Panasonic KX-FT63BX

6.3.2. ASIC (IC1)
This custom IC is used for general FAX operations.
1. CPU
This model uses a Z80 equivalent CPU operating at 6MHz.
Many of the peripheral functions are handled by custom designed LSIs. As a result, the CPU only needs to process the result.
2. RTC
Real time clock.
3. DECODER
Decodes the address.
4. ROM/RAM I/F
Controls the SELECT signal of ROM or RAM and bank switching.
5. CIS I/F
Controls document reading.
6. IMAGE DATA RAM
This is inside the ASIC and has 8KB which is used for image processing.
7. THERMAL HEAD I/F
Transmits the recorded data to the thermal head.
8. MOTOR I/F
Controls the motor which feeds the document and feeds the reading document.
9. OPERATION PANEL I/F
Control port for Operation Panel.
10. I/O PORT
I/O Port Interface (for analog board port control).
11. ANALOG BLOCK
Electronic volume for the handset and monitor.
Sends beep tones, etc.
