sn8p2711a描述
The sn8p2711aA is a RISC-like high performance and low power c***umption 8-bit micro-controller. One clock per instruction cycle (1T) architecture will provide up to 16MIPS computation power. Also, the high EFT (Electrical Fast Transients) protection capability let this device is suitable for high noisy industrial application. The device is designed with the excellent IC structure including the program memory up to 1K-word OTP ROM, data memory of 64-bytes RAM, two 8-bit timer counters (TC0, TC1), a watchdog timer, five interrupt sources (TC0, TC1, ADC, INT0, INT1), an 5+1 channel 12-bit ADC converter (one internal ADC channel for VDD measurement), two channels PWM output (PWM0, PWM1), two channels buzzer output (BZ0, BZ1) and 4-level stack buffers. There are four oscillator configurati*** to select for generating system clock, including High/Low Speed crystal, ceramic resonator or cost-s***ing RC. This device also includes an internal 16MHz RC oscillator for system clock and includes an internal low frequency RC oscillator for slow mode controlled by programming.
