BL0938
Multi-rate control IC
Summarization BL0938 is a kind of 8-bit micro-control unit, which is high-performance and low-power, specially for power meter circuit. It is made with CMOS process, including 4K Byte user ROM and 196K Byte user RAM. It has many merits, such as low-power, high-integrated level, high reliability and etc. It also has high-stability real-time clock and hardware watchdog inside the chip. A serial port is included to meet the needs of infrared and gathering meter-record communication. While applying to infrared mode, a 38K modulated wave is produced inside the chip. Serial port RXD and TXD can be used to communicate with wire-carried wave in low voltage system, or make up gathering meter-record system by 485 port.
