The e2v PowerPC and HiTCE Packages

Atmel PC7410MGH450LE – Motorola Marked Package – 2003

In the 1970’s second sources were quite important in the processor industry.  They provided a stable supply of a designed in part if the primary manufacturer (which often only had a fab or 2) had problems.  They also could widen the market for the processor.  Many of these agreements were kept active for decades after, resulting in some interesting results.

Motorola licensed many of their design to SGS, which later merged with Thomson to become STMicroelectronics. though the Thomson name was still used.  Thomson license built most of Motorola’s product line, as well as many high reliability versions.  In 1999 Atmel bought Thomson-CSF Semiconductors, and continued to make Motorola products (in their Grenoble France fab), which now included Motorola’s PowerPC line as well as the 68k line of processors.  This portion of Atmel was sold to e2v (in England) in 2006, which continued to produce the Motorola (now spun off as Freescale) PowerPC line, now branded as e2V.

The packaging used by e2v (and previously Atmel) is the same as that used by Motorola/Freescale.  The packages were custom made for Motorola/Freescale by Kyocera (and others) and so often chips with both Atmel/Motorola and e2v/Freescale markings can be found.  It is this packaging that is of interest, as it shows an interesting aspect of processor design.
