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.
