ZHCSO45 October 2021 TCAN1044AEV-Q1
PRODUCTION DATA
The TCAN1044AEV-Q1 logic I/Os support CMOS levels with respect to VIO for compatibility with MCUs that support 1.8-V, 2.5-V, 3.3-V, or 5-V systems.
| Device Mode | TXD Input(2) | Bus Outputs | Driven Bus State(2) | |
|---|---|---|---|---|
| CANH | CANL | |||
| Normal | Low | High | Low | Dominant |
| High or open | High impedance | High impedance | Biased recessive | |
| Standby | X | High impedance | High impedance | Biased to ground |
| Device Mode | CAN Differential Inputs VID = VCANH – VCANL | Bus State | RXD Pin |
|---|---|---|---|
| Normal | VID ≥ 0.9 V | Dominant | Low |
| 0.5 V < VID < 0.9 V | Undefined | Undefined | |
VID ≤ 0.5 V | Recessive | High | |
| Standby | VID ≥ 1.15 V | Dominant | High Low if a remote wake event occurred See Figure 8-5 |
| 0.4 V < VID < 1.15 V | Undefined | ||
| VID ≤ 0.4 V | Recessive | ||
| Any | Open (VID ≈ 0 V) | Open | High |
