IN9004-1
IN9004D - INTEGRATED MICROCHIP MICRO-CONTROLLER WITH
MCS-51 SYSTEM OF COMMANDS, SUPERVISORS CIRCUIT AND
EMBEDDED LCD DRIVER FOR APPLICATION IN ENERGY METERS
The microchip is essentially the high efficiency micro-controller, made under the high
fidelity CMOS – technology.
The microchip contains the programs ROM with the capacity of 4,096 bytes, the
embedded data RAM with the capacity of 128 bytes, 32 input/output lines, two 16-bit
timers / counters, guard timer, interrupts system with five vectors and two priority levels,
the serial port for expansion of input/output as the universal asynchronous transceiver, the
embedded synchro generator and synchronization system, the embedded driver for the
LC- display control (number of segments -124, duty rate - 1:4, frame frequency - 50-300
Hz, the LCD operational - voltage 3.6 V).
The micro-controller system of commands complies with the system of commands of
the MCS-51 family. The microchip is initialized (reset) automatically when turning power
on, when the guard timer is overflowed or effected by the RST signal (voltage active low
level) if the external synchronization signal is applied or during the quartz connection.
The LCD control micro-controller microchip with the MCS-51 system of commands
can be successfully applied as the processor element in the electronic power counters.
The microchip has two programmable modes for the reduced power consumption,
the idle mode and the micro-consumption mode. The idle run mode locks the central
processor’s operation, stores the condition of the internal ROM data, the timers,
consecutive port, LCD control unit and the discontinuity system keep on functioning. The
micro-consumption mode turns off the specifying generator, operation of all assemblies of
the microchip stops and the ROM data contents is kept in storage.
