Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SCLK_TX | input | SPI transmit clock from the microcontroller to the MC33664, up to 2.0 MHz, with logic levels referenced to VIO (max VIO + 0.3 V). |
| 2 | CSB_TX | input | SPI transmit chip select from the microcontroller to the MC33664, with an internal 100 kΩ pull-up. |
| 3 | DATA_TX | input | SPI transmit data from the microcontroller to the MC33664, with an internal 100 kΩ pull-down. |
| 4 | EN | input | Enable control pin for the MCU to put the MC33664 into Sleep mode (EN = 0) or Normal mode (EN = 1), with an internal 100 kΩ pull-down. |
| 5 | SCLK_RX | output | Message receive SPI clock output to the microcontroller, up to 2.0 MHz. |
| 6 | CSB_RX | output | Message receive SPI chip select output to the microcontroller. |
| 7 | DATA_RX | output | Message receive SPI data output to the microcontroller. |
| 8 | INTB | output | Digital interrupt pin used to trigger MCU wake-ups, giving a 100 µs verification pulse after EN goes from LOW to HIGH. |
| 9 | VIO | power_in | Digital 3.3 V/5.0 V power supply to the IC, with a normal operating range of 3.1 V to 5.5 V and an absolute maximum of 7.0 V. |
| 10 | DGND | power_in | Digital ground, the reference for the VIO and logic pins. |
| 11 | GNDT | power_in | Terminate to ground. |
| 12 | GNDS | power_in | Substrate ground; terminate to ground. |
| 13 | RDTX- | bidirectional | Transformer communication bi-directional bus pin, with a ±10 V absolute maximum rating. |
| 14 | RDTX+ | bidirectional | Transformer communication bi-directional bus pin, with a ±10 V absolute maximum rating. |
| 15 | AGND | power_in | Analog ground, the reference for the VCC5 supply and bus pins. |
| 16 | VCC5 | power_in | 5.0 V input supply, with a fully operational range of 4.75 V to 5.5 V and an absolute maximum of 7.0 V. |
