A T89C52 Single-chip microprocessor introduction

Selection of Single-chip microprocessor

1. Development of Single-chip microprocessor

The main component part of Single-chip microprocessor as a result of by such centralize to be living to obtain on the chip，In immediate future middle processor CPU。Storage RAM immediately﹑memoy read ROM﹑Interrupt system、Timer /'s counter along with I/O's rim electric circuit awaits the main microcomputer section，The lumping is living on the chip。Although the Single-chip microprocessor r is only a chip，Yet through makes up and the meritorous service be able to on sees，It had haveed the calculating machine system property，calling it for this reason act as Single-chip microprocessor r minisize calculating machine SCMS and abbreviate the Single-chip microprocessor。

1976Year the Inter corporation put out 8 MCS－48Set Single-chip microprocessor computer，After being living more than 20 years time in development that obtain continuously and wide-ranging application。1980Year that corporation put out high performance MCS －51Set Single-chip microprocessor。This type of Single-chip microprocessor meritorous service capacity、The addressing range wholly than early phase lift somewhat，Use also comparatively far more at the moment。1982Year that corporation put out the taller 16 Single-chip microprocessor MCS of performance once

more －96Set。The Single-chip microprocessor computer development havees the performance more and more to be improved﹑More and more distinguishings feature of strain。

2. Adopt the Single-chip microprocessor strong point

Hacker use，Agileization of application。

●Have memory、Calculation and look-up meritorous service capacity。May make the apparatus bearing that the rule can not make。

●The command system is fit for the real-time control。

●Bulk is little，Execution speed is quickly。

●Dependability is high，The antijamming capability is powerful。

●The temperature use limit is vast。

●Power-off protection is improved。

●The product development cycle brief。

●Identical set is much as the necessary interface chip sort，The meritorous service be able to be completely，Be convenient for to pick up achieve the minimal system。

●On the basis of the tall science and technology demand，Integration in common use software，Hardware （In case PL/M language，DAM's wave pattern producer，Analog switch awaits ）Application is agile。

Hence，Native is designed adoping with the Single-chip microprocessor core components designs。

3 . AT89C52 Component

A T89C52 microprocessor main function parameter：

And completely compatible with the MCS-51 product instruction and thepin

The 8K byte is programmable/scratches writes Flash to dodge the fastmemory

1,000 time scratches writes the cycle

Entire static operation: 0Hz - 24MHz

Three levels of encryptions program memory
