Macronix International Co (旺宏電子), the world’s No. 2 NOR flash memory chipmaker, yesterday said STMicroelectronics NV has adopted its ultra-low-power flash memory chips for its new advanced microcontroller (MCUs) used in Internet-of-Things (IoT) devices.
It is the latest move by Macronix to expand its business in the IoT sector.
Macronix said that the IoT is rapidly emerging as one of three new applications that would drive strong demand for NOR flash memory chips and is likely to fuel the chipmaker’s growth.
“Our MX25R Quad-SPI Flash memory [adopted by STMicroelectronics] has a small footprint that is ideal for space-constrained ‘smart’ appliances and devices, and its low power and wide voltage range are tailored to overcoming the challenges of wearable and IoT devices,” Marconix marketing division vice president Ni Fu-long (倪福隆) said in a company statement.
The firm’s MX25R6435F is manufactured on its own 75-nanometer process technology under the Macronix 10-year Product Longevity Program, the statement said.
STMicroelectronics latest ultra-low-power MCU’s, provisionally named STM32L496/4A6, can be used in a wide range of applications including wearables, industrial sensors, home automation, and audio and metering systems, the statement said.
Apart from IoT devices, Macronix attributed demand for MCUs primarily to cars and growing adoption of organic light-emitting diode (OLED) flat panels for smartphones, which is partly worsening a supply crunch.
The chipmaker said smartphone makers have substituted embedded flash with NOR flash chips, which enhance color performance, for use in flagship models’ OLED panels.
These three applications are projected to each consume 100 million units of NOR flash chips per year, the chipmaker said.
Macronix said it has run its factories at capacity to cope with increasing orders, but still cannot catch up with demand.
It expects supply constraints to continue for the rest of the year.
From the customer’s perspective, car rental is a straightforward business. The only uncertainty is whether the hire company will charge you for the scratch they discover when you hand back the vehicle. Hertz Global Holdings Inc’s bankruptcy protection filing on Friday last week was a reminder that today even the simplest business models are underpinned by a lot more financial complexity than meets the eye. The proximate cause of Hertz’s demise was of course the sudden collapse in bookings caused by COVID-19 travel restrictions. The company’s monthly revenue last month fell 73 percent year-on-year, a shortfall that even the most resilient
Uber Technologies Inc, Lyft Inc and Airbnb Inc have slashed thousands of jobs. Salesforce.com Inc and Visa Inc are letting employees work remotely for months; Twitter Inc and Square Inc are allowing them to do so for good. For the companies’ hometown of San Francisco, the moves are early signs of a dire blow. In a city with a long history of booms, busts and natural calamities, the COVID-19 pandemic has suddenly upended nearly a decade of prosperity. While municipalities across the US are grappling with economic fallout from the virus, San Francisco stands to take a deeper hit given its high
BULK PURCHASE: The French chain and Hong Kong-based Dairy Farm International reached a deal covering 224 stores, which is expected to be finalized by year’s end Carrefour SA yesterday announced it would acquire Wellcome Taiwan Co (惠康百貨) for 97 million euros (US$108.33 million), and bring all the Wellcome supermarkets (頂好超市) and Jasons Market Place stores nationwide under its banner within 12 months of the deal closing. The France-based hypermarket chain reached an agreement with Hong Kong-based Dairy Farm International Holdings (牛奶國際控股), the pan-Asian retailer that launched Wellcome Taiwan in 1987. The transaction involves 199 Wellcome supermarkets, which have average sales areas of 420m2 and 25 high-end Jasons Market Place stores, which have an average sales area of 820m2, as well as a warehouse in Taoyuan, Carrefour Taiwan (家樂福)
‘ONE-STOP SHOP’: A Miaoli official said that the factory in the Jhunan section of the Hsinchu Science Park would create more than 1,000 jobs and boost prosperity A new high-end IC packaging and testing plant planned by contract chipmaker Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) in Miaoli County is expected to start operations in the middle of next year, Miaoli County Commissioner Hsu Yao-chang (徐耀昌) said. Hsu wrote on Facebook that TSMC, the world’s largest pure wafer foundry operator, would invest NT$303.2 billion (US$10.1 billion) to build the plant, the largest-ever single investment in Taiwan. However, TSMC declined to disclose the financial terms of the deal, while a company board meeting on May 12 approved a spending plan worth NT$168.2 billion as part of its investment plans.
