We just received a PRODUCT CHANGE NOTIFICATION SUMMARY from our supplier.
It states “FW 02.24.05.06 will reduce the risk of damaging and corrupting EM7455 and MC7455 modules when
the recommended power off timing requirement is not followed.”
Does this problem have to do with disabling module by bringing W_DISABLE_N low and keeping USB_D+ high for more than 25s? Or there is some other power off timing requirement that it deals with?
