With regards to internal functions, the device includes 16K words of Flash Program Memory, 1024 bytes of Data Memory and 256 bytes of True EEPROM Memory. The device’s internal integrated Infrared Thermometer circuit, which includes an OPA, a 24-bit Delta Sigma A/D converter and an LDO, can reduce the external component requirements thus reducing the product size. The internal LCD driver has a boost voltage circuit and a voltage stabilising function, which reduces the effect on LCD brightness due to drops in supply voltage. The device has a complete set of communication interfaces, including UART, I2C and SPI interface types, which can provide convenient communication with different devices. The true EEPROM can be used to store product automatic adjustments and calibration parameters, thus simplifying development and production.

With regard to packaging, the device is supplied in the same package types and pins as the BH67F2752, which are 48-pin and 64-pin LQFP package types, providing convenience and flexibility for customers who wish to develop different grade series products.
