TMS570LC4357: MEMORY

user5093781

Hi. I am thinking of operating with the following configuration. GCLK:300MHz, HCLK:150MHz, RWIT:3 Q1:If the cache is used, can the flash memory and SRAM access speed be considered 300 MHz? Q2:If the cache is not used, can the flash memory and SRAM access speed be considered as 150MHz? Best Regards.

Hello,

If cache is enabled, the cache is clocked by GCLK (no waitstates).

For SRAM, it is clocked by HCLK and is limited to maximum 150 MHz, and data waitstates = 0.

For Flash, L2 flash is clocked by HCLK and is limited to maximum 150 MHz, and waitstates = 0~3. The flash can support zero data wait state up to 45 MHz.
