The MC68882EI20A is manufactured by Motorola. Motorola, Inc. was historically known for its role in the development and manufacturing of semiconductors, telecommunications equipment, and other electronic products. The company was originally founded in 1928 and became a key player in the electronics and communication industries, contributing to significant technological advancements. Its semiconductor division, which produced the MC68882, was involved in the development of microprocessors, microcontrollers, and other integrated circuits.
In 2004, Motorola's semiconductor business was spun off to form a separate company called Freescale Semiconductor, which continued to manufacture and develop semiconductor products. Freescale was later acquired by NXP Semiconductors in 2015. NXP is a global semiconductor company known for providing a wide range of products, including those used in automotive, industrial, and consumer applications. Therefore, while the MC68882EI20A was initially manufactured by Motorola, the legacy of its semiconductor business now continues under NXP Semiconductors.
