Product Descriptions

The SC92F8463B/8462B/8461B (hereinafter referred to as the SC92F846XB) is a kind of enhanced high-speed 1T 8051-based industrial Flash Microcontroller unit (MCU) with integrated TouchKey function, in which the instruction system is completely compatible with standard 8051 product series.

The SC92F846XB has a 23-channel dual-mode capacitor TouchKey circuit with low power consumption. The TouchKey circuit can be operated under STOP Mode.

The SC92F846XB is integrated with 16K bytes Flash ROM, 1K bytes SRAM, 128 bytes EEPROM, up to 26 General-purpose I/Os (GPIO), 13 IO external interrupters, three 16-bit timers, 11-channel 12-bit high-precision ADC, 6-channel independent 10-bit PWM, internal ±1 PERCENT high-precision 12/6/2MHz highfrequency oscillator and 4 PERCENT precision low-frequency 128K oscillator、 external crystal oscillator interface, one separate UART, one three-in-one serial communication interface which can be used as UART/SPI/TWI (SSI). To improve the reliability and simplify the circuit design, the SC92F846XB is also built in with 4-level optional LVR voltage, 2.4V ADC reference voltage and other high-reliability circuits.

The SC92F846XB features excellent antiinterference performance, which make it possible to be widely applied to industrial control system, such as intelligent home appliances, home automation, Internet of Things, wireless communication, gaming peripherals and consumer applications.
