C1610 Configuration Note:
HD6 = 0 Demultiplexed Bus
HD7 = 1 16-bit Data Bus
HD8 = 0 WRH- and WRL- control
HD[12:11] = 00b 1Mbyte segment length (A0...A19)
HD15 = 0 CLK divide by 1
HD[9:10]=00b CS3 is GPIO(HRST)
RAM Configuration Note:
Device RAM-P12 RAM-P30
Depth (A0) (A17)
/Width
128Kx16: HA17 VCC (Default)
512Kx16: HA19 HA17
P5.14-15 is read-only inp
PROM Configuration Note:
Depth/Width ROM-P1
256Kx16 N/C
512Kx16 A18
PCB Note:
Provide clearance around PROM
for SMT Sockets
PCB Note:
Stretch RAM pads to
accomodate both 300mil
and 400mil wide devices.
MPGRST- is low after
reset.
MPGRST- must be set high
to access MPEG chip.
