USB2PMB1# Adapter Board

Evaluates: Munich (USB2PMB1#)

Detailed Description of Hardware

This Munich board uses the FT2232HL (IC1), a USB

2.0 high-speed (480Mbps)-to-UART/FIFO IC, to process

commands sent by a program running on the PC. Each

particular EV kit has its own custom software specific

to that kit. The operation of this board is USB-to-dual-

channel SPI engine.

27µA low quiescent current, 1.2A efficient PWM step-

down DC-DC converter, MAX1556ETB (IC2). The 5V sup-

ply voltage input for this IC is provided by the Mini-USB

internal oscillator though an LC filter, 4K MICROWIRE

EEPROM (93LC66BT) (IC3). The USB-to-SPI engine

nal logic processes. There is an external 12MHz crystal

across OSCI and OSCO pins of IC1.

Pmod Supply Voltage

The Munich is also designed to supply power to exter-

nal boards (Santa Fe, Campbell, Fresno, and Corona)

through the connector X2. It is intended to provide power

supply to the interface circuitry present in the connected

driver boards.

Figure 3 shows the pin configuration for the SPI-

compatible connector at the USB2PMB1# board.

Figure 4 depicts the pin configuration of connector found

in Santa Fe, Campbell, Fresno, and Corona. The connec-

tor type is female on the USB2PMB1# board and male

type on the drivers.
