Chapter 1. Introduction

STC12C5620AD is a single-chip microcontroller based on a high performance 1T architecture 8051 CPU, which

is produced by STC MCU Limited. With the enhanced kernel, STC12C5620AD executes instructions in 1~6

clock cycles (about 8~12 times the rate of a standard 8051 device), and has a fully compatible instruction set with

industrial-standard 8051 series microcontroller. In-System-Programming (ISP) and In-Application-Programming

(IAP) support the users to upgrade the program and data in system. ISP allows the user to download new code

without removing the microcontroller from the actual end product; IAP means that the device can write non-

valatile data in Flash memory while the application program is running. The STC12C5620AD retains all features

of the standard 80C51. In addition, the STC12C5620AD has a 9-sources, 4-priority-level interrupt structure,

10-bit ADC(100 thousands times per second), on-chip crystal oscillator, MAX810 special reset circuit, 4-channel

PCA and PWM, SPI, a one-time enabled Watchdog Timer and so on.
