New Product Recommendation: GigaDevice Launches the GD33AP236x Series Automotive‑Grade SBCs
GigaDevice has announced the launch of its new GD33AP236x series of automotive‑grade system basis chips (SBCs). This family integrates a low‑dropout regulator (LDO), a power management unit (PMU), a CAN FD transceiver, and a LIN transceiver, all compliant with the AEC‑Q100 Grade 1 automotive reliability standard. The products are well suited for mainstream body‑electronics applications, including body domain controllers (BDC), body control modules (BCM), lighting control, and HVAC controllers. The GD33AP236x SBCs can be paired with the company’s existing GD32A5x and GD32A71x automotive‑grade MCUs to form system‑level solutions, further strengthening GigaDevice’s product portfolio and market presence in the automotive electronics sector.
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 core power to automotive‑grade MCUs.
LDO2: Auxiliary regulated output, providing a 5 V output with a maximum current of 100 mA. It features 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 likewise features off‑board protection functions.
Combining superior performance, it covers a wide range of body control applications.
The GD33AP236x series combines multiple outstanding features, including communication, security, and power‑consumption management, and supports a wide range of body‑control applications.
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 communications, 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.
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.
Multi-mode power management, tailored to meet low-power requirements across all scenarios.
Six standard operating modes enable hierarchical control of the power supply status. In sleep mode, the main power is shut off 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.
The GD33AP236x series SBCs all feature a QFN‑48 package and are available in 12 distinct models. Together with the GD32A7x series MCUs, this SBC lineup delivers a comprehensive solution that fully addresses the requirements of next‑generation automotive electrical and electronic architectures.
