[{"type":"text","content":"SST’s innovative ESF4 delivers full auto grade 1 performance and reliability for automotive controllers on UMC’s 28HPC+ process platform while using significantly fewer masking steps\nSAN JOSE, Calif. and HSINCHU, Taiwan, Jan. 15, 2026 (GLOBE NEWSWIRE) -- As the automotive industry requirements for increasingly performant vehicle controllers relentlessly drives ahead, Silicon Storage Technology® (SST®), a subsidiary of Microchip Technology Inc., (Nasdaq: MCHP) and United Microelectronics Corporation (NYSE: UMC: TWSE: 2303)(“UMC”), a leading global semiconductor foundry, announced today that they have completed full qualification and release to production of SST’s embedded SuperFlash® Gen 4 (ESF4) with full automotive grade 1 (AG1) capability on UMC’s 28HPC+ foundry process platform. SST developed ESF4 in close partnership with UMC to deliver enhanced embedded non-volatile memory (eNVM) performance and demonstrated reliability for automotive controllers while simultaneously significantly reducing the number of additional masking steps versus other foundries’ 28nm High-k/Metal-Gate Stack (HKMG) eFlash offerings, bringing customers cost advantages and greater manufacturing efficiency. Customers currently manufacturing automotive controller products using foundry 40nm ESF3 AG1 platforms are encouraged to explore the UMC 28nm ESF4 AG1 platform as they look to scale to the next process node. “As automotive requirements accelerate, developers need solutions that drive efficiency, speed up time to market and satisfy stringent industry standards. To meet these needs, UMC and SST have delivered a robust 28nm AG1 solution which is now ready for the production of customer designs,” said Mark Reiten, Vice President of Microchip’s licensing business unit. “UMC has been a valuable partner for SST and SuperFlash innovation, and the companies continue to jointly address the rapidly evolving market requirements and deliver technically and economically advanced offerings.” “As the automotive industry rapidly advances toward more connected, autonomous, and shared vehicles, the demand for highly reliable data storage and high-capacity data updates continues to grow. This has driven customer demand for scaling SuperFlash to the 28nm process,” said Steven Hsu, Vice President of Technology Development at UMC. “Through our close collaboration with SST, ...
