TechInsights Teardown: Hyundai Ioniq 5 head unit
The head unit of the Hyundai Ioniq 5 is a navigation system for the Korean automotive OEM and is used to help vehicles find locations.
The system is integrated into Hyundai vehicles with a touchscreen display that can be used to input addresses or touch icons that automatically finds the address of establishments. The system also allows for calling establishments if a Bluetooth connection is located.
The navigation system consists of a main processor from Intel and multichip memory systems from Micron Technology. An LTE system gives the real-time navigation aspect and updating to alert drivers to accidents and closures in the road.
The following is a partial deep dive into the navigation system from TechInsights.
- 4 GB LPDDR4 SDRAM
- Intel 1.8 GHz dual-core Atom application processor
- Internal 128 GB
Release date: January 2021
Target market: Automotive
The main board of the Hyundai Ioniq 5 head unit includes the Infineon secure microcontroller, Analog Devices’ 3.5 A step-down converter and Monolithic Power systems’ 3-amp step-down converter.
The LTE board allows for the navigation system to communicate with networks to update maps and telematics information. The electronic components found on this board include:
- Multimode, multiband power amplifier, antenna switch and high-band power amplifier module from Skyworks
- Qualcomm’s multimode baseband processor and power management IC
- 512 MB SLC NAND flash and 256 MB mobile LPDDR2 SDRAM from Micron Technology
The CPU board is the heart of the navigation system, which includes the following electronic components:
- Intel’s 1.8 GHz dual-core Atom applications processor
- Renesas’ distributed power unit and programmable multi-channel PMIC
- Samsung’s Multichip memory 2 GB mobile LPDDR4 SDRAM
