HI,
I have been using CY8C28452 and CY8C27443 till now for any project development in my company but my last project has a large numbers of global variable declaration so its not working well in this ic. so i started programming on CY8C29466 IC. Here i found something surprising Result.
when i was using CY8C28452 last time for latest project that time
Rom size was 96 % full
Ram size was 72% full,183 bytes used (does not include stack usage).
After i moved to CY8C29466. now same configuration and program write for this IC. it is giving me result is below:
Rom size was 47 % full
Ram size was 72% full,183 bytes used (does not include stack usage).
here i found Rom size is decrease but Ram size remain same.
why its happening ????
CY8C29466 has a double Ram size compare to CY8C28452 still why result is same??

Hi
in Project> Project settings , select the option Enable paging.
This enables Large Memory Model and you can work with 2 K RAM (8 pages) of the CY8C29466.

Probably a simple misunderstanding. When the Rom size becomes larger, the percentage of used rom decreases. The number of bytes used (nearly) stays the same.
Same with sram: Your project uses the same amount of sram (183 bytes) regardless of the configuration.

Consider to switch to a PSoC4 device which comes with quite a lot more resources. The prototype kits allow for debugging and have got 4 to 16KB of SRam. Start by downloading Creator 4. and learning how to handle the new IDE.
