GD32E512 Series: Designed for High-Speed Optical Module Applications

Targeting the demanding requirements of high-speed optical modules, the GD32E512 series features a high-performance Arm Cortex®-M33 core operating at up to 120 MHz. The series introduces integrated I3C support, enabling high-bandwidth, low-latency, and high-density communication to meet the evolving requirements of next-generation optical modules.

The GD32E512 series is available in an ultra-compact 3 × 3 mm package, helping customers optimize PCB space and support the ongoing trend toward higher integration and miniaturization in optical module designs.

To further simplify system design, the GD32E512 series integrates a rich set of application-oriented peripherals, including 3× I²C, 1× MDIO, 2× ADC, 4× DAC, 2× comparators (COMP), and 2× operational amplifiers (OPA), providing comprehensive monitoring, control, and management capabilities for high-speed optical module applications.

GD32E252 Series: Optimized for Low-Speed Optical Module Applications

The GD32E252 series is specifically designed for low-speed optical module applications and is built around the Arm Cortex®-M23 core. Through continuous optimization, the series delivers enhanced analog performance while maintaining a high level of integration, low power consumption, and reliable operation.

Designed to address the requirements of access networks, industrial optical communications, and other cost-sensitive optical connectivity applications, the GD32E252 series provides an optimized balance of performance, integration, and efficiency. The devices also feature compact package options, wide-temperature operation, and strong EMC performance, helping customers simplify system design, reduce development complexity, and accelerate time-to-market.

Enabling the Future of High-Speed Optical Connectivity

The introduction of the GD32E512 and GD32E252 series further expands GigaDevice's optical communication MCU portfolio, providing optimized solutions for both high-speed and low-speed optical module applications. Together, these products address the evolving requirements of AI data centers, cloud infrastructure, telecommunications networks, and access networks.

Looking ahead, GigaDevice will continue to invest in optical communication technologies and expand its application-focused MCU portfolio. Supported by a broad semiconductor product ecosystem and a reliable global supply chain, GigaDevice remains committed to enabling next-generation optical interconnect solutions and supporting the continued growth of AI computing, cloud services, and high-speed networking infrastructure.

Empowering Optical Interconnect Innovation, GigaDevice Unveils Dedicated MCUs for Optical Modules.

NEW YORK (AP) — The U.S. stock market is recovering some of its losses for the week on Thursday, as the roller coaster for artificial-intelligence companies turns back upward. They also got some help from easing oil prices and Treasury yields, which relaxed the pressure even though worries are rising about the war with Iran and accelerating inflation.

The S&P 500 added 0.6%, coming off a back-to-back drop that yanked it back to where it was in early May. The Dow Jones Industrial Average was up 373 points or 0.7%, as of 10 a.m. Eastern time, and the Nasdaq composite was 0.8% higher.

AI stocks helped lead the market, as they have since last week then they went from roaring to records to suddenly turning lower. The big concern is whether such stocks shot too high, too fast because of AI mania, and they’ve been careening up and down, sometimes hour by hour.

Marvell Technology jumped 4.3%, for example. It’s coming off a manic stretch where it plunged 16.7%, soared 9.6% and then fell more than 5% for two straight days. Just before that, it had a one-day surge of 32.5% that was its best in history when Nvidia CEO Jensen Huang suggested it could be “the next trillion-dollar company.” It’s now worth a bit more than $220 billion.

Companies in the chipmaking industry jumped to some of the market's biggest gains. Intel jumped 10.4%, and Applied Materials climbed 8%.

That helped offset a drop of 10.3% for Oracle. It reported a stronger profit for the latest quarter than analysts expected, but it also said it expects to raise $40 billion in cash this fiscal year through borrowing and sales of its stock. That comes after it raised $48 billion last fiscal year to help pay for AI investments.

Other companies’ stocks have also been punished recently for announcing heavy spending on AI, as the question remains whether all the investment can produce the kinds of profits and productivity that AI proponents are promising.

Oil prices, meanwhile, sank despite the latest fighting in the war with Iran, which has hurt the flow of oil deliveries from the Persian Gulf. President Donald Trump threatened to launch major strikes on Iran and seize control of its oil and gas industries.

The United States and Iran have launched attacks over the past several days after a more than monthlong tenuous ceasefire. While the strikes have escalated tensions in the region, they have been more limited compared to the early weeks of the war and talks aimed at extending the ceasefire are ongoing.

Brent crude oil, the international standard, fell 1.1% to $92.08 per barrel. U.S. benchmark crude oil slipped 0.6% to $89.52 per barrel.

High oil prices have sent inflation higher, and a report on Thursday showed that prices at the U.S. wholesale level increased by more in May than economists expected. The effect is worldwide, and the European Central Bank on Thursday became the first major central bank to raise interest rates in response.

Higher rates can keep a lid on inflation. But they also simultaneously slow entire economies and undercut prices for all kinds of investments, including stocks and cryptocurrencies. They hit investments seen as the most expensive in particular, and some critics are calling AI a bubble where investment inflated too far.

The Federal Reserve will make its own decision on interest rates next week under its new chair, Kevin Warsh. He was appointed by Trump, who has been pushing for lower interest rates. But the widespread expectation is that the Fed will keep its main interest rate steady next week. If anything, traders see the Fed as more likely to raise rates at least once by the end of the year, according to data from CME Group.

The yield on the 10-year Treasury eased to 4.52% from 4.55% late Wednesday.

In stock markets abroad, indexes rose modestly in Europe following a mixed finish in Asia.

London’s FTSE 100 rose 1%, and Hong Kong’s Hang Seng fell 0.7% for two of the world’s bigger moves.
