Board Modifications

This section describes modifications to the board to change or add functionality.

Bypassing the USB Programming Interface

The USB programming interface circuit (section 6.2.8 USB Programming and Debug Interface) may be optionally
bypassed by removing the 0 ohm resistors: R3, R4, R7, and R9 (See Schematic Sheet 2 of 4,

Appendix A. Sche-

). Header landing J1 provides JTAG signal access for jumper wires or a 1 x 8 pin header.

Applying External Power

The Breakout Board is powered by the circuit of Schematic Sheet 2 of 4 based on the 5 V USB power source. You
may disconnect this power source by removing the 0 ohm resistors: R47 (VCCO 3.3 V, Bank 0), R48 (VCCO 3.3 V,
Bank 1), and R53 (VCC 3.3 V, Core). Power connections are available from the expansion header landing, J6,
Schematic Sheet 3 of 4.

Measuring Bank and Core Voltages

Test points (TP1, TP2, and TP3) provide access to bank VCCO and VCC core power supplies of the ispMACH
4256V CPLD. 0 Ohm resistors: R47 (VCCO 3.3 V, Bank 0), R48 (VCCO 3.3 V, Bank 1), and R53 (VCC 3.3 V, Core)
can be removed to add a current meter inline or add a resistor shunt to measure voltage across.

Mechanical Specifications

Dimensions: 3 in. [L] x 3 in. [W] x 1/2 in. [H]

Environmental Requirements

The evaluation board must be stored between -40° C and 100° C. The recommended operating temperature is
between 0° C and 90° C.

The board can be damaged without proper anti-static handling.
