Die photograph of a Ferranti Uncommitted Logic Array (ULA)

Summary edit

Description
English: This is a die photograph of a Ferranti Uncommitted Logic Array (ULA), but produced after Ferranti's chip business had been sold on to Plessey Semiconductors.

This array has 4 panels, each with an 11x10 matrix of cells. Ferranti's quick reference guide provides the following specification:

Total Logic Gates: 900 Max Frequency: 20MHz Gate Delay: 8ns Gate Power: 250uW

See: https://archive.org/details/FerrantiQ.RefULA1984

The die is marked in the top right hand corner:

6566-111 ULA5C052

This die was packed in a 40 pin ceramic DIP, with the markings:

PS 
ULA 
5C052J 
8948


The die size is approximately 4.7mm x 5.0mm.

The photograph itself was created as a panorama using the Hugin application, stitched from 21 photos taken with a Vickers Instruments M14/2 metallurgical microscope with a 32mm (5x) objective lens with a Kenko 1.5X teleconverter on the camera mount.
