Spansion是全球行业领先的嵌入式市场闪存解决方案创新厂商，2013年收购了富士通半导体公司的微控制器和模拟业务部门后，Spansion公司的产品线扩充为闪存、通用MCU、汽车电子MCU、模拟（包括模拟器件、电源管理、混合信号），具备了提供完整的嵌入式解决方案的能力。汽车电子是Spansion公司重要的独立业务部门，营收占公司总体营收的30%以上，而且未来仍将是Spansion公司的核心应用市场。

Spansion 飞索半导体--全球最大的专门从事闪存开发、生产和营销的高科技跨国企业，面向市场提供最丰富、最全面的闪存产品。于2003年由AMD和富士通整合各自的闪存业务合并成立，并且继承了双方长期以来的技术创新和市场领先地位。目前，产品主要应用于通讯、汽车、网络和消费电子等领域，在NOR型闪存的市场占有率处于世界领先地位。2005年12月飞索半导体（Spansion，SPSN）完成分拆并在纳斯达克成功上市。目前在世界各地员工总数约有8500人。

Spansion –闪存行业的领导者,根据市场研究机构iSuppli公司的数据，飞索半导体（Spansion）已经超过了英特尔公司，在NOR闪存市场上，Spansion 飞索半导体的增长率超过了去年整个市场的增长率，达到35％，销量达到18亿美元。去年整个市场的增长率为16.4％，总产值61亿美元,这样的佳绩让Spansion 飞索半导体以29.9％的市场份额跃居头名。英特尔以26.1％的份额紧随其后，接着是15.7％的意法半导体和11.2％的三星电子。东芝公司则以6.5％的市场份额位列第五。iSuppli公司的高级分析师Mark DeVoss表示，Spansion 飞索半导体之所以表现如此出色，原因是公司向一线的手机厂商的供货不断的增加，此外Spansion 公司在日本和亚太地区市场上的份额大幅增加。在2005年英特尔是NOR闪存行业的王者，市场份额为28.9％。但去年Spansion 公司在手机的闪存芯片的市场上的销量仅仅增长了5.1％，总的年销量方面仅从2005年的15亿美元增长为16亿美元。Spansion 飞索半导体在销量方面的优异表现让公司在闪存市场上一跃而上位居第三了。但状元三星电子和榜眼东芝公司的地位依然稳固，两家公司在NAND闪存市场的出色表现依然瞩目。英特尔则连续下跌，从2005年的第三到2006年的第五。

Spansion 致力于为汽车、消费电子、网络和无线市场创建、保存和保护数字内容。作为全球最大的专门提供闪存解决方案的公司，Spansion目前提供了市场上最丰富、最全面的闪存产品线。

Spansion公司的所有业务都围绕着集成电子产品市场，即将闪存集成在设备内部。在这个市场中，客户注重的是那些具有较高性能和质量，富有特色的系统。集成市场中使用Spansion闪存产品的主流客户包括汽车电子、消费电子和手机领域的前十大原始设备制造商。

通过先进的技术成果――例如屡获大奖的MirrorBit技术，Spansion公司成功地开发出了很多经济有效、外型更加小巧、功能更加强大的产品。它们采用了独特的设计，可以实现可靠的代码执行和数据存储。通过提供用于代码的NOR架构和用于可扩展数据存储的ORNAND架构，Spansion的客户可以使用一个统一的平台，对不同的应用进行必要的数据容量扩展。

先进的制造能力、四个专门的闪存晶圆制造厂和一个开发中心让Spansion 可以更快地推出下一代技术。因此，Spansion公司已经开发出了一些高度可扩展的解决方案，它们为采用未来的产品和技术提供了一条平稳的移植途径，以满足客户不断发展的要求。

2014年12月，Spansion被Cypress并购。

Spansion Inc. was an American-based company that designed, developed, and manufactured flash memory, microcontrollers, mixed-signal and analog products, as well as system-on-chip (SoC) solutions. The company had more than 3,700 employees in 2014 and is headquartered in Sunnyvale, California. Spansion is a former joint-venture between AMD and Fujitsu. In August 2013, Spansion closed the acquisition of the Microcontroller and Analog Business of Fujitsu Semiconductor Limited.

Spansion has more than 10,000 customers worldwide. Its products are used in the following markets: automotive electronics, home appliance, peripheral computing equipment, consumer equipment, industrial and networking.

History
Spansion was founded in 1993 as a joint venture between AMD and Japan's Fujitsu Ltd. Spansion was formerly known as FASL LLC. Once AMD took control of the company in 2003, it was renamed Spansion LLC in June 2004 and officially spun off as an independent maker of flash memory chips in December 2005.

After joining the company in 2009, CEO, John Kispert, brought Spansion out of bankruptcy with over $1 billion in sales and 10,000 customers worldwide. In 2013, Spansion purchased Fujitsu’s microcontroller and analog business for $175 million, expanding Spansion’s work force by more than 1,000 worldwide.

Mergers and acquisitions
In October 2007, Spansion announced that it was acquiring Israel-based Saifun Semiconductors Ltd., non-volatile memory provider. The companies signed an agreement that consolidated all MirrorBit and NROM IP, design and manufacturing expertise within Spansion. As a result, Spansion expanded IP portfolio and enabled its immediate entry into the technology licensing business. The acquisition closed on March 18, 2008.

In April 2013, Spansion announced that it would acquire the Microcontroller and Analog Business of Fujitsu Semiconductor for approximately $110 million and approximately $65 million for inventory. Spansion closed the acquisition deal in August 2013.

In December 2014, Cypress Semiconductor merged with Spansion in an all-stock deal worth $1.59 billion. Shareholders of each side will own about 50 percent of the new company, which will keep the name of Cypress Semiconductor Corp. The companies valued the deal at $4 billion. They expected it to close in the first half of 2015 and to cut annual costs by $135 million within three years. Cypress President and CEO TJ Rodgers was the CEO of the combined company, which was expected to have $2 billion in annual revenue. Spansion Chairman Ray Bingham was the non-executive chairman.

Spansion's product portfolio offers NOR densities ranging from four-megabit to eight-gigabits, NAND densities ranging from one-gigabit to eight-gigabits and an array of interfaces and features. It has developed two flash memory technologies, single-bit-per-cell floating gate technology and one-, two- or more-bit-per-cell MirrorBit technology, with MirrorBit products based on two-bits per cell and allow offering a range of product configurations. The Company's products based on NOR flash memory architecture are designed for code storage and execution, and utilize either traditional floating gate technology or its MirrorBit technology.

Spansion’s NOR and NAND offering is targeted at embedded applications such as automotive, industrial and telecommunications.

Spansion concentrates on the embedded electronics market. Its Floating Gate and MirrorBit technology is used to make networking and telecommunications equipment, consumer electronics, gaming equipment, TV set-top control boxes, automotive equipment and personal computer peripherals.

The company’s NOR products offer designers the option to choose from 5V, 3V and 1.8V products that range from 1Mb to 2Gb.NAND products offer 3V and 1.8V products that range from 1Gb to 8 Gb.

Spansion’s standard parallel NOR flash includes Spansion’s MirrorBit NOR GL, AL AS, CD-CL, F, JL, PL, NS/VS/XS and WS families of flash memory. The products operate anywhere at 1.8 to 5.0 volts (Vcc), feature a random read speed of 90-100 nanoseconds (ns) access and offer a page read speed of 25 ns via an 8-word page buffer.

Spansion’s serial peripheral interface (SPI) devices read information serially, or one bit at a time, requiring fewer connections and pins, allowing for lower costs and simplified board layouts. Serial flash memory is used in applications such as high-end printers, FPGAs, networking equipment and set-top boxes.

The Spansion SPI FL family of serial flash memory: Densities for the SPI flash memory devices range from 4 Mb to 1 Gb with uniform 4KB uniform 64KB and uniform 256KB (128Mb – 1Gb FL-S) sectors and 4 Mb with parameter sectors. 

Spansion developed the HyperFlash NOR memory devices, based on the HyperBus interface. The family features read throughput of up to 333 megabytes per second—more than five times faster than ordinary Quad SPI flash currently available with one-third the number of pins of parallel NOR flash. Spansion HyperFlash memory devices provide a migration path—from single Quad SPI to Dual Quad SPI to HyperFlash Memory—allowing system applications to be scaled to different levels of flash performance when paired with compatible controllers, giving OEMs the ability to offer different product models with a single design.

In August 2011, Spansion announced that it had created the first single-die, 4-gigabit NOR product implemented at the 65-nm node.

In 2013 Spansion acquired the Fujitsu microcontroller and analog business, including 8- 16- and 32-bit microcontroller families.

Spansion’s FM MCU microcontroller family, which is based on the ARM Cortex-M4, M3, M0+ CPUs comes in packages from 32 to 216 pins, with flash memory densities between 56KB and 2MB. The Spansion Traveo microcontrollers are based on the ARM Cortex-R5 core and the first series in the Traveo family, MB9D560, operate at 200 MHz. 

Spansion also acquired power management ICs aimed at energy harvesting and LED lighting.  The Buck PMIC for solar and vibrations energy harvesting MB39C811regulates output voltage with the quiescent current of 1.5µA. The Boost PMIC for solar and thermal energy harvesting MB39C831. Spansion’s Easy DesignSim is a comprehensive online design support tool for LED Driver Circuit designers.
