Geehy Launches G32A1425 Arm Automotive MCU for Body and Comfort Systems

Geehy has unveiled the G32A1425, a new automotive-grade microcontroller designed specifically for body control modules and comfort applications in new energy vehicles (NEVs).

This device belongs to the G32A14xx family and is built on a 40 nm process. It features an Arm Cortex-M4F core with hardware floating-point unit, running at up to 112 MHz (80 MHz guaranteed at 125°C ambient for full Grade 1 operation).

Key Specifications and Features

• Memory: 256 KB Flash (including 64 KB data flash with ECC) + 32 KB SRAM + 4 KB configurable non-volatile memory (SRAM/EEPROM mode)
• Connectivity: Three CAN controllers with CAN FD support, three LPUARTs, three LPSPI, one LPI2C
• Analog: Two 12-bit ADCs, comparator with 8-bit DAC
• Timers: Four 16-bit GPTs, low-power timers, RTC
• Safety & Security: ISO 26262 ASIL-B ready, AEC-Q100 Grade 1 (-40°C to 125°C), ECC on memories, MPU, watchdogs, CSEc security block with crypto and unique ID
• Power: ~378–390 µA/MHz, low-power stop mode ~57.5 µA at 25°C

Target Applications

The G32A1425 is ideal for cost-sensitive, defined-function ECUs at the vehicle edge, including:

• Window, door, and seat control modules
• Lighting and wiper systems
• Low-voltage battery management nodes
• On-board charger auxiliaries and DC-DC supervision

With rich peripheral integration and strong automotive certifications, it helps reduce external components, board space, and overall system cost while meeting modern safety and network demands in NEVs.

The MCU supports AUTOSAR compatibility (e.g., Vector MICROSAR), making it easier for Tier 1 suppliers to integrate into existing development flows.

This launch strengthens Geehy’s growing portfolio of automotive-grade solutions focused on body electronics and functional safety.
