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. 16 I/O ports
can give users support of multi-path data processing function, or be used as
general I/O ports. The ability of resisting electromagnetic interference and
radiation is powerful: ESD 4000V; fast pulse group 4000V. BL0938 and
BL2220R3, a 8-bit micro controller of Belling, are compatible in command
system. BL0938 is mostly used in multi-function power meter (including
multi-rate, advance payment and gathering meter-record system) and other
plug-in civil or industrial control system.

Feature
Low power: asynchronous static chip design method, support STOP, WAIT power-save mode.
8-bit timer, with 7-bit pre-position.
Double crystal vibration circuit inside chip. 4MHz, used as timer of local system bus. 32.768KHz,
used as timer at the real time.

Two ways,8 I/O port in each (high-impedance as power-on, input mode). Each port has
programmable pull-on resistor. Current in I/O port can drive standard TTL.
Hardware watchdog including.
8 interrupt sources: timer, software, outside, RTC, UART, low voltage, keyboard, watchdog.
One UART serial communication port.
Programmable real timer RTC, one or ten seconds interrupt can be produce.
Standard 5V working voltage. Supply RTC by 3.3V backup battery as power down.
Kinds of reset function: low voltage, electrify, reset pin, watchdog.
