Holtek announced the release of a new 24-bit Delta Sigma A/D Flash MCU, the BH67F5270. The device has large memory capacity and excellent anti-RF interference, making it very suitable for use in 24-bit A/D high-precision measurement applications, such as those for weight, pressure and temperature measurements. These features make the new device an excellent choice for product applications such as electronic scales, blood pressure meters, blood glucose meters, pressure switches and other measuring type products.
The device includes a fully integrated LED driver, LCD driver, Operational Amplifier, LDO, PGA and a 24-bit Delta Sigma A/D Converter. With this high level of functional integration, the required number of external components is greatly reduced which will result in reduced manufacturing costs and improved productivity.
The device includes 32K words of Flash Program Memory, 2048 bytes of Data Memory, 512 bytes of True EEPROM Memory, a Multiplication Division Unit, an In-Application Programing function and Timer Modules. The device also provides multiple external serial interfaces, including UART, SPI and I2C interface types. The BH67F5270 is supplied in both 64-pin and 80-pin LQFP package types.
