Detailed Description

The BA45F5440 is a Flash Memory A/D type 8-bit high performance RISC architecture microcontroller, designed especially for high voltage smoke detector applications which also require a buzzer alarm function.

For memory features, the Flash Memory offers users the convenience of multi-programming 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.

Analog features include a multi-channel Analog to Digital converter, two operational amplifiers and an internal TinyPower LDO which allows input voltages as high as 12V and provides a fixed 3.3V voltage. With regard to internal timers, the device includes multiple and extremely flexible Timer Modules providing functions for timing, pulse generation and PWM output operations. Communication with the outside world is catered for by including fully integrated SPI, I2C and UART interface functions, three popular interfaces which provide designers with a means of easy communication with external peripheral hardware. Protective features such as an internal Watchdog Timer, Low Voltage Reset and Low Voltage Detector coupled with excellent noise immunity and ESD protection ensure that reliable operation is maintained in hostile electrical environments.
