IC801 VHIMN6627933C: CD Digital Signal Processor (MN6627933C) (2/2)
In this unit, the terminal with asterisk mark (*) is (open) terminal which is not connected to the outside.
NOTE: Signals with * are switched to other signals by microcomputer command.
DRAM pins differ in specifications depending on the type and capacity.
NOTE: When sharing the PCB with MN6627932, connect pins as follows:
No. 62 pin (N.C. pin) = L (fixed), No. 54 pin (N.C. pin): LOVDD2, No. 65 pin (N.C. pin): LOVSS2
Refer to the MN6627932 specifications for the product details.
