ISP1582
Hi-Speed USB peripheral controller
The RESET_N pin can either be connected to VCC (using the internal POR circuit) or
externally controlled (by the microcontroller, ASIC, and so on). When VCC is directly
connected to the RESET_N pin, the internal pulse width tPORP will typically be 200 ns.
The power-on reset function can be explained by viewing the dips at t2 to t3 and t4 to t5
on the VCC(POR) curve (Figure 8).
t0 — The internal POR starts with a HIGH level.
t1 — The detector will see the passing of the trip level and a delay element will add
another tPORP before it drops to LOW.
t2-t3 — The internal POR pulse will be generated whenever VCC(POR) drops below Vtrip for
more than 11
s.
t4-t5 — The dip is too short (< 11
s) and the internal POR pulse will not react and will
remain LOW.
Figure 9 shows the availability of the clock with respect to the external POR.
7.15 Power supply
The ISP1582 can be powered by 3.3 V
± 0.3 V. For connection details, see Figure 10.
If the ISP1582 is powered by VCC = 3.3 V, an integrated 3.3 V-to-1.8 V voltage regulator
provides a 1.8 V supply voltage for the internal logic.
(1) PORP = Power-On Reset Pulse.
