Circuit Description
HD(0:15), data lines and HA(0:23), address lines are connected to memory and YMU765 to communicate.
MV319DNQ(Camera DSP Chip) controls the communication between ARM core and DSP core.
OEn, WEn control the access of memory. KROW, and KCOL recognize the key string input status.
It has J-TAG control pins (TDI/TDO/TCK) for ARM and DSP core. J-SEL signal controls different access to ARM
and DSP core.
ADC(Analog to Digital Convertor) receives the condition of temperature, battery type and battery voltage.
2-2-10. TOH2600DGI4KRA(26MHz)
This system uses the 26MHz TCXO, VC-TCXO-214C6.AFC control signal form PCF5213EL1 controls requency from
26MHz x-tal. It generates the clock frequency. This clock is connected to PCF5213EL1, YMU765 and
MV3315DOQ.
2-2-11. Camera DSP(MV3315DOQ)
MV3315DOQ provides rich video functions up to 30-frame display with minimized tasks in the handset main processor
as well as hardware based real-time JPEG compression and decompression. MV3315DOQ directly transmits and
previews the RGB data to the LCD graphic memory by processing the sensor output data according to the
handset's command. It can save the raw RGB data up to VGA resoultion into its image buffer and allows the
host processor to download with scalable sized compressed data.
It utilizes 16 bit data bus for communication with the main processor, including bus interface types.
2-2-12. KXP74
KXP74 is Tri-axis Orthogonal accelerometers and inclinometers.
The KXP74 utilizes an onboard Serial Peripheral Interface (SPI) for digital communication.
PCF5213EL1 apply KXP74 for G- button and game
