SN8P2947 is a high-performance 8-bit microcontroller with the 2K-word of the OTP ROM.
The SN8P2947 provides the following features: 128 bytes of RAM, one 8-bit basic timer
(T0) function, a watchdog timer, 3-sources interrupts (INT0, T0, ADC), a in system
programming ROM (ISP ROM) function with VPP voltage generation internally, a 16-bit
ADC, a PGIA, a voltage regulator, a integrated R and C-Type LCD driver for 4-common
x 12 -segments LCD panel and a 8-level stack register. In addition, the SN8P2947 is
a dual clock system, i.e. high-speed system clock and low-speed system clock. The
high-speed system clock sources is generated from internal 4MHz high-speed RC oscillator
(IHRC 4MHz). The low-speed system clock is generated from on-chip low speed RC oscillator
circuit (ILRC [email protected]).
