Content for STC15W4K32S4

STC15W4K32S4 series MCU is a single-chip microcontroller based on a high performance 1T architecture 8051 CPU, which is produced by STC MCU Limited. It is a new generation of 8051 MCU with high speed, high stability, wide voltage range, low power consumption and super strong anti-disturbance. With the enhanced kernel, STC15W4K32S4 series MCU is faster than the traditional 8051 one in executing instructions (about 8~12 times the rate of the traditional 8051 MCU), and has a fully compatible instruction set with traditional 8051 series microcontroller. External expensive crystal can be removed by being integrated internal high-precise R/C clock(f0.3%) with f1% temperature drift (-40 ~+85 ) while f0.6% in normal temperature (-20 ~+65 ). External reset curcuit also can be removed by being integrated internal highly reliable one with 16 levels optional threshold voltage of reset. The STC15W4K32S4 series MCU retains all features of the traditional 8051 one. In addition, it has 8-channels and 10-bits PWM, 8-channels and 10-bits A/D Converter(300 thousand times per sec.), Comparator, large capacity of 4K bytes SRAM, four high-speed asynchronous serial ports----UARTs(UART1/UART2/UART3/UART4) and a high-speed synchronous serial peripheral interface----SPI.
