Inheriting the excellent feature of the BH67F2132, this new BH67F2142 has a richer set of MCU resources and a minimum operating voltage of 1.1V, making it suitable for a wide range of single-battery powered temperature measurement products, such as thermometers and indoor/outdoor temperature measurement applications.
The BH67F2142 includes an integrated resistance/frequency (R/F) conversion circuit and an EL backlight function. In having a high level of functional integration, the device requires few peripheral components, which significantly reduces manufacturing costs. The device has an integrated Flash program memory and Data EEPROM which can store various parameters and increase the product flexibility.
The device includes 4K words of Flash Program Memory, 256 bytes of Data Memory and 128 bytes of EEPROM Memory. As for packaging, the device is supplied in a 48-pin LQFP package type.
