 		 #167167 - AT89S52 easy ISP and P89V51RD2 easy UART ISP
Responding to: ???'s previous message
The AT89S52 is one of the most easiest microcontrollers to work with.
The simple interface to ISP (In System Programming) allows to do any
experiment with software and download the .hex file to the microcontrollers'
flash just in seconds. The AT89ISP programmer from ATMEL is very easy to operate.
The AT89S8253 has more flash (12K) and EEPROM.

Take care of the optional RESET line during programming. For testing and
experimental a simple switch is needed, for production better consider
a supervisor RESET chip.


Another part of former Philips now NXP with UART option for ISP is P89V51RD2.
It has more options like more Flash(64K), CCU, x2, UART ISP.

This part is programmed with Flashmagic Tool using the serial port. You just
have to provide a serial connection with MAX232 or a FTDI chip and the programming
interface is easy too. The programming tool is the Flasmagic

Cant find AT89S53            01/01/70 00:00      
   There's no AT89S53            01/01/70 00:00      
      Datasheet of AT89S53            01/01/70 00:00      
         AT89S8253 should be available            01/01/70 00:00      
            Many Thanks            01/01/70 00:00      
               I use it and am very happy with it!            01/01/70 00:00      
      AT89S53            01/01/70 00:00      
   Why ?            01/01/70 00:00      
      Because it have studied it            01/01/70 00:00      
         AT89S8253 is on the market            01/01/70 00:00      
         8051 !=Atmel            01/01/70 00:00      
            "Atmel" is not synonymous with "8051"            01/01/70 00:00

            NOOOOOOOOOOOO            01/01/70 00:00      
               YES, DO NOT USE THE RC-RESET!!!            01/01/70 00:00      
               Although what you say is probably true ...            01/01/70 00:00
