Texas Instruments MSP50C614 manual Device Production Sequence, Nprf

Device Production Sequence

All prototype devices are shipped with the following disclaimer: It is understood that, for expediency purposes, the initial 25 prototype devices (and any additional prototype devices purchased) were assembled on a prototype (i.e., not production-qualified) manufacturing line, whose reliability has not been characterized. Therefore, the anticipated inherent reliability of these devices cannot be expressly defined.

The customer verifies the operation and quality of the prototypes and responds with either written customer prototype approval or disapproval. A nonrecurring mask charge that includes the 25 prototype devices is incurred by the customer. A minimum purchase is required during the first year of production.

Customer Sends Code (in QBN or TITAG format) and completes Section 1 of the

NPRF

TI completes Section 2A of NPRF and sends verifi- cation code (in QBN for- mat) with BIST included & NPRF form to customer

Customer verifies

code is correct.

Customer signs Section 3 of the NPRF and sends it to TI

TI generates prototype parts for Customer verification

TI sends sample devices

to customer for

verification

Customer verifies the

devices work properly and completes Section 4 of the NPRF.

TI produces the chip

in production quantities

Texas Instruments recommends that prototype devices not be used in produc- tion systems. The expected end-use failure rate of these devices is undefined; however, it is predicted to be greater than that of the standard qualified produc- tion.
