Power measurement jumpers for FVDD (flat panel), BVDD (Bus), 

USBVDD (USB), AVDDOSC (Oscillator I/O ESD), CVDD24 (Core) and 

CVDD13 (SRAM).  Normal operation requires either these jumpers or 

resistors R65, R66, R675, R686, R69 and R70 installed.  Both jumper and 

associated resistor removed when measuring power. 

PLATFORM SETUP INSTRUCTIONS 

The MQ-1132 / NEC 4121 Evaluation Board is used in conjunction with the NEC VR4121 Development 

Platform.  The following components are required and should be included in the NEC VR4121 

Development package: 

§ 

NEC Falcon motherboard + VR4121 CPU module 

§ 

Parallel Cable (installed in J6 which will be under the MQ-1132 evaluation board when installed) 

§ 

Keyboard & PS/2 mouse 

§ 

ATX power supply 

Hardware Assembly 

The NEC VR4121 Development Platform has three connectors, J22, J80 and J36.  These interface to the 

MQ-1132 evaluation board.  The final  assembly should resemble the diagram below which is a side view 

of the NEC VR4121 Platform including the NEC 4121 CPU module and MQ-1132 Evaluation Board. 

Great care should be taken to ensure correct alignment of the sockets and pins to prevent damage during 

assembly. When removing either the MQ1132 board or NEC CPU module, great care should be taken to 

ensure that even pressure is asserted on both sides of the board to prevent bending of the pins.  

Power is supplied to the NEC VR4121 Development Platform  by way of an ATX power supply.  Power 

for the MQ-1132 board is supplied from the NEC VR4121 Platform bus connectors.
