SN8F5918 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 2.0 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 32 KB flash memory (IROM), 256 bytes internal RAM (IRAM) and 512 bytes on-chip external RAM (XRAM). Hardware MDU dramatically improves mathematical operations performance. Furthermore, a 10 input channels/24-bit resolution ADC, One Programmable Gain Instrument Amplifier, 4*36 or 6*34 LCD driver (144~204 dots), One BIA( Bioelectrical Impedance Analysis) circuits , one Charge Pump Regulator (AVDDR and ACM), Two16-Bit Timer/Counter with Auto reload, PWM Output function, One 8-Bit base Timer for RTC , Communication interfaces (UART,I2C) to fit in the vast majority of consumer electronics, Body fat monitor、Thermometer Application and Medical Measurement Applications.
