 		 #155763 - ATMega128 but new to 8052 (help)
Hi all,
It is my first time here. Someone recommended me this we page and to acquire a 8052 and a experiment board.

Well, I am in a project where two 8 bit microcontrollers must speack to each other via Laipac radio.

(http://www.laipac.com/easy_trf24_eng.htm )

The first micro I purchaise was a ATMega128 in an STK300 evaluation board.
The software of this micro is finished. Now it is time to purchaise the other one. Can I put you some questions before purchaising?

ATmega128 has a flat memory space with 128K program memory (FLASH), 4K RAM (SRAM) and 4 K EEPROM. It supports till 64 K of SRAM.

1. Does memory space of the 8052 is flat or we have to take care of segments?

STK300 comes with the avrstudio wich includes a code simulator and a free compiler (avr gcc)

2. IS there any simulator for the 8052 to test source code before downloading it?
Can I program 8052 using C? IS there any form of debug step by step on the simulator if any?

3. Which is whe evaluation board you recommend for me? (under 100 euros/dollars)?

Please, if 8052 doesnt feet my needs can you recommend me another type of 8 bit microcontroller?

Many thanks

Alex
