The BH67F2132 is a Flash Memory type 8-bit high performance RISC architecture microcontroller specially designed for very low voltage especially one battery applications. Offering users the convenience of Flash Memory multi-programming features, this device also includes a wide range of functions and features. Other memory includes an area of RAM Data Memory as well as an area of true EEPROM memory for storage of non-volatile data such as serial numbers, calibration data etc.

The advantages of low operating voltage, low power consumption, I/O flexibility, timer functions, oscillator options, R to F converter, LCD driver, Power down and wake-up functions, watchdog timer, as well as affordable feature, enhance the versatility of this device to suit for the one battery applications.

Analog features include a multi-channel 24-bit Delta Sigma A/D converter, three 12-bit D/A converters and three internal operational amplifiers. Multiple and extremely flexible Timer Modules provide timing, pulse generation and PWM generation functions. Communication with the outside world is catered for by including fully integrated SPI and UART interface functions, two popular interfaces which provide designers with a means of easy comminucation with external peripheral hardware. Protective features such as an internal Watchdog Timer and Low Voltage Reset coupled with excellent noise immunity and ESD protection ensure that reliable operation is maintained in hostile electrical environments.

A full choice of internal high and low oscillator functions are provided including three fully integrated system oscillators which require no external components for their implementation. The ability to operate and switch dynamically between a range of operating modes using different clock sources gives users the ability to optimise microcontroller operation and minimise power consumption.

With regard to CGM applications, the device has integrated many of the functions required by these products. These include functions such as Internal Reference Voltage generator, 24-bit Delta Sigma A/D converter, 12-bit D/A Converters and operational amplifiers, etc. The inclusion of flexible I/O programming features, 16-bit Cyclic Redundancy Check function, Time Base functions along with many other features enhance the versatility of the device to suit for CGM applications.
