Type
Pin Function
30
EEDI
Ipd
EEPROM Data In
This pin is connected to DO output of the serial EEPROM when EEEN is pull-up.
This pin can be pull-down for 8-bit bus mode, pull-up for 16-bus mode or don’t care for 32-
bus mode when EEEN is pull-down (without EEPROM).
31
SWR
Ipd
Synchronous Write/Read
Write/Read signal for synchronous bus accesses. Write cycles when high and Read
cycles when low.
32
AEN
Ipu
Address Enable
Address qualifier for the address decoding, active Low.
33
WRN
Ipd
Write Strobe Not
Asynchronous write strobe, active Low.
34
DGND
Gnd
Digital IO ground
35
ADSN
Ipd
Address Strobe Not
For systems that require address latching, the rising edge of ADSN indicates the latching
moment of A15-A1 and AEN.
36
PWRDN
Ipu
Full-chip power-down. Active Low (Low = Power down; High or floating = Normal
operation).
