Here is a polished English translation of the Chinese title: **G32A Automotive MCU Family Expands: G32A1085/1065/1045 Series Now in Mass Production**

ZhuhaiJune 1, 2026 /PRNewswire/ — As automotive electronic and electrical architectures accelerate their evolution toward “central computing + zone control,” the demand for MCUs in edge execution units such as body control, lighting systems, thermal management, and sensor nodes is undergoing a qualitative shift: they must not only meet high-level requirements for functional safety and cybersecurity but also achieve a precise balance among cost, power consumption, and supply chain stability.

As a key new member of the G32A automotive general-purpose MCU family, Geehy officially announces the mass production launch of the G32A1085/1065/1045 series — high-reliability automotive general-purpose MCUs based on the Arm^® Cortex^®-M0+ core.

1× CAN (supports CAN 2.0A/B and CAN FD)
Up to 55 I/O pins, all mappable to external interrupt vectors

Functional Safety and Cybersecurity
The G32A1085/1065/1045 series builds safety capabilities into the hardware foundation:
Functional Safety: MPU, CRC, Independent Watchdog, Clock Monitor, Full Flash/SRAM ECC
Cybersecurity: TRNG True Random Number Generator, AES256 Encryption Module, SHA256 Hash Function, 96-bit Unique ID

This means that from code storage to data transmission, and from key generation to identity authentication, the G32A1085 provides hardware-level protection, significantly reducing the burden of software security development.

Software Ecosystem: Dual-Version SDK, Balancing Quality and Efficiency

Geehy provides two complete Software Development Kits for the G32A1085/1065/1045 series to meet the requirements of different project stages and quality systems.

Fully Domestic Supply Chain: From Design to Packaging and Testing, Self-Controlled

The G32A1085/1065/1045 series achieves a complete domestic closed-loop supply chain from chip design and wafer fabrication to packaging and testing. This means not only more stable production capacity and predictable delivery cycles, along with more efficient localized technical support and rapid response. Moreover, against the backdrop of the accelerating adoption of domestic automotive-grade chips, the G32A1085/1065/1045 series offers customers a safe and reliable MCU supply chain option.

Three Mass-Production Reference Solutions: Shortening the Distance from Evaluation to Production

Geehy has developed three complete reference design solutions based on the G32A1085, all of which have passed functional testing.

Solution 1: Ultrasonic Reverse Radar Solution

• Integrates multiple timer modules for controlling the transmission and reception of ultrasonic reverse radar waves, meeting the stringent requirement of simultaneous transmission and reception of 8 channels without data loss.
• Integrates power supply monitoring, enabling timely response to undervoltage/overvoltage faults via ADC sampling.
• The system uses a CAN bus expansion interface with customizable algorithm interfaces. Developers can flexibly add functions such as custom distance thresholds, alarm logic adjustment, multi-device linkage, and OTA upgrades based on the main controller.
• Equipped with a high-performance computing core, it performs software multi-stage filtering, temperature compensation, clutter rejection, and distance calibration on the raw echo data uploaded by 8 channels of GURC01. Uses the dedicated GURC01 ultrasonic module to simplify hardware architecture and reduce BOM cost.

Solution 2: Vehicle Refrigerator Control Solution

• Significantly reduces the risk of runaway operation and post-sale failures through mechanisms such as multi-dimensional detection, fault grading, watchdog, startup protection, and lockout shutdown, meeting automotive-grade safety requirements.
• Employs Boot verification, parameter CRC, permission control, and upgrade traceability to prevent illegal parameters and abnormal firmware injection, ensuring system operational integrity.
• Utilizes highly integrated peripherals, reduces external components, and enables platform parameter reuse, effectively lowering BOM cost, PCB area, development and maintenance costs, enhancing product competitiveness.
• Integrates DTC, freeze frame, online upgrade, and production test diagnostic capabilities, significantly improving mass production testing efficiency and post-sale fault location speed, shortening maintenance cycles.

Solution 3: Automotive ADB Headlight Solution

• Focuses on essential peripherals for the headlight execution end (communication, SPI, CAN, GPIO, Timer, diagnostics, basic lighting effects), avoiding excessive computing power to reduce BOM and software complexity.
• Integrates watchdog, fault input, ADC sampling, communication checksum, timeout protection, and state machine safe shutdown. Critical states are traceable, and power and communication links feature fault detection and protection.
• Provides a companion lightweight MCAL with reliable and standardized code, accelerating mass production adoption.
