This series is utilized with CMOS technology fabrication and featured with low power consumption and high performance by its unique electronic structure.
These chips SN8P1708 are designed with the excellent IC structure including the large program memory OTP ROM, the massive data memory RAM, one 8-bit basic timer (T0), two 8-bit timer counters (TC0, TC1), a watchdog timer, up to seven interrupt sources (T0, TC0, TC1, SIO, INT0, INT1, INT2), a 7-bit DAC converter, an 8-channel ADC converter with 8-bit/12-bit resolution, two channel PWM output (PWM0, PWM1), tw0 channel buzzer output (BZ0, BZ1) and 8-level stack buffers. Besides, the user can choose desired oscillator configurations for the controller. There are four oscillator configurations to select for generating system clock, including High/Low Speed crystal, ceramic resonator or cost-saving RC. SN8P1708 series also includes an internal RC oscillator for slow mode controlled by programming.
