Pin Function
Read Strobe Not
Asynchronous read strobe, active Low.
EEPROM Chip Select
This signal is used to select an external EEPROM device.
Asynchronous Ready
ARDY may be used when interfacing asynchronous buses to extend bus access cycles. It
is asynchronous to the host CPU or bus clock. This pin need an external 4.7K pull-up
resistor.
No Connect.
No Connect
Digital IO ground
1.8V regulator output . This 1.8V output pin provides power to pins 38, 43, 57 (VDDA), 63
(VDDAP) and 91 (VDDC) for core VDD supply.
If VDD_IO is set for 1.8V then this pin should be left floating, pins 38, 43, 57 (VDDA), 63
(VDDAP) and 91 (VDDC) will be sourced by the external 1.8V supply that is tied to pins
10, 79, 92, 108 and 125 (VDDIO) with appropriate filtering.
No Connect.
EEPROM Enable
EEPROM is enabled and connected when this pin is pull-up.
EEPROM is disabled when this pin is pull-down or no connect.
Port 1 LED indicator
See the description in pins 3, 4, and 5.
EEPROM Data Out
This pin is connected to DI input of the serial EEPROM.
EEPROM Serial Clock: A 4
(OBCR[1:0]=00 on-chip bus speed @ 125MHz) serial output clock cycle to load
configuration data from the serial EEPROM.
Config Mode: The pull-up/pull-down value is latched as big or little endian mode during
power-up / reset. See “Strapping Options” section for details
EEPROM Data In
This pin is connected to DO output of the serial EEPROM when EEEN is pull-up.
This pin is “don’t care” (no connect) for 32-bit bus mode when EEEN is pull-down (without
EEPROM).
No Connect.
Address Enable
Address and chip select qualifier for the address decoding and chip enable, active Low.
Write Strobe Not
Asynchronous write strobe, active Low.
Digital IO ground
No Connect.
Full-chip power-down. Active Low (Low = Power down; High or floating = Normal
operation). All I/O pins will tri-state during chip power down.
