Power Management
The ispMACH 5000B devices provide unique power management controls. The device has two power settings,
high power and low power, on a per node basis. Low power consumption is approximately 50% of high power con-
sumption with a timing delay adder (tLP) to the routing delay of the low power node. Each node can be congured
as either high power or low power. However, care should be taken when sharing product terms between nodes with
different power settings.
The ispMACH 5000B devices also have a power-off feature for product terms that are not used. By default, any product
term that is not used is congured as such. This allows the device to operate at minimal power consumption without
affecting the timing of the design. For further information on power management, please refer to technical note number
TN1023, Power Estimation in ispMACH 5000B Devices available on the Lattice web site at www.latticesemi.com.
IEEE 1149.1-Compliant Boundary Scan Testability
All ispMACH 5000B devices have boundary scan cells and are compliant to the IEEE 1149.1 standard. This allows
functional testing of the circuit board on which the device is mounted through a serial scan path that can access all
critical logic nodes. Internal registers are linked internally, allowing test data to be shifted in and loaded directly
onto test nodes, or test node data to be captured and shifted out for verication. In addition, these devices can be
linked into a board-level serial scan path for more board-level testing.
sysIO Quick Conguration
To facilitate the most efcient board test, the physical circuit conguration of the I/O cells must be set before run-
ning any continuity tests. As these tests are fast, by nature, the overhead and time that is required for conguration
of the I/Os should be minimal so that board test time is minimized. The ispMACH 5000B family of devices supports
this by offering the user the ability to quickly congure the I/O standard supported by the sysIO cells. This quick
conguration takes milliseconds to complete, whereas it takes seconds for the entire device to be programmed.
Lattice's ispVM System programming software can either perform the quick conguration through the PC parallel
port, or can generate the ATE or test vectors necessary for a third-party test system.
IEEE 1532-Compliant In-System Programming
In-system programming of devices provides a number of signicant benets including rapid prototyping, lower inven-
tory levels, higher quality, and the ability to make in-eld modications. All ispMACH 5000B devices provide in-system
programmability through their Boundary Scan Test Access Port. This capability has been implemented in a manner
