1.1 Overview
The X-STM32MP-MSP01 is powered via a standard 3.3 V supply through the STM32MP157F-DK2 GPIO
connector.
The figure below shows the component placement on the board.
Figure 2. X-STM32MP-MSP01 component placement details
The X-STM32MP-MSP01 interfaces with the main board via an I²C interface along with some GPIO pins for
interrupts. A DIL 24-pin socket is available for additional MEMS adapters and other sensors.
The I²C sensor hub features on the ISM330DHCX are also available by using solder bridges.
The expansion board mounts an LDO to generate 1.8 V for all the MEMS sensors. A level shifter between 1.8

2.3 Level translator: ST2378E
The ST2378E device is an 8-bit, dual supply, bidirectional level translator with ±15 kV ESD protection on I/Os at
VCC side. It is designed to interface data transfer between low voltage ASICs/PLDs and higher voltage systems.
Externally applied voltage, VCC and VL, set logic levels at both sides with the range specified as 1.71 V ≤ VL≤ 5.5
V and VL≤ VCC≤ 5.5 V. For proper operation, VCC should be set higher than VL.
Using a transmission-gate-based design, this device allows bidirectional asynchronous data transfer. This means
that each channel is allowed to have either VCC to VL or VL to VCC data transfer direction independently; no
direction pin is required.
The ST2378E device operates at a guaranteed data rate of 13 Mbps over the entire specified operating voltage
range. The OE pin allows the disable mode operation whereby the current consumption is reduced to less than 1
μA.
