Building on the G32A1445/1465 platform, Geehy introduces the G32A1425 series: a streamlined, high-efficiency automotive general-purpose MCU. Optimized with a "golden memory combination" of 256KB Flash and 32KB SRAM, it delivers excellent cost-performance for applications with defined functionality and moderate memory needs. It targets entry-level automotive electronics, offering an ideal solution for body control and comfort system modules in new energy vehicles.

Focused Resources for Reliable Performance

The G32A1425 keeps essential configurations and features an Arm® Cortex®-M4F core with FPU, running up to 112MHz. Built to automotive-grade standards, it ensures high performance, safety, and reliability, with strong ESD/EMMC immunity. Operating stably from -40°C to 125°C, it supports high-precision timers, rich communication interfaces (CAN-FD, LIN, SPI), and analog peripherals. This MCU handles body control logic, data acquisition, communication, and small-motor drives efficiently, without wasting performance.

Precisely Targeted Scenarios for Broad Application

The G32A1425 series fits multiple automotive applications:

• Body Control Domain: Modules such as power windows, door locks, mirrors, wipers, and basic lighting simplify ECU design with high integration and reliability.

• Comfort and Auxiliary Systems: Drives air-conditioning fans, seat control, and low-power in-vehicle pumps, enhancing the driving experience.

• Electronic Control Systems: Acts as a slave unit for low-voltage BMS, OBC auxiliary control, and DC-DC converter management in defined subsystems.

• Intelligent Sensor Nodes: Supports rain/light sensors, TPMS, and similar devices for data acquisition and processing.

Comprehensive Production-Ready Ecosystem for Reliable Development Foundation

The G32A1425 inherits the G32A family’s mature software and hardware support, ensuring smooth development and production:

• Automotive-grade development: Compliant with ASPICE and ISO 26262 ASIL-B standards.

• Complete tool-chain: Free driver source code, EB configuration tools, and compatibility with major BSW like Vector.

• Efficient development and migration: Easy debugging, platform porting, and smooth upgrades from existing designs, reducing complexity, shortening cycles, and lowering costs while ensuring automotive-grade safety.

The series also offers full development support for fast, high-quality deployment. Compatible with mainstream IDEs such as KEIL and IAR, it allows leveraging existing hardware for rich functionality with excellent performance. Geehy provides evaluation boards, complete SDKs, hardware reference designs, and detailed technical documentation to accelerate time-to-market.
