26 / 66 page 26 Altera Corporation MAX 7000B Programmable Logic Device Data Sheet Two inverters implement the bus-hold circuitry in a loop that weakly drives back to the I/O pin in user mode. Figure 10 shows a block diagram of the bus-hold circuit. Figure 10. Bus-Hold Circuit PCI Compatibility MAX 7000B devices are compatible with PCI applications as well as all 3.3-V electrical specifications in the PCI Local Bus Specification Revision 2.2 except for the clamp diode. While having multiple clamp diodes on a signal trace may be redundant, designers can add an external clamp diode to meet the specification. Table 13 shows the MAX 7000B device speed grades that meet the PCI timing specifications. Note: (1) The EPM7256B and EPM7512B devices in a -5 speed grade meet all PCI timing specifications for 66-MHz operation except the Input Setup Time to CLK—Bused Signal parameter. However, these devices are within 1 ns of that parameter. EPM7256B and EPM7512B devices meet all other 66-MHz PCI timing specifications. I/O RBH Bus Hold Circuit Drive to VCCIO level Table 13.
