7-3-1 Outline
The main micom peripheral circuit is composed of 16bit Micom(MIC1,TMP93CS41), 2M PROM (MIC2,AM27C020
for Microcode and data save, 1M SRAM(MIC3, KM681000) for data read/write on running, 512 byte EEPROM
(MIC5, IS24C02)for permanent storage of data needed at power off, MIC4(74AC573) to latch only address in the
bus where address and data are mixed, address decoder (MIC6, 74HC00) for selection of external device chip and
20MHz clock oscillator for micom operation. The micom(MIC1, TMP93CS41) mounted in main board analizes the
key commands of front panel or instructions of remote control through communication with micom(FIC1,
LC86P6232) of front and controls the devices on board to execute the corresponding commands after initializing the
devices connected with micom on board at power on.
