SN8P1927

Description

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).
