LIN-USART Timings at VDD5 = 3.0 to 5.5 V
Conditions during AC measurements
All AC tests were measured under the following conditions:
- IOdrive = 5 mA
- VDD5 = 3.0 V to 5.5 V, Iload = 3 mA
- VSS5 = 0 V
- TA = -40 to TA(max)
- Cl = 50 pF (load capacity value of pins when testing)
- VOL = 0.2 x VDD5,
- VOH = 0.8 x VDD5
- EPILR = 0, PILR = 1 (Automotive Level = worst case)
(VDD5
= 3.0 V to 5.5 V, VSS5 = 0 V, TA = 40°C to TA(max))
* : Parameter m depends on tSCYCI and can be calculated as :
if tSCYCI = 2*k*tCLKP, then m = k, where k is an integer > 2
if tSCYCI = (2*k + 1)*tCLKP, then m = k + 1, where k is an integer > 1
Notes :
The above values are AC characteristics for CLK synchronous mode.
tCLKP is the cycle time of the peripheral clock.
