SN8P2988 is a high-performance 8-bit microcontroller with the 16K-word of the OTP
ROM. The SN8P2988 provides the following features: 1Kbytes of RAM, one 8-bit basic
timer (T0) with RTC function, three 16-bit timers/counters (TC0~2), a watchdog timer,
Eleven-sources interrupts (INT0, INT1, T0, TC0~2, ADC1, ADC2, I2C, UART0/1), a in
system programming ROM (ISP ROM) function with VPP voltage generation internally,
two DAC, two OPA, a 20-bit DS-ADC, a 12-bit SAR-ADC , a PGIA, a voltage regulator,
a integrated R and C-Type LCD driver for 4/6-common x 36/34-segments LCD panel and
a 8-level stack register. In addition, the SN8P2988 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.
