SC92L series touchkey 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 touchkey 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 hardware and the speed faster than that executed by software.

SC92L series touchkey 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 touchkey 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 touchkey MCU internally integrates with up to 31 touchkeys, possesses the industry-leading touchkey circuit architecture, featuring high signal to noise ratio, high sensitivity, low power consumption and strong anti-interference, etc., all of which have passed 10V dynamic CS and been applied to touchkey applications in spring buttons, touchless buttons, proximity sensing, water level detection, etc.; meanwhile, SinOne has also offered intelligent integrated development tools, which can adapt themselves to the circuit parameters, have flexible and settable sensitivity and debug an application in 5 minutes. SC92L series touchkey MCU supports running touchkey circuit in low power mode, and can realize 8uA @12KEY 3.3 together with the software library provided by SinOne.

SC92L series touchkey 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 touchkey 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 touchkey 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.
