FEATURES1. ROM: 1K x 14 bits MTP
2. RAM: 48 x 8 bits
3. STACK: 5 Levels
4. I/O Ports: Two bit-programmable I/O ports (Max. 6 pins)
5. Two Independent Timers
. Timer0
- 8-bit timer0 with divided by 1 ~ 256 pre-scale option / counter / interrupt / stop function
. T2
- 15-bit T2 with 4 interrupt interval time options
- IDLE mode wake-up timer or used as one simple 15-bit time base
- Clock source: Slow-clock (SIRC) or Fsys/128
6. One 8-bit PWM with pre-scale / period-adjustment / buffer-reload / interrupt / clear and hold function
7. Min. Operating Voltage (power on) and Speed: VDD can be lowest to 1.5V when the Fsys is 4 MHz
8. PA1 ~ PA4 individual pin low level wake up
9. System Oscillation Sources (Fsys)
. Fast-clock
- FIRC (Fast Internal RC): 1 MHz / 2 MHz / 4 MHz
. Slow-clock
- SIRC (Slow Internal RC)
VDD = 3V, SIRC = 110 KHz / 27.5 KHz / 6.88 KHz / 1.72 KHz
10. Power Saving Operation Modes
. FAST Mode: Slow-clock can be disabled or enabled, Fast-clock keeps CPU running
. SLOW Mode: Fast-clock stops, Slow-clock keeps CPU running
. IDLE Mode: Fast-clock and CPU stop. Slow-clock, T2 or Wake-up Timer keep running
. STOP Mode: All Clocks stop, T2 and Wake-up Timer stop
11. Dual System Clock
. FIRC + SIRC
