SN8P1927 is a high-performance 8-bit microcontroller with the 2K-word of the OTP ROM.
The SN8P1927 provides the following features: 128 bytes of RAM, a 8-bit basic timer
(T0), a watchdog timer, 2-sources interrupts (T0, INT0), a in system programming ROM
(ISP ROM) register, a 16-bit ADC, a PGIA, a charge pump/regulator, a integrated LCD
driver for 4-common x 12 -segments LCD panel and a 8-level stack register. In addition,
the SN8P1927 is a dual clock system, i.e. high-speed system
clock and low-speed system clock. The high-speed system clock sources are generated
from the external oscillator which includes three modules (Crystal/Ceramic, RC and
external clock signal), or on-chip 16MHz high-speed RC oscillator (IHRC 16MHZ). The
low-speed system clock is generated from on-chip low speed RC oscillator circuit (ILRC
16KHz@3v, 32KHz@5v).
