| Abstract: | The nonvolatile data memory, real-time clock, and watchdog functions of FM31256 chip were adopted by region fire alarm and control device to improve the system reliability. The ferroelectric technology was used by FM31256 chip. The storage area of chip could be divided into system sign, physical coding of detector, logical coding of detector, detector sign and alarming record area. The 89C52 chip was adopted by system MCU. The 89C52 chip was connected with SCL and SDA in FM31526 through pins. And the I2C bus protocol was also adopted to realize the data exchange between single chip and FM31256. |
