BH66F5242 has built-in LED drive function, LDO, OPA and 24-bit Delta Sigma A/D. In application, it can reduce external components and greatly reduce material cost and PCB complexity. In terms of system resources, BH66F5242 has 4Kx16 Flash Program Memory, 256x8 RAM, 64x8 True EEPROM, UART/SPI/I2C and Timer Module.
The built-in OPA can be configured as a constant current generator to drive an external sensor, which can improve the stability of the measurement and reduce the influence of temperature drift factors.
BH66F5242 offers 16-pin NSOP, 20-pin NSOP and 20-pin QFN three package types, and the small size package has a competitive price advantage.
The 8-inch tablet will have a big impact on the 7-inch and 10-inch tablet market. Because the portability of an 8-inch tablet is stronger than that of a 10-inch tablet, and the usable area is larger than that of a 7-inch tablet. The most important thing is that the price is more moderate, which is much cheaper than a 10-inch tablet. It can be said that the 8-inch tablet computer has a good balance between portability and screen display area, and is more likely to be favored by the majority of users.
