The SN8P2602B is a RISC-like high performance and low power consumption 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 48-bytes RAM, Two 8-bit timer (T0, TC0), a watchdog timer, three interrupt sources (T0, TC0, INT0), and 4-level stack buffers. Besides, user can choose desired oscillator configuration for the controller. There are four external oscillator configurations to select for generating system clock, including High/Low speed crystal, ceramic resonator or cost-saving RC. This device also includes an internal RC oscillator for slow mode controlled by programming.
