Lattice Semiconductor
The number of BIE inputs, thus the number of Power Guard “Blocks” that can exist in a device, depends on the
device size. Table 8 shows the number of BIE signals available in the ispMACH 4000ZE family. The number of I/Os
available in each block is shown in the Ordering Information section of this data sheet.
Table 8. Number of BIE Signals Available in ispMACH 4000ZE Devices
Power Guard for Dedicated Inputs
Power Guard can optionally be applied to the dedicated inputs. The dedicated inputs and clocks are controlled by
the BIE of the logic blocks shown in Tables 9 and 10.

Family.
Global OE (GOE) and Block Input Enable (BIE) Generation
Most ispMACH 4000ZE family devices have a 4-bit wide Global OE (GOE) Bus (Figure 11), except the ispMACH
4032 device that has a 2-bit wide Global OE Bus (Figure 12). This bus is derived from a 4-bit internal global OE
(GOE) PT bus and two dual purpose I/O or GOE pins. Each signal that drives the bus can optionally be inverted.
Each GLB has a block-level OE PT that connects to all bits of the Global OE PT bus with four fuses. Hence, for a
256-macrocell device (with 16 blocks), each line of the bus is driven from 16 OE product terms. Figures 9 and 10
show a graphical representation of the global OE generation.
