• Manufacturer Part Number: w925e625
• Description: 8-bit Cid Microcontroller
• Manufacturer: ETC-unknow

Note: ”CPE*” Customer Premises Equipment
I/O: 40 I/O pins.
Power mode:
Timer: 2 13/16-bit timers, or 8-bit auto-reload timers, that are Timer0 and Timer1.
Watchdog timer: WDT can be programmed by the user to serve as a system monitor.
Interrupt: 11 interrupt sources with two levels of priority.
Divider: 13/14 bit divider, clock source from sub-oscillator, therefore, DIVF set every 0.25/0.5 Sec.
Comparator:
Serial port:

DTMF generator/receiver;
Ring detector: for line reversal for BT, ring burst for CCA or ring signal for Bellcore.
Two independent OP amps with adjustable gain for Tip/Ring and Telephone Hybrid
connections.
P0: Bit and byte addressable. I/O mode can be bit controlled. Open drain type.
P1~P3: Bit and byte addressable. Pull high and I/O mode can be bit controlled.
P4 : Byte addressable. Pull high and I/O mode can be bit controlled.
Normal mode: Normal operation
Dual-clock slow operation mode: System is operated by the sub-oscillator (Fosc=Fs and Fm
is stopped)
Idle mode: CPU hold. The clock to the CPU is halted, but the interrupt, timer and watchdog
timer block work normally but CID function is disabled.
Power down mode: All activity is completely stopped and power consumption is less than 1
4 interrupts from INT0, INT1, INT2 and INT3.
2 interrupts from Timer0, Timer1.
1 interrupt from Serial port.
1 interrupt from CID.
1 interrupt from 13/14-bit Divider.
1 interrupt from Comparator.
1 interrupt from Watch Dog Timer.
Comparator:1 analog input from VNEG pin, 2 reference input pins, one is from VPOS pin and
another is from internal 1.0v regulator output.
An 8-bit serial transceiver with SCLK and SDATA.
