SN8F5937 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 85°C at 32 MHz CPU clock rate.

The microcontroller builds in a 128 KB flash memory (IROM), 256 bytes internal RAM (IRAM) and 6 KB on-chip external RAM (XRAM). A Hardware MDU dramatically improves mathematical operations performance. Furthermore, a 11 input channels 24-bit resolution ΔΣ ADC and 12-bit resolution SAR ADC, 12-bit resolution DAC, One Programmable Gain Instrument Amplifier, 4*44 or 6*42 LCD driver (176~252 dots), Two OP-Amps and comparator, one Charge Pump Regulator (AVDDR and ACM), 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 Meter 、Blood Pressure、Thermometer Application and Medical Measurement Applications.
