SN8F27E60 series 8-bit micro-controller is a new series production applied advanced semiconductor technology to implement flash ROM architecture. SN8F27E65 is RISC-like high performance and wide operating range (1.8V~5.5V @16mips). One clock per instruction cycle (1T) architecture will provide up to 16MIPS computation power. The device is designed with the excellent IC structure including the program memory up to 6K-word Flash ROM, data memory of 512-bytes RAM, 8-level stack buffers, multi-interrupt vector, four 8-bit timers, one 16-bit timer, high performance 12-ch 10-bit ADC, 3-set individual programmable PWMs, 3-type serial interfaces and flexible operating modes. There are three oscillator configurations to select for generating system clock, including High Speed crystal, ceramic resonator or cost-saving RC. This device also includes an internal 16MHz RC oscillator for system clock. Under flash ROM platform, SN8F27E65 builds in in-system-programming (ISP) function extending to EEPROM emulation and Embedded ICE function. Powerful functionality, high reliability and low power consumption can apply to AC power application and battery level application easily.
