MAX 7000B Programmable Logic Device Family Data Sheet
Preliminary Information
Notes to tables:
(1)
These values are specified under the Recommended Operating Conditions in
Table 12 on page 25
.
(2)
MAX 7000B timing values are preliminary.
(3)
These values are specified for a PIA fan-out of one LAB (16 macrocells). For each additional LAB fan-out in these
devices, add an additional 0.1 ns to the PIA timing value.
(4)
Measured with a 16-bit loadable, enabled, up/ down counter programmed into each LAB.
(5)
The
f
MAX
values represent the highest frequency for pipelined data.

Power
Consumption
Supply power (P) versus frequency (
f
MAX
, in MHz) for MAX 7000B
devices is calculated with the following equation:
P = P
INT
+ P
IO
= I

IO
The P
IO
value, which depends on the device output load characteristics
and switching frequency, can be calculated using the guidelines given in
Application Note 74 (Evaluating Power for Altera Devices)
.
The I
CCINT
value depends on the switching frequency and the application
logic. The I
CCINT
value is calculated with the following equation:
I
