The EVAL-CN0221-EB1Z is an evaluation board described in the circuit from lab CN-0221, entitled "USB based temperature monitor using the ADuCM360 precision analog microcontroller and an external thermocouple". This circuit uses the ADuCM360/ADuCM361 precision analog microcontroller in an accurate thermocouple temperature monitoring application. The ADuCM360/ADuCM361 integrates dual 24bit sigma-delta (Σ-Δ) analog to digital converters (ADCs), dual programmable current sources, a 12bit digital to analog converter (DAC), and a 1.2V internal reference, as well as an ARM cortex-M3 core, 126KB flash, 8KB SRAM, and various digital peripherals such as UART, timers, SPIs, and I2C interfaces. In the circuit, the ADuCM360/ADuCM361 is connected to a thermocouple and a 100R platinum resistance temperature detector (RTD). The RTD is used for cold junction compensation.
