5.3.3.1 Reset and Discovery Response Timing
Parameter and Condition(1) | Sym. | Min. | Max. | Units | |
---|---|---|---|---|---|
Reset Low Time, Device in Inactive State(4) | tRESET | 96 | — | µs | |
Reset Recovery Time(4, 6) | Clock Divider = 1x | tRRT | 1000 | — | µs |
Clock Divider = 2x | 1200 | — | µs | ||
Clock Divider = 4x | 1800 | — | µs | ||
Discovery Response Request(4) | tDRR | 1 | 2 – tPUP(2) | µs | |
Discovery Response Acknowledge Time(5) | tDACK | 2 | 6(3) | µs | |
Host Strobe Discovery Response Time(4) | tMSDR | tRD + tPUP(2) | 2 | µs | |
SI/O High Time for Start/Stop Condition(4) | tHTSS | 150 | — | µs |
Note:
- AC measurement conditions for the table above:
- All parameters are production tested unless otherwise noted.
- Loading capacitance on SI/O: 100 pF
- VPUP: Applied at minimum and maximum VCC
- tPUP is the time required to be pulled up from VIL to VIH when the SI/O line is released. This value is application-specific and is a function of the loading capacitance on the SI/O line as well as the RPUP chosen.
- Microchip’s AT21CS11 supports a maximum of 24 µs and a minimum of 8 µs.
- The host system must ensure the parameter timing values are met.
- The ECC204-TFLXAUTH ensures by design this timing parameter is met.
- Parameter is ensured through characterization but is not production tested.
