BH67F2265
R-Type Blood Pressure Meter Flash MCU with LCD
The device is a Flash Memory A/D type 8-bit high performance RISC architecture microcontroller with LCD driver, specifically designed for Blood Pressure Meter applications.
For memory features, the Flash Memory offers users the convenience of Flash Memory multiprogramming 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. By using the In Application Programming technology, user have a convenient means to directly store their measured data in the Flash Program Memory as well as having the ability to easily update their application programs.
Analog features include a multi-channel 12-bit A/D converter, PGA and OPA functions. 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 intergrated SPI, UART or I²C interface functions, three popular interfaces which provide designers with a means of easy communication with external peripheral hardware. In addition, an internal LDO function provides power to the internal modules and external devices. 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 external low, internal high and low oscillators is provided including two 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 optimize microcontroller operation and minimize power consumption.
The inclusion of flexible I/O programming features, a fully integrated LCD driver and Time Base funcitons along with many other features enhance the versatility of the device to enable quick and cost efficient Blood Pressure Meter applications.
