Part Number: F28E120SC

In F28E12x Real-Time Microcontrollers datasheet (Rev. B) , the feature section mentions that the RAM capacity is 16 KB. Subsequently, the Function Block Diagram on page 4 says it is 12KB. What is the actual capacity of RAM?

    Hi Ganesh,

    The actual RAM capacity is 16KB, which is split into GS0RAM (12kb) and M0/M1 RAM (4KB). The difference is in the way data is shared. 

    • GS - Means Globally shared (any CPU subsystem can use it). 
    • M0/M1 RAM are CPU local RAM.

    You can find further details in the device TRM. The combined RAM that application can use is 16KB.

    Regards,
