SC92L series general purpose MCU is a series of industry-grade Flash microcontroller with wide-voltage and low-power 8051 core, and its instruction sets are fully compatible with traditional 8051 series.

SC92L series general purpose MCU is internally integrated with hardware multiplier and divider and hardware CRC to speed up the data operation. Neither hardware multiplier and divider nor hardware CRC occupies CPU cycle with its operation executed by software and the speed faster than that implemented by software.

SC92L series general purpose MCU features high performance and high reliability with a wide operating voltage range of 1.8V-5.5V and ultra-wide operating temperature range of -40℃-105℃ and has a strong capacity of 8KV ESD and 4KV EFT. Flash can be written for more than 100,000 times, which can be saved for 100 years at room temperature.

SC92L series general purpose MCU is a built in low-power watchdog timer (WDT) with 4 levels of optional low voltage reset (LVR) function and system clock monitoring function, featuring low power consumption capability in operation and power-down mode. In normal working mode, the typical value in 5V is about 4.5mA@32M.

SC92L series general purpose MCU also integrates super-rich hardware resources: 16-64 Kbytes Flash ROM, up to 4 Kbytes SRAM, 0-4 Kbytes LDROM, 1 Kbytes EEPROM and supported BootLoader; up to 46 GP I/Os, multiple externally interruptible IOs, 5 16-bit timers, up to 17-channel 12-bit high-precision ADC, built-in 2.4/1.024/2.048V ADC reference voltage, multi-channel complementary PWM with deal-time insertion, multiplier and divider, CRC check module, built-in LCD/LED driver; internal high-precision high-frequency 32MHz oscillator, /1 /2 /4 /8 frequency division of high frequency clock for system clock, internal ±4% precision low-frequency 32kHz oscillator, externally connected 32.768kHz crystal oscillator and 8 levels of LPD, UART, SPI, TWI and other communication interfaces.

SC92L series general purpose MCU is convenient for developing and debugging, featuring In-System Programing (ISP), In-Circuit Programing (ICP) and In-Application Programing (IAP). It is allowed to debug and upgrade the program memory directly on the circuit board even when the chip is working or powered on.

      SC92L series general purpose MCU is characterized with excellent anti-interference performance, which is highly suitable for applications in IoT controls, smoke sensor, intelligent household appliances, RF modules, smart wearable products, Sensor/MEMS modules, temperature/humidity recorders and battery power supply, etc.
