Notes to Table 3–17:
(1) This design is a binary loadable up counter.
(2) This design is configured for read-only operation in Extended mode. Read and write ability increases the number of logic elements (LEs) used.
(3) This design is configured for read-only operation. Read and write ability increases the number of LEs used.
(4) This design is asynchronous.
(5) The I2C megafunction is verified in hardware up to 100-kHz serial clock line rate.
Internal Timing Parameters
Internal timing parameters are specified on a speed grade basis independent of device
density. Table 3–18 through Table 3–25 on page 3–19 list the MAX V device internal
timing microparameters for LEs, input/output elements (IOEs), UFM blocks, and
MultiTrack interconnects.
f For more information about each internal timing microparameters symbol, refer to
AN629: Understanding Timing in Altera CPLDs.
