Memory configuration
Fcpu (Instruction cycle)
ROM size: 4K * 16 bits.
Fcpu = Fosc/1, Fpsc/2, Fosc/4, Fosc/8, Fosc/16.
RAM size: 128 * 8 bits.
One 8-bit basic timer. (T0).
8 levels stack buffer.
One 8-bit timer/counter (TC0) with duty/cycle
5 interrupt sources
programmable PWM and IR carry signal.
3 internal interrupts: T0, TC0, T1
One 16-bit timer/counter (T1) with auto-reload/
2 external interrupt: INT0, INT1
counter/capture timer supports for RFC function.
5-Channel RFC (Resistor to Frequency Converter)
I/O pin configuration
4*32 LCD Driver (128 dots) supports internal C type
Bi-directional: P0, P1, P5.
and external R type bias.
Bi-directional and shared with SEG pins: P2, P3.
On chip watchdog timer and clock source is
Input only shared with reset pin: P0.3.
Internal low clock RC type (16KHz @3V, 32KHz
Wakeup: P0, P1 level change.
@5V).
