3.3 Design Features
3.3.1 CPU
• Freescale CPU, P1020NSE2HFB (including the security engine) must be used and
configured to operate its core at 800 MHz and DDR3 memory at 667MT/s.
3.3.2 SDRAM
• 256MB DDR3 Memory with two 64x16x8 memory devices and configured in 32 bit
wide with optional ability to increase to 512MB at a future time without PCB re-spin
required.
3.3.3 FLASH
• 32MB parallel NOR Flash in one physical device with optional ability to increase to
64MB at a future time without PCB re-spin required. The device must be Spansion
S29GL256S90TFI020 or compatible and configured in 16 bit wide..
3.3.4 Giga PHY
• The hardware design must be equipped with two Gigabit Ethernet interfaces with
shielded RJ-45 connectors, each designed with one Vitesse VSC8601 (1GbE PHY).
Only one provides PoE. The PHY must support software to control LED functions (link,
activity, etc…) and support software to disable LEDs completely.
3.3.5 CLOCK AND RESET
• A 66.66MHz oscillator will be used to provide the clock for P1020NSE2HFB

• A push button is connected to a GPIO line of the processor to restore to defaults
configurations.
3.3.6 Watchdog Timer
• The hardware design must provide a watchdog circuit, either internal to CPU or by
external logic that should generate a board-wide hardware reset if not ticked in 10 to
20 seconds, provide CPU the status indicating either power-on reset or waterdog reset,
and allow CPU reset this status back to default, power-on reset.
3.3.7 LED function
• The hardware design must support one Board Status LED in Red Green Blue tri-color
to show the status of the AP and each individual color is turned ON/OFF by software
through a GPIO.
• On each Ethernet RJ45, the hardware design should provide two integrated LEDs,
one Green and one Amber and connect Green and Amber LED to LED1 and LED2 of
VSC8601 respectively. Green LED on the left is ON when the link is established and is
Blinking when the link is up and transmitting and receiving and the right Amber LED is
OFF for half duplex or no link and is ON for full-duplex and the link is up. Both LEDs
should be directly controlled by Ethernet PHY and should allow software override to
turn both LEDs OFF either indirectly through PHY registers or directly through GPIOs.

maximum configuration.
• Support for 12V DC power supplied externally via optional country specific AC to DC
adapter kits. The maximum load on DC input must be no more than 15.5W. The 12V
DC adaptors must be compatible with 1.65mm DC jack.
• The design must allow PoE and DC co-existent, but providing power redundancy is
not required.

full system in the configuration of two 3x3 3-stream Radios (both in 5GHz with 80MHz
channel bandwidth), the USB with 500mA-disabled, the LAN w/ PoE ( G1)port served
