TMS570LS3137: Security/feature summary

Part Number: TMS570LS3137

I am attempting to put together a competitive feature summary for a customer inquiry.  I have answered what I can, but want to have expert validate that I have not missed anything obvious.

Customer question   :   Answer

Physical Isolation of Power domains :   Yes, but need clarification on meaning of physical isolation.  All domains have transistor/gates that traverse power domain boundaries.

Temperature monitoring: No

Reset Monitoring: External power monitor required. (Reset source captured in registers)  Internal voltage monitor can initiate reset.

CWD--> nRST pin available is bi-directional. can be asserted externally to initiate a warm/soft reset or monitored to monitor reset status.

Redundant Boot/Safety/Error reporting mechanism: BIST (CPU,RAM), Error Signal Pin, voltage & Clock monitoring, PLL slip detection, watchdog [external recommended], ECC ( FLASH, RAM),  Lockstep CPUs, very high diagnostic coverage across the device, Parity on Peripheral RAMs,... reference Safety Manual : www.ti.com/.../spnu511

CWD--> safety: IEC61508 SIL3 and ISO26262 ASILD certified, rich set of functional safety tools/software offerings (CSPs, CQK, Halcogen, SafeTI Diagnostic Lib),

Security measure to prevent reverse engineering (please list all): 128bit JTAG security. User & Privilege mode.

I have same set of questions for the LC4357 that I will post separately.

Thanks,

Wade
