by modulating the power-supply current with the input signal source. The transmitter is immune to voltage drops from long runs and noise from motors, relays, actuators, switches, transformers, and industrial equipment.
