NO. | MIN | MAX | UNIT | ||
---|---|---|---|---|---|
VCCPORL | VCC low supply level when nPORRST must be active during power up | 0.5 | V | ||
VCCPORH | VCC high supply level when nPORRST must remain active during power up and become active during power down | 1.14 | V | ||
VCCIOPORL | VCCIO / VCCP low supply level when nPORRST must be active during power up | 1.1 | V | ||
VCCIOPORH | VCCIO / VCCP high supply level when nPORRST must remain active during power up and become active during power down | 3.0 | V | ||
VIL(PORRST) | Low-level input voltage of nPORRST VCCIO > 2.5 V | 0.2 * VCCIO | V | ||
Low-level input voltage of nPORRST VCCIO < 2.5 V | 0.5 | ||||
3 | tsu(PORRST) | Setup time, nPORRST active before VCCIO and VCCP > VCCIOPORL during power up | 0 | ms | |
6 | th(PORRST) | Hold time, nPORRST active after VCC > VCCPORH | 1 | ms | |
7 | tsu(PORRST) | Setup time, nPORRST active before VCC < VCCPORH during power down | 2 | µs | |
8 | th(PORRST) | Hold time, nPORRST active after VCCIO and VCCP > VCCIOPORH | 1 | ms | |
9 | th(PORRST) | Hold time, nPORRST active after VCC < VCCPORL | 0 | ms | |
tf(nPORRST) | Filter time nPORRST terminal; pulses less than MIN will be filtered out, pulses greater than MAX will generate a reset. Pulses greater than MIN but less than MAX may or may not generate a reset. | 475 | 2000 | ns |
