SMT332/372 User Manual 

 

TMS320C6201/6701 (‘C6x01) 

The TMS320C6201 (‘C6201) will run at 200MHz with zero wait-states from internal 
SRAM. The TMS320C6701 (‘C6701) will run at 166MHz with zero wait-states from 
internal SRAM. 

The clock used for the ‘C6x01 is provided from an on-board source only, unlike other 
‘C4x (TMS320C4x) TIMs which can select the CPU speed from an external source 
via the TIM motherboard. The on-board source is a clock synthesiser from 
MicroClock, and its clock output is user selectable (via jumpers) from between 118 
and 200MHz. 

The configuration (config) feature is fully implemented and provides a single open 
collector line which can be held low until the module has been configured. This is 
provided by a control register accessible by the ‘C6x01. 

 

Boot Mode 

The ‘C6x01 is capable of booting in several different modes. On the 
SMT332/372, the boot mode is defined such that the ‘C6x01, after reset, will 
copy the first 64kb of flash data into internal program RAM, and then execute 
that code. 

The second stage (code execution), sets up all necessary ‘C6x01 internal 
registers, and then configures the FPGA (communications port  {comm port} 
controller) from other data held within the flash memory. 

The final stage is to execute a ‘C4x type boot loader. This process continually 
examines the state of the comm port status register and will, when it 
determines which port data is present, then load a ‘C6x01 boot file which is 
then executed. Refer to the 

Application Development

 section for more 

information. 

Whilst this stage of booting is in progress, all of the other comm ports will be 
ignored
