50 / 66 page 50 Altera Corporation MAX 7000 Programmable Logic Device Family Data Sheet Notes to tables: (1) These values are specified under the recommended operating conditions shown in Table 14. See Figure 13 for more information on switching waveforms. (2) This minimum pulse width for preset and clear applies for both global clear and array controls. The tLPA parameter must be added to this minimum width if the clear or reset signal incorporates the tLAD parameter into the signal path. (3) This parameter is a guideline that is sample-tested only and is based on extensive device characterization. This parameter applies for both global and array clocking. (4) These parameters are measured with a 16-bit loadable, enabled, up/down counter programmed into each LAB. (5) The fMAX values represent the highest frequency for pipelined data. (6) Operating conditions: VCCIO = 3.3 V ± 10% for commercial and industrial use. (7) For EPM7064S-5, EPM7064S-6, EPM7128S-6, EPM7160S-6, EPM7160S-7, EPM7192S-7, and EPM7256S-7 devices, 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. (8) The tLPA parameter must be added to the tLAD, tLAC, tIC, tEN, tSEXP, tACL, and tCPPW parameters for macrocells running in the low-power mode. tH Register hold time 1.7 3.0 4.0 ns tFSU Register setup time of fast input 2.3 3.0 2.0 ns tFH Register hold time of fast input 0.7 0.5 1.0 ns tRD Register delay 1.4 2.0 1.0 ns tCOMB Combinatorial delay 1.2 2.0 1.0 ns tIC Array clock delay 3.2 5.0 6.0 ns tEN Register enable time 3.1 5.0 6.0 ns tGLOB Global control delay 2.5 1.0 1.0 ns tPRE Register preset time 2.7 3.0 4.0 ns tCLR Register clear time 2.7 3.0 4.0 ns tPIA PIA delay (7) 2.4 1.0 2.0 ns tLPA Low-power adder (8) 10.0 11.0 13.0 ns Table 36.
