一：简介

ATMEL AT89SXX ISP编程器V1.3是一款基于RS232串行通信的编程器，同时网友也可以通过USB-UART转换IC，制作成USB接口的ISP编程器的哦。非常简单易制的一款ISP编程器。（网友可以自由发挥做成USB接口的哦）

二：硬件电路

ATMEL AT89SXX ISP编程器V1.3的硬件电路非常简单有一颗RS232通信IC和AT89C2051构成。见下面的方框图。

下图是一个完整的ATMEL AT89SXX ISP编程器V1.3的原理图：

三：固件

Assemble the circuit and burn the firmware into an AT89C2051(you will need a conventional parallel Programmer to Program the AT89C2051).

四：软件

The Software is a Windows GUI application and supports all programming functions. When you run the software for the first time it looks for a valid programmer on COM1. If the Programmer is connected to say COM2 you will receive an error message but when the application starts select Options->Settings on the Menu and specify the correct COM Port.

Following are the main features of this software,

Device Supported - AT89S51, AT89S52, AT89S8252, AT89S8253.

Read and write  Intel Hex files.

Chip Erase.

Verify.

Lock.

Read Device Signature.

Advanced Device Specific Functions.
