Kit Overview

The AFE4110AFE4110 Demo Pen (AFE4110DPENEVMAFE4110DPENEVM) demonstrates an accurate low-cost single-chip temperature measurement solution based on the AFE4110AFE4110. 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.

The AFE4110AFE4110 CPU architecture is based on the popular ultra low power Texas Instruments MSP430 RISC processor.The AFE4110AFE4110 configuration with two 16-bit timers, integrated 48-segment LCD driver, programmable Analog Pool, supply voltage monitor and internal reference voltage source is particularly well suited for implementation of low cost digital thermometers operating from a single cell SR60 battery.

The capability to correct the on chip high frequency oscillator output facilitates the generation and measurement of real time intervals. For many applications, this capability allows system designers to eliminate a clock crystal from the system BOM.

Key applications: Any application requiring a full analog signal chain and an LCD display driver such as digital thermometers, pedometers, thermostats, and other portable single alkaline battery devices.
