Differences compared to SDA 525x according to preliminary specification 06/96:
1. RGB-outputs deliver a current instead of a voltage (Pins 45, 46, 47).
2. Instead of FIL1SLC/FIL2SLC/FIL3SLC only FIL3 is needed with changed external
device dimensions (Pin 69). Former FIL1SLC and FIL2SLC remain “not connected”
(Pins 70, 71).
3. LCIN and LCOUT are not needed any more and are now used for RD and WR (see 4.)
4. P-MQFP-80-1 now has RD (Pin 52), WR (53) and PSEN (1) Pins to connect external
RAM.
‘n.c.’ = ‘not connected’ means: Pins must be left open.
