Wuhan Xinxin Semiconductor Manufacturing (XMC), under China's state-owned Tsinghua Unigroup, has reportedly kicked off mass production of its in-house developed 50nm SPI NOR flash chips.

XMC introduced its new SPI NOR flash series built using its own 50nm floating-gate technology in December 2019. The series' transfer rates can outperform standard 8- and 16-bit parallel flash memories, with continuous read mode allowing for efficient memory access with as few as 8-clocks of instruction-overhead to read a 24-bit address, enabling XIP (execute in place) operation.

XMC disclosed the new XM25QWxxC supports SOP8 and USON8 packages, which can help customer develop products with compact physical dimensions. "This product series marks a key milestone of XMC's own brand strategy to expand its high-performance memory portfolio by continuously developing innovative products for the always growing IoT market in the future," said Holly Sun, company VP of operation, in a statement.

Founded in 2006, XMC is a 12-inch foundry focusing on R&D and manufacturing of NOR flash, CMOS image sensor chips and MCU.
