    Product>>8051 MicroController>>STC15W408AS series

Features:

 

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 4K/8K/10K/12K/13K/15.5K FLASH program memory with flexible ISP/IAP capability,

can be repeatedly erased more than 100 thousand times.
on-chip 512 bytes SRAM: 256 byte scratch-pad RAM and 256 bytes of auxiliary RAM

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.
8 channels and 10 bits Analog-to-Digital Converter (ADC), the speed up to 300 thousand times

per second, 3 channels PWM also can be used as 3 channels D/A Converter(DAC).
3 channels Capture/Compare uints (CCP /PCA /PWM)

---- can be used as 3 Times or 3 external Interrupts

(can be generated on rising or falling edge) or 3 channels D/A Converter
The high-speed pulse function of CCP/PCA can be utilized to to realize 3 channels 9 ~ 16 bits PWM

(each channel of which takes less than 0.6% system time)
The clock output function of T0, T1 or T2 can be utilized to realize 8 ~ 16 bit PWM with a high degree

of accuracy (which takes less than 0.4% system time)
nternal 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~+65°C)

in normal temperature and wide frenquency adjustable between 5MHz and 35MHz (5.5296MHz /

11.0592MHz / 22.1184MHz / 33.1776MHz).
No need external crystal and reset, and can output clock and low reset signal from MCU.
Operating frequency range:0- 35MHz, is equivalent to traditional 8051:0~420MHz.
A high-speed asynchronous serial port----UART ( can be regarded as 3 serial
ports by shifting among 3 groups of pins):

--UART(RxD/P3.0, TxD/P3.1) can be switched to (RxD_2/P3.6, TxD_2/P3.7),

also can be switched to (RxD_3/P1.6, TxD_3/P1.7).

A high-speed synchronous serial peripheral interface----SPI.
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
Power management mode: Slow-Down mode, Idle mode(all interrupt can wake up Idle mode),

Stop/Power- Down mode.

Timers which can wake up stop/power-down mode: have internal low-power special wake-up Timer.
Resource which can wake up stop/power-down mode are:

INT0/P3.2, INT1/P3.3 (INT0/INT1, may begenerated on both rising and falling edges),

INT2/P3.6, INT3/P3.7, INT4/P3.0 (INT2 /INT3/INT4, only be generated on falling edge);

pins CCP0/CCP1/CCP2; pins T0/T1/T2(their falling edge can wake up

if T0/T1/T2 have been enabled before power-down mode, but no interrupts can be generatetd);

internal low-power special wake-up Timer.
Five Timers/Counters, two 16-bit reloadable Timer/Counter(T0/T2, T0 is compatible compatible

with Timer0/Timer1 of traditional 8051)

T0/T2 all can independently achieve external programmable clock output,

3 channels CCP/PWM/PCA also can be used as three timers.
Programmable clock output function(output by dividing the frequency of the internal system clock

or the input clock of external pin):

he Programmable clock output of T0 is on P3.5/T0CLKO (output by dividing the frequency of the

internal system clock or the input clock of external pin T0/P3.4)

The Programmable clock output of T2 is on P3.0/T2CLKO (output by dividing the frequency of the

internal system clock or the input clock of external pin T2/P3.1)

Three timers/counters in above all can be output by dividing the frequency from 1 to 65536.

The Programmable clock output of master clock is on P5.4/MCLKO, and its frequency can be divided

SysClk/1, SysClk/2, SysClk/4.

The master clock can either be internal R/C clock or the external input clock or the external crystal

oscillator.

SysClk is the frequency of master clock. SysClkO is the output of master clock.
One 15 bitsWatch-Dog-Timer with 8-bit pre-scaler (one-time-enabled)
advanced instruction set, which is fully compatible with traditional 8051 MCU, have hardware

multiplication / division command.
26/18/14 common I/O ports are available, their mode is quasi_bidirectional/weak pull-up

(traditional 8051 I/O ports mode) after reset, and can be set to four modes: quasi_bidirectional /weak

pull-up, strong pushpull/ strong pull-up, input-only/high-impedance and open drain.

the driving ability of each I/O port can be up to 20mA, but it don't exceed this maximum 90mA that

If I/O ports are not enough, it can be extended by connecting a 74HC595

Besides, cascading several chips also can extend to dozens of I/O ports.
Package: SOP28,TSSOP28,QFN28,SKDIP28,SOP20, DIP20,TSSOP20,SOP16, DIP16.
All products are baked 8 hours in high-temperature 175°C after be packaged ,Manufacture guarantee

good quality.
In Keil C development environment, select the Intel 8052 to compiling and only contain < reg51.h >
