System Overview
3-10
U6(Jupiter 4E for ML-2510 and SPGP V3 for ML-2570/2571N)
- ML-2510 use Jupiter4E which has a CPU core CLK with over 150MHz and a System bus 80MHz.
- It use 3.3V for operation voltage and I/O, It uses 80MHz for system bus CLK, Built in Flash Memory.
- ML-2570/2571N use SPGP V3 which has a CPU core CLK with over 400MHz and a System bus 100MHz.
SDRAM
- Main memory. SDCLK is 75Mhz for ML-2510, SDCLIC is 100Mhz for ML-2570/2571N.
A3977
- It is an Main motor driver IC and controls the motion of main motor.
Regulator
- It Supplies the core voltage to CPU by converting 3.3V to 1.8V for ML-2510
EEPROM(U8 : 93C66 for ML-2510, 24C32 for ML-2570/2571N.
