Seiko Epson Corp. announced that its new LCD controller chipthe S1D13751, is integrated with Qualcomm Inc.'s Mobile Display Digital Interface (mddi) technology.

The MDDI standard is a high-speed serial interface solution that directly connects LCD panels and camera modules to the Mobile Station Modem (MSM) chipset, enabling the most advanced, reliable LCD panel and camera technology available today, said the press release. MDDI is also supported by select Qualcomm cdma2000 and W-CDMA (UMTS) solutions.

Commenting on the MDDI technology, Yasumasa Otsuki, managing director and chief executive of the Semiconductor Operations Division for Epson, said, "Its high-speed, low pin count and low power consumption make it an ideal interconnect technology that will strengthen Epson's LCD panel and camera module interfacing product lines for cdma2000 and W-CDMA handsets."

"Qualcomm's MDDI solution is a high-speed, low-power, low-cost interconnect technology that reduces the number of required interconnection wires, shortening development and testing cycles for both OEMs and LCD manufacturers for faster time to market," added Luis Pineda, SVP of marketing and product management for Qualcomm CDMA Technologies.

The MDDI is available on select Qualcomm chipsets, including the MSM6150, MSM6550, MSM6800, MSM7500 and MSM7600 chipsets for cdma2000, and the MSM6275, MSM6280 and MSM7200 chipsets for W-CDMA. According to the press release, previous interface solutions required up to 90 wires, while MDDI requires a minimum of just four wires plus power for bi-directional data transfer that delivers a maximum bandwidth of up to 3.2Gbps.

The S1D13751 advanced LCD controller is a QVGA LCD controller chip that supports Hardware "rotation," "Picture-in-Picture Plus" (a variable size window with overlay functions) and 2D BitBLT. The chip also supports MDDI Type I, with speeds up to 400Mbps and has a dual port 1.3Mpixel camera interface and hardware JPEG encoder/decoder.

First samples of the S1D13751 are expected to be available in the first quarter of 2005.
