TMS320F2808: TMS320F2808 maximum erase time

Rogers Chen

Part Number: TMS320F2808

Dear TI CSC，

I noticed that the maximum erase time written on the TMS320F2808 datasheet is 15 seconds, this parameter is for the first 100 erase/program cycles. But if we erase the IC for more than 100 cycles, what is the maximum erase time? Is it still 15s? Thank you~

Rogers,

I would reference this previous E2E post https://e2e.ti.com/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/808561/tms320f28035-how-much-is-the-flash-erase-time-if-the-erase-cycle-100/2992830?tisearch=e2e-sitesearch&keymatch=F05%25252520Flash#2992830

To summarize, the device has the potential for the erase time to be >15s after 100 erase/program cycles, but it won't necessarily be the case. If we are looking to approach the 20k W/E cycles that are guaranteed by the DS, I think it would be safe to double the timeout to 30s for the life of the device. Most devices will not take the full 15s, but there is a distribution that may see this.

Best,

Matthew
