Hello to all,
From now i was devloping application using LPC 2138, it has 32K RAM and 512K Flash. My programe is requiring more SRAM, as I am using 100k Image sensor, it quite more image processing is there.
#1) can I get any flashless mc from LPC track itslef [so i could have minimmum changes in code if changing mc], but with more then 100k of SRAM ??
I have checked paramatric search of keil, i was unable to locate uc more then 64k in Philis LPC track.
#2) Is it possible to interface external SRAM with current LPC 2138 ???
#3) If I plan to go with ATMEL's controller AT91R40008 [or other uc with <100K SRAM and with very less or no flash. HOW MUCH MY CODE OF CURRENT APPLICATION SUPPOSE TO AFFECT??
In my code i have devloped GPIO modules, Camera IC's Drivers, serial interface modules and IAP modules.
Please guide me, it is critical for me
Regards, mittal
If you need more SRAM, pick a microcontroller with external memory interface and attach SRAM to it. I belive MCUs from the LPC2200 series come with external memory interface.

thanks for kind advice,
Actually its true that i need to continue to LPC track rather then ATMEL, to avoide overall program architecture and [cost too, as ATMEL is not having general onchip pheripherals also]
As you told also,I am in favor of lpc2214, and then i need to interface external RAm to it. If i use RAM as external to controller, How should my programe can use external address space? Can you suggest from where can i have these informations..
Thanks in advance mittal
