NO. | MIN | MAX | Unit | ||
---|---|---|---|---|---|
VCCPORL | VCC low supply level when PORRST must be active during power up | 0.5 | V | ||
VCCPORH | VCC high supply level when PORRST must remain active during power up and become active during power down | 1.35 | V | ||
VCCIOPORL | VCCIO / VCCP low supply level when PORRST must be active during power up | 1.1 | V | ||
VCCIOPORH | VCCIO / VCCP high supply level when PORRST must remain active during power up and become active during power down | 3 | V | ||
VIL(PORRST) | Low-level input voltage of PORRST VCCIO > 2.5V | 0.2 VCCIO | V | ||
Low-level input voltage of PORRST VCCIO< 2.5V | 0.5 | V | |||
3 | tsu(PORRST) | Setup time, PORRST active before VCCIO and VCCP > VCCIOPORL during power up | 0 | ms | |
6 | th(PORRST) | Hold time, PORRST active after VCC > VCCPORH | 1 | ms | |
7 | tsu(PORRST) | Setup time, PORRST active before VCC <= VCCPORH during power down | 8 | µs | |
8 | th(PORRST) | Hold time, PORRST active after VCCIO and VCCP > VCCIOPORH | 1 | ms | |
9 | th(PORRST) | Hold time, PORRST active after VCC < VCCPORL | 0 | ms | |
tf(PORRST) | Filter time PORRST, pulses less than MIN will be filtered out, pulses greater than MAX are guaranteed to generate a reset(1) | 20 | 150 | ns | |
tf(RST) | Filter time RST, pulses less than MIN will be filtered out, pulses greater than MAX are guaranteed to generate a reset | 20 | 150 | ns |
NOTE
There is no timing dependency between the ramp of the VCCIO and the VCC supply voltage; this is just an exemplary drawing. All requirements are to ensure PORRST is active when VCCIO or VCC is out of the normal operating range.
