With regards to MCU resources, the BH66F71662/BH66F71652 devices include a Flash Program Memory capacity of 16K×16/8K×16, a Data Memory capacity of 512×8/384×8, an EEPROM capacity of 64×8/32×8, LED driver and various communication interfaces. The devices include an integrated Bluetooth transmission circuit which can easily implement Bluetooth Beacon transmission functions, thus simplifying product development and production. T

he devices have a fully integrated four-electrode AC body fat circuit which use AC body fat measurement technology to implement more accurate impedance measurements and also greatly reduce the external component requirements. This results in major reductions in BOM costs as well as improved productivity. The internal 24-bit A/D Converter circuit together with the internal LDO can provide power to external sensors for weight measurement purposes.

As for packaging, the devices are supplied in 46-pin QFN package types. With their abundant system resources and comprehensive range of functions, the devices can meet the needs of a wide range of diversified health measurement products.
