Reset Circuit

The S-80845 IC Voltage Detector can detect the voltage while RC is charging. And outputs

the system reset signal of “LOW” when the driving voltage is lower than 4.5Vdc (Typical).

Memory Circuit

There are 2MB DRAM and 2MB Flash ROM built on the Main PC Board. This is the

memory circuit. The U6&U7 type 1M Byte Flash ROM and U8 type 2M Byte DRAM are

used. The MCU R/W pin becomes “H” when reading Flash ROM or DRAM, and “L” when

writing. JP6 is memory card connector, and it can expand to 8MB.
