SN8P1919

Description

SN8P1919 is a high-performance 8-bit microcontroller with the 6K-word of the OTP ROM. The SN8P1919 provides the following features: 256 bytes of RAM, one 8-bit basic timer (T0) with RTC (Real Time Clock) function, two 8-bit timer counters (TC0, TC1), a watchdog timer, five interrupt sources (T0, TC0, TC1, INT0, INT1), a 16-bit ADC, a PGIA, a charge pump/regulator, a integrated LCD driver for 4-common x 32-segments LCD panel and a 8-level stack register. In addition, the SN8P1919 is a dual clock system, i.e. there are high-speed clock and low-speed clock. The high-speed clock is generated from the external 4MHz oscillator or on-chip 4MHz high-speed RC oscillator circuit. The low-speed clock is generated from LXIN/LXOUT by 32768 crystal or RC oscillator circuit, and as a clock source for slow mode, real time clock and LCD function.
