California Micro Devices (NASDAQ: CAMD) announced that the company has developed an innovative display controller architecture that serves both the Mobile Display Digital Interface (MDDI) and Mobile Industry Processor Interface (MIPI) standards for high speed serial display interfaces for use in today’s most advanced mobile handsets. The unique architecture, developed in collaboration with major handset and device manufacturers, will permit advanced handsets that utilize CPUs and application processors with on-chip MDDI compatible hosts to interface with liquid crystal display (LCD) modules that feature either MDDI or MIPI based clients.
The existence of the two standards for high speed serial display interfaces has compelled handset makers to procure different LCD modules which are based on the serial interface standard supported by their selection of CPU architecture. With the development of products based on the new MDDI-to-MIPI bridge architecture, handset makers utilizing a CPU with an MDDI based host will have the flexibility to procure either a display module with an MDDI based client or a MIPI based client. This will allow handset makers that produce models utilizing both MDDI and MIPI based CPUs to satisfy all of their display requirements with modules based on the MIPI standard, resulting in higher volumes and lower module prices.
In addition to providing multi-standard display module support for MDDI based CPU handset designs, products based on the new MDDI-to-MIPI bridge architecture will also be able to interface to existing GSM and WCDMA baseband and application processors via an industry standard CPU interface. This will provide handset makers seeking an early introduction of MIPI based handset designs the flexibility of utilizing widely available GSM and WCDMA CPUs without an integrated MIPI host. Handset makers can reduce product launch risks associated with dependence upon new product development schedules while taking full advantage of the benefits of a high speed serial display interface which include a reduced number of interface signals, lower power consumption and reduced electromagnetic interference (EMI).
“Handset makers that produce systems based on both the GSM and CDMA standards, and associated 3G standards, will have the opportunity to achieve cost savings as a result of concentrating their purchasing power on procuring LCD modules based on a single standard while also enjoying the cost, space, power and EMI reduction advantages inherent in the use of the serial interface,” commented Kyle Baker, CMD’s vice president of marketing.
Products based upon the architecture are expected to be available for sampling in September 2008 with production targeted for March 2009. Details of the new architecture will be presented by CMD at the upcoming SID 2008 International Symposium, Seminar and Exhibition to be held May 20th – 22nd in Los Angeles, California.
