SN8F58243 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 16 MHz CPU clock rate.

The microcontroller builds in a 32 KB flash memory (IROM), 256 bytes internal RAM (IRAM) and 1536 bytes on-chip external RAM (XRAM). A hardware MDU dramatically improves mathematical operations performance. Furthermore, a 16 input channels/12-bit resolution ADC, 4*36/6*34/7*33/8*32 LCD driver (144/204/231/256 dots), 24 touch channels, four PWM generator, interfaces (3 UARTs, I2C) and 16-bit timers were designed to fit in the vast majority of consumer electronics, home automation and motor control applications.
