Use cases and implementation examples

1. EV (Electric Vehicle) Battery Management System (BMS)

[Use case overview]
The battery of an EV is the heart of the vehicle, and voltage, temperature, charge/discharge status, etc. must be monitored and controlled in real time.
The BMS is a key control unit responsible for optimizing safety, efficiency and lifespan.

[Major features]
Real-time acquisition of cell voltage and temperature using a high-speed ADC
ASIL-D compliant design with safety features (ECC, lockstep)
High-speed data exchange with other ECUs via CAN-FD communication
FLASH MEMORIES for log storage and diagnostic functions

2. Gateway ECU (In-vehicle network integrated control)

[Use case overview]
The gateway ECU, which serves as the core of the in-vehicle network, integrates multiple communication protocols and manages data transfer between each ECU.
This is an important role that requires security and real-time performance.

[Major features]
Supports various communication standards such as CAN-FD, FlexRay, LIN, and Ethernet
Tamper prevention through secure boot and encrypted communication
High-performance architecture supporting simultaneous control of multiple buses
Security infrastructure supporting OTA (Over-the-Air) updates

3. Powertrain control (engine/motor control)

[Use case overview]
Electric and hybrid vehicles require precise torque control of motors and INVERTERS, and control that combines real-time performance with safety is essential.

[Major features]
Motor control with high-speed PWM output
Safety functions support fail-safe design
Timer function for synchronous control between ECUs
Protection control by temperature and current monitoring
