Circuit Description
2-2-9. PCF5212EL1
The PCF5212EL1 is mainly composed of embeded DSP and ARM core. The DSP subsystem includes the Saturn
DSP core with embedded RAM and ROM, and a set of peripherals. It has 24kx16 bits PRAM, 104k*16 bits,
32k*16 XYRAM and 63k*16 XYROM in the DSP.
The ARM946E-S consists of an ARM9E-S processor core, 8 kbyte instruction cache and 8 kbyte data cache,
tghtly-coupled ITCM(Instruction Tightly Coupled Memory) and DTCM(Data Tightly Coupled Memory) memories, a
memory protection unit, and an AMBA(Advanced Microcontroller Bus Architecture) AHB(Advanced
High-performance Bus) bus interface with a write buffer.
HD(0:15), data lines and HA(0:23), address lines are connected to KBJ10KB00M (memory), MV319DNQ (image dsp)
and YMU765 (melody IC). It has 64 kbyte SC RAM (0.5 Mbit) and 32 kbyte SC program ROM for bootstrap
loader in the ARM core.
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. TCO-5888T (26MHz)
This system uses the 26MHz TCXO, TCO-5871U, Toyocom. AFC control signal form PCF5212 controls
frequency from 26MHz x-tal. It generates the clock frequency. This clock is connected to PCF5212, YMU765 and
UAA3587.
2-2-11. Multimedia Chip (CL8522S5)
CL8522S5 is the hardware based MPEG4 CODEC is available to capture the video signal of up to CIF Resolution
(352X288, at 30FPS). CL8522S5 directly transmits and previews the RGB Data to the LCD graphic memory by
processing the sensor output data. It can save the raw RGB data up to 1600x1200 into its image buffer and allows the
host processor to download with scalable sized compressed data.
