Product Descriptions

STC15W201S  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 of  high speed, high stability, wide voltage range, low power consumption and super strong anti-disturbance. Besides, STC15W201S series  MCU  is  a  MCU  of  super  advanced  encryption,  because  it  adopts  the  ninth  generation  of  STC  encryption  technology.  With  the  enhanced  kernel,  STC15W201S  series  MCU  is  faster  than  a  traditional  8051  in  executing  instructions  (about  8~12  times  the  rate  of  a  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(f0.3PERCENT)  with  f1 PERCENT  temperature  drift  (-40 ℃~+85 ℃)  while  f0.6PERCENT  in  normal  temperature  (-20 ℃~+65 ℃)  and  wide  frenquency  adjustable  between  5MHz  and  35MHz.  External  reset  curcuit  also can be removed by being integrated internal highly reliable one with 16 levels optional threshold voltage of reset. The STC15W201S series MCU includes a high-speed asynchronous serial port----UART( can be regarded as 2 serial ports by shifting among 2 groups of pins), comparator and so on. STC15W201S series MCU is usually used in

serial communication or electrical control or some occasion with strong disturbance.

In Keil C development environment, select the Intel 8052 to compiling and only contain < reg51.h > as head-er file.

STC15 series MCU with super high-speed CPU core of STC-Y5 works 20 PERCENT faster than STC early 1T series (such as STC12/STC11/STC10 series) at same clock frequency.
