Product Introduction

The SC92F8547/8546/8543/8541 (hereinafter referred to as the SC92F854X) is a kind of enhanced super high-speed 1T 8051-based industrial Flash Microcontroller unit (MCU), in which the instruction system is completely compatible with standard 8051 product series.

The SC92F854X contains 32K bytes Flash ROM, 2K bytes SRAM, 128 bytes EEPROM. The SC92F854X has built-in 31-channel high-sensitivity Touch Key circuit, up to 46 General-purpose I/Os (GPIO), 16 IO external interrupters, three 16-bit timers, 17-channel 12-bit high-precision ADC, 1 analog comparator, 8- channel independent 12-bit PWM, IO ports driven hierarchical control, 1 16*16-bit hardware Multiplier Divide Unit (MDU). The system clock source is internal ±1 PERCENT high-precision 16/8/4/1.33MHz high frequency oscillator. The low-frequency clock source is selectable between the ±4 PERCENT precision 128 kHz oscillator and external 32.768 kHz crystal oscillator, two SSI communication interface and other resources. To improve the reliability and simplify the circuit design, the SC92F854X also built in with 4- level optional LVR voltage, 2.4V ADC reference voltage, low-power WDT and other high-reliability circuits.

The SC92F854X features excellent anti-interference performance, which make it possible to be widely applied to industrial control system, such as Internet of Things, intelligent home appliances, home automation, wireless communication, gaming peripherals and consumer applications.
