1 Overview
NXP EdgeReady MCU-SMHMI solution is a Smart human machine interface (HMI)
hardware and software solution for HMI projects. This solution is implemented using
an NXP platform (SLN-TLHMI-IOT), which is based on NXP i.MX RT117H MCU. This
solution is fully supported by NXP.
This document explains the overall design and usage of the SLN-TLHMI-IOT board
from a hardware system perspective as well as provides recommended optimization
for specific customer products. It also provides advanced system setup and hardware
debugging instructions.
The MCU-SMHMI solution is designed to provide a complete hardware and software
reference for applications that require secured face recognition and local voice control,
for example, coffee machine applications and elevator applications. The main board
and the external modules were carefully selected to achieve optimum performance,
low-power capabilities, and competitive production cost. The board kit includes a “Kit
Content” document, which lists all the accessories that come with the kit.

2.1 i.MX RT117H microcontroller
The i.MX RT117x crossover MCUs are part of the NXP EdgeVerse edge computing
platform, having core frequency up to 1 GHz. This ground-breaking family combines
superior computing power and multiple media capabilities with ease-of-use and real-time
functionality. The dual-core i.MX RT117H MCU runs on the Arm Cortex-M7 core at 1 GHz
and Arm Cortex-M4 core at 400 MHz, while providing advanced security.
2.1.1 Characteristics
The following are some major characteristics of the i.MX RT117H MCU:
•The i.MX RT117H MCU embeds 2 MB on-chip RAM in total, including 512 KB RAM,
which can be flexibly configured as TCM or general-purpose on-chip RAM
•The i.MX RT117H MCU integrates an advanced power management module with DC-
DC and LDO that reduces the complexity of external power supply and simplifies power
sequencing
•Its memory controller supports a wide variety of external modules, including SDRAM
(up to x32), single/dual/quad/octal SPI NOR flash (up to two), HyperRAM/Flash, and
SD cards
•Its interfaces connect peripherals, such as camera sensors, displays, and WLAN or
Bluetooth radio
•Similar to the i.MX processors, the i.MX RT117H MCU embeds rich audio and
video features, including parallel CSI/DSI and MIPI CSI/DSI, graphics accelerator,
microphone PDM input or MQS, and I2S audio interfaces
2.1.2 Boot mode configuration
The i.MX RT117H MCU has four boot modes, with one reserved for NXP use. The boot
mode is selected based on the values stored in bits 1:0 of the BOOT_MODE register of
the MCU, as described in the table below.
BOOT_MODE[1] BOOT_MODE[0] Selected boot mode
0 0 Boot from Fuses
0 1 Serial Downloader
1 0 Internal Boot
1 1 Reserved
Table 5. Boot mode selection
The table below explains how BOOT_MODE register bits 1:0 are mapped to MCU pins /
board signals on the SLN-TLHMI-IOT board.
BOOT_MODE

BOOT_MODE[0] GPIO_LPSR_02 (P6) BOOT_MODE0 SRC_BOOT_MODE00
BOOT_MODE[1] GPIO_LPSR_03 (T7) BOOT_MODE1 SRC_BOOT_MODE01
Table 6. BOOT_MODE register bit - MCU pin mapping
On the SLN-TLHMI-IOT board, MCU boot mode can be controlled using jumper J203, as
shown in the table below.

2.3.1 RGB camera (MIPI-CSI2)
The SLN-TLHMI-IOT board supports an RGB camera module for supplying RGB image
required for display. The camera module has a high-quality, 2 megapixel GalaxyCore
GC2145 UXGA CMOS image sensor.
Data is pushed through a 2-lane MIPI-CSI2 interface. The i.MX RT117H MCU configures
and controls the GC2145 camera via its I2C6 interface, along with two GPIOs that are
used for power-down and reset.
The GC2145 RGB camera is installed on the board through a 30-pin FPC connector
(OK-16M030-04). The figure below shows the circuit diagram of the RGB camera
connector.

Figure 7. GC2145 RGB camera connector
The voltage level of the I2C6 interface and one GPIO from the i.MX RT117H MCU is
3.3 V. To match the GC2145 camera specification, a dual bidirectional voltage-level
translator ON Semiconductor FXWA9306L8X (U1) and a single-bit bidirectional voltage-
level translator Nexperia 74AVC1T45 (U214) are used to translate the voltage level down
to 1.8 V.
Two clock options are available for GC2145 camera: one from CSI_MCLK of i.MX
RT117H, and the other from a 24 MHz low-power crystal oscillator (Y3). The default
option is the 24 MHz oscillator. Switching to CSI_MCLK of i.MX RT117H requires
populating R223 and R238 resistors and removing R239 resistor.
The table below shows signal mapping between the RGB camera sensor GC2145 and
i.MX RT117H MCU on the SLN-TLHMI-IOT board.
