More document click to download: STC15W408AS Introduction to MCU: 1) Enhanced 8051CPU, 1T, single clock / machine cycle, speed 7-12 times faster than ordinary 8051, 20% faster than STC12 series; 2) Wide working voltage: STC15W408AS series working voltage: 5.5V-2.4V 3) 4K/8K/10K/12K/13K bytes of on-chip Flash program memory, more than 100,000 erase and write times 4) On-chip integrated 512-byte SRAM 5) There is an on-chip EEPROM function, and the number of times of erasing is more than 100,000 times. 6) ISP/IAP, programmable in system / programmable in application, no programmer/emulator required 7) 8-channel 1O-bit high-speed ADC with 300,000 times/second speed, 3-way PWM can also be used as 3-way DA 8) A total of 3 channels of capture/compare units (CCP/PWM/PCA) can also be used to implement 3 timers or 3 external interrupts (supporting rising/falling edge interrupts) or 3 channels of D/A 9) Internal high-reliability reset, 8-level optional reset threshold voltage, can completely eliminate the external reset circuit 10) Internal high-precision R/C clock, 1% temperature drift (-40C- +85C) normal temperature, temperature drift of 5 thousand, internal clock from 5MHz-35MHz optional (5.5296MHz/11.0592MHz/22.1184 MHz/33.1776MHz) Features: 1. This core board is made of STC15W408AS-TSSOP20 package chip, which is small in size. 2. The led light can also be used as a power indicator. Just solder the resistor to the GND terminal. (The default soldering LED is connected to P10) 3. Lead 6 channels of VCC, GND, which is very convenient for expansion. 4. PCB size: 40.5*15mm; 5. Lead all IO ports, 2.54 integer spacing pin connector, easy to solder on the hole plate. Package Included: 1 x STC15W408AS Core Board Minimum System Board
