. M5610: 1uA @VDD=1.5V, VBAT=3V, with power saving
. M5615: 1.5uA @VDD=1.5V, VBAT=1.5V
3. Program ROM: 1K x 14 bits MTP (Multi Time Programmable ROM)
4. RAM: 96 x 8 bits
5. STACK: 5 Levels
6. I/O ports: Maximum 12 programmable I/O pins
. Open-Drain Output
. CMOS Push-Pull Output
. Schmitt Trigger Input with pull-up resistor option
7. System Oscillation Sources (Fsys) :
. Fast-clock
- FIRC (Fast Internal RC) : 3.8MHz @VDD=3V; 1.3MHz @VDD=1.5V
. Slow-clock
- SIRC (Slow Internal RC) : 80KHz @VDD=3V; 40KHz @VDD=1.5V
- SXT (Slow Crystal) : 32768 Hz
. System Oscillation Sources can be divided by 1/2/4/8 as System Clock (Fsys)
. Dual System Clock Switching between Fast-clock and Slow-clock
- FIRC + SIRC
- FIRC + SXT
8. Power Saving Operation Mode
. FAST Mode: CPU running at Fast-clock
. SLOW Mode: Fast-clock stop, CPU running at Slow-clock
. IDLE Mode: Fast-clock and CPU stop; Slow-clock, Timer2 and LCD keep running
. STOP Mode: All clocks stop
9. Resistance to Frequency Converter (RFC)
10. Two Independent Timers
. Timer0 (TM0)
- 8-bit timer with divided by 1~256 pre-scale option, reload/interrupt/stop function
- Clock sources: Fsys or Slow-clock /16 (SIRC/SXT)
. Timer2 (T2)
- 21-bit timer with 4 interrupt time period options (60s/1s/0.5s/0.125s)
- Clock sources: Fsys /128 or Slow-clock (SIRC/SXT)
- IDLE mode wake-up, if clock source is Slow-clock
11. Interrupts
. Three External Interrupt pins (INT0~INT2)
- Rising or falling edge triggered interrupt
- Wake-up CPU from IDLE/STOP mode
. Timer0/Timer2 Interrupts
. RFC overflow Interrupt

. Watchdog Reset
. Low Voltage Reset: M5610=1.7V, M5615=1.25V (LVR can be disabled by LVROFF after power on)
. External Pin Reset
16. Low Battery Detector (LBD) by BandGap Voltage Reference
