This is ok if you do not have a bootloader to include in your device.

Thanks for your replay. when i check my application size in .map file it show's

Total RO Size (Code + RO Data) 64700 ( 63.18kB)
Total RW Size (RW Data + ZI Data) 41776 ( 40.80kB)
Total ROM Size (Code + RO Data + RW Data) 65152 ( 63.63kB)

If you are using S112 will take 100KB so you have 92KB for rest of your application. If you use FDS then you need two more pages for SWAP and garbage collection so you are only left with (192 - 100 - 2*4) which is 84KB. If you can fit you application there, then you have no problem.

Only problem is that if you need to fit the bootloader, then there is very limited amount of space. In that case you need to spare (1 page) 4KB for MBR settings and 4KB for bootloader settings, so your application+ bootloader will only be left with (84 -2*4) = 76KB.

You can either fit a simple application there or a connectivity firmware so that you can use your chip purely as connectivity chip.
