Realtek Brand Guidelines: The Hsinchu Chip Designer Behind the “Crab Card”

A fabless start in Taiwan’s science park.

Realtek began in October 1987 in the Hsinchu Science Park, the technology district in northern Taiwan. Chinese Wikipedia gives the founding date as 21 October 1987 and says the company was set up by a group of seven engineers together with outside investors, starting with chips for consumer electronics and computer peripherals. The Taipei Times, in a July 2021 report, described it as a company “founded in 1987 at the Hsinchu Science Park” and a fabless semiconductor firm — a chip designer that relies on outside foundries to make its wafers.

Networking came early. Chinese Wikipedia says that in 1991 Realtek introduced the RTL8002, a pocket Ethernet controller that it calls the first such chip developed in Taiwan, and that a 1994 reorganisation split the business into three divisions: communications and networking, computer peripherals and consumer products. English Wikipedia groups its products in the same three ways: communications network ICs, computer peripheral ICs and multimedia ICs. Realtek was listed on the Taiwan Stock Exchange in 1998, according to both Wikipedia editions.

Part of its audio business came from California. English Wikipedia says Realtek acquired Avance Logic, a Fremont company founded in 1991 that worked on 2D graphics and sound chips, as early as 1995, and ran it as an independent subsidiary until it was folded into Realtek at the end of 2002; Realtek’s audio products grew out of that technology, the encyclopedia says, and the old prefixes ALG, for Avance Logic Graphics, and ALS, for Avance Logic Sound, still point to that lineage.

Chinese Wikipedia lists other early markers. It says Realtek became, in September 1995, the first IC design company in Taiwan to receive ISO 9001 certification, and that science-park authorities gave its products innovation awards in 1999 and 2000, including one for an IEEE 1394 physical-layer chip.

Ethernet, audio and the “crab card.”

English Wikipedia describes its RTL8139 series of Fast Ethernet controllers as reaching their height in the late 1990s, and names the RTL8111 Gigabit Ethernet chip and the ALC892 HD Audio codec as favourites of computer makers by 2013. Chinese Wikipedia says a fast Ethernet single-chip controller won Best Component and Best of Show awards at the Taipei computer show, Computex, in 1997.

The brand has an unusual nickname. Both Wikipedia editions say the company’s logo is a crab — Chinese Wikipedia describes a crab device carrying the letters RMC — and that in Taiwan the network cards built on its chips came to be called “crab cards.”

The range has widened since. English Wikipedia records Realtek’s entry into chips for HD media players in 2009, with the 1073 series, followed by the 1186 in October 2011. In February 2021 the Taipei Times reported the company pointing to demand for its Ethernet switch and Wi-Fi chips as people worked and studied from home, along with Bluetooth chips for wireless earbuds and chips for televisions. The company said the same trends were lifting demand for internet surveillance devices and outdoor LED displays that use its Ethernet chips.

The media-player chips show a habit of supplying software as well as silicon. English Wikipedia says the 1073 players all ran on a common software kit provided by Realtek, so that device makers mainly had to build the hardware; the later 1186 added HDMI 1.4 support and could boot into Android. Chinese Wikipedia’s product list also takes in GNSS receivers, Class-D audio amplifiers and PC camera controllers, and Realtek’s download pages offer drivers for Windows, Mac and Linux, English Wikipedia says.

Realtek’s own announcements in autumn 2026 show where it now presents itself: at IBC2026 in September, with an AI home media chip and a streaming-platform chip for set-top boxes; at the China International Industry Fair in Shanghai in October, with industrial Ethernet and robotics solutions; and at Network X 2026, with 2.5-gigabit switching, fibre broadband and Wi-Fi 8 designs.

How fabless chip designers present themselves.

A fabless chip designer has an unusual problem for a brand: its product is a small, dark square that most buyers never see. The company designs the chip, an outside foundry makes the wafers, and the finished part disappears inside someone else’s phone, television, router or car. The visual language of the category grows out of that gap between what the company makes and what anyone can look at.

One answer is the rendering. Chips appear floating above circuit-board landscapes, lit from below, with traces running off toward the horizon like roads seen from the air. Another is the die photograph: a close view of the silicon itself, often tinted in false colour so that memory blocks, processor cores and interfaces read as separate districts on a map.

A third answer is to show the products the chip ends up in. Reference designs — earbuds, security cameras, smart speakers, displays, small smart-home gadgets — let a designer point to a finished object without claiming it as its own. Developer kits and evaluation boards, photographed on desks next to laptops and cables, speak to the engineers who choose components.

The calendar matters too. Much of the category’s public presentation happens at trade shows such as CES in Las Vegas, Computex in Taipei, Embedded World in Nuremberg and the Hot Chips conference, where booths, demo walls and technical papers carry the brand. Many press releases follow the same rhythm, dated from headquarters and timed to a show. The guides that follow look at how individual companies work within these conventions, and at what can be documented about each one.

A crab on the motherboard.

Realtek remains an independent, listed company headquartered in the Hsinchu Science Park. As a fabless designer it does not run its own wafer plants; in February 2021 the Taipei Times quoted its spokesman saying there were “no signs” of an easing in the imbalance between wafer supply and demand, and that Realtek would work with clients on the issue.

It has kept building at home. In July 2021 Taiwan’s Ministry of Economic Affairs said Realtek planned new office buildings at the Hsinchu Science Park and at the Hsinchu Biomedical Science Park in Jhubei, in Hsinchu County, to house IC designers, software and hardware researchers, laboratories and small-scale trial production, the Taipei Times reported. The ministry expected the project to create 545 jobs, and said Realtek was one of five local companies approved that month to join the government’s three-year action plan for domestic investment.

Its press releases are dated from Hsinchu and written in an engineering register: product families, interface standards and trade shows rather than consumer slogans.

For a design guide, Realtek shows how a component brand can become familiar through a nickname rather than advertising. Compare MediaTek, another Hsinchu chip designer, and Novatek, its science-park neighbour in display chips. For this guide we use a deep network blue, a coral and a pale board grey with a sans, an unofficial interpretation; no product or logo is reproduced.
