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.
