AVDP3E
Advanced Video Display processor 3 Enhanced
■ OUTLINE
YGV627 is a VDP (Video Display Processor) that realizes higher resolution, multi-color and high speed drawing
by adopting a synchronous DRAM as the video memory, while maintaining the register compatibility with
YGV617B that is used for controlling the high minuteness On Screen Display (OSD).
Since the device is capable of displaying bitmap images with various resolutions ranging from NTSC to SVGA on
the monitors with any size of screen including wide screen, it can be used for controlling OSD for various display
units. Also, it is capable of representation of varied images in accordance with the application because numerous
number of colors can be selected such as the one in the range from 16 to 65536 RGB color display, or natural image
display using YCbCr.
In addition, the existing system can be up-graded easily thanks to the basic features from YGV617B such as a high
speed drawing function, character drawing function, synchronization with external video signal, digital video input /
output function, and hardware cursor display function.
■ FEATURES
YGV627 is capable of selecting two modes by using the setting of ENH pin.
For convenience, the case of using ENH pin with LOW level (enabled) is referred to as “expansion mode” in this
document. In the expansion mode, all the functions can be used.
The case of using ENH pin with HIGH level (disabled) is referred to as “compatibility mode”. In the compatibility
mode, the software compatibility with YGV617B is maintained, but the functions enhanced for YGV617B cannot
be used. These modes should be used in accordance with the purpose of the application of this device.

■ PIN FUNCTIONS
<CPU interface>
●
D15−
−0 ( I/O: PULL UP )
This is a data bus for connecting with external processor. D15−D8 are not used when the CPU bus with 8 bit type
(when low level is inputted to LWD). At this time, keep the D15−D8 open. These pins are provided with pull-up
resistors respectively.
●
A22−1 ( I )
This is an address bus to be connected with external general purpose microcomputer. In the indirect access mode
(high level inputted to DMAP pin), input to A22−A4 pins are ignored when accessing CSREG space.
In the direct access mode (low level inputted to DMAP pin), input to A22−A8 pins are ignored when accessing
CSREG space.
YGV627 can be used as a YGV617B compatible device when A22 and A21 pins are fixed to low level. Unused pins
must be set to low level or high level.
●
CSREG ( I )
It is a chip select signal input to register space (I/O). When this chip select signal is active, the read / write pulses
inputted are made valid so that the registers in the YGV627 are accessed.
The function of this pin is the same as that of CSIO pin of YGV617B.
●
CSMEM ( I )
This is a chip select signal input pin for video memory port. The read / write pulse inputted while this signal is active
can be used to directly access the video memory controlled by YGV627.
It is possible not to use CSMEM because the video memory can also be accessed from registers. In such case, it is
necessary to input high level to CSMEM pin.
●
A0 / WR1, WR0 ( I )
When chip select input is active, these pins control write access to YGV627.
D15−D8 are controlled by A0 / WR1, and D7−D0 by WR0.
When the CPU is 8 bit type, A0 / WR1 functions as CPU address bit 0.
●
RD ( I )
When chip select input is active, RD controls read access from YGV627.
D15−D0 are in Output State in the period while both this signal and chip select signals are active.
●
READY ( O: PULL UP, 3-state output )
This is data ready signal output to CPU. The READY signal is made low when the internal state of YGV627 is
accessible. READY is a 3-state output. When CSREG or CSMEM (hereafter called CS signals) is not active, it is
high impedance state, and when CS signals is active and RD or WR1, WR0 is not active, high level is outputted
from READY.
Some CPU must use WAIT signal instead of this signal.

WAIT ( O: PULL UP, 3-state output )
This is data wait signal output to CPU. When CS signals is active, the level of WAIT signal is made low once with
respect to RD or WR1, WR0 in accordance with the internal state of YGV627, and in accessible state, it outputs high
level.
When CS signals is not active, it is in high impedance state, and when CS signals is active and RD or WR1, WR0
is not active, high level is outputted from this pin.
Some CPU must use READY signal instead of this signal.

INT ( O: Open drain output )
This is interrupt request signal output to CPU.
This signal is made low when the internal state of YGV627 coincides with the setting conditions of registers.
This signal is reset with access to YGV627’s internal register.
●
INT2 ( O: High speed bus interrupt output )
This is an interrupt request signal output to CPU, and its output logical value is the same as that of INT.
For high speed CPU bus, this output signal is used to avoid the influence of transit time caused by the pull-up resistor
when the interrupt signal is negated.
Use INT or INT2 in accordance with the requirement of the system into which the YGV627 is built-in.
●
LWD ( I: PULL UP )
This is used to select width of CPU data bus.
When this signal is high level input, the device is compatible with 16 bit system and when low level input, the device
is compatible with 8 bit system respectively.
Since LWD is used for selection of a mode, always fix it to either level.
●
RESET ( I: PULL UP, with Schmidt )
Initial reset signal is inputted to RESET. The reset signal input resets the internal state of the device and the internal
registers are cleared to “0”. (Some registers are loaded with initial value.)
Be sure to input the reset signal after power up.
●
DREQ ( O )
DREQ outputs command data request signal to external DMA controller.
●
DACK ( I: PULL UP )
Command data transfer permission signal is inputted to DACK in response to DREQ signal to external DMA
controller.
●
DMAP ( I: PULL UP )
DMAP is used to select a register space mapping method.
When high level is inputted, 16 byte indirect mapping is selected. When low level is inputted, all the registers except
CLUT are mapped directly in the 128 byte space. The input to DMAP determines the valid address when CSREG
signal is active.
DMAP input signal is valid regardless of the state of ENH input signal.
When using YGV627 in YGV617B compatibility mode, input high level to DMAP.
Since DMAP is for selection of a mode, always fix it to either level.
6
YGV627
●
ENH ( I: PULL UP )
This signal permits enhanced functions for YGV617B.
When high level is inputted, only the registers that are compatible with YGV617B are made valid, and the function
of the enhanced registers are fixed to their default values. When low level is inputted, the function of the enhanced
register is made valid.
This pin selects enable / disable of the enhanced functions and determines SDRAM access timing at the same time.
In compatibility mode, the timing of access to SDRAM is equal to that of the performance of YGV617B, but in
enhancement mode, the access performance is doubled.
Since ENH is for selection of a mode, always fix it to either level.
< Video memory interface>
●
BA1−0, VA11−VA0 ( O )
These pins output address for SDRAM that is used as a video memory controlled by YGV627.
They output row address and column address on time sharing basis. BA1 and BA0 output bank address. However,
when VR64 is a high level input (16M bit SDRAM is connected), VA11 becomes bank select.
When a read command or write command is sent to the SDRAM, VA10 functions as auto-precharge enable.
Since these pins are always driven by YGV627, VRAM halt function of YGV617B cannot be used.
●
VD15−VD0 ( I/O: PULL UP )
These pins constitute a data bus for SDRAM that is used as video memory controlled by YGV627.
VRAM halt function of YGV617B cannot be used.
●
RAS ( O )
RAS outputs row address strobe signal for SDRAM that is used as a video memory controlled by YGV627.
Since RAS is always driven by YGV627, VRAM halt function of YGV617B cannot be used.
●
CAS ( O )
CAS outputs column address strobe signal for SDRAM that is used as a video memory controlled by YGV627.
Since CAS is always driven by YGV627, VRAM halt function of YGV617B cannot be used.
●
WE ( O )
WE outputs write strobe signal for SDRAM that is used as a video memory controlled by YGV627.
Since WE is always driven by YGV627, VRAM halt function of YGV617B cannot be used.
●
DQMH, DQML ( O )
These pins output data mask signal for SDRAM that is used as a video memory controlled by YGV627.
DQMH is for VD15 – VD8, and DQML is for VD7−VD0.
●
CS ( O )
This pin outputs chip select signal for SDRAM that is used as a video memory controlled by YGV627.
YGV627 requires connection to SDRAM because the device uses CS control for access to SDRAM for power saving
purpose and against switching noise.
●
SDCLK ( O )
This pin outputs clock for SDRAM that is used as a video memory controlled by YGV627.
Every output signal connected to SDRAM is outputted synchronizing with the rising edge of this clock. The read
data from SDRAM is latched in the YGV627 at the rising edge of this clock. The clock enable pin of SDRAM should
always be used in enable state.

YGV627
●
VR64 ( I: PULL UP )
High level is inputted when the capacity of SDRAM that is used as a video memory controlled by YGV627 is 16M
bits, or low level is inputted when the capacity is 64M bits. This signal determines the function of signal outputted
from BA1, BA0, and VA11–VA0 pins. Connect with the SDRAM as specified below.
Since this pin is for selection of a mode, always fix it to either level.

R, G, B ( O: Analog output )
These pins output linear RGB signal. When a termination resistor of 37.5 Ω is connected, voltage amplitude with
resolution of 8 bits (256 levels) is outputted. These pins can directly drive a monitor whose impedance is 75 Ω as
shown below.

IREF ( I: Analog input )
Reference current for RGB DAC is inputted to this pin. The reference current of – 9.38 mA provides amplitude of
0.7 Vp-p (typical value). When supplying the reference current, use a current sink circuit as shown below.
For the following circuit, adjust the values of R1 and R2 so that the pin potential of IREF (VIREF) become
approximately 1.37 V.

●
VSYNC ( O )
This pin outputs vertical sync signal to external monitor.
●
HSYNC ( O )
This pin outputs horizontal sync signal to external monitor.
●
BLANK ( O )
This pin outputs a signal that indicates non-display period (blank period). Therefore, it can be used as a signal that
indicates valid display period for LCD panel.

●
FSC ( O )
This pin outputs sub-carrier clock for video encoder.
This pin can output a clock inputted to DTCKIN pin divided by 1, 2, 4 or 8 which may be selected in accordance
with the register setting. Inputting a clock of 14.318 MHz into DTCKIN pin provides sub-carrier clock of 3.58 MHz
when divided by 4.
●
DOTCLK ( O )
Output signal of display data (analog R, G, B, DV17−DV0, YS, AT) is outputted synchronizing with DOTCLK.
●
DVOUT ( I: PULL UP )
This pin selects input/output of external video data terminal.
The external video terminal becomes output when low level is inputted to this pin, or input when high level is
inputted to this pin. The input/output of the external video data terminal can be changed with internal register
EXIO(R#05). In such case, input high level to DVOUT or keep it open.
●
DV17−0 ( I/O: PULL UP )
These are input/output pins for digital external video data.
These pins become input when high level is inputted to DVOUT and EXIO(R#05) =“0” is set, or becomes output
when low level is inputted to DVOUT pin or EXIO(R#05) =“1” is set.
For the external video data, a format with 6 bits for digital RGB individually, or a format with 6 bits for CrYCb
individually can be selected.
The format of the input / output data is as shown below.

●
YS ( O )
When performing superimposition, this pin outputs a signal that controls switching with external signal.
When displaying bitmap plane, this pin outputs inversion signal for YSN bits that can be set by dot.
In the border displaying period or blank period, this pin outputs inversion signal of border YS data.
●
AT ( O )
This pin outputs 1 bit attribute data that can be set by display dot. When ATE(R#05) signal of internal register is set
to “0”, the value set in the ATD bit of register is outputted regardless the display data.
When “1” is set for ATE signal, B0 (LSB of Blue) that is inputted to DAC for blue is outputted from AT pin.
At this time, the same data of MSB is inputted to LSB of DAC for blue.
During the blank period, B0 of border is outputted when ATE signal is set to “1”. When the signal is set to “1”, the
value set to ATD bit is outputted.
This signal can be used, for example, for specifying semi-transparency (YM) when externally mixing display data.
●
VSIN ( I: PULL UP )
This signal resets the vertical timing of CRT controller block of YGV627. When this input signal is sampled with
period equal to the pulse width of horizontal sync signal, and low level is detected three times consecutively, the
internal V counter is set at the first HTL timing (horizontal sync signal start timing) immediately after the moment. In
interlace mode, field identification is performed at the resetting of vertical timing by inputting composite sync signal
of external video through this pin. This feature allows the superimposition synchronizing with frame period easily. If
this signal is inputted during the display period, the display data of the next one field is not guaranteed. This pin can
be kept open if this function is not used. The function of this pin is the same as that of VRESET pin of YGV617B.

HSIN ( I: PULL UP )
This signal resets the horizontal timing of CRT controller block of YGV627.
The horizontal timing is set to the horizontal sync starting position at the moment this signal falls from high level to
low level, and at the same time, the phase of dot clock is reset.
When the built-in PLL is operated in the external sync mode, the input signal and output of HSYNC pin are locked.
If this signal is inputted during the display period, the display data of the next line is not guaranteed.
This pin can be kept open if this function is not used.
The function of this pin is the same as that of HRESET pin of YGV617B.
< Clocks>
●
SYCKIN ( I ), SYCKOUT ( O )
Crystal is connected to these pins to generate reference clock that is used in the system.
The built-in PLL produces SDRAM clock based on this clock. When supplying system clock and dot clock using the
same clock through SYSEL pin (when low level is inputted to SYSEL), input the common clock through DTCKIN
pin. At this time, input low level or high level signal into SYCKIN pin. SYCKOUT pin can be kept open.
When inputting externally generated clock, input it into SYCKIN pin.
SYCKIN and SYCKOUT pins are the same as VCKIN and VCKOUT pins of YGV617B.

This signal selects the source of reference clock to be used in the system.
When low level is inputted to SYSEL, the system clock and dot clock use the same source of the clock. In this case,
the common clock is inputted into DTCKIN. Therefore, there is no need to input clock into SYCKIN. When high
level is inputted to SYSEL, SYCKIN pin input is used as the reference system clock independent from the dot clock.
When SYSEL is used with low level input, be sure to input stable clock into DTCKIN even if the clock produced by
the built-in PLL is used as the dot clock. Since SYSEL is used for selection of a mode, always fix it to either level.
This pin has a pull-up resistor.
The function of this pin is the same as that of VCKS pin of YGV617B.
●
DTCKIN ( I ), DTCKOUT ( O )
Crystal is connected to these pins to input dot clock.
When operating the built-in PLL in FSC sync mode, the reference clock is inputted to these pins. At this time, the
clock with multiple of fsc is to be inputted. When PLL function is not used, this input clock is supplied directly to the
CRTC block and displays data control block. When low level is inputted to SYSEL, it is also supplied as the reference
system clock.
When inputted externally generated clock, input it into DTCKIN.
DTCKIN and DTCKOUT are the same as DCKIN and DCKOUT of YGV617B.

●
DPLLVSSR, DPLLRREF, DPLLFILT ( Analog )
These pins are used to connect external resistors and capacitors for the built-in PLL that produces dot clock.
When directly using DTCKIN input signal as dot clock without using the built-in PLL, keep DPLLFILT open and
short-circuit between DPLLRREF and DPLLVSSR.
DPLLFILT
3.3KΩ
220pF
DPLLRREF
3.9KΩ
DPLLVSSR
Notes:
1. Arrange the components so that the parasitic capacitance among DPLLFILT, DPLLRREF and DPLLVSSR is
minimized and the signals do not cross each other.
2. PLL may not lock if there is a time difference between the rising moment of AVDD (for PLL) and the rising
moment of VDD (for Digital Logic).

TEST2-0 ( I: Pull Up )
These pins are used for testing internal circuit of YGV627.
Be sure to keep them open (without connecting any component) when using the device.
●
AVDD1, AVSS1 ( I )
These pins supply power to VCO analog circuit that generates SDRAM clock. Connect +3.3 V to AVDD1 and
ground level to AVSS1.
●
AVDD2, AVSS2 ( I )
These pins supply power to VCO analog circuit that generates dot clock. Connect +3.3 V to AVDD2 and ground level
to AVSS2.
●
AVDD3, AVSS3 ( I )
These pins supply power to analog circuit of RGB DAC section. Connect +3.3 V to AVDD3 and ground level to
AVSS3.
●
VDD, VSS ( I )
These pins supply power to digital circuit of YGV627. Connect +3.3 V to VDD and ground level to VSS. YGV627
has several VDD and VSS, all of which require power supply. Connect a bypass capacitor between VDD and VSS as
a noise killer as close as possible to the pins.
Power supplies, VDD, AVDD1, AVDD2 and AVDD3 are to be turned on at the same time, in principle. Turning on
the power supplies at the same time means that they are to be turned on before the potential difference between them
reaches and exceeds 0.6 V. Avoid making the potential difference 0.6 V or over continuously (over approximately one
second), or the reliability of this LSI may be deteriorated. If the potential difference among the power supplies cannot
be avoided, be sure to turn on/off VDD, AVDD1, AVDD2 and AVDD3 so that their voltages do not exceed VDD.
