Microchip Technology is an American manufacturer of microcontroller, memory and analog semiconductors. Its products include microcontrollers (PICmicro, dsPIC / PIC24, PIC32, AVR, AVR32 and SAM), Serial EEPROM devices, Serial SRAM devices, KEELOQ devices, radio frequency (RF) devices, thermal, power and battery management analog devices, as well as linear, interface and mixed signal devices. Some of the interface devices include USB, ZigBee/MiWi, Controller Area Network, LoRa, SIGFOX and Ethernet.

Corporate headquarters is located at Chandler, Arizona with wafer fabs in Tempe, Arizona, Gresham, Oregon and Colorado Springs, Colorado, assembly/test facilities in Chachoengsao, Thailand. Sales for the fiscal year ending on March 31, 2016 were $2,173,334,000.

Among its chief competitors are Analog Devices, Infineon, Maxim Integrated Products, NXP Semiconductors (previously Philips and purchased Freescale), Renesas Electronics, STMicroelectronics, and Texas Instruments.

Microchip Technology was founded in 1987 when General Instrument spun off its microelectronics division as a wholly owned subsidiary. Microchip Technology became an independent company in 1989 when it was acquired by a group of venture capitalists, and went public in 1993.

In April 2009, Microchip Technology announced the nanoWatt XLP Microcontrollers (With World’s Lowest Sleep Current). Microchip Technology had sold more than 6 billion microcontrollers as of 2009.

In April 2010, Microchip acquired Silicon Storage Technology (SST), and sold several SST flash memory assets to Greenliant Systems in May that year.

As of 2011, Microchip Technology ships over a billion processors every year. In September 2011, Microchip Technology shipped the 10 billionth PIC microcontroller.

In August 2012, Microchip acquired Standard Microsystems Corporation (SMSC). Among SMSC's assets were those it had previously acquired from Symwave, a start-up that specialized in USB 3.0 chips, and two hi-fi wireless audio companies — Kleer Semiconductor and Wireless Audio IP BV.

In January 2016, Microchip agreed to buy Atmel for $3.56 billion. JPMorgan Chase advised Microchip while Qatalyst Partners advised Atmel.

Microchip develops a wide range of microcontrollers and integrated circuits (ICs), for the hobbyist and professional markets.

Microchip is widely known for their line of PIC microcontrollers, and their MCU-related product line includes:

The Microchip product line of integrated circuits include:

HI-TECH Software was an Australian-based company that provides ANSI C compilers and development tools. Founded in 1984, the company is best known for its HI-TECH C PRO compilers with whole-program compilation technology, or Omniscient Code Generation (OCG). HI-TECH Software was bought by Microchip on 20 February 2009, whereupon it refocused its development effort exclusively on supporting Microchip products.

Silicon Storage Technology, Inc. (SST) was a Sunnyvale, California, United States, technology company producing non-volatile memory devices and related products. SST supplied NOR flash and other integrated circuits for high-volume applications.

Bing Yeh co-founded SST in August 1989, and served as its chief executive.

At the 1992 Fall COMDEX trade show, SST introduced the first single-board 30 MB 2.5” solid-state drive with standard hard-disk ATA interface and a 5 MB PC Card memory card with built-in controller and firmware.

In 1993, SST moved its headquarters to Sunnyvale. That same year, SST introduced its first SuperFlash technology products, with lower costs and faster write speeds. By the end of 1995, more than 90% of the PC motherboards produced in Taiwan had adopted SST's 1 Mbit SuperFlash EEPROM product for the BIOS storage. The company had its initial public offering November 21, 1995, trading on the NASDAQ market under the symbol SSTI. Analytical models of SuperFlash were published. A five-year licensing agreement was announced in January 1999 with Acer Inc.. A 1997 lawsuit filed by Intel was settled in May 1999 after mediation.

In 2004, SST began to diversify beyond flash memory products, targeting consumer and industrial products with embedded solid-state data storage and RF wireless communication. In September 2004 SST purchased a majority stake in Emosyn, which designed products for SIM cards. In October it announced the acquisition of G-Plus, based in Santa Monica, California.

In 2006, SST announced a joint development agreement with Taiwan Semiconductor Manufacturing Company (TSMC) to develop 90 nm SuperFlash technology.

SST had its stock option grant practices investigated by the US Securities and Exchange Commission, ending in June 2008. It determined it needed to restate earnings, and was given a de-listing notice by NASDAQ for filing late reports from 2006 through 2007. Business slowed in the Great Recession.The company announced a loss on reduced revenues, reducing its workforce by 17% in December 2008.

In November 2009, Technology Resource Holdings offered to acquire the company for about $200 million, but a group of shareholders thought it was undervalued. Starting in February 2010, private equity firm Cerberus Capital Management and public company Microchip Technology both made offers to acquire SST. In April 2010, Microchip completed the acquisition for about $292 million. Microchip sold several SST flash memory assets to Greenliant Systems (founded by Yeh) in May of that year.
