STC15W408AS core board system board learning board 51 microcontroller development board TTSOP20

Graphic details

Introduction to STC15W408AS series MCU:

1) Enhanced 8051 CPU, 1T, single clock/machine cycle, 7-12 times faster than ordinary 8051, 20% faster than STC12 series;

2) Wide operating voltage:

STC15W408AS series operating voltage: 5.5V-2.4V

3) 4K/8K/10K/12K/13K Byte on-chip Flash program memory, erase and write times more than 100,000 times
4) On-chip integrated 512 bytes of SRAM
5) On-chip EEPROM function, erase and write times more than 100,000 times
6) ISP/IAP, in-system programmable/in-application programmable, no programmer/emulator required
7) 8-channel 10-bit high-speed ADC, optional speed 300,000 times/second, 3-way PWM can also be used as 3-way DA
8) A total of 3-channel capture/compare units (CCP/PWM/PCA), can also be used to implement 3 timers or 3 external interrupts (support rising edge/falling edge interrupts) or 3-way D/A
9) Internal high-reliability reset, 8-level optional reset threshold voltage, can completely save the external reset circuit
10) Internal high-precision R/C clock, ±1% temperature drift (-40℃- +85℃), normal temperature, temperature drift 0.5%, internal clock from 5MHz-35MHz optional (5.5296MHz/11.0592MHz/22.1184MHz/33.1776MHz)
