SN8F5959 is an 8-bit architecture microcontroller which compatible with MCS-51 instruction set. It runs at up to 12.1 times faster than the original 8051 at the same frequency. Meanwhile, its advanced semiconductor technology provides a wide range operation voltage, from 1.8 V to 5.5 V, and working temperature between -40°C and 105°C at 32 MHz CPU clock rate.

The microcontroller builds in a 128 KB flash memory (IROM), 256 bytes internal RAM (IRAM) and 8 KB on-chip external RAM (XRAM). A Hardware MDU dramatically improves mathematical operations performance. Furthermore, a 9 input channels 24-bit resolution Delta-Sigma ADC, 12-bit DAC, dual rail to rail OPA ,4*36 or 6*34 LCD driver (144~204 dots), One Programmable Gain Instrument Amplifier :x1~128 , Three 16-Bit Timer/Counter with Auto reload, PWM Output function, One 8-Bit base Timer for RTC , Communication interfaces (UART*2, SPI*1, I2C*1) to fit in the vast majority of consumer electronics,、Glucose HCT meter、Thermometer、Weight scale and Medical Measurement Applications.
