Notes to Table 1–1:

(1) t_PD1represents a pin-to-pin delay for the worst case I/O placement with a full diagonal path across the device and combinational logic

implemented in a single LUT and LAB that is adjacent to the output pin.

(2) The maximum frequency is limited by the I/O standard on the clock input pin. The 16-bit counter critical delay will run faster than this number.

For more information about equivalent macrocells, refer to the MAX II Logic Element to

Macrocell Conversion Methodology white paper.

MAX II and MAX IIG devices are available in three speed grades: –3, –4, and –5, with

–3 being the fastest. Similarly, MAX IIZ devices are available in three speed grades: –6,

–7, and –8, with –6 being the fastest. These speed grades represent the overall relative

performance, not any specific timing parameter. For propagation delay timing

numbers within each speed grade and density, refer to the DC and Switching

Characteristics chapter in the MAX II Device Handbook.

Table 1–2 shows MAX II device speed-grade offerings.
