Brief introduction

1) Enhanced 8051cpu, 1T, a single clock / machine cycle, the speed is 7-12 times faster than the ordinary 8051, 20%faster than the STC12 series;
2) Wide working voltage:
STC15W408AS series working voltage: 5.5V-2.4V
3) 4K/8K/10K/12K/13K intewes
4) Integrated 512 bytes of SRAM
5) There is an EEPROM function in the film, more than 100,000 times, more than 100,000 times
6) ISP/IAP, in the system programmable/in application programming, no programmer/simulator
7) 8 channels 1o high -speed ADC, speed can be selected 300,000 times/second, 3 -way PWM can also be used as 3 DA
8) A total of 3 channel capture/comparison unit (CCP/PWM/PCA) can also be used to achieve 3 timers or 3 external interruptions (supporting rising edge/decrease edges) or 3 D/A D/A
9) Internal high -reliable reset, level 8 optional reset threshold voltage, can completely save the external reset circuit
10) Internal high-precision R/C clock, ± 1%warm fluttering (-40 ℃- +85 ℃), 5th of thousands of thousands of thousands of thousands of thousands, internal clocks from 5MHz-35MHz (5.5296MHz/11.0592MHz/22.1184MHz/33.1776MHz)

Core board characteristics:
1. The core board uses STC15W408AS-TSSOP20 packaging chip with a small size.

2. The LED light can also be used as a power indicator, just need to put the resistor welding to the GND end!(The default welding LED is connected to P10)

3. Leading 6 VCC and GND, it is greatly convenient for expansion!

4. PCB size: 40.5*15mm;

5. Lead out all IO ports, 2.54 integer multiplex pitch interface, which is convenient for welding on the cave plate!

Provide PDF schematic diagram, test routine ~!Intersection

The core board pre -filled the LED light flickering procedure. After receiving the goods, you can just determine whether the core board works is normal!
