MDDI LCD controller brings high-resolution video to portables

San Jose, Calif.—In support of its mobile strategic initiative, Toshiba America Electronic Components Inc. (TAEC) has developed the TC358722XBG Mobile Digital Display Interface (MDDI) LCD controller that delivers VGA (640 x 480 pixels) and WVGA (800 x 480 pixels) display resolutions in portable consumer electronics.

The TC358722XBG features a full-frame buffer capable of displaying 60 frames-per-second in low power mode. It also features an integrated image processor that supports a variety of image processing algorithms (doubling, rotating, mirroring and interpolation), programmable gamma correction and full 24-bit RGB output for the display of up to 60 million colors. The TC3587722XBG can offer a 10Mbit full-frame display buffer to drive a WVGA main display and a secondary display with a QCIF (176 x 144 pixels) resolution, which the company attributes to its embedded DRAM technology that integrates system DRAM directly onto a chip.

The TC3587722XBG device uses a 100-pin P-VFBGA package with a small design footprint (6-mm x 6-mm x 1-mm) for easy implementation in space-challenged environments. The TC358722XBG is compliant to the VESA MDDI Type 1 client interface and supports data rates up to 400-Mbit/s.

The device also supports 8/16/18/24-bit microprocessor interfaces and RGB output in 8/16/18/24-bit formats via an integrated RGB format converter. The TC3587722XBG has SPI and I²C peripheral interfaces and a 32 KHz DPPL system clock that can drive the display even when the MDDI interface is inactive, providing increased power savings. Other peripheral interfaces in the TC358722XBG include a 3-channel PWM signal generator for white LED intensity control and an additional ten general purpose I/O ports.

Pricing: $6.50 per unit in 10K quantities.
Availability: Now.
