W925E/C240
8-bit CID Microcontroller
Revision : A6
-4-
Release Date : 2002/7/2
Power mode
:
- 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
μ
A.
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.
- 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.
Divider:
13/14 bit divider, clock source from sub-oscillator, therefore, DIVF set every 0.25/0.5
second.
Comparator:
- Comparator: 1 analog inputs from VNEG pin, 2 reference input pins, one is from VPOS
pin and another is from internal regulator output.
Serial port:
- An 8-bit serial transceiver with SCLK and SDATA.
.
Package:
- 100pin QFP
