  • Analog Devices - ADP5053 Power management IC
  • Asahi Kasei - AK4950 Audio codec
  • Canon - CK4-1304 Image processor (The Canon Digic 5 is located under the Elpida chip. "The Digic 5 is not the latest and greatest from Canon but for the target market and application of this processor, it represents a good value. For comparative purposes we took a look at the more recent Digic 5+ and found this die to be about 30% smaller. This device is designed by Texas Instruments and Canon, and process clues tell us that it is fabricated at UMC")
