SQTP Specification for PIC16/17
DS30154F-page 2
1996 Microchip Technology Inc.
2.0 PROGRAMMING SEQUENCE
The factory will program the “basic code” first, then pro-
gram the serial number and finally program the code-
protection fuse. Program memory will be verified at
each stage except after code protection. Optionally, the
factory may choose to program the “basic code” and
the “serial number” at the same time. The customer
may specify an ID number (four hex digits) to be pro-
grammed in the ID locations or elect to leave them
unprogrammed.
3.0 SAMPLES
Three (3) verification samples will be provided. These
will be programmed with factory selected random or
sequential codes in the serialization locations. The
three parts will be programmed with three different
serial codes. If order entry has been completed, then
the samples will reflect the first three codes. If code
protection is requested, then one of the three samples
will be code protected.
4.0 THE FOLLOWING LIMITATIONS
APPLY TO THE SQTP
PROGRAM
1. During shipment of serialized parts, no particu-
lar sequence can be guaranteed.
2. In sequential or pseudo-random numbering
scheme, there may be missing serial numbers
(e.g. due to QC sampling).
3. A list of serial numbers programmed can not be
provided, nor will such a list be generated or
maintained by Microchip.
4. For sequential and pseudo-random numbering
schemes, Microchip will maintain last number
used in last shipment and use the next number
as the starting number for the next shipment.
The customer should be prepared to provide a
“new starting number” in the event the flow is
disrupted due to unforeseen events.
