TMS320F28379S: C2000 microcontrollers forum

In general lead-times for larger direct/distributor orders are ~16 weeks

Yes, the F2837x series was the first introduced in our Gen3 family of 65nm devices about 8 years ago, but it is still in the early / ramp stage of adoption and life cycle.

C2000 devices are used in industrial and automotive applications where customers have very long lifetime demands.  We are still shipping Gen2 devices from late 1990s.

There is TI.com inventory of this F28379S  

2 of the 6 part number variants have immediate stock, and 2 more have stock expected later this month.
