New Product Recommendation: GigaDevice Launches the GD33AP236x Series Automotive‑Grade SBCs
In response to the design requirements of automotive electrical systems for system‑level base chips (SBCs) in terms of integration, reliability, and interface compatibility, GigaDevice has launched the GD33AP236x series of automotive‑grade SBC products. This series integrates an LDO, a power management unit (PMU), and CAN FD and LIN transceivers on a single chip, while meeting the AEC‑Q100 Grade 1 automotive qualification standard. It is suitable for mainstream automotive applications such as body domain controllers (BDCs), body control modules (BCMs), lighting control modules, and HVAC controllers. The GD33AP236x SBCs can be paired with GigaDevice’s GD32A5x and GD32A71x automotive‑grade MCUs to form system‑level power and communication control solutions, further expanding the company’s product portfolio in the automotive electronics market.
Currently, automotive electrical and electronic architectures are steadily advancing toward domain‑control and integration. As a result, in‑vehicle control modules face increasingly stringent requirements for power‑supply stability, communication reliability, power‑consumption management, and functional safety levels. Traditional discrete‑component solutions suffer from high component counts, large PCB footprints, and issues such as limited compatibility and weak fault‑protection capabilities. GigaDevice’s GD33AP236x series aligns with mainstream industry specifications, featuring an upgraded power‑delivery architecture, enhanced communication interfaces, and an advanced safety‑monitoring system, thereby meeting the design standards of next‑generation vehicle body ECUs.
Multiple flexible voltage outputs, compatible with a wide range of power supply applications.
The GD33AP236x series integrates three configurable LDOs, with a power‑supply architecture that is compatible with mainstream products on the market. It also features optimized load‑matching capabilities, ensuring stable power delivery across multiple voltage domains in automotive applications.
LDO1: The primary regulated output, providing a 5 V supply and supporting a 3.3 V–powered variant, with a maximum current drive capability of 250 mA, primarily supplying the core power to automotive‑grade MCUs.
LDO2: Auxiliary regulated output, providing a 5 V supply with a maximum output current of 100 mA. It features integrated external protection circuitry and is suitable for powering automotive sensors and peripheral devices.
LDO3: Offers multiple selectable output voltages, supporting either a 5V/3.3V or a 3.3V/1.8V configuration. It can be paired with an external PNP transistor to implement either load‑sharing with the main supply VCC1 or independent power‑supply operation, and it also features protection functions for off‑board applications.
Advantage
1. Combines excellent performance and supports a wide range of body control applications.
The GD33AP236x series combines multiple outstanding features, including communication, security, and power‑consumption management, and is suitable for a wide range of body‑control applications.
2. Integrates standard high-speed communication interfaces and is compatible with mainstream in-vehicle bus protocols.
It integrates a high-speed CAN transceiver that supports the CAN FD protocol, with a maximum data rate of 5 Mbps and compliance with multiple international industry standards. It also incorporates multiple LIN transceivers to accommodate low‑speed in‑vehicle communication, along with built-in multi‑level protection mechanisms. Furthermore, this series features multiple high-side outputs, high‑voltage GPIOs, and wake‑up input ports, meeting the requirements for automotive load driving, signal acquisition, and multi‑source wake‑up interactions.
3. Comprehensive, multi-dimensional security monitoring to enhance the reliability of in-vehicle systems.
It features built-in fault‑safe modules and hardware watchdogs, among other monitoring units, to continuously track the device’s operating status. Equipped with over‑temperature and short‑circuit protection, it mitigates the risk of damage under complex operating conditions. A 16‑bit SPI interface enables flexible parameter configuration and rapid fault diagnosis, facilitating fault localization and root‑cause analysis, thereby significantly enhancing the reliability of in‑vehicle systems.
4. Multi-mode power management, tailored to meet low-power requirements across all use cases.
Six standard operating modes enable hierarchical control of the power supply status. In sleep mode, the main power can be shut down to reduce static power consumption; the remaining modes are tailored to scenarios such as hibernation and wake-up, as well as fault‑induced restarts, thereby effectively extending the service life of the vehicle’s battery.
Li Wenxiong, Vice President of GigaDevice and General Manager of the Automotive Business Unit, stated: “The automotive electrical and electronic architecture is undergoing rapid transformation, posing challenges to system design such as increasing integration and reducing power consumption. GigaDevice’s newly launched GD33AP236x series SBCs will form a comprehensive solution when paired with the GD32A7x series MCUs, fully meeting the requirements of next-generation automotive electrical and electronic architectures.”
Encapsulation
All SBCs in the GigaDevice GD33AP236x series feature a QFN‑48 package and are available in 12 distinct models.
