40-channel PWM MCUs

       SC95FWXX series is an industry-grade Flash microcontroller with enhanced 1T 8051 core, and its instruction sets are downward compatible with standard 80C51 series.

       SC95FWXX series is built in up to 40-channel 12-bit PWM, supporting independent mode and complementary mode.

       SC95FWXX is equipped with super-high speed 1T8051 CPU core running with the frequency up to 32MHz. Under the same working frequency, its execution speed has doubled other 1T8051; besides, internally-integrated IC hardware multiplier and divider as well double DPTR data pointer are used for speeding up the data operation and movement speed. Neither hardware multiplier nor divider occupies CPU cycle with its operation executed by hardware and the speed being dozens of times faster than that executed by software; Double DPTR data pointer can be used to accelerate data storage and movement.

       SC95FWXX series features high performance and high reliability with a wide operating voltage range of 2.0V-5.5V and ultra-wide operating temperature range of -40℃-105℃ and has a strong capacity of 6KV ESD and 4KV EFT. It adopts industry-leading eFlash process with Flash writing more than 100,000 times, which can be saved for 100 years at room temperature. 

       SC95FWXX series 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 power-down mode, the typical power consumption in 5V is about 2mA; in normal working mode, the typical value in 5V is about 5.2mA@32M.

       SC95FWXX series also integrates super-rich hardware resources: 64 Kbytes Flash ROM, 4 Kbytes SRAM, 1 Kbytes EEPROM, built-in BootLoader; up to 46 GP I/Os (step control partially), 16 externally interruptible IOs, 5 16-bit timers, 1 analog comparator, 8+32-channel 12bit PWM, internal ±2% high-precision high-frequency 32/16/8/4MHz oscillator and ±4% precision low-frequency 32kHz oscillator, 32.768kHz externally-connected crystal oscillator, etc. Besides, SC95FWXX also internally integrates 17-channel 12-bit high-precision 1M high-speed ADC with 1.024V/2.048V ADC reference voltage function. 1 UART and 3 USCIs (UART/IIC/SPI). So many functions are integrated in SC95FWXX series, reducing the quantity of peripheral components of the system, saving the space of circuit board and system costs.

       SC95FWXX 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.

       SC95FWXX features excellent anti-interference performance, high reliability, large memory, multiple interfaces, low power consumption and high efficiency, which is highly suitable for applications in such fields as LED control, stepper motor control and other multi-channel PWM applications.
