General Overview of STC15W201S series MCU
1. Introduction of STC15W201S series MCU (In abundant supply)
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( 0.3%) with 1% temperature drift (-40ć~+85ć) while 0.6% in normal

temperature (-20ć~+65ć) 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% faster than STC early 1T series
(such as STC12/STC11/STC10 series) at same clock frequency.
