EPD interface
The IMXEBOOKDC5 board electrophoretic display (EPD) interface provides three FPC/FFC connectors for plugging in an e-paper display. These connectors are connected to the EPDC board-to-board connector J15 on the board, allowing the e-paper display to be controlled from the i.MX 8ULP processor on the MCIMX8ULP-EVK board.
The IMXEBOOKDC5 board comes with an e-paper display (E Ink VB3300-FOC) mounted on the front (top) side of the board, with the help of the three EPD interface connectors, which are placed on the back (bottom) side of the board. For more information on VB3300-FOC, see VB3300-FOC/ED060XH7 data sheet.
The three EPD interface connectors are listed in Table 9.

The IMXEBOOKDC5 board uses a 20-bit bidirectional voltage translator U2 (Nexperia 74AVCH20T245DGG,11)
for shifting voltage levels of signals between the processor and the e-paper display.
At U2, voltage level of processor signals can be 1.8 V (default setting) or 3.3 V. Voltage level of processor signals can be controlled through the settings of the 2-pin jumpers J8 and J19
Similarly, voltage level of e-paper display signals can be 1.8 V or 3.3 V (default setting). Voltage level of e-paper display signals can be controlled through the settings of the 2-pin jumpers J20 and J21.
Table 13 shows how to select the I/O voltage for processor signals at U2.
| Jumper settings | Processor signal I/O voltage | Applicable for (board) |
| J8 is shorted and J19 is open | 3.3 V | Legacy EVK boards |

Alternative EPD interface
Apart from the EPD interface described in Section 2.3, the IMXEBOOKDC5 board provides an alternative EPD interface, which includes the following three connectors (none of them is populated by default):
- 20-pin EPD header J14
- 20-pin EPD header J17

I2C interface
The Inter-Integrated Circuit (I2C) protocol is a serial bus protocol that allows multiple peripheral devices to communicate to one or more master devices with a pair of control and data signals.
The IMXEBOOKDC5 board devices are configured through an I2C bus of the main board processor. If MCIMX8ULP-EVK is used as the main board, then, the LPI2C1 bus of the i.MX 8ULP processor acts as the I2C master for the IMXEBOOKDC5 board devices.
Table 18 shows the IMXEBOOKDC5 I2C devices.

- A 7-bit address does not include the read/write (R/W) bit.
- I2C address depends on the plugged-in e-paper display.
I2C-to-GPIO expander
The IMXEBOOKDC5 board has a general-purpose input/output (GPIO) expander that provides remote I/O expansion via the I2C bus interface.
Table 19 describes the IMXEBOOKDC5 I2C-to-GPIO expander
Table 19. I2C-to-GPIO expander
