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.

•

Enhanced 8051 Central Processing Unit, 1T, single clock per machine cycle, faster 8~12 times than the rate of

a traditional 8051.

•

Operating voltage range: 5.5V ~ 2.4V.

On-chip 1K/2K/3K/4K/5K/7.5K FLASH program memory with flexible ISP/IAP capability, can be repeatedly

erased more than 100 thousand times.

•

on-chip 256 bytes SRAM

On-chip EEPROM with large capacity can be repeatedly erased more than 100 thousand times.

ISP/IAP, In-System-Programming and In-Application-Programming , no need for programmer and emulator.

Internal hghly reliable Reset with 16 levels optional threshold voltage of reset, external reset curcuit can be

completely removed

•

Internal high- precise R/C clock( 0.3%) with 1% temperature drift (-40 ~+85 ) while 0.6% (-20

f f ć ć f ć

~+65 ) in normal temperature and wide frenquency adjustable between 5MHz and 35MHz (5.5296MHz /

11.0592MHz / 22.1184MHz / 33.1776MHz).

•

Operating frequency range: 0- 35MHz, is equivalent to traditional 8051:0~420MHz.

No need external crystal and reset, and can output clock and low reset signal from MCU.

A high-speed asynchronous serial ports----UART ( can be regarded as 2 serial ports by shifting among 2

groups of pins): UART1(RxD/P3.0, TxD/P3.1) can be switched to (RxD_2/P3.6, TxD_2/P3.7).

•

Support the function of Encryption Download (to protect your code from being intercepted).

Support the function of RS485 Control

Code protection for flash memory access, excellent noise immunity, very low power consumption
