Demonstration Module Texas Instruments AFE4110DPENEVM
The AFE4110 Demo Pen demonstrates an accurate low-cost single-chip temperature measurement solution based on the AFE4110.
Detailed Description
This device is a general-purpose low-cost 1.5V microcontroller optimized for the temperature measurement application with features like an internal 1.85V/3.3V charge-pump for LCD/GPIO interface, buzzer driver and ultra low power sleep mode. The termperature measurement is done using an external thermistor with a negative temperature coefficient (NTC) characteristic (resistance decreases with increasing temperature). The thermistor response has been calibrated using two temperature points (at 31 degrees Celcius and 43 degrees celcius), for an overall typical accuracy of +/-0.1 ºC over that range, when measured in a calibration bath. The system has not been designed to measure human body temperature and should not be used for health diagnosis purposes.
Features
- Low cost single chip temperature measurement solution
- Performance and low cost: New, lowest price point for an MSP430 16-bit MCU with integrated LCD. The AFE4110 offers designers greater capabilities packaged into one low-cost device.
- Ultra-low power: Operating on a 1.5-V supply, the AFE4110 draws a low active current of 50 uA/MHz and sleep mode current of less than 0.3 uA.
- Reduced system cost: The low-cost AFE4110 has an integrated LCD and highly accurate oscillator, eliminating the need for an external crystal. In addition, the AFE4110 operates on a single, low-cost 1.5-V battery.
- MSP430 core: Leverages the large ecosystem of tools and sample code to speed designs.
- Overall typical calibrated accuracy of +/- 0.1 ºC over the temperature range of 31 ºC and 43 ºC
- Piezo-buzzer and LCD for audio-visual display
- Operates on a 1.5V coin cell battery
