Zilog Z80 8-Bit CPU Turns 50, Open-source Replacement Heads To Drop-in DIP40 Silicon

An anonymous reader shared this report from Tom's Hardware: The Zilog Z80 has just turned 50 years old. This iconic 8-bit processor first went on sale in July 1976 and stayed in production for 48 years until Zilog, now a Littelfuse subsidiary, stopped accepting orders in June 2024. However, there's an open-source replacement closer than ever to shipping in the chip's original 40-pin DIP package thanks to community-funded fabrication... The chip powered the ZX Spectrum, TRS-80, MSX machines, Nintendo's Game Boy, Sega's Master System, the Pac-Man arcade cabinet, and Texas Instruments' graphing calculators, then shipped in industrial controllers for decades after home computing moved on to more powerful successors. Zilog's end-of-life notice, dated April 15, 2024, told customers its wafer foundry was discontinuing support for the Z84C00 family, and last-time-buy orders closed that June. However, Renaldas Zioma's FOSS Z80 project, launched shortly after the end-of-life notice, now has working silicon. The first version, fabbed on SkyWater's 130nm node through Tiny Tapeout 7 on a die of just 0.064mm(2), has been confirmed as functional via the project's GitHub repository. A QFN64 version with all 40 pins exposed followed on the Efabless CI2406 shuttle, two further runs then went through IHP's 130nm process, and the current run targets the classic DIP40 form factor using chip-on-board assembly on GlobalFoundries' 180nm GF180MCU node via Wafer.Space. The end goal here is to fab a drop-in replacement for machines like the ZX Spectrum and RC2014 kits... Zilog is trimming the Z80's official successor line as well. A product change notification from last October put the eZ80L92, along with several Z8F-series microcontrollers, on end-of-life, citing "little to no demand..." [T]he pipelined eZ80 architecture, introduced in 2001 and still inside TI's current TI-84 Plus CE calculators, otherwise remains in Zilog's catalog. In 1999 Slashdot was calling Zilog's updated eZ80 "one of the fastest 8-bit CPUs available today, executing code 4 times faster than a standard Z80 operating at the same clock speed." Slashdot headline from 2001: Zilog To File For Chapter 11.

OpenAI's First Device Will Be Moveable, Screenless Speaker Built as AI Companion

OpenAI is reportedly developing a screen-free, portable smart speaker meant to act as a personalized home computer and humanlike AI companion. "It will help control smart-home appliances, play media, answer questions, respond to messages and tap into the range of capabilities offered by OpenAI's ChatGPT," reports Bloomberg, citing people familiar with the matter. The device, expected to be unveiled this year and released in 2027, would mark OpenAI's first major hardware push after acquiring Jony Ive's io Products. Bloomberg reports: Apple sued OpenAI last week, accusing the company of stealing trade secrets. But OpenAI believes that the device veers significantly from anything Apple has on the market today and that it's unlikely that it violates trade secrets belonging to the iPhone maker, the people said. OpenAI's success in hardware will hinge on bringing a novel approach to the market -- something it aims to do with the smart speaker. For instance, the device's technology is meant to become increasingly personalized and proactive as it gains a deeper understanding of its owner over time, according to the people. OpenAI envisions the device anticipating needs, surfacing information proactively and serving as an expert on its user, they said. Though the speaker is designed to stay in the home, it will be easy to move around the house. OpenAI believes the product's defining feature will be its personality and ability to connect on a humanlike level with users. The speaker incorporates mechanical elements that can move on their own, creating a sense that it is alive and not just an object responding to commands. The machine also will draw on personal information such as emails to better understand its owner. The goal is for the device to feel like a companion and become a physical manifestation of OpenAI's ChatGPT. Still, the exact plans could change as the company works through the development and legal process. The device's communication abilities will rely on a more advanced version of the ChatGPT Voice Mode -- GPT-Live -- that OpenAI rolled out this month. The new voice mode is designed to act more like a human. It can listen and talk at the same time, adapt more naturally during conversations, and quickly process information. Though the new product resembles a speaker, OpenAI internally describes it as the first of its kind: a computer built for AI to help make busy people more productive. It includes a camera and other sensors that help it understand a user's surroundings and context, as well as advanced AI models beyond those available on conventional smart speakers. Another central difference is that the device includes a rechargeable battery, allowing it to be carried from room to room throughout the day. A user could bring it into the laundry room while doing chores, move it into the kitchen for cooking assistance, and later place it in a living room or bedroom to have it play music. It can also remain plugged into a single room if the customer chooses.

SK Hynix CEO Warns 2027 Will Be Memory's 'Worst Year' Ever. Shortages May Outlast the Decade

The CEO of SK Hynix, one of the three largest DRAM producers, predicted to Reuters that the memory industry will see its "worst-ever" supply shortages in 2027, reports the hardware/gaming news site Wccftech: SK Hynix has also forecasted that, given the current market demand, they will fall way short of fulfilling the market demand, and that will continue beyond 2030. The comments from SK Hynix are in line with what Samsung and Micron executives have already said. Samsung has warned of 2027 being the worst year in terms of shortages and that things will continue this way till 2028 and beyond. Meanwhile, Micron has said that the current shortages are only the "first innings" and that both DRAM/NAND supply will be tight, as they are only able to meet 40-50% of the total market demand in the coming years. Heightened demand from AI customers and multi-year agreements further put pressure on the market. The big three DRAM makers have already prioritized premium DRAM segments such as HBM and LPDDR5X, while commodity memory such as DDR5, DDR4, and entry-level LPDDR RAM has taken a back seat. While these have boosted the profits of SK Hynix, Micron, and Samsung, they have devastated the consumer segment, which is facing the worst kind of price hikes that are affecting all sorts of components and platforms, including PCs, Smartphones, Consoles, etc... SK Hynix, like Samsung and Micron, is also preparing to embark on a multi-year and multi-billion dollar expansion plan with new fabs and facilities being laid out across South Korea. SK Hynix is also considering the construction of Fabs in the US, Japan, and Southeast Asia, though the final plans are yet to be cemented. Micron recently started construction of its new facility that will be used for DRAM production. As SK Hynix proudly marks its Nasdaq debut, its CEO's sobering forecast serves as a clear reminder: the memory industry is entering its most challenging chapter yet. With 2027 poised to bring the worst supply shortages in history and tight conditions likely persisting beyond 2030, the AI boom is reshaping the entire semiconductor landscape.
