28 / 52 page ![]() FullFlex Document Number: 38-06082 Rev. *K Page 28 of 52 Table 15. Master Reset Timing Parameter Description -200 -167 Unit Min Max Min Max tPUP Power-up time 1 – 1 – ms tRS Master reset pulse width 5 – 5 – cycles tRSR Master reset recovery time 5 – 5 – cycles tRSF Master reset to outputs inactive/Hi Z – 15 – 18 ns tRDY[54] Master reset release to port ready – 1024 – 1024 cycles tCORDY[55] C rise to port ready – 9.5[56] –11[56] ns Table 16. JTAG Timing Parameter Description -200 -167 Unit Min Max Min Max fJTAG JTAG TAP controller frequency – 20 – 20 MHz tTCYC TCK cycle time 50–50– ns tTH TCK high time 20 – 20 – ns tTL TCK low time 20–20– ns tTMSS TMS setup to TCK rise 10 – 10 – ns tTMSH TMS hold to TCK rise 10–10– ns tTDIS TDI setup to TCK rise 10 – 10 – ns tTDIH TDI hold to TCK rise 10 – 10 – ns tTDOV TCK low to TDO valid – 10 – 10 ns tTDOX TCK low to TDO invalid 0 – 0 – ns tJXZ TCK low to TDO high Z – 15 – 15 ns tJZX TCK low to TDO active –15–15 ns tJZX TCK low to TDO active –15–15 ns . Notes 54. READY is a wired OR capable output with a weak pull-down. For a decreased falling delay, connect a 250- resistor to VSS. 55. Add this propagation delay after tRDY for all Master Reset Operations. 56. Add 15% to this parameter if a VCORE of 1.5 V is used. [+] Feedback |
