Product Descriptions

The SC92F7423/7422/7421/7420 (hereinafter referred to as the SC92F742X) is a kind of enhanced high-speed 1T 8051-based industrial Flash Microcontroller unit (MCU), in which the instruction system is completely compatible with standard 8051 product series.

The SC92F742X is integrated with 16K bytes Flash ROM, 256 bytes+256 bytes SRAM, 128 bytes EEPROM, up to 26 General-purpose I/Os (GPIO), 14 IO external interrupters, three 16-bit timers, 11- channel 12-bit high-precision ADC, 6-channel independent 8-bit PWM, IO ports driven hierarchical control (P0 and P2 ports) with 4-level drive capability, internal ±1 PERCENT high-precision 16/8/4/1.33MHz highfrequency oscillator and 4 PERCENT precision low-frequency 128 kHz oscillator, external crystal oscillator interface, two SSI communication interface and other resources. To improve the reliability and simplify the circuit design, the SC92F742X is also built in with 4-level optional LVR voltage, 2.4V ADC reference voltage and other high-reliability circuits.

The SC92F742X 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.
