3. Hard Ware Specification

3.1 MB91401MB91401 is a network security LSI incorporating a Fujitsu proprietary 32-bit RISC CPU core, 10/100Base-T MAC controller, and encryption and authentication macros. This LSI contains an encryp-tion/authentication hardware accelerator that enables the high-speed processing for encryption/au-thentication communication (IKE/IPsec/SSL). The MAC controller has a packet filtering function that reduces the load on the CPU for an increasing amount of packet processing. In addition, the board has the external interface for high-speed data communication with various external hosts, USB interface as general-purpose interfaces, and various card interfaces, supporting a variety of applica-tions.

3.3 SRAM

4M bytes (1 M × 32 bits) of high-speed SRAM are connected to the CS1 area.• Part number : GS74116TP-10 (GSI Technology.)• Capacity : 4 MB• Bus width : 32 bits• Power supply voltage : +3.3 V• Package : 44-pin TSOP (TSOP (II))

The board uses the HD74LVC139 as a SRAM CS decoder and generates byte-enable signals effec-tive to read mounted high-speed SRAM from WRX (3:0), RDX, and CSX1. Pay attention to the ac-cess timing because these cause control signals (SRAMCSX (3:0), SRAMBEX (3:0), and SRAMWRX) to SRAM to arrive delayed from MB91401 output as shown below.

• CSX : 1.0 ns < tPD < 9 ns• BEXn, WRX : 3.0 ns < tPD < 11 ns

3.8 USB

Series-B type connector which conforms to USB 2.0 FS (12 Mbps) is mounted.The CLK signal for the USB can be supplied selectively either from an external 48 MHz source or from the internal CLK. Use the on-board jumper (J7) to select either.

Figure 12 Connection to MB91401 and resistors

To satisfy USB specification requirements, stop pulling up the D+ line on the device side in order to prevent an incoming current via the D+ line from adversely affecting the device when no voltage is applied to the V-bus with the host and hub off. The board is designed on the assumption that the US-BINS pin of MB91401 inputs the V-bus signal regulated at 3.3 V as an interrupt signal and that D+ is pulled up upon completion of initialization setting for the USB macro in the interrupt routine. This is because it is needed to prevent firmware from pulling up D+ until the end of the initialization rou-tine because the function device must be ready to accept a transaction within 100 ms after the host (hub) senses a port connection (D+ pull-up). This measure is not required when the initialization rou-tine does not require 100 ms. In this case, the V-bus signal can be used to pull-up D+ as it is.The board uses either of the above control signal (UDPUP) from the FPGA or the V-bus signal by jumper-selecting as the D+ pull-up ON/OFF control signal.

3.14 Interrupt

The CPU core of MB91401 has eight external interrupt pins, five of which are used for MB91401 internal interrupts and the other three are connected to the FPGA as external interrupt signal (INT(2:0)) and NMIX pins. The FPGA is input interrupt requests from the extended LAN controller (LAN_INTX) and extended connector (EXT_INTX) and inputs them to MB91401 via FPGA. Inter-rupt signals input to the CPU core are assigned as following table. To set external interrupt enables, interrupt requests, and detection of interrupt requests, use the ENIR (external interrupt enable register), EIRR (external interrupt source register), and ELVR (request level setting register) of MB91401.For interrupt sources from each macro, refer to the relevant manual.

3.15 Reset

The board can generate a hardware reset under the following conditions.• At power ON (power-on reset) • Set SW5 (reset switch) to ON (momentary operation).• Be shorted J17• Reset request from hardware emulator debugger (during use)

If any of these resets occurs, the reset applies to all the devices that have an on-board reset pin. The reset is released (Min) 280 ms after the power supply becomes stable at a power-on reset or after the reset source is removed otherwise.

Figure 18 Reset timing

To use the hardware emulator debugger, set J18 to the "3-2" side to generate PLLRST and system reset signals using the ICERSTX output as the source. For normal use, set J18 to the "1-2" side.

Figure 19 Reset circuit

MB91401 can also generate a software reset by setting the watchdog timer or internal register set-ting. A software reset does not reset to any external device. For details, refer to “MB91401 Hardware Manual”.

3.16 Emulator interfaceThe board has an interface connector for the Fujitsu DSU-FR20/30 emulator (MB2197-01) for eval-uation and verification purposes.For details of the DSU-FR20/30 emulator, refer to the following relevant documents.

• DSU-FR20/30 emulator debugger manual• DSU-FR20/30 emulator debugger hardware manual• DSU-FR20/30 emulator debugger install manual

Note : Power-on and shutdown sequences.• The power-on sequence must be performed in the order described in the DSU-FR20/30 emu-

lator debugger manual. The device malfunction can be caused.

• Once you have turned on the emulator, do not turn off and on the power to the board. The de-vice malfunction can be caused.

• After turning the power on, do not carry or apply shock or vibration to it. The device malfunc-tion can be caused.

• To power on, turn on the host machine → emulator → this board in this order after all oper-ations of the connection is terminated.

• To shut down, turn off this board → emulator → host machine in this order.

3.17 Power supplyThe following 5V/4A switching AC adapter is attached to the board.AC adapter

• Part number: NT24-1S0540 (Akizuki) • Input: 100V 50/60 MHz 50-60 VA • Output: DC 5 V-4 A

Each power supply (3.3 V, 2.8 V, and 1.8 V) is generated by the on-board regulator. The total power supply and current rough estimations by major devices are shown below (The cal-culation for MB91401 assumes about 500 mA).
