SN8F29E39 is a high-performance 8-bit microcontroller with the 32K-word of the Flash
ROM. The SN8F29E39 provides the following features: 6K bytes of RAM, one 8-bit basic
timer (T0) with RTC function, two 16-bit timers/counters (TC0/TC1), a watchdog timer,
night-sources interrupts (INT0, INT1,T0, TC0,TC1, ADC, UART,MSP), a in system programming
flash ROM function, a 20-bit ADC, a PGIA,12 bit DAC,4 output LED driver,2 OP-Amps,
a voltage regulator, a integrated C-Type LCD driver for 4-common * 32-segments LCD
panel or 6-common * 30-segments, and 16-level stack register. In addition, the SN8F29E39
is a dual clock system, i.e. high-speed system clock and low-speed system clock. The
high-speed system clock source is generated from internal 8MHz high-speed RC oscillator
(IHRC 8MHz). The low-speed system clock is generated from on-chip low speed RC oscillator
circuit (ILRC [email protected]) or external 32768Hz crystal@ IHRC_RTC.
