[Drawing functions]
q Commands
Block transfer by word (CPU to VRAM, VRAM to CPU, VRAM to VRAM)
Font drawing, dot drawing and rectangular drawing.
q Drawing attribute Sets drawing clip area, drawing offset or drawing page, and designates bit mask, color mask,
logical operation (NOT, AND, OR, EOR etc.), or direction of transfer.
[Operational clock]
q System clock (clock for drawing system):
q Dot clock (clock for display system):
up to 33 MHz
up to 40 MHz
[CPU interface]
q 16 bit or 8 bit asynchronous interface
q Provided with a video memory space up to 8M bytes and internal register space of 128 bytes.
q The video memory space and internal register space can be mapped indirectly with 16 byte registers.
q Built-in data buffer for memory space access and built-in data FIFO for drawing commands
q CPU interruption based on various conditions of display and drawing
q DMA transfer of drawing command data can be made when connected with external DMA controller
[Video memory interface]
q Connected memory:
16M bit SDRAM (512k words X 16 bits X 2 banks) 1 piece
or 64M bit SDRAM (1M words X 16 bits X 4 banks) 1 piece
q SDRAM clock:
up to 66 MHz (System clock multiplied by 2 or 4)
q Built-in FIFO for display data improves the drawing access efficiency and realizes high speed drawing.
[Monitor interface]
q Analog RGB output with built-in DAC (8 bits for RGB individually)
q Digital video input / output (6 bits for RGB individually)
q Equipped with sub-carrier clock output, dot clock output, sync signal output, YS and attribute output pins.
[Others]
q Package: 176LQFP (YGV627-V)
q CMOS, 3.3V single power supply
q Operating temperature range: −40 to +85 °C
Supplementary information:
For YGV627, Application Manual that details the specifications of the device and the evaluation board
(MSY627DB01) are available in addition to this brochure.
The evaluation board is equipped with an SDRAM of 8 MB as a video memory. A high performance system can
be realized when it is used with Hitachi’s CPU board, Super H Solution Engine.
The device driver provided by Yamaha and attached to the evaluation board
consists of the main body of the driver and API related layers, allowing the
user to build it into the system easily according to the environment.
For the details of these products, inquire of the sales agents or our business
offices.
For CPU board, inquire of: Hitachi ULSI Systems Co., Ltd.
