The SMC-27X2 has a small, dedicated memory area called Turbo Ram. There are 64 bytes, which reside 
between address locatio n 128 and 192. Instructions written here during program mode use “real” internal 
RAM rather than EEPROM in order to achieve these advantages: 

1. Very fast execution.  EEPROM access time is 1 Ms. or more per byte. 
2. No wear and tear on the EEPROM. 
3. The trip service routine executes at address 160. 

 
Macros may be downloaded directly into this area and executed as frequently as desired. Programs in this 
area are stored in corresponding NV memory and “down-loaded” at power up, making an effective shadow 
RAM.
