1 MCIMX93-EVK overview
The i.MX 93 Evaluation Kit (MCIMX93-EVK board) is a platform designed to show the most commonly used
features of the i.MX 93 Applications Processor in a small and low-cost package. The MCIMX93-EVK board is
an entry-level development board, which helps developers to get familiar with the processor before investing a
large amount of resources in more specific designs.
MCIMX93-EVK is assembled with two separate boards:
•MCIMX93-SOM: Referred to as "SOM board" in this document
•MCIMX93-BB: Referred to as "Base board" in this document
This document includes system setup and configurations, and provides detailed information on the overall
design and usage of the EVK board from a hardware system perspective.

Part identifier Switch name Description
SW1001 Power button The i.MX 93 applications processor supports the use of
a button input signal to request main SoC power state
changes (that is, ON or OFF) from the PMU.
The ON/OFF button is connected to the ONOFF pin of the
i.MX 93 processor.
•In the ON state:
–If ON/OFF button is held longer than the debounce time,
the power off interrupt is generated
–If the button is held longer than defined max timeout, the
state will transit from ON to OFF, and send PMIC_ON_
REQ signal to turn off the powers of PMIC
•In the OFF state:
–If the ON/OFF button is held longer than the OFF-to-
ON time, the state will transit from OFF to ON, and send
PMIC_ON_REQ signal to turn on the powers of PMIC
SW1002 Reset button (RESET) The button is directly connected to the PMIC PCA9451.
Holding the RESET button forces a reset of the PMIC power

1.11 DIP switches
See Figure 4 for switches position on the board.
Four 4-bit DIP switches (SW1301, SW1005, SW1006, and SW1007) are used on the MCIMX93-EVK board for
signals path selection for the below signals:
•SW1301 is used for Boot Mode configuration. For more detail, see Section 2.5
•SW1005 is used for RFU_BTN1and RFU_BTN2 signals path selection. These signals are used as buttons
(SW1003, SW1004) interrupts. By default, RFU_BTN1 and RFU_BTN2 signals connect with EXP_BTN1 and
EXP_BTN2 from I2C expander (P0_5, I2C address: 0x22).
•SW1006 is used for ENET1_nINTand ENET2_nINT signals, which are used as Ethernet PHY interrupts. By
default, the signals connect with GPIO_IO28 and GPIO_IO29 pins of the target processor.
•SW1007 is used for USB_I2C_SDA and USB_I2C_SCL signals, which are USB-related peripherals
configuration signals of the USB I2C bus. SW1007 connects these signals with I2C1_SDA_BUF and
I2C1_SCL_BUF by default.

2.1 Processor
The i.MX 93 applications processor includes dual Arm Cortex-A55 processors with speeds up to 1.7 GHz
integrated with an NPU that accelerates machine learning inference. The general-purpose Arm Cortex-M33
running up to 250 MHz is for real-time and low-power processing. Robust control networks are possible via
CAN-FD interface. Also, dual 1 Gbit/s Ethernet controllers, one supporting time sensitive networking (TSN),
drive gateway applications with low latency.
The i.MX 93 is useful for applications such as:
•Smart home
•Building control
•Contactless HMI
•Commercial
•Healthcare
•Media IoT
Each processor provides a 16-bit LPDDR4/LPDDR4X memory interface and other interfaces for connecting
peripherals, such as MIPI LCD, MIPI Camera, LVDS, WLAN, Bluetooth, USB2.0, uSDHC, Ethernet, FlexCAN,
and multi-sensors.
For more detailed information about the processor, see the i.MX93 data sheet and i.MX93 Reference Manual at

2.2 Power supply
The primary power supply to the MCIMX93-EVK board is VBUS_IN (12 V - 20 V) through USB Type-C PD
connector (J301).
One system power slider switch M096H-A020RT21A (SW301) is provided to switch ON/OFF the VBUS_IN
supply on the board. Table 1 describes the SW4 configuration.
SW301 switch Description
Pin 1-2 and 4-5 closed VBUS_IN power supply is OFF on the board (default setting)
Pin 2-3 and 5-6 closed VBUS_IN power supply is ON
Table 10. Power switch (SW301) configuration
Two DC buck switching regulators are used:
•MP8759GD (U201) switches VBUS_IN supply to SYS_5V (5 V) power supply, which is input power supply for
PCA9451 PMIC and other discrete devices on the board.
•MP2263GD (U202) switches VBUS_IN supply to VDD_12V (12 V/3A) for MIPI DSI and LVDS backlight.
Note: J201 connector is reserved for power input test. When USB PD charger is not in use, user can provide
15 V power on J201 and short R202 to power up the system (For test purpose only).

2.4 I2C interface
The i.MX 93 processor supports low-power inter-integrated circuit (I2C) module that supports an efficient
interface to an I2C-bus as a master. The I2C provides a method of communication between a number of
devices available on MIMIMX93-EVK board.
One 8-pin dual-row pin header connector (J1005) is provided on the EVK board to support I2C connection. The
developers can use the port for some specific application development.
Table 14 explains the I2C header, J1005, pinout.
Pin Signal name Description
1, 2 VDD_3V3 Power output, 3.3 V
3, 4 I2C1_SCL I2C clock signal, 3.3 V
5, 6 I2C1_SDA I2C data signal, 3.3 V
