MCUs optimize control in optical modules
GigaDevice offers the GD32E512 and GD32E252 MCUs purpose-built for high-speed and low-speed optical modules, respectively. The devices target applications in AI data centers, cloud infrastructure, telecommunications networks, and access networks.
The GD32E512 features an Arm Cortex-M33 core operating at 120 MHz and integrates I3C support for high-bandwidth, low-latency, high-density communications in next-generation optical modules. Its peripheral set includes two 12-bit ADCs, up to eight 12-bit DACs, two comparators, two op amps, three I²C interfaces, and one MDIO interface, enabling monitoring, control, and management functions in a compact 3×3-mm chip-scale package.
Powered by an Arm Cortex-M23 core operating at 72 MHz, the GD32E252 delivers a balance of performance, integration, and efficiency for cost-sensitive and lower-speed optical connectivity applications. The MCU integrates one 12-bit ADC, four 12-bit DACs, one comparator, one I²S interface, and three I²C interfaces in a choice of QFN package options.
